Easy
Arithmetic and direct relationships, with a clear path from story details to expression.
Hemispheres
Both sides of the problem matter.
Ridiculous stories. Real math. A story-driven mathematics game that rewards the reasoning behind an answer, not only the final number.
Build the answer, not just the result.
Identify the relevant information, translate the relationships into an expression, and use the integrated calculator to construct a solution. Hemispheres can evaluate whether the expression is valid, whether the reasoning is structurally sound, and whether the result is accurate.
Correct reasoning can earn partial credit even when the final answer misses. Guided multi-step problems, directional hints, structural hints, equation support, and explanations help players understand what worked and what did not.
