Circuit Maker — 3D Racing with a Track Editor

#Racing#Track editor#Online#AI#3D#Free

Circuit Maker is a 3D arcade racer where you build the track yourself: snap straights, corners, crossings and ramps onto a grid — stack bridges and flyovers over other roads — close the loop back to the start line, and dress it up with grandstands, trees and boost boxes.

Choose a track, 1–9 laps and up to 8 racers. Play solo against Easy, Normal or Hard AI, or open an online room and race friends in real time. Thirteen cars — racers, karts, a monster truck and more — each trade off speed, acceleration and handling.

How to play

Press Race and choose a track, laps, racers and your car.
Steer with ← →, ↑ to accelerate, ↓ to brake. On phones use the on-screen buttons. Off track? Press R (↺) to reset.
In the Track Editor, connect road pieces into a loop that returns to the start line, save it, and race it.

Tips

Brake a little before corners, clip the inside and get back on the gas on the way out — it saves a lot of time.
Grass cuts your top speed hard. If you go far off track, press R (↺ on phones) to reset.
Yellow boost boxes give you 1.6 seconds of extra speed and respawn after 5 seconds.
Small (S) corners are very tight. Mixing in M and L corners makes a faster, flowing track.

FAQ

How do I build a track?: Open the Track Editor, pick road pieces and place them on the grid. Tap a piece again or press R to rotate. When the loop returns to the start line you'll see 'Track OK' — save it and pick it in race setup.
Can I stack roads, like bridges and flyovers?: Yes. Use ▲▼ on the right of the editor to pick the level you're editing (0–2) and the Ramp piece to climb one level. Raised roads get pillars automatically and other roads can pass underneath. Roads at different heights must be joined with a ramp.
Can I send my track to a friend?: Press 'Share code' in the editor and send the code. Your friend pastes it in the same window and presses Load. In online rooms, the host's track is sent to everyone automatically.
How do I race friends?: Open 'Race friends online', create a room and share the invite link. 2–8 players; empty seats can be filled with AI. The host picks the track and laps and starts the race.
Where are my tracks saved?: In this browser, and in your account when you're signed in so you can use them on other devices.
