The aim of the game is to rid your hand of all cards, or to stack all 9 blocks - which is highly unlikely. Play a card from your initial hand of seven, and place a block on the stack, using only one hand. The cards specify size and/or colour of the block to be played. The stack may not be steadied. If the stack collapses, take 3 cards as penalty, and start a new stack. The two action cards are pass and reverse direction. —user summary
