Hear the sound, then quickly slam the picture it matches - this is a crazy but fun game for two to four players (one slapstick per player). It is great for hand to eye coordination and for listening skills too.
Each game requires the players to wait and listen for one of the unique sounds coming from the "sound randomizer". Then you have to slam your slapstick to grab one of the fifty two cards that matches the sound - from broken glass to a hooting owl. You have to be fast because everybody else is also trying to grab the correct cards, and the "sound randomizer" plays new sounds at short intervals. The player with the most cards at the end of the round is declared the winner.
Slam the cards
Slammers ($21.90), by UGames Australia, is a fast and exciting game for the whole family and comes highly recommended by mine.
