A small runner turns into a towering brawler over the course of each track in Giant Rush. You dash forward through a course full of obstacles and pick up colored figures along the way, and every one you absorb makes your giant bigger and stronger.
The payoff waits at the finish line, where a boss is ready for a fight. How that fight goes depends on the run before it: the track throws hazards at you to dodge, and every figure you skip is size you will not have when the battle starts. So each run is really about steering toward figures while timing your moves around anything dangerous.
Between runs you can upgrade your giant’s abilities, and progress unlocks new challenges. Upgrading before a tougher track is usually the safer order. Another quick runner built on timing is Geometry Lite, and it plays on desktop or phone just like this one.
