What makes it a run and not a slot car track
The track is vertical and it is built out of what a marble run is made of: pegs that scatter the pack, ramps that throw you sideways, funnels that jam everybody into the same gap and barriers that break when enough marbles hit them. What it adds is the other seven. They take your line, they steal your boost pad and they knock you into a wall at the worst possible moment.
Five trials, five different rules
Same balls, five completely different ways to lose them.
- The Great Race
- A dash to the finish through breakable barriers, boosts and a lot of shoving.
- Lava Run
- Outrun the LAVA and reach the cave. Last one there is lava.
- The Carousel
- Stay on the spinning plate. HOLD the button to pull yourself back in — it burns fuel.
- Red Light
- Run on green, freeze on red. Move one pixel too late and you are out.
- The Hunter
- A hungry predator chases the swarm. Stay alive longer than everyone else.

Questions people actually ask
- Is it multiplayer against real people?
- Not yet, and it would be easy to pretend otherwise: you run against seven opponents that play the trial the way you do, with the same boosters and the same free first use. Nothing waits for a lobby, you press play and the run starts.
- Is it really free?
- Yes, and there are no ads. Coins buy extra uses of the in-match boosters and gems buy looks, but every booster button is free on its first use in every run — for you and for the bots — and the super move is never sold, you earn it by playing.
- Do I need to download or install anything?
- No. There is nothing to download and no account to create. You open the page and you are in a trial.
- Can I play it on my phone?
- Yes. It works on a phone and on a desktop browser. One tap and you are rolling.
