The tunnel turns inside out.
2 500 m
That is how often it happens. The shell inverts, the rings tear apart, and the wall you were riding is suddenly above you. The physics never change – only your reading of the tube does.
Tilt. Flip.
Never stop.
Steer an endless neon tube by tilting your phone – it twists, speeds up, and turns inside out every 2 500 metres.

No buttons, no brakes –
just the tilt of your hand.
Tilt
CoreMotion turns the tilt of your device into rotation around the tube. Neutral is calibrated at the start of every run, so it works just as well lying down.
Sensitivity 0.50× – 2.00×

Native SceneKit with four quality tiers. The game watches real frame rate, thermal state and Low Power Mode, and steps down before you feel it.
Quality tiers L0 – L3
The music is not a file. It is written as you ride.
A synthesizer generates the score sample by sample. Layers stack up with your speed, boosts kick it, and the key transposes with every biome. Prefer your own? Pick a playlist or album from your Apple Music library instead.

Nine ways to
lose the tube.
Each mode rewrites the steering physics, the track generator and the look of the tunnel. Start with the tutorial – Classic opens the moment you finish it, the rest unlock as you collect shards.
Classic
The original endless run. No twists, no tricks.
Race
High-speed experience. Push your limits.
Wind
The wind is always blowing. Fight the force.
Drift
Low friction, high skill. Master the drift on ice.
Magnet
Opposites attract. Navigate chaos and polarity.
Crystal
Smash the violet to go faster. Never touch the black.
Maze
Twists, turns and no room for mistakes.
Gravity
Four walls, four wells. Commit to the leap.
Ember
The hive is burning. Don't stand still.
Race a friend.
First crash loses.
Invite someone or find a quick match through Game Center. The mode is drawn from whatever you both have unlocked, so you never know which tube you’ll get until the countdown ends.
Same track, same seed. First to crash loses – crash within a quarter second of each other and the longer run wins instead.
Your opponent rides the same tube as a ghost ahead or behind you, with the gap in metres live in the HUD.
Lost? Ask for a rematch – new track, new mode, no searching for a new opponent. Both players confirm before it starts.
See how far you get.
Distance is the only score. The tube does the rest.
