A lottery game is a WarLight game that is won by random chance rather than skill. These are used by players who don't want to play a real game.
There are a few special rules concerning lottery games that players must follow:
- If you're creating a lottery game, please be sure that the word "lottery" is somewhere in the game or tournament name. This allows players who don't want to see lottery games to hide it with the check-box on the Open Games and Open Tournaments pages.
- When creating a lottery game, it must be won by random chance. You cannot give yourself, or any one player, an advantage. All players must have the same chance at winning.
- It should be reasonably clear how to win. If the winning strategy is well hidden, you should not explain it in the game description.
