Do you know of any good indoor recess games?

I work as a recess monitor at an elementary school. Now that winter is here, we can rarely go outside. I need some games that I can do with the kids. We have all kinds of puzzles, coloring books, word finds, board games, and cards--that's not what I'm looking for. They get bored easily, and I need games we can play like Hangman or Heads Up Seven Up. (Not those two, though--I know how to play those!) Some of my cles do better with a group game than they do playing with board games and coloring. Thanks for helping me!
