About this release.

Originally the game was released for Palm  handheld computers and available from  Xr0w PalmOS site.

This manual refers a J2ME (Java 2 Micro Edition) release designed mainly for J2ME - compatible mobile phones (Motorola i85 series, Nokia 6310, Siemens SL), and can be also be used on any  J2ME-compatible handheld.

 

How to Play

Objective'

One plays X, another Y.  A player who succeeds in making a horizontal, vertical, or diagonal row of consecutive pieces wins. The game ends with a draw, if the board is nearly full, so that neither of players can complete a row.

The application keeps complete move history for the current game, therefor you can take back unlimited number of moves and replay previously taken back moves, however once you've made a move you can't replay.

The application saves and restores the last game. It  provides a range of options to suit your preferences.

Play Options.

To invoke Play Options screen, select Play Options menu item.

The following play options can be set:

Players:  Computer vs Human or vise versa.  You can switch sides, so that computer will move for you, while you will move for the computer by pressing  either 0 or  5 key, or by choosing Swap   menu item.

Skill:  The skill of your computer opponent.: Novice , Average(default) or Bright .  During the game,  the computer skill is displayed by its initial letter ('N', 'A' or 'B') on the status bar. By pressing * key,   or selecting Change Skill  menu item, you can change computer player skill   from Novice to Average,  from Average to Bright, or from Bright back to Novice.

Toggle Auto-feed:  If auto-feed is ON (default), take back and replay actions apply to both players. In case auto-feed is OFF, only single ply is taken back each time, that, as a matter of fact, allows you forcing a particular move for the computer.  There could be other reasons why you may dislike auto-feed.
