How to play
Click, tap or press space
to throw a ball at the spinning core.
Wait for a gap
The ball flies in a tenth of a second, and the core keeps turning while it's in the air, so aim slightly ahead.
Don't touch a stuck ball
Hitting one ends the run.
Clear the level
Land every ball in the counter to move on.
Watch your combo
Landing three or more in a row shows a streak counter.
The three modes
| Mode | How it works | Best for |
|---|---|---|
| Levels | Numbered levels that get harder. Level 7 is always the same level 7, for everyone | Steady progress and chasing milestones |
| Endless | One core that speeds up the longer you survive. Your score is the balls you land | A quick run with a high score to beat |
| Daily | The same core for every player, chosen by the date | Comparing your run with friends on equal terms |
The daily challenge changes at midnight UTC, so everyone gets a fresh core at the same moment wherever they are.
What makes each level harder
| Change | What it does to the core |
|---|---|
| Speed | Rises with the level number, from a gentle turn up to a fast spin |
| Starting balls | Later levels begin with balls already stuck, leaving fewer gaps |
| Reverse | The core flips direction every couple of seconds |
| Pulse | The spin speeds up and slows down smoothly, so the timing keeps shifting |
| Accelerate | The core gets faster with every ball you land, so the last few are the hardest |
A core fits 26 balls at most, and no level is allowed to fill more than 58% of it. That cap exists because a fuller core has no landing gap left, which would make a level impossible rather than hard.
Tips to get further
Throw into the biggest gap, not the nearest one. Wait half a turn if you have to.
Aim ahead of the gap. The ball takes a moment to arrive, and the core doesn't wait.
Slow down after a near miss. Most runs end on the throw straight after a lucky one.
On reverse levels, throw just after the flip. The core is slowest right as it changes direction.
On accelerating levels, spend your early balls quickly while the core is still slow.
Use Endless to warm up. It starts gentle and builds, which is good practice before a hard level.
Frequently asked questions
How many levels are there in Core Ball?
There's no fixed end. Levels are generated, so they keep coming and keep getting harder. Every level number always produces the same core, so level 12 is identical each time you play it and identical for everyone else.
Is my progress saved?
Yes, on your device. Your current level, best level, best endless run, today's daily score and your chosen ball skin are all kept, so you can close the tab and carry on later.
How do I unlock the ball skins?
By reaching new levels. Classic is available from the start, then Ice at level 5, Toxic at 12, Sunset at 20, Nova at 30 and Void at 45. Each one changes the colour of your balls and the core.
What happens at level 10, 20 and 30?
Every tenth level is a milestone: confetti fires, and the card tells you how many levels you've cleared and names the next milestone. Every fiftieth level gets a bigger celebration. If you've just gone further than ever before, the card says so.
Why do I keep losing on the same level?
Usually because of the rotation pattern rather than the speed. Reverse and pulse levels change their timing while your ball is in the air, so a throw that worked a second ago misses now. Watch a full turn before your first throw and pick the widest gap.
What is the daily challenge?
One core, chosen by today's date, that's the same for every player in the world. Your best score for the day is saved so you can try again and compare. It resets at midnight UTC.
Can I play Core Ball on a phone?
Yes. Tap anywhere on the game area to throw. The core, the balls and the controls all scale to the screen.
Does the game keep my daily score from yesterday?
Only your best for the current day is shown. Each date has its own challenge, so yesterday's score belongs to yesterday's core and isn't carried over.
