About Slipline Garage
Slipline Garage is a small, independent project: one original 3D drifting game for the browser, and a site that explains it properly. The promise is short. Find your line. Hold the slide. Beat your best.
What this is
A single arcade drifting game with six cars, four tracks, eight interactive lessons, twenty-four challenges and six modes. It is free, it needs no account, and it runs in a browser tab. It is not a games portal and nothing on the site is embedded from elsewhere.
“Slipline Garage” is a working title. The name, like the domain it lives on, is kept configurable in the project rather than treated as a registered brand.
Who writes the guides
The guides are written by the same people who build the game, credited collectively as The Slipline Garage team. That is the only credential claimed: we wrote the handling model, the scoring rules and the challenges, so we can describe them accurately.
Wherever a guide quotes a number — a threshold, a car’s mass, a medal target — the page reads it from the game’s own configuration when the site is built, so the text and the game cannot quietly disagree. Corner descriptions in the track guides are taken from the track geometry, not from memory.
How it is built
- Handling is a planar tire-force model run at a fixed 60 steps per second. Slides come from grip running out, not from a scripted animation.
- Cars and tracks are original. No real manufacturer’s shapes, badges or circuit layouts are used.
- Sound is synthesised live in the browser from the car’s speed, throttle and tire slip. No recorded or licensed audio is used.
- Images on this site are captured from the game itself.
- Type is set in Sofia Sans Extra Condensed and Hanken Grotesk, both under the SIL Open Font License and served from this site.
What we will not do
- Sell cars, tracks, currency or progress. Everything is free.
- Show fake leaderboards, invented players or made-up reviews.
- Call a compact track an open world, or an arcade model a simulator.
- Claim a device is supported before it has been tested on one.
- Put advertising on the page that hosts the game.
How it has been tested
The simulation, scoring, save system and daily schedule are covered by automated tests, including a check that the same inputs give the same result at 30, 60, 120 and 144 frames per second. Every challenge was completed by the game’s reference driver before medal thresholds were set.
Hands-on testing so far is developer testing in desktop Chromium on Windows. Independent playtesting, other browsers and physical phones, tablets and Chromebooks are still to come, and pages that touch on them say so.
Updates
The current game version is 1.0.0. This site was last updated on . Guides carry their own published and updated dates, and an updated date changes only when the content does.
