It’s the Scrabble Slam Card Game! You’re gonna love this fun twist on America’s favorite word game — Scrabble! Impress all your friends with your vast vocabulary and extensive knowledge of the English language!

In this fast-paced card game based on Scrabble, each player is dealt a hand of two-sided cards: each one has a different letter on each side, and a pair of letters in the corners that note which letters are on each face. Players create a four-letter word to start the game, then replace one letter at a time with cards from their hands. The first player to get rid of all their cards wins.
