Muscle Rush 3D

Muscle Rush 3D is a runner where the route is a set of choices about strength. Gates along the track multiply what you have, protein adds to it and junk food takes it away, so the fastest line is not always the strongest one. Gym stations break up the running with weight lifting, and rivals have to be fought rather than avoided. The finish is a high striker: you swing a hammer at the puck and the height it reaches decides the reward, which turns the whole run into a single measured outcome. Outfits and customisation are unlocked along the way, strength can be upgraded, diamonds are collected, and there are a hundred levels across five worlds. Steering is a drag or the arrow keys, and a click or the space bar punches and swings the hammer.

Key mechanics

• Gates multiply strength; protein adds, junk food subtracts
• The high striker at the finish decides the reward
