Most rounds restart from the game's own menu or the restart button on the end screen. If you want a completely clean state, reload the page. Clearing local storage resets saved scores too, but remember that also erases your best results.

Some browser games include live multiplayer, but Boo Chains is a single-player title. A friendly way to compete is to compare high scores with someone playing on their own device, since scores are saved locally for each player.

No. There is nothing to buy inside Boo Chains - no energy systems, no premium currency and no pay-to-win items. The game is supported by advertising on the page, which is why it can stay free for everyone.

Any current version of Chrome, Edge, Firefox or Safari handles it well. The important things are an up-to-date browser, JavaScript enabled and hardware acceleration switched on. If one browser misbehaves, opening the same page in another is the fastest diagnosis.

Local scores are stored in your browser's local storage. Clearing your browsing data, playing in a private or incognito window, or using guest mode all wipe that storage. Play in a normal window and avoid the clear-cache button if a high score matters to you.

Look for the fullscreen icon in the game's own toolbar, or press the fullscreen key your browser offers (often F11). Maximising the window and setting browser zoom to 100 percent also gives you the largest, correctly scaled view.

No account, email or sign-up is required. You click and play. Progress such as high scores is saved locally in your own browser instead of on a server, so there is nothing to register for.

Stutter is usually memory pressure, not the game itself. Close idle tabs and background programs, pause heavy browser extensions such as large filter lists, and lower the in-game quality setting if there is one. On laptops and phones, letting a warm device cool down for a few minutes also restores normal frame rates.

A blank rectangle almost always means the browser needs a refresh or an update. Close your other tabs, reload the page with a hard refresh (Ctrl+Shift+R), and make sure hardware acceleration is switched on in your browser settings, since many games rely on WebGL. Testing in a second browser tells you quickly whether the issue is the game or your setup.

Active gameplay makes the processor work harder, so some warmth and battery use are normal for graphically busy games. If the device feels uncomfortably hot, pause and let it cool for a few minutes, and close background apps so the game is not competing for resources.
