Take a normal Jenga game. On one side of each piece, write a dare. e.g. drink five sips of black coffee; sing “I’m a little tea pot” with the hand motions; tie both shoes together and run thirty feet; with your eyes closed, draw a house with a picket fence; etc. Build the tower with the dares facing downward. As they chose a piece, they can either perform the dare for ten points, or dare someone else. If the challenged performs the dare, they get ten points. If they cannot perform it, or refuse, the challenger receives five points. If you are the one to topple the tower, then you lose fifty points.
