Scrabble Slam. Every letter counts. The Race Is on. Scrabble Slam is the best-selling, fast-paced and easy to play card game version of Scrabble. Start with any four-letter word on the table, like cake, yell out Ready, Set, Slam. and the race is on. Quickly change the existing word, one letter card at a time, to create a new word. For example, Cake becomes Bake which is turned into Bike then switched to Like and so on. The first player to play out all their cards wins. Also includes rules for an all-new Scrabble Slam game, Double Scrabble Slam, where players start with two words.
