Stop at the
exact time.

A target on screen. A running clock. One button. Stop within milliseconds of the target and take the podium — miss and you're back on the grid. A lap takes ten seconds; the career fits in no break at all.

Precision is the only skill that counts

No steering, no corners. The game isolates the one part of motorsport nobody trains: hitting the instant. Four decimals decide everything, and the tolerance shrinks with every level.

Career

50 levels, then the Legendary Season

The margin starts at ±0.500s and closes to ±0.008s. From level 51 it never ends, with a hazard every 5 levels: cockpit blackout, mirrored display, safety car.

Garage

Races that run without you

Your team races while you're away. Come back, collect coins and parts, upgrade engine, turbo, tires, chassis and ECU. Every driver you hire reshapes the car's profile.

Arena

Duels against actual people

1v1 by matchmaking or private code, group Grand Prix and knockout tournaments. Both players race the same target: closest wins. No paid advantage applies here.

Three modes, one button

All of them use the same gesture — pressing at the right moment. What changes is what's on the line.

ChronometerThe target appears, the clock runs, you stop it. A delta of 0.0000 is a perfect lap.
ReactionFive lights come on. The instant they go out, launch. Jumping costs you the lap.
DodgeTraffic ahead: dodge inside the right window, as many times as the track demands.

Install it as an app

It's a web app: open it on your phone, choose “add to home screen”, and it runs full screen — no store, no manual updates. Energy refills even with the app closed.

Open the game

Fair by construction

Two decisions worth saying out loud, because a precision game lives on trust:

Official time

Your input is what counts

The recorded time comes from the input event's own timestamp, not from the frame drawn on screen. Visual hazards mess with what you see, never with what is measured.

Economy

Currency is a one-way street

Coins and diamonds are earned by playing and spent in the game. No cash-out, no conversion to money, and nothing you could buy carries into a duel.

Progress

Your save is yours

You can play with no account. Create one and your progress syncs to the cloud and follows you across devices — and you can delete the account and its data whenever you want.
