Every ball has a face, a mood and its own way of falling apart. One of them is yours.
Collect balls with their own looks and personalities, level them up and dress them with trails and skins.
Five arenas live right now, each with a completely different way to win. More trials on the way.
Win trophies, rise through the ranks, finish daily challenges and push your season pass forward.
Same balls, five completely different ways to lose them.

A dash to the finish through breakable barriers, boosts and a lot of shoving.

You can watch these on the channel today. They are on the list to become playable.

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

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

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

No eliminations, just greed: grab the most loot before time runs out.
Full tournaments for the story, shorts for the thrill — then go run the trials yourself.
Nobody scripted any of this. The physics did it on its own.
Third tournament in a row that came down to the final trial with nothing to separate them.
Two balls crossed the line so close together we had to slow it down to call it.
The random trial picker landed on Lava Run four times in one tournament. We let it happen.
Four teams, a pool of trials and nobody —including us— with the faintest idea who was going to win it.
Same balls, more arenas. Catch the highlights wherever you scroll.
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.
