Math Runner is an online running game that mixes quick reflexes with basic math challenges. Players guide a character through a constantly moving course while solving math problems that appear along the way. Each problem has multiple answer paths, and only the correct one keeps you moving forward—pick the wrong one, and the run ends. Along the route, players can collect coins and power-ups to increase their score or unlock extra features. The pace of the game pushes you to think fast, testing both mental math skills and reaction time. The more accurate and faster you are, the higher your score climbs. You can play Math Runner instantly on kbhgames.com for free, directly in your browser, with no installation needed. It’s built for quick sessions but still offers enough challenge to keep players engaged over multiple runs.
