Building a track

Open the track editor. Pick Load built-in… to start from a course that ships with the game, or New.
Drag control points in the viewport. The strip along the bottom validates the course live. Send to race and Save stay blocked while it reports errors.
Tools → Switchbacks generates a hairpin stack; Auto-bank banks the turns for the speed marbles actually arrive at.
Tools → Reference footage takes a video or screenshot of a real marble run and pins a frame behind the track so you can trace it.
Press T to test-drive it, then ▶ Send to race. It appears in the track dropdown on the race screen.

How a race works

Open the race on a TV, laptop or phone. It shows a code like BRKT and a QR.
In a hurry, or on your own? Watch a race starts one with nobody steering.
Everyone opens join on their phone and types those four letters.
Tap READY. The host taps START. 3, 2, 1, DROP.
Steer across the track. You can't speed up or slow down, you only pick your line, and spend your two boosts.
You get a team of four marbles in one colour. Your best one scores; tap switch to take over the leader of your set.
Between heats the host picks New heat to keep the standings, or New game to reset them.

Alpha, and honest about it. Phones join from their own devices. Scan the QR on the race screen, or type the four letters. (A second browser window on the same machine works too.) It's an early build, so expect rough edges.

What Marble Rush is

Marble Rush is a free marble race party game for a room of people. The big screen shows thirty-two marbles pouring down a mountain course, and every phone in the room steers a team of four of them. You can't speed up or slow down. You pick your line, nudge left and right, and spend your two boosts while gravity does the rest. It runs in the browser with no download and no account.

How a race plays

Open the race on a TV or laptop and it shows a four-letter code and a QR code. Everyone joins on their phone, picks a name and takes a marble colour, then taps Ready. The host taps Start and the screen counts down three, two, one, drop. Your best-placed marble is the one that scores, and you can tap switch to take over the leader of your set when another one pulls ahead.

A race is short, about two minutes, and it's loud, because the whole room leans when a marble teeters on an edge. Between heats the host can start a new heat to keep the standings or a new game to reset them, so a rematch takes a few seconds. There's also a track editor if you'd like to draw your own course and send it to the race screen.

Players and what you need

One to eight players, each with a phone, and one shared screen with a browser that everyone can see. On your own, tap Watch a race and thirty-two marbles run it by themselves, so you can pick a colour and cheer. It's still an early build, so expect a few rough edges.
