Coreball FAQ

Coreball is a free online arcade game about timing and precision. A core spins in the center of the screen and you launch balls onto it one at a time, filling every open gap without letting two balls collide. It is the Core Ball game in your browser: one button, 100 levels, and a loop that is easy to understand in seconds but still demanding on later stages. There is no campaign map, no booster shop, and no account wall — just you and the spin.

Yes. Coreball is completely free and runs entirely in your browser. There is nothing to buy, download, or install, and there are no premium tiers, energy meters, or paywalls mid-run. Open coreballplay.com and you are in the arena. The full 100-level climb is included — later stages are not locked behind a purchase.

No. Coreball is a 100% browser-based HTML5 game. It loads in Chrome, Edge, Firefox, Safari, and other modern browsers on desktop and mobile without a plugin, app store listing, or installer. If a page asks you to download a Coreball APK or desktop client, that is not this site.

Yes. Coreball, Core Ball, and the Core Ball game all refer to this free browser arcade game on Coreball Play. The rules are the classic one-button loop: launch onto a spinning core, avoid collisions, climb a hundred stages. Play it at coreballplay.com with no download. Other sites may host similar clones; this page is the rules and FAQ for the Coreball Play version.

Yes. Coreball is a single-player skill game with no chat, no user-generated content, and no in-game purchases. The fantasy is timing balls onto a spinning core. It is suitable as a short-session arcade game for a wide age range. As with any browser game, a parent may still want to check the device’s general web settings.

Watch the spinning core, then tap the arena, click, or press the Space bar to launch a ball. Each ball pins to the core where it lands. Place all of your assigned balls into the gaps without hitting an already-attached ball to clear the level. You get three lives per stage, so a single mistimed shot is recoverable — running out of lives means restarting that level. For a full walkthrough of timing, reversals, and common mistakes, see the how-to-play guide.

Tap or click the arena, or press Space, to launch a ball toward the spinning core. There is no analog stick, no swipe-to-aim, and no reticle — every shot flies to the core, and timing the gap is the whole skill. On a keyboard, Escape leaves focused play and returns you to the level menu. Sound can be muted from the header without affecting progress.

A collision costs one life. You start each level with three lives. The colliding shot does not pin, so you still have to place that ball later. Place every assigned ball before lives hit zero to clear the stage and unlock the next one. If you lose the level, you restart the same stage with three lives again — unlocked progress further down the climb is not taken away.

Lives are per level, not a shared pool for the whole game. Every stage starts you at three. Each collision subtracts one. Clearing the level restores the full three for the next stage. Stats remember the best (highest remaining lives) clear you have posted on each unlocked level, which is a useful way to measure whether you beat a room cleanly or barely scraped through.

A streak counts successful attaches in a row. Each clean pin adds one; a collision resets the streak to zero. Your best streak is stored on the device and shown in Stats. It is a practice metric more than a separate game mode — useful when you are warming up on early levels before a hard reversal stage.

Coreball has 100 progressively harder levels. Early stages teach a steady spin with roomy gaps. From level 25 onward some cores reverse direction at full speed, spins get faster, more balls start already pinned, and you must place more of your own. Level 100 is the end of the climb — there is no endless mode after it, but you can replay any unlocked stage to chase a cleaner clear.

Yes. From level 25 onward, some stages reverse the core at full speed. The first reversal is level 28, then every fourth level after that through level 100. The rest of the climb also gets faster and more crowded, so you cannot rely on one launch cadence for the whole game. When a reverse hits, wait one beat, find a new gap, and start a fresh rhythm.

Yes. Use the level arrows on the home menu to move among stages you have unlocked. Replaying does not lock later levels again. It is the intended way to practice a reversal room or to improve a best-lives clear before you push into the 70s and 80s, where gaps are scarce.

Lead the gap instead of firing when it is already at the bottom. After a reverse, stop for one beat. Spread pins around the ring so you do not cluster shots in one opening. On crowded late levels, take the obvious wide gap first, then pick smaller leftover arcs with more care. You have three lives — use the first miss as information, not as a reason to mash. The how-to-play guide covers these habits in more detail.

Yes. Your unlocked levels, best streak, total clears, and best remaining lives for each level are saved locally in your own browser. Open Stats from the game menu to review them or reset progress. Nothing is sent to a Coreball server, and there is no cloud login. Because the save lives on the device, a different phone, a new browser profile, or cleared site data will look like a fresh game.

Absolutely. Coreball is built mobile-first. Tap anywhere in the play area to launch a ball — the layout adapts to phones, tablets, and desktops. You do not need a gamepad. For the fairest timing, give the arena enough screen so the core is easy to read, and avoid playing in a browser tab that is throttled in the background.

Coreball is a browser game. After the page has loaded you can often keep playing in that tab, but a network connection is needed to open the site the first time. Progress is stored locally in your browser, not in an offline app cache you can launch from the home screen like a native install. If you need a commute-proof copy, keep the tab open before you lose signal.

No official Coreball Play app is required. The game is the website: add the tab to your phone’s bookmarks or home screen if your browser allows it, but you still play in the browser. We do not sell a paid iOS or Android build, and we do not ask you to sideload an APK.

No. There is no sign-up, no email gate, and no profile. Unlocks and stats stay in this browser on this device. The tradeoff is that we cannot restore a run on a new phone for you — copy is not stored on our servers. If you want to start over, use Reset progress in Stats (it asks for a second tap so it is hard to do by accident).

Open Stats from the game menu, tap Reset progress, then confirm with the second tap. That clears unlocked levels, streaks, total clears, and per-level bests on this browser. It cannot be undone. Closing the tab or muting sound does not reset the game.

Local saves vanish if you clear cookies/site data for coreballplay.com, switch browsers, use a private/incognito window that has since closed, or open the game on a different device. OS “lite” modes and some privacy extensions also wipe storage. We cannot recover a deleted local save because it never left your browser. If this keeps happening, avoid private windows and check that the browser is allowed to store site data.

Any current browser with JavaScript and HTML5 canvas support: Chrome, Edge, Firefox, and Safari on desktop, plus their mobile counterparts. Internet Explorer is not supported. If the arena is blank, try updating the browser, disabling a strict script blocker for this site, and reloading. The game needs JavaScript to draw the core and register launches.

Yes. On iPhone and iPad use Safari or another modern browser and tap the arena to launch. On Android use Chrome or your default browser the same way. You do not need an app store download. If taps feel ignored, make sure you are tapping inside the play arena (not a menu button) and that focused play has started from the Play control.
