ABSTRACT:
A multiplication-division game containing chips (16) representing multiplication products and playing cards (14) representing multiplier-multiplicand combinations which equal the products of said chips. Each player has a placemat (10) for holding dealt and drawn cards. The chips are arranged in three piles (16) and the players take turns trying to capture the chips by combining pairs of cards whose products equal those of any one of the three top chips. The player who captures the most chips is declared winner; successful multiplier-multiplication cards being discarded. The players alternate play; with each turn a player draws a new card from a stack and matches pairs of cards against the chips until such player can no longer capture any more chips.
