One line. One thumb. Infinite gaps.
A red line falls, walls rush up, and every wall has a gap. Swipe one finger to steer, thread the opening, and keep going as long as your nerve holds. Simple to pick up — impossible to put down.
Endless & escalating. Every level tightens the gaps and mixes up the walls — drifting, tilting, pulsing — so no two runs feel the same.
Six hand-crafted worlds. Blaze through fire, drift through floaty underwater currents, race a glowing synthwave grid, survive a spotlight blackout, and sail an aurora-lit cosmos. Each theme looks stunning and plays differently.
Risk it for the combo. Shave the edge of a gap for a near-miss and watch your streak — and your line — ignite from red to gold.
Power up. Grab Ghost, Slow-mo, Magnet, ×2 Score, Shield, Bomb and more. Stock up Freeze charges and double-tap to freeze the world when things get tight.
Beat your best. Track your high score and climb the online leaderboards with Google Play Games and Apple Game Center.
Made for one hand. Sub-second restarts, buttery controls, and a clean minimalist look built for "just one more run."
Free to play. No account needed. How far can you take the line?
