A must-have piece for every chess lover:

10 board themes, 9 piece sets and an infinite amount of generated chess positions. Generation rules exclude adjacent kings or pawns on promotion squares, however, they are still far from legal, since the king can find itself in double or even triple check, thus leading to absolutely absurd and hilarious positions!

The number of available editions is limited to 31, the age of Magnus Carlsen, who recently successfully defended his title and is the World Chess Champion for the 5th time in a row!
