The game

You don't just watch this one

Every ball has a face, a mood and its own way of falling apart. One of them is yours.

Pick your ball

Collect balls with their own looks and personalities, level them up and dress them with trails and skins.

Run the trials

Five arenas live right now, each with a completely different way to win. More trials on the way.

Climb the season

Win trophies, rise through the ranks, finish daily challenges and push your season pass forward.

The trials

Five trials you can play right now

Same balls, five completely different ways to lose them.

More about each trial: The Great Race · The Hunter · Red Light · The Carousel · Lava Run

Shrinking Floor gameplay

⬡Shrinking Floor

The arena vanishes tile by tile. Push or fall: last ball standing wins.

The Platform gameplay

Sumo on a ledge above boiling lava. One good bump ends you.

Saws, pistons and swinging doors. First ones through score big.

The Heist gameplay

Things that happened

The moments people still bring up

Nobody scripted any of this. The physics did it on its own.

2-2-2-2

Four teams. Dead tied. Again.

Third tournament in a row that came down to the final trial with nothing to separate them.

Photo finish

The closest one we have ever filmed

Two balls crossed the line so close together we had to slow it down to call it.

×4

Lava Run came up four times

The random trial picker landed on Lava Run four times in one tournament. We let it happen.

#1

The one that started all of this

Four teams, a pool of trials and nobody —including us— with the faintest idea who was going to win it.

Follow

The trials are everywhere

Same balls, more arenas. Catch the highlights wherever you scroll.

Why it exists

I made it for my son

My son loves ball games, so I set out to make one just for him. I built it by experimenting with AI, one trial at a time, and it grew into this.

It's free, with no ads and nothing to buy. Anyone is welcome to play it.

If you try it, tell me what you think: what's fun, what's broken, what you'd add. If people enjoy it, I'll keep working on it.
