If a square, prime, or odd is spun, then any number that fits those definitions is allowed. A player may use their turn to block an opponent. The first player to get five in a row either horizontally, vertically, or diagonally is the winner **(see fig. 7).**

Young children not familiar with the terminology of multiples, squares, and primes, can simply match a color or shape on the board to what they have spun. Each player individually spins, and then places a chip in a block which matches their spin. Only one chip may be placed on each block.
