A cube that runs forever through a spiked corridor. Flip gravity to survive.
Gravity Flip runs completely inside your browser — nothing to install, no account, no download. The board is drawn on a 960×540 canvas that letterboxes itself to any screen, so it plays the same on a laptop, a Chromebook or a phone in landscape.
How this version plays
The whole run is built around one idea: Press SPACE or tap to flip gravity / Spikes sit on the floor and the ceiling. We tuned the speed curve so the first thirty seconds feel gentle, and by the second minute you are genuinely busy.
Scoring
Your score is pure distance — one point per 10 metres. There are no pickups, so a clean 1200 m run is worth 120 and nothing more.
Why we kept it small
One-button games age well. Flipping gravity instead of jumping means the ceiling is playable space, and the patterns read like a rhythm line rather than a wall of hazards.
How to play
- Press SPACE or tap to flip gravity
- Spikes sit on the floor and the ceiling
- Distance is your score u2014 speed never drops
Controls
SPACE, click or tap flips gravity between the floor and the ceiling.
FAQ
Is there a double flip?
No u2014 one flip per press, and gravity pulls you all the way to the surface you chose.
How fast does it get?
Speed grows about 17 px/s every second, so after a minute you are travelling roughly twice the starting pace.
Why did I lose a life on a clear corridor?
Spikes are 30 pixels deep u2014 if the cube clipped the very tip, the hit registers even when it looks like a near miss.
