Mental note: To extend good mood, wear them on when going out from home.
The chess that Xul made up has 13×13 boxes (and not 8×8 as the conventional one), that represent stars and constellations. Each player has 30 pieces instead of 16, and one of them can be used by any of them indistinctly. The game starts with an empty chessboard and the pieces aren’t eaten, but catched and become their own. But, what we like the most about it is that no one loses and all win: without any doubt, it is the game we would all love to play!
