About Obby: Muscle Race — High-Energy Runner with Math Gates and Boss Battles
Obby: Muscle Race is a fast-paced 3D runner where the gates you steer through physically transform your character. Pick the right math operators and your body grows from skinny to stacked; pick the wrong ones and you shrink back down before the finish line. Short levels keep the pace relentless, and a boss battle arena waits at the end of every run.
Between runs, coins fund permanent upgrades to attack, HP, and coin bonuses, while a Lucky Wheel hands out free prizes and a skin collection lets you change up your look. Boosters — shield, level boost, and double-power — can be popped before a run to give yourself a head start.
How to Play Obby: Muscle Race
Start from the main menu and steer your runner through a gauntlet of math gates. Addition and multiplication gates grow your muscles; subtraction and division gates shrink them. Along the track, power-ups are there to collect and obstacles must be dodged to stay strong heading into the final stretch.
At the finish line, the run turns into a boss battle: punch as fast as possible before the opponent lands their hits. A win earns coins, and watching a short video multiplies that reward further.
Coins go toward upgrading attack, HP, and coin bonus, unlocking new skins, and spinning the Lucky Wheel for free prizes. Upgrades carry into every subsequent fight, so a stronger build means a bigger body and a better shot at the knockout.
