A kind of checkerboard is shown containing 25 playing cards. On the cards you place two different colored chips/checkers, say red and blue. One spectator selects a red chip and another a blue chip and all the other chips are eliminated from the board. Each spectator is asked to select a number and to move his chip at random around the board according to the number selected. Once this has been done, ask the audience which chip should win. Assuming they say red, a spectator opens a prediction that was on view at all times and this tells how to proceed with the rest of the game, detailing the moves for the red to win, including the name of the card that allows the victory! Very easy to do. Complete with board and chips.
