Treasure Mathstorm is an educational computer game intended to teach children mathematical problem solving. It is the unofficial sequel to Treasure Mountain!.
The Master of Mischief has used a weather machine to freeze Treasure Mountain. To thaw it, the player must collect sufficient treasures using snowballs.
The mountain, as in Treasure Mountain!, is divided into three levels. Unlike the previous game, to advance to the next level, the player has to complete various challenges- the first relating to telling time, the second to inequalities and basic algebra, and the final simple computation.
Snowbullies, evil flying snowballs, serve as the main antagonists.
Once the player reaches the mountain's peak, they find themselves in a room with The Master of Mischief sitting in a chair inside. The player obtains a treasure from an elf and then jumps out of the window. The player then puts the treasure on a shelf inside the starting cave and can then go up the mountain again until the treasure chest is full.
