An educational game system wherein a random selector of mathematical problems is used in playing various popular board games, simultaneously providing drill in the multiplication tables. Players must determine missing answer numbers which then dictate game piece movements. Appropriately formulated problem sets, together with dice doubles indicia, permit the random selector device to substitute for dice, spinners, and other random selection means normally used in these games. Changeable problem sets provide drill in particular multiplication tables. Usage procedure facilitates table memorization. The problems each have a missing number in which the majority are not full two digit numbers but the first or second digit of the product or one of the factors. The average value of the missing numbers for a set being less than ten. Five embodiments are disclosed, employing different random selection devices.
