From the publisher's web site:'Slammer is fast, exciting and full of fun! Listen to the sound coming from the randomizer and try to grab a pair of cards matching with that sound - with both sides of your slapstick. You have to be quicker and more sharp-eyed than the other players, because everybody is trying to grab the correct pair of cards and the randomizer keeps on playing new sounds at short intervals. The player who collects the most pairs during three rounds of slamming and grabbing wins the game!'From the box cover:'Fast, fun and full of action'and'Fun and frantic family game' - BoardGameGeek
