About the application.

Introduction.

It wouldn't be so easy (if ever possible) to find another classic game that would have as many variations as draughts or checkers - from ancient El-Quirkat to modern HexDame. Since a single application to implement all wouldn't probably fit 64K to run on some models, this release implements only the most popular clones that are played on a standard chess board (extended to 10x10 for International draughts) and have some basic common rules.

The application implements:

International draughts
English Draughts (a.k.a. American or Straight Checkers ),
Spanish Draughts (Damas Españolas, or Damas Clásicas)
Russian Droughts  (Russkie Shashki)
Brazilian Draughts (Regras Brasileiras)
Thai Draughts
Pool Checkers
With each variation you can also play give-away mode (known as miserable, gana-pierde, or poddavki in native languages), where the objective is the opposite to the one of  'cannonic' mode.

This versatility along with limited resources has obvious drawbacks:

The application was not really designed to be a champion, the main goal is just to give an idea of  how different rules look like, along with a feeling of  how the differences affect the game logic. Nevertheless, we believe the skills are strong enough to challenge the majority of human players.

Rules

Overview

Draughts most probably appeared as an adaptation of an old Egyptian game known as El-Quirkat(Arabic), or Alquerque(Spanish) to a chess board presumably in 11th century. Alquerque is played on a 5x5 board each having 12 pieces at start with a free spot in the middle. The promotion to a king was probably borrowed from chess, while compulsory capture was introduced near the middle of 16th century.  Also in 16th century the oldest known books on the game were published in Spain:

Antón de Torquemada.
El ingenio, o Juego de marro de punta o Damas.  
Valencia, 1547
"Ingenuity (creativity), or game Strict  Marro , or Draughts".
 
(Does "de punta" refer to compulsory capture?)


Pedro Ruiz Montero.
Libro del juego de damas, vulgarmente nombrado el marro.  Valencia 1591
Here I feel more confident: "A book on game Draughts, informally named Marro" 

If you are completely new to the game,  the following explanation of rules might be insufficient. If this is the case, refer to numerous books and websites. My favourite is http://perso.wanadoo.fr/alemanni  maintained by Jean-Bernard Alemanni, available in English and French. The site provides an accurate description of the rules, information about recent championships and links to other sites. J-B also implemented extremely strong computer programs for a number of draughts variations to run on Microsoft Windows. You can visit the site to learn about his programming secrets, and even get a source code (though for an old version and without any comments). Unfortunately I was unaware of that while developing this product, otherwise it would enormously save my time: I had to repeat all his trials and errors, and my solutions are very similar to what he suggests. The site also provides numerous links to other computer implementations, mostly on same platform as J-B's ones - I wish the 'software monster' to be at least partially as tolerant to their competitors :=)

If you know what the game is about (at least one of its clones),  the following paragraph will explain some of the terms used in this manual (of course you can skip it if you feel confident), followed by a summary of game rules.

Terms

Board and squares

8x8 board - a standard chess board with the white corner at each player's right.
In some books you may find "checkerboard", which refers to a chess board where playable squares are numbered, as opposed to chess style column-row notation. Since we are not interested in any notation, we won't differentiate.

10x10 board - similar to chess board but with 10 rows and 10 columns.
This board is used for International draughts. Because of an increased number of possible moves, a computer move takes more time for International draughts, than for all other variations. If this annoys you, decrease player skill, or choose Brazilian draughts which are effectively International draughts played on an 8x8 board.

Playable square - a square on the board than can be used for placing a piece.
As opposed to chess, draughts use only squares of a particular colour. This implementation always uses black squares for play.

Flipped board - a mirror image of chess board.  A flipped board has the white corner on each player's left.
A common believe that Spanish draughts use a flipped board, may not be 100% accurate. To be honest, I couldn't find official Spanish rules, but as Spanish sources suggest, the board is positioned in usual way,  but white squares are used for placing pieces. In order to follow the rules, and still use black squares for play, a board has to be flipped, and this is what the application does.

Moves

Slide - a move without taking pieces.

Jump or Capture - a move with taking one, or more opponent's pieces.

All rules implemented here require taking opponent's pieces if possible. Some old rules allowed "huff" (if a player failed to capture, the opponent could either remove the piece that should have jumped, or compel the capture), or "blow" (a player who missed the capture looses), which have been officially declared obsolete.

