Grabitz is a commercial version of the traditional card game Spoons.
Players collect cards trying to spell "Grab" using either cards all from one color or cards with only a single letter each but of any color. Once a player has accomplished this, they grab one of the hands in the middle of the table. Everyone else then grabs one too as quickly as possible. The player left without a hand gets marks scored against him.
Once a player has enough marks to spell "Grabitz", he/she is eliminated. The last one standing wins.
