The polarized adhesion material is preferably hook and loop fastener material. The game rules provide that playing pieces are deposited only where adhesion is strong, and may be stacked in accordance with this rule. Other rules are applied to define and differentiate game play. The game board is optionally reconfigurable, and may also have integrated electronics. The game board may include a foldable housing to contain the playing pieces when not in use.
