What are the chat games? How do I start playing?
There are plenty of GasGames on homokaasu.org. You can invoke four of them through the TKEP chat. Two of games are called Acronymania and Hanggnome; these games are played on the chat client. In order to begin one of these games, you must enter the phrase "!play <game's name>", e.g. "!play acronymania". You can also join a currently played game by typing "!join".
The other games, SpasticChess and Character Disorder, are one-on-one games, only viewable by the players (no "kibitzers" there). To play those, you should write "/play <game's name> <opponent's name>". This will result in a line similar to this:

showing on your screen, and in a similar line appearing on your opponent's.

Both opponents must click that line before the game can be started.

How do I play Acronymania?
Once the round begins, you should see a series of four or five letters on your screen. To play, you should create a phrase, with each letter being the first letter of each word. For example, if given the series IUOPG, you can create the phrase "I use orange porcelain glasses". You must submit your phrase by putting an exclamation mark before he phrase, e.g. type "!I use orange porcelain glasses". After 72 seconds, no more phrases are accepted, and those who have already submitted a phrase are allowed to vote on the best phrase submitted. Of course, one cannot vote one's own phrase. Scores are kept; however, there should be at least three players, and players who failed to vote will not have their score saved.

How do I play Hanggnome?
The team is given one minute to guess a phrase. In the beginning of each round, you will see the phrase in the black box, with asterisks instead of letters; punctuation will be shown though (e.g. "***** ** *****?"). At this point, the team must guess the phrase, letter by letter, similar to the well-known hangman game. You can guess one letter every three seconds; to guess a letter, put an exclamation mark before. For instance, to guess the letter "w", type "!w" or "!W". This will result in revealing all the W's; to take the same example, you will see "W**** ** W****?". Each correct guess will award you one point (for example, guessing "w" here would award you two points). A wrong guess would cost you either one or two points, depends on whether you guessed a vowel or a consonant. Notice that the group is not allowed to make more than eight mistakes. You could also try guessing the whole phrase, by, shocking enough, putting an exclamation mark in front of it, e.g. "!Which is Witch?". Guessing the whole phrase correctly would add 10 points to your stock (plus 2 points for any hidden letter), however, it is advisable to guess a few letters before going to the phrase. For instance, let's say you have guessed the letters "h", "e", "i" and "l"; now, you see "Whe*e i* W*ll*?", and you have greater odds to guess the phrase, which is, by the way, "Where is Wally?". All phrases are in English.
The game will stop when the time runs out, too many wrong guesses were made or the phrase was guessed right. Scores are kept only if three users or more participated in the game; negative scores aren't kept.

How do I play SpasticChess?
First of all, you should start the game, as described earlier. Then, rules ought to be decided.
SpasticChess is similar to Chess in the way pieces move (apart from castling, en passant and pawn promoting, which don't exist on the former). Two of its properties make it special: capturing the opponent's king is made by making it lose hitpoints, rather than mating, and moves aren't taken by turns (although this can be changed when starting a new game). Basically, one can move any piece whenever one feels like it. There are, however, two important rules which limit that: no piece is allowed to move twice in a row (e.g. if one moves one's queen, one has to move another piece before one is able to move one's queen again), and the king cannot move to a square where it'd be checked. Checkmating, therefore, significantly helps winning the game.
Both kings start the game with certain (and similar) amount of hitpoints, which is chosen when starting a new game. Those are slowly deducted when the king is checked, until they reach zero. Then, the game ends.

How do I play Character Disorder?
Start the game as previously described.
The goal of Character Disorder (or "Chardis") is to destroy blocks which fall off the sky (no, not really). Somewhat like Tetris, except that you need to do more on Chardis in order to make the blocks vanish, and that the blocks are wholely different - they have different colours, and letters are written on them. The blocks fall in five different columns, each marked with a certain colour, which appears on its base.
Blocks can be moved horizontally, using a "grey loopy thing" called "Kontroller". When the Kontroller lies on line n, and the right/left arrow key is pressed, the letters on line n will scroll to the respective direction. To destroy a block, bring it exactly above the base which has the same colour, and press the key of the appropriate letter (the letter which appears on the block).
If a block is destroyed, any touching block which is similar by colour or letter will disappear as well. That way, chain reactions can be built. Generally, one must create plenty of chain reactions, the larger the better, in order to achieve high scores on Chardis.
On the buttom of the screen you should see two numbers; the bigger is thy score, and the smaller is the quantity of blocks which are about to be added.