If a piece jumps to a square where it can capture another opponent's piece it must do so and will proceed as long as there are opponent's pieces to capture.

Those were common requirements, while some rules have  additional restrictions and diferent regulations regarding removing_captured_pieces.

Pieces

Man or pawn (pion, pedra, shaska in native languages).  A weaker piece, that can move only one square forward and capture a neighbour opponent's piece. Some rules allow a pawn to capture backward.

King or queen (dama, damka).  When a game starts, each player has only pawns. When a pawn reaches the opposite line, it is crowned by placing another piece of same colour on the top of it (in practice, you can just turn the piece over, but this is not allowed by official rules). A crowned piece is a king. A king can move and capture both forward and backward. In most of the rules a king can move and capture several squares in both directions. See also Crowning rules and King strength.

Additional capture restrictions

These additional rules affect a case when several captures are possible. According to some rules (English, Russian, Thai, Pool) any capturing move can be chosen, while some other variations are more restrictive.

Maximum quantity. According to International and Brazilian rules, you must always take maximum possible number of pieces. For example, you can't select a capture that  takes 1 piece,  if there is a way to capture 2 pieces.  In case there are several ways to take maximum pieces, you can select any.

Maximum quantity and quality: Spanish draughts have a stronger requirement: you still must take maximum possible pieces (maximum quantity), but in case there are several ways to do so, you must take maximum possible number of kings (maximum quality). Only in case there are several ways  to choose a capture according to maximum quantity and quality requirement, you are free to choose any capture.

Removing captured pieces

Instant. According to  Thai rules, a captured piece is removed immediately after it is jumped over.

On completion. Other rules require the all captured pieces must not be removed from the board until capture is complete, however you cannot jump over already a captured piece. As a result of this rule, a captured piece can block a capture, especially in case a  flying king is the capturing piece.

Crowning rules

On completion.  Most of the rules assume that a pawn can be crowned (promoted to a king) only after a move terminates. In case of a sliding move it can't be otherwise, while jumping to the last (king) line is trickier. If the rules allow a pawn to capture back (International, Brazilian) it may happen that a pawn can't stop at the last line because of a need to capture more pieces, in which case it will not be crowned.
Instant crowning. On the contrary, according to the Russian rules a pawn that jumps to the last line is crowned immediately and continues capturing as a king if possible.

King strength

Single-step king. According to English/American rules a king is just a bidirectional pawn: it only can move one square in each direction, or capture a neighbour opponent's piece forward or backward.

Flying king. A flying king  (International, Brazilian, Spanish, Russian, Pool) can move any number of squares along either of two diagonals in both directions, as long as the move is not blocked by another piece of its own or the opposite colour. A flying king can capture an opponent's piece on its way, provided a square immediately after the captured piece is empty. If there are several adjacent (non-interrupted) empty squares after the captured piece, the king can land on any of those.

Short-landing king (Thai). Similar to flying king, but after a capture it must land immediately after the captured piece. This king is obviously weaker (and much easier to trap) than a flying king, but it looks like in case of a strong defence you still cant trap it with less than three pieces.

Draw and move counter.

Draw is a situation when neither of players can win. Unfortunately this isn't pretty obvious to formalise, while the official rules are even less formal (from the computer's prospective) than common sense.

A common approach for a computer program is counting inactive moves which are sliding (i.e without a capture) moves by a king.
Since there doesn't seem to be something better,  we also use this approach.

The application assumes a draw in one the following cases

The values of  M1 and M2 are:

English/American: M1=20,  M2=40
Others:M1=15,  M2=20
Note that the values in the table define the number of moves by each side, therefore total number of half-moves is twice the amount.

To have an idea of how far you are from the draw, check move counter on the status bar. This field shows a decrementing counter value in violet  colour at stage 1 (counting inactive moves),  and pink colour at stage 2 (counting all moves after M1 inactive moves).

For example, assume you play English draughts, therefore stage 1 terminates after  40  consecutive inactive half-moves, and then a player must won in remaining 80 half-moves.

At start you don't see the counter, but after you slide a king you see violet 39,  if  the computer also slides its king, you have 38, and so on. With any active move (capture,  move with a pawn)   the counter is reset, so you don't see it until next inactive move.

