Knockout Checkers Chamber

In a magical parallel world, a decent alternative to wars and duels was invented: combat checkers! 
This game suits everyone: the rules are understandable even to the warchiefs of the barbarians from the Northern mountains, and its profound philosophy is highly appraised by fastidious strategists of the imperial court. 
The dynamism and aggressiveness of this game is harmoniously combined with the fact that competitions are held in the cozy, homelike chambers of the imperial Minister of Magic.
