Illuminations: Product Game

Product Game


The Product Game is a fun, interactive game that exercises your skill with factors and multiples.

Instructions

 
Object of the Game: To get four squares in a row—vertically, horizontally, or diagonally.
  1. To begin the game, Player 1 moves a marker to a number in the factor list of numbers 1-9 along the bottom of the game screen.
  2. Player 2 then moves the other marker to any number in the factor list (including the number marked by Player 1). The product of the two marked numbers is determined, and that product is colored red for Player 2.
  3. Player 1 moves either marker to another number, and the new product is colored blue for Player 1.
  4. Players take turns moving a marker, and each product is marked red or blue, depending on which player made the product. However, if a product is already colored, the player does not get a square for that turn.
  5. Play continues until one player wins, or until all squares have been colored.