If an active move doesn't come,  the counter keeps decrementing until it goes off (to 0) and is replaced by the pink counter (stage 2), which starts from 80 , decrements with each move and is never reset. After the pink counter goes off, a draw is assumed.

Operating the application.

Keys

You operate the application using keys, a joystick, and/or a stylus (pen), whatever is available and preferred.

 The following  list and explains key names used in the manual:
 
Soft  keys Keys usually located just below the screen, and often associated with Menu and  Exit/Back resp. Most of devices have two soft keys: Left and Right. Motorola devices, and Nokia 6650  have an additional Middle soft key (Select) which isn't currently used by this application. For Motorola 388 and 388c soft keys are actually screen buttons which appear only in case they are usable.
Left, Right, Up DownA corresponding arrow key, or moving a joystick in corresponding direction (Nokia 7650).  With Motorola 388 or 388c, use two front keys for Left and Right, side wheel for Up and Down, or use stylus as explained below.
Send (off-hook)This key is usually has a green picture of a handset on it. With Motorola 388 or 388c use side button.
OKSome mobile phones (e.g. 3650) contain OK key in the middle of  the arrow pad,  for 7650 this is pressing a joystick, while for Motorola 388 or 388c  OK functionality is implemented by  the side button.
Where OK key is unavailable, use Send which always has same result.
CLEAR (cancel)A key marked with C,  if unavailable, use  [*]  key
Numeric keysKeys [1] [2],  ... [9], [0] on your keypad
[*]A star (asterisk) key.
[#]A hash (pound) key.

In case a particular arrow key is unavailable, you can use equivalent numeric keys, or tap a screen spot on a touchscreen device (see following sections  for details).

Standard key layout

The following image (Motorola T720) shows the typical location of keys, and the way the keys are used in game:

 Motorola T720 layout

In this case [2] [4] [6], and [8]  are equivalent to Up,  Left,  Right and Down  respectively, [5] key is often equivalent to OK, or Send.

Nokia 3650 keypad

On a Nokia 3650 device, the keys are arranged in a circle :
Layout for Nokia 3650


 This makes inconvenient using the common key layout. With Nokia 3650,  keys [2] and [9] are equivalent to Left and Right keys resp, keys [4] and [7] are equivalent to Down and Up resp, [#] key is normally equivalent to OK, or Send.  If you are confused - never mind: after all you can use arrow keys  without a problem :=)

Imitating keys on a touchscreen device.

The application was designed to work on a touchscreen device even in case no keys are available at all, however keys can also be used if available. As mentioned  previously,  Motorola 388 and  388c devices have front arrow keys corresponding to Left and Right, a side wheel equivalent to Up and Down, and a side button that acts like OK, or Send.

Unless a particular screen spot is used for a specific action (e.g Settings,  Game),  you can imitate pressing a  key by tapping an  appropriate area on the screen, as given by the following diagramme:

1
Up
3
Left
OK
Right
7
Down
9

For example,  to imitate Left key, you need to tap the middle left part of the screen, while Down key is sumulated by touching  the screen in its centre near the bottom edge. 

In case of Motorola 388, or other touchscreen devices where the board does not occupy the whole screen, screen corners can be used similarly to keys [1], [3], [7] in [9] (standard layout)  to specify move by direction .

Before you start a game ...

Panels

The are several intermediate panels: Settings,  Help, About. You can change the current panel, through the Menu ( Left Soft Key), and your preferences are saved in a database - if About panel annoys you (especially for unregistered users), you can easily avoid  it at start :=).

Hopefully someone will find Help pages useful.  Don't forget to scroll using Down and Up, or equivalent. Left and Right keys are used to view previous or next  help page resp. After you leave Help,  the last visited page re-appears next time when you return to Help.

Settings is obviously the most useful panel. Settings are discussed in details in the next paragraph. To change settings, use Up and Down to highlight a parameter you wish to change. Then use Left and Right keys to modify value of  the highlighted parameter.  On a touch screen device, use stylus to highlight the line corresponding to a parameter you want to modify. Tapping already highlighted line modifies appropriate value: tapping left side of the line (line title)  decrements the value,  while touching the right side (line value) increments the value. Settings are saved each time when you start a game, or quit the application.

