Sliplap is a free online multiplayer racing game that runs in your browser. Here is everything people ask before they try it.
Play now — freeYes. The whole game is free — every circuit, every mode, online multiplayer and the leaderboards. No download, no account required, and no advertising interrupting a race. There is one optional purchase, Premium at $3 a month, which unlocks racing your friends' and the record holders' ghosts, challenges and a badge beside your name — and changes nothing about the car.
No. Every driver races the identical car. Premium unlocks ways to race other drivers' laps — their ghosts, their replays and challenges — and a badge beside your name, but it does not change your car, the physics or lap timing.
Yes. Create a room, share the four-character code, and up to five players race together on the same circuit under the same conditions. An authoritative server keeps every car in the same place for everyone, so what you see is what they see.
No. Sliplap runs entirely in the browser using WebGL 2, on Chrome, Edge, Firefox and Safari, on desktop and on mobile. There is no launcher, no plugin and no app store.
Two to four minutes, depending on the circuit. Sunset Mile is four laps in about 2:06; Albion is two laps of a 5.9 km circuit in about 3:38. Every race is short enough that the answer to losing one is to start another.
Four: throttle, brake, left and right, plus an instant reset. Keyboard, gamepad and touch all work. The physics underneath is Formula-1-inspired — downforce, weight transfer, load-sensitive tyres, brake lockup and slipstream — but you understand the controls in about four seconds.
Yes. There is a real touch layout — steering under the left thumb, pedals under the right — and the game is landscape-only on mobile. It also installs to a home screen as a progressive web app.
Yes. Lap Records puts you on any circuit for one lap against the clock, from a standing start, with a live delta against your own best lap.
Only laps set alone in Lap Records. A lap driven with anyone else on the circuit — another player or an AI car — still counts towards your career and your history, but it is not ranked, because a slipstream is worth around 30 km/h at the end of a straight and a nudge is worth whatever it is worth. Ranking those against a lap set on an empty road would make the clean laps meaningless. A lap is marked Proved once the server has re-driven your own inputs in an empty room and arrived at the same time.
The only thing a browser ever sends is which keys are held. Positions, lap times and contact are all decided by the server. A speed hack or a skipped lap is not something Sliplap detects after the fact — it is something the protocol cannot express.
The simulation. Most browser racing games model a car as a sprite with a turn rate. Sliplap runs a slip-angle tyre model with load sensitivity, aerodynamic downforce and drag, four-corner suspension, a seven-speed gearbox and a slipstream — at a fixed 120 Hz, on the server and in your browser at the same time, which is what makes it both fair and lag-free.
No. There are three quality tiers and an adaptive resolution governor that targets 60 frames a second, so the game trims its own render scale rather than stuttering. It runs on integrated graphics and on phones.
