An elimination game in which players need to quickly respond to commands.
Some divider is chosen by the leader. This can be a string on the ground, the change between sidewalk and grass, or the imaginary line that is drawn between two chairs set up.
The leader explains that one side of the line is the "river" and the other side of the line is the "bank". It is essential to be at the right spot at the right time (can make up story about scorpions on the bank at some times and piranhas in the river at others).
Players then line up, shoulder-to-shoulder, on the bank. The facilitator then shouts out one of two commands - "river" or "bank".
If they facilitator calls "river", players must jump forward across the boundary line into the "river". If the facilitator calls "bank", players must jump back to the "bank". The facilitator can call bank or river multiple times in a row.
If a player jumps when they are not suppose to (or fails to jump in an adequate amount of time), they are eliminated from the game. (it can be helpful for the leader to have them come help judge who should be out so as to keep them engaged.)
