Muscle Up Master

Muscle Up Master mixes idle bodybuilding with martial arts progression. Weak rookies appear on the board, and matching two of the same creates a stronger fighter. Each upgrade brings the next form, building a long fusion chain from scrawny beginner to gym champion. Once a fighter hits the required level, the boxing-glove button lights up. Then it's time to step into the alley behind the gym and brawl for cash. Win those fights to speed up your climb.

How to play?

New athletes appear in the grid automatically. Drag identical fighters together to merge them into a higher-tier character. When one reaches the battle requirement, tap the glove button to switch to the fight screen. There, tap fast to throw punches and overpower your opponent. Spend your earnings on faster athlete spawns, a higher starting level, and more passive income.
