Bounce

Bounce is played on two identical 6x6 grids. The rows and columns are labeled with letters and numbers, and each space contains a letter or number. Each player uses one of the grids. On a turn a player marks an empty space in their grid, and the letter or number in that space determines the row or column where their opponent must play. That play will determine where the first player must play, and so on. The winner is the first player to mark four adjacent spaces in a line.
