Rainbow Reef: Color Dive

You're a glowing fish in the deep.

Tap to rise and push forward. Keep tapping and you climb. Let go and you sink.

Swim through a vent and it paints your light a new colour. The coral wall ahead is built from four blocks, and only the one matching your light will let you through. Read it early, line up, slip past. Get it wrong and the run ends there.

You're not down here alone. A hunter patrols the open water. Jellyfish drift across the surface in blooms. An octopus clings to the ceiling and sweeps its arms down without warning — so the roof you'd been safely skimming along stops being safe. Touch any of them and you're finished, unless you grabbed a shield on the way past.

Let go and you sink, and the whole reef slows to a stop with you. Rest on the sand as long as you like, then tap to pick up exactly where you stopped. Useful for lining up a wall you can't quite read — or for putting the phone down mid-run.

No connection needed. Plane, tunnel, basement, same game.

Every colour carries its own shape too, so you're never squinting at two similar blues while something closes in.

More fish to swim as, more oceans to swim in. All optional — the whole game plays free.

One thumb. No account. No timers. No wifi.
