How observative you are ?
For how long can you keep concentration ?
This game is extremely simple and very addictive as well: watch the
lights flashing and all you need is to notice the colour (position on a
monochrome screen) of the last flashing light. Since the number of
flashes is random, you have to be concentrated all the time while the
You can play with the computer, or invite your friend for a
three-player game (two humans and the computer). The application allows
to customize speed and some other parameters. It stores settings and
The application used to be known as T-Lights. The name was
changed to avoid confusion with a PC application having same name, but
nothing else in common with the current one.

Single human (1H) and two human (2H)
The game allows one or two human players, later refereed as single
human(1H) and two human(2H) modes..
A human player scores 1 point for each correct choice. The
computer never bids, but scores 1 point if none of players succeeded.
If same bid is allowed for 2H mode (see Rules
), both human players can succeed, in which case each scores 0.5
Match and match
A match consists of a nominated number of games. The number of games in
a match is specified in Rules . A match ends
prematurely if the winner is established (i.e. others can't catch up).
In a two-human mode, computer score is ignored if Computer w/2H
is disabled in Rules In a two-human mode the
order of bid changes with each game, and between matches as long as
player names remain unchanged.
The application keeps total score for 1H matches: matches won by
human and computer, number of draws. Total score is shown before
starting a match in single-human mode.
Main screen and menu
The application starts with main screen, where you can select different
menu options and start a match.
In a 1H mode you can see total score which is stored in the data
base and updated after each completed match:
You can clear total score (set all values
to 0) by selecting Reset Score from the options menu
(works for a registered copy).
To switch to 2H mode, select Two Humans from the
options(bottom) menu. In a 2H mode you will see either
< Player-1 name>
< Player-2 name>
depending on whether computer
participates or does not participate as a full-featured player (see
Rules for details).
< Player-1 name>
To enter player names, select Who Plays menu option. For
reverting to 1H mode, select One Human.
To start the match press FIRE button or  phone key. FIRE is
often associated with Send button
(a green button with the picture of handset off-hook), but some devices
have a special button for FIRE, like joystick press (Nokia 7650), or
centre of arrow pad (Nokia 3650). Symbian OS release uses joystick/OK
press as FIRE, while Send is used
to bring up Rules.
Here is the summary of menu options for the main screen:
Two Humans - switch to the
Reset Score - set all total score values to 0
One Human - switch to the single-human mode
Who Plays - set human player names
Start - start match (FIRE or  has same
Rules - customize game rules (see Rules)
Help - hints (where available)
About - general information about T-Light
Exit - quit the application
Bidding starts as soon as the lights stop flashing.
Current bid is indicated with a flashing arrow. Use UP and DOWN,
to place the arrow agains the light position you wish to select, and
press FIRE or 5 button to accept the bid. After bidding is complete the
light is revealed.
In 2H mode the order of bid changes from game to game, and human
players are interchanged before starting a new match.
To activate Rules screen, select Rules menu option
from the main screen. For a unregistered copy this works as a demo: you
can modify the values, but can't activate them. Therefore the default
values are the only ones available for unregistered users. Default
values are shown in bold.
Use UP and DOWN, or  and  keys to select an option you
wish to modify. Then use LEFT and RIGHT, or  and  keys to modify
the value. You can also use [*] and [#] to reduce/increase value by 10
(this is convenient for big ranges, like Flashes Max/Min)
Select Accept menu item to activate new values (registered
version only), or Cancel to discard the changes.
You can retrieve the default values at any time by pressing 
key (Send key for Symbian OS
release) , or selecting Default menu item if available (those won't be
active untill Accept is selected) .
The following game options can be set up.
||No Way, or Alow
|Computer w/2H: (*)
||No or Yes
||from 4 to 20
||Slowest, Slow, Average, Fast, Fastest
||from 5 to 500, default 30
||from 5 to 500, default 220
||No or Yes
||from 0 to 9, default 2
Same bid: affects 2H mode only. If same bid is not allowed,
second bidder can't replicate a choice made by the first bidder, thus
each game will have a winner (that can be a computer in case both
Computer w/2H: Whether the computer is considered as a
full-featured player. If "No", the computer score does not affect the
match winner, in particular the computer cannot win a match, and a
match cannot end prematurely, unless a human winner is established.
Games/match: maximum number of games per match. A match
finishes earlier, if no one can catch up with the leader in the
Speed: affects the duration of each flash. Be aware that the
slower is speed, the longer is the game, which requiers more patience.
You can work it out by reducing Max flashes, if available.
Min flashes: and Max flashes - the actual number of
flashes is a random value between Min.flashes and
Max.flashes. In particular, if Min.flashes = Max.flashes,
the number of flashed is predefined.
Extend last: if enabled, the last flash will appear for a
slightly longer time then others.
Sound volume: a number from 0 to 9: 0 - disable sound, 1
-soft sound, ... 9 - loud sound.
This form allows to set up player names in 2H mode. This does not
affect names in single-human mode, so that the form is available only
if you are about to start a match in 2H mode.
You can set names to default by pressing  key (
Send key for Symbian OS release) , or selecting
Default menu item (whichever is available).
While selecting Accept to activate new names, you reset
the order of bid, so that first player will be the first bidder in the
Back lights keep turning
Some devices use a power saving feature where back lights turn off
after no key was pressed in a particular period (usually 15 seconds).
Nokia and Siemens releases of T-LightZ by default will attempt (where
possible) keeping back lights on with default intensity 50% for Nokia.
You can disable back light control for a Siemens
device, by adding / editing the following parameter in JAD file:
For a Nokia J2ME device you can use the
following line in JAD to control back light intensity:
Where xx is either "No", or a number from 0 to
100. Value "No" or 0 disable back light control.
Nokia Series 60 devices usually do not allow controlling back
lights with J2ME. Use Symbian OS version where back light control is
This should be event simpler than playing the game :=)
The advantages of a registered copy:
The application can be purchased from one of the following sites:
- No Registration form at start
- Ability to reset total score at any time
- Fully functional Rules
- Licensed to <name> on the Main Screen
Please, specify the user name - this name will appear
on the bottom of Main screen in the place
where you currently see UNREGISTERED.
You will receive the code that should be enetered along with the
user name in the Registration form. Once you select "Register" and the
code is validated, the application will quit. Restart the application
