Ovanligt matte-spel med RPG-inslag.

"The Dark Lord Randamn has invaded Calculator Island, throwing the calm land into utter chaos. Only through the efforts of studious young heroes can order be restored. In an interesting attempt to make a study-aid game, someone thought it would be a good idea to have RPG battles hinge on one's ability to do sums. Heroes must push their higher math skills to the limit in order to save Calculator Island from the Dark Lord Randamn in this quirky study-aide RPG. "
