Prod writing

Before the game, the contestant has to blindly pick a coloured ball out of a box. The colour of ball they pick represents the guard they'll be fighting against. 

In the middle of a pool are two small, round platforms, a short distance from each other. The contestant stands on one of these platforms while the chosen guard stands on the other. Each of them has a long lance with a big rounded end on. 

On the whistle, the contestant and guard have to push and prod each other with their lances, trying to knock each other off the platforms. If the contestant manages to push the guard into the water they win the game; but if the guard pushes them off first, the contestant has lost.
