Let's start with an overview of the game. It is composed of of a base which is accompanied by various blocks. The basic game proceeds as follows: one player places any block in any orientation on the base. Another player chooses a block and places it anywhere on the base or on the previously placed block. The play alternates between players and gets progressively more difficult. You lose when the block you are placing either falls or causes any other blocks to fall off the base. See the design considerations section at the end of this plan for more detailed rules and alternatives.
