How this one works
The light turns green and the whole pack runs. It turns red and everything has to be still. A marble that is still rolling when the light changes is out on the spot, and momentum does not care about your reflexes. Cross the line to win: rushing is how you lose, and so is waiting too long.
Five trials, five different rules
Same balls, five completely different ways to lose them.
- 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.
- Lava Run
- Outrun the LAVA and reach the cave. Last one there is lava.
- The Great Race
- A dash to the finish through breakable barriers, boosts and a lot of shoving.
- The Carousel
- Stay on the spinning plate. HOLD the button to pull yourself back in — it burns fuel.

Questions people actually ask
- Is it the same rules as the playground game?
- Same rules, harder body. You do not stop when you decide to stop, you stop when your marble runs out of speed, so braking early is the whole skill.
- 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.
