Two 10-Sided Dice and Problems Up to 20
Each turn starts with two 10-sided number dice, so the numbers go much higher than a pair of ordinary six-sided dice allow. Together with the operation die they create addition and subtraction problems up to 20, the range Learning Resources designed the game around and the span of number facts children work on in their first years of school. Because the numbers change every roll, a child keeps meeting different facts instead of rehearsing the same few, which is how quick mental math builds. Parents report exactly that kind of progress. One who played every day for two weeks saw his son go from needing candies as counters to solving most problems on his fingers or in his head. The bigger numbers also bring a cost, covered below: a big lucky roll moves one player much further than a small one, so the gap between players can grow quickly.
