* Pictionary: You draw up and down, but it's not Scrabble.
* Jenga: You pull blocks up and down, but it's not Scrabble.
* Up and Down: This is a simple number guessing game. You guess a number, and the other player tells you if it's higher or lower. Not Scrabble!
Let me know if you have any other clues, and I can try to narrow it down!
