Rainbow Obby unblocked packs a whole collection of blocky parkour maps behind one rainbow-covered menu. Every card leads to a different course for the same yellow-headed hero: classic jumping over floating blocks, an ASMR run across giant keyboard keys, a brand-new Tower Obby, a sticky Slime Tower with three hearts, troll levels full of fake floors, and vehicle routes where you cycle, drive, ride a cart, fly a plane or paddle a boat down a river. A progress bar shows how far you are from the finish flag, checkpoints save your spot, and coins unlock fun extras like the novelty rides in the Cart Obby store. Falling only sends you back to the last flag, so it is easy to keep trying. Players who love Fun Obby, Stickman Climb 3D or Eggy Car should give it a go.
Move with W, A, S and D, press Space to jump and turn the camera with the mouse. On bikes, cars, carts, planes and boats the same keys steer, so use small taps instead of holding a direction. Press R to return to your last checkpoint, M to open the shop and Esc for the menu. If you fall, choose Respawn to try again from the last flag or Skip to move past a tough part. Start with the Classic course to learn the jumps, then explore the other twelve modes whenever you want a change of scenery.
