A game device has a flat, circular bottom wall with a plurality of ball-receiving wells formed in it and a transparent dome-shaped cover that captures a plurality of balls within the device. Some of the wells have a number shape, and each of those wells are color coded. The game is played by inverting the device and restoring it to its upright position or by shaking it until all of the balls have entered into the wells. The number of balls within a well are counted and multiplied by the number of the well into which they have fallen to arrive at a total for that well. Depending upon the color of the well, the total is either added to or subtracted from an earlier total and the process is repeated to arrive at an arithmetic sum. A pair of wells are also formed in the shape of a multiply sign and a divide sign and the arithmetic sum is multiplied by the number of balls in the multiply sign-shaped well and that number is divided by the number of balls in the divide sign-shaped well. A uniquely marked ball is then used to calculate a percentage of the previous number and that number is added to or subtracted from the previous number, depending upon which well the uniquely marked ball came to rest. In additional embodiments, the balls are counted by ball sensors and the arithmetical calculations are performed by a microprocessor that drives a display device that provides a read out of the correct answer.