And the last:  you can start the game at any time by pressing OK, or Send  key.  Pressing Right Soft Key quits the application.

Settings

The default values for each parameter are shown in italic:

Rules: International, English, Spanish, Russian, Brazilian, Thai, Pool.

The rules have been extensively discussed in the  previous chapter.
Give away:  No , Yes
In "cannonic" game (Give away = No) your objective is to leave your opponent without a move by taking/blocking  all opponent's pieces. Alternatively you can select Give away = Yes,  in which case your goal is to remain without moves (someone might argue, that having all your pieces blocked, but not taken, is still a lost game, but this doesn't appear logical and is not the way it has been implemented).  "Loose game" enthusiasts claim  that it requires even deeper thinking than a traditional one. Though I don't argue, for me it has always been a game for fun, and DrgG is not really strong at it. You can play Give Away with any rule.
Time mode:  Move, Game,  Auto
This affects the way time is  displayed in the status bar, which can be either time for the move (Time Mode = Move), or time for current player from start of  the game (Time Mode = Game). Time mode also affects the way Time Limit applies.  In case Time Mode = Auto the actual time mode is selected according to local tradition:   Move with English/American,  and Game with all others.
Time limit: Off, Normal, Blitz
When Off, time is just shown, but doesn't affect the game. Other two settings work according to effective time mode, as given below. Note that in Blitz you cannot take back your move,  and cannot deselect a piece (in accordance with the official rules, where, as in chess, you must move a piece after you touched it,  the application is not as pedantic when  playing a non-Blitz game).

All time intervals below are shown for a human player, while for the computer player the limit  is 1.5 times shorter. This is because a computer player doesn't waste time on key operations :=) 

Time mode Move
Normal:   5 minutes for a move, 1 minute in case only a single move is possible (this is taken straight from US official rules) 
Blitz:    10 seconds  for a move,  2 seconds in case only a single move is possible  
You don't  loose the game if over time - just a random move is picked up.

Time mode Game
Normal:  30 minutes  (20 minutes for computer)
Blitz:    6 minutes   (4 minutes for computer)
A player who first runs out of time looses the game.

1st move: Human, Computer
Who starts the game. Starting the game means having black pieces for English/American and Pool checkers, and white pieces for other clones.  Note, that in E/A first move is a disadvantage.
My skill:  Dumb, Novice, Average, Good, Smart
5  levels of computer skill  in increasing strength.
Board view:  White, Human.
Affects a way the board is drawn:
WhiteWhite's 'home' is always located on the bottom - a usual way to draw diagrammes (for E/A as well !).
Human  The 'home' for a human player is located on the bottom - this is how you are probably used to play
Sound mode (optional): Off, Normal, Annoying
Even though your device supports sound, you might be not quite happy with it:
 
Off:This is probably what serious players prefer :=)
NormalSound at the end of a game only - my favourite, and therefore the default :=)
Annoying  Sound after each move, and at the end of a game. If your device is slow, or you play International Draughts against Smart, you might whish to use this mode in order to be awaken when the computer eventually moves :=)
Sound volume (optional) Low, Average , High
High is always full volume, average is half-full, low  is quarter-full.
Keypad ( Nokia Series 60): Standard, Nokia 3650,  Auto
There are currently two Series 60 models: Nokia 7650 with a common (rectangular) keypad, and Nokia 3650 with a circular keypad (as mentioned before). By default (Auto) the application will attempt to guess which device it is running on and will use the appropriate layout. This parameter allows forcing a particular layout, though you probably hardly ever need that.
Lights (optional):  Economy, Default, Always
A way to operate back lights:
 
Economy  Automatically turn back lights on for a human move, and off for a computer move. Recommended for high level computer skills (Good and Smart), otherwise you get your battery  flat even sooner than in default mode.
DefaultSystem default:  turn off in case of no key presses within a particular interval of time
AlwaysNever turn off 

Unfortunately  I couldn't get back light support with Series 60 devices, even though my Nokia 3650 reports as back light suppoort as available. Turning lights off looks really annoying, to turn back on press an unused key, like [0] on Nokia 7650, or [6] on Nokia 3650.

