One touch · Pure flow

SineOn

Ride the wave. Chase the score.

Hold to ride the wave forward. Release and the wave keeps rolling — sweep in place, pick your moment, re-engage. Graze for bonus, never idle too long. A neon arcade machine in your pocket.

One input.
The whole game.

No buttons, no menus mid-run. The skill is rhythm and timing — not complexity. Press and hold the panel to feel it.

LIVE · DEMO PRESS & HOLD ↓
01

Press to engage

Hold and the ship surges forward along a fixed sine wave, carving a smooth undulating line through the field.

02

Release to wait

Let go and forward progress stops — but the wave keeps rolling, sweeping you side to side in place. Re-engage in phase to thread the gap, and graze the edges for near-miss bonus.

03

Never idle

Playing safe eventually kills you. The game forces commitment — risk is the only way to climb the score.

02 · Solo Modes

Pick your
discipline.

Two ways to ride. One forgiving, one unforgiving. Both end the same way — one collision and the run is over.

CLASSIC

Classic

The pure ride. Forgiving spacing, room to find your rhythm. Build streaks, chase milestones, learn the wave.

Endless Streak tiers Beginner-friendly
FLATLINE

Flatline

Coast for 0.7 seconds and you die. The hardcore variant — constant engagement, zero rest. For players who want the edge.

Hardcore 0.7s idle = death High risk

04 · Verified by Replay

Scores you
can prove.
