A ball spins steadily at the center of your screen. Launch more balls at it, one at a time, without hitting the ones already stuck. Land clean, and you move closer to clearing the level. Hit one that's already there, and you start the level over.
Click, tap, or press spacebar to throw
Coreball has been around for years, and it's built a quiet but loyal following, the kind of game people pass along to a friend with "you have to try this." A few different versions of Coreball exist across the web — see how they compare, including who actually built the original, on our Classic & History page.
You're not rewarded for clicking fast. You're rewarded for reading the rotation, waiting for your window, and committing at the right second. It's a small, almost meditative loop, which is probably why a single round so easily turns into "just one more try" for an hour.
Find the gap between the balls already attached to the core.
Click, tap, or press the spacebar to throw your next ball.
Land your throw in open space, not on a ball that's already stuck.
Fill every gap to move on to the next level. Miss, and the level restarts — but you're back in instantly, so it costs seconds, not minutes.
Levels start easy and ramp up fast. By the time you hit double digits you'll likely want backup — that's exactly why we built a full level-by-level walkthrough hub.
Miss a shot and you're straight back in — no loading screen between attempts.
Your clicks register exactly when you make them, so you won't clip a ball you just placed because of input lag.
No paywalls, no "watch an ad to continue," no premium currency, no app to download.
Desktop, laptop, school Chromebook, or your phone on the couch — same game, same progress logic.
If your network filters game sites, our lighter, faster-loading unblocked version is built to get around that.
Our Cheats & Hacks page covers the honest techniques that actually help.
Yes, completely. No sign-up, no hidden costs, and no premium version gating extra levels behind a paywall.

More than you'd probably guess, and they get genuinely difficult the further you go. Our Levels & Walkthroughs hub covers every stage.
Not in the exploit sense, but there are real techniques that actually help. We cover what genuinely works, honestly, on our Cheats & Hacks page.
If your network is blocking the main page, try our dedicated unblocked version; it's built to be lighter and more likely to load on restricted networks.
Don't worry if you get stuck early — half the fun of Coreball is the climb back from level 1, and we've got guides waiting whenever you need them.
