Space Y is a 3D anti-gravity endless runner game you can play instantly, with no install or extra payment. The setting is a massive cylindrical corridor slicing through space — and your bike doesn't ride the outside of that cylinder.
It rides the inside wall. You glide left and right along the curved surface with simple left and right taps, and most of the time that's all the input you need. The real mechanic is the lift pad: scattered along the track, each one inverts gravity the instant you roll over it.
One moment you're on the floor; the next you're on the ceiling, racing upside-down past the same obstacles from a completely new angle; then the next pad flips you back. That rhythm of floor-ceiling-floor-ceiling — and everything you have to dodge in between — is the core of Space Y's identity.
Obstacles start simply with gold coins and basic blocks, then layer in complexity through eight escalating stages: barriers that span the lane, gears that oscillate in sine-wave patterns, laser beams rotating in place, gate doors that only open when you hit the right switch, and trains bearing down at alarming speed.
The track itself accelerates as you go, so the tension builds continuously. You start with five lives, losing one per collision. Run out and the run ends — so gold collection isn't optional.
Spend it on four unlockable bikes with color customization and performance upgrades like rotation sensitivity, extra lives, and collection radius; unlock new stage environments too, each with a fresh visual backdrop.
Collect 50 coins in a single run to briefly activate a shield that absorbs one hit. Your score is your distance, and your personal best is saved for next time. There's no ceiling on how far you can go — except the one you're currently riding on. Hit the first lift pad and flip!