Operating a game

Move using keys

So, you started a game and are prepared to move. You can see a marked piece surrounded by a yellow rectangle, which we will refer to as the marker. You can move the marker with Left and Right keys, and only pieces that can currrently move are available for marking.

You can specify a move by one of the following ways:

By destination: takes longer but more obvious.

Mark a piece you want to move, and press OK, or Send.  This highlights a square where the piece is located, and  moves the marker to one of the places (destinations) where the selected piece can move.  Now use Left and Right keys to set a destination, and press OK to commit the move. In an ambiguous case (branching in middle of a capture) you need to repeat the procedure until the path is defined completely.
You don't need to select a destination, if only one destination is available for selected piece: in this case the move is performed straight after a piece is selected. Otherwise (unless you play Blitz) you can use CLEAR or [*]  key to cancel your selection. In case of branching, pressing CLEAR deselects last destination, you can change the destination, or continue pressing CLEAR until you can cancel the whole selection.
By direction: usually  (but not always) more efficient.
Mark to a piece you want to use, but this time instead of pressing OK, press one of the following keys:  
 
Standard Nokia 3650Action
[1] [1]Move (slide or capture)  forward-left
[3] [0]Move forward-right
[7] [3]Move backward-left
[9] [8]Move backward-right
In some cases (e.g. for a flying king) it is insufficient, so that you have to choose a destination from the specified direction, by moving a marker and pressing OK. In this case (unless you play Blitz) you can also use CLEAR or [*]  to cancel your selection.
The images above ( Standard  and Nokia 3650  layouts)  illustrate using keys  in  game.
 

Move using a stylus (touchscreen device).

By destination (two taps):

Tap a piece you want to use. If the piece can move, it will be highlighted. Then select a place where the piece gets by its move (destination).  In case of an ambiguity you need to specify intermediate destination(-s).

To cancel your selection (not in Blitz), tap selected piece again, or tap a different piece.

By direction  (dragging):
Touch a piece you want to use (don't lift the stylus)  and drag it to specified direction. If this is insufficient,  you have to choose (by tapping) a destination from the specified direction; in which case (unless you play Blitz) you can cancel selection by tapping selected piece again, or taping a different piece.

Other keys

To take back move use Down key, or equivalent. In case it's computer's turn to move, human's last move is taken back, otherwise two last moves (computer's and human's) are taken back. In both cases it will be human's turn to move. The application can store up to 124 last half-moves.

 To redo a taken back move press Up key, or equivalent.
N.B. Take back move is unavailable in Blitz game (in which case redo move simply doesn't make sense).

In case Sound mode is set to  Annoying,  you can  temporary disable sound  by pressing [#] key. Press [#] again to re-enable the sound. Tapping status bar on a touchscreen device has same effect.

Soft keys and menu.

While playing a game, you can bring up a menu by pressing LEFT SOFT KEY.

The menu includes following options:

Switch sides - the computer and human exchange colours. In case Board view is set to Human the board will be positioned accordingly.

Invert board - just invert the board, don't switch sides

Skill stronger - increase computer skill,  if possible  - this affects only current game, and does not change settings.  If  skill change is requested while computer is in the process of moving, the new skill will be effective starting from next move (even though status bar is affected immediately).
Skill weaker  - reduce computer skill, if possible - other comments to Skill stronger apply here as well.


RIGHT SOFT KEY  is used to quit current game after a confirmation.

Status bar

The status bar is located above playing board, and shows the following information (left to right):

Registration

Sorry, we live on this, and have to do something in order to encourage the registration ...

As you probably  noticed, an unregistered copy sometimes (2 out of 3 games in average) stops in the middle. The trick is that you never know (neither do I),  if a game is going to 'switch off', and at what move it will, because both parameters are random. The premature game termination is annoying but we believe is still better than reducing computer skill in the middle of game (practiced by a number of similar applications), because in our case you still have a chance to evaluate the computer skill at end-game.

In addition a registered copy shows Licensed to: <user name> at the bottom  of About page, while an unregistered copy just says UNLICENSED.

If you are not annoyed with this "feature" you might still wish (and of course are welcomed to) encourage our development for alternative operating systems which, as we believe, is the only way to ensure a fare competition between different software developers and platforms.
