Tunnel Rush drops you into a spinning neon tunnel that rushes past faster and faster while geometric obstacles close the gaps ahead. You have two controls — left and right — and the tunnel rotates around you, so the safe gap is rarely where your instincts say it is.
It's the same family as Slope: no story, no upgrades, one input, endless escalation. What sets it apart is the rotation, which makes reading the obstacles a genuinely different skill from other runners. The visuals do a lot of the work; the strobing colours are part of why runs feel faster than they are.
Same idea — an endless, accelerating, two-key reaction game — but Tunnel Rush puts you inside a rotating tunnel, so the obstacles arrive from angles as well as distances.
No. The tunnel generates endlessly and speeds up until you crash. Distance is the only score.
It runs in the browser with nothing to install, so it works on a school Chromebook wherever the site loads.
