Slapagories

A spin-off of Scattergories. Players sit around a small round board with the words "I know" on it. There are two decks of round cards in special holders, one that has a single letter on each card, and one that has a category. The decks are placed FACE UP.

The first player to say "I know", and slap the board, gets to take either the letter or the category card, which thus IMMEDIATELY changes the letter or the category - and starts the next "turn". Conflicts are resolved via majority vote.

When either deck runs out, the game is over. Whomever has the most cards wins.
