Monkey Spank! is a simple adult themed pattern recognition game in which players try to find an image shown on two cards.
Each card in Monkey Spank! features eight different symbols, with the symbols varying in size from one card to the next. Any two cards have exactly one symbol in common. For the basic Monkey Spank! game, one card is placed face up in the center of the table and players are dealt the remaining cards face down. Players simultaneously reveal the top card from their decks and try to find the symbol in common with their card and the center card. Which ever player is first to yell out their matching symbol (for example, "ball gag!") places their card as the new center card. That player then reveals the next card in their deck and all players repeat the process. The first player that runs out of cards in their deck is the winner.
