Stair Rush is a hyper-casual running game where you sprint down a narrow track, collecting tiles to build stairs and climb past obstacles to reach the finish line. Your character moves automatically, so every decision you make counts. Grab enough tiles, stack them into stairs, and scale walls that would otherwise stop you cold. Miss too many tiles and you will not have enough height to clear the next barrier.

What keeps Stair Rush addictive is its simple one-tap control paired with genuinely tricky level design. Early stages ease you in, but later levels throw moving obstacles, tighter gaps, and steeper climbs at you fast. Timing your lane switches to grab tile clusters while avoiding blocks is the core skill loop, and nailing a clean run feels satisfying every time. Each level scores you based on how high you climb, so greedy tile collecting pays off if you can survive long enough to spend them.

Stair Rush is a perfect pick for fans of casual stair climbing games, tile collect runner games, and quick hyper-casual challenges you can finish in under two minutes. Whether you are looking for a free online running game with no download, a fun browser game to kill time, or a simple obstacle course game that tests your reflexes, Stair Rush delivers a clean, fast, and replayable experience straight in your browser.
