The game board is just like that of a checkers/chess board. Each 4x4 corner is owned by one of the players. The player can play the cards in they're hand to place tokens onto the game board, but can only place tokens in their area. once on the game board each token can move once a turn, moving into an occupied space will make each token fight. The beginning of each game, each player can pick were in their area they want to place a castle. The goal being to attack the other players castles until they get destroyed.
Like everything it still isn't finished, and is missing some fundamental mechanics for attacking and using the abilities on cards. So you basically just place tokens and move them around till you're out of resources.
Till next time ... uh.. I forget.
