The game

Easy to start, hard to put down: run, jump and bounce with the arrow keys or the touch buttons. Each episode is short, so it fits into a coffee break - and every one gives up to three stars.

🔴

300 episodes

Five worlds, each with its own look and its own tricks, from the scrapyard road to the clockwork tower.

⬛

Black Box squares

Jump on them, dodge them, outsmart them. Bigger boxes guard the end of every world.

🧩

Switches and puzzles

Lasers, gates and switches: some roads only open when you think first and jump second.

⭐

Three stars

Clear an episode fast and clean for all three stars - and come back to beat your best.

The story of the Sphere Clan

Red Ball belongs to the Sphere Clan - round, bouncy and very fond of their family. One day the Black Box squares came and blocked every road with their boxes.

The road is blocked

The Black Box squares want the whole world flat and square. They stacked their boxes across the road home.

One ball sets out

Red Ball does not like being told what shape to be. He bounces off to clear the road, one box at a time.

Five worlds

Through the scrapyard, the furnace, the frozen lands and the clockwork tower - each world ends with a big square boss.

Home again

At the end of the road his family is waiting. The road is clear, the Sphere Clan is together - and round again.

Questions

Is it free?

Yes. The browser version is free and has no ads. The Android app is free and shows ads from Google AdMob: rewarded ads only when you choose to watch one, and a limited number of short ads between episodes.

Do I need an account?

No. The game makes a random install ID on your device, so we can count how many people play and show you news from the developer. No name, email or password. See the privacy policy.

How do I play?

On a computer: arrow keys or A/D to roll, Space or W to jump. On a phone or tablet: the touch buttons on screen. Hold the phone sideways.

Where is my progress saved?

On your device. Your best stars per episode are also sent with your install ID, for the statistics. You can delete that any time: in the game ("Delete my data") or on this page.

I found a bug / I have an idea
