Editor Reviews

Tested by: Daniel Okafor, Apps and Privacy Editor | Test period: 16 days | Devices: Galaxy S23 FE, Moto Edge 50

slither.io carries roughly 500,000,000+ installs reported by the developer, putting it in the well-established tier inside the Casual category. Pick-up-and-play sessions ran cleanly. Loading screens were short, and the difficulty curve felt forgiving for a casual audience without becoming trivial.

We did not encounter an app crash during normal use; one rare ANR resolved itself after a quick restart.

slither.io sits comfortably for users who have at least basic familiarity with the Casual category. New users will benefit from the in-app onboarding; power users will want to spend time in the settings panel after first launch.

AppsSurf Verdict: mature and stable. Few rough edges remained after multi-day use.

Editor Pros and Cons
Pros (Editor verdict)
  • Pick-up-and-play sessions felt friendly; level loads were near-instant.
  • Quick to install via APK and the package size stays manageable for older devices.
  • Ad placements were relatively contained outside of explicit rewarded prompts.
  • Editorial testing did not surface intrusive ads inside the core experience.
Cons (Editor verdict)
  • Late-game pacing can lean on optional purchases to progress comfortably.
  • Daily reward cadence is aggressive about pulling players back daily.
  • Updates outside the official Play Store require manual reinstall to stay current.
Common Questions about slither.io
  • 01
    Is the slither.io APK on AppsSurf safe?

    We mirror slither.io from publicly-distributed builds and verify each upload before publishing. The same package is rechecked on every version bump. If you have a sensitive device, we still recommend cross-checking with the developer's own page before installing outside the Play Store.

  • 02
    How do I install slither.io from an APK?

    Tap the download button to grab the slither.io package, allow installs from this browser when Android prompts, then open the file. The installer asks for the same permissions Google Play would request. After install, slither.io appears in your launcher like any other app.

  • 03
    What's the minimum Android version supported by slither.io?

    Most builds of slither.io target Android 7.0 and newer. Brand-new flagship features sometimes require Android 11+. Check the version metadata on this page; the build's minSdk is included with each release we mirror.

  • 04
    How do I keep slither.io up to date if I install via APK?

    When slither.io ships a new version, we publish the updated package on this page. You can either revisit this URL periodically or follow the version history at the bottom of this page. APK installs do not auto-update through Google Play, so manual reinstall is the way to track or any subsequent build.

  • 05
    Is slither.io appropriate for the rating shown (Rated for 3+)?

    The developer rates slither.io as Rated for 3+. Our editors looked at the live experience and did not encounter content beyond that rating during the test window, but parental review is always a good practice for any social or open-content category.

  • 06
    How do I uninstall slither.io and clear its data?

    Long-press the slither.io icon in your launcher and pick App Info -> Uninstall, or remove it from the system Apps menu. To clear residual files, also use Storage -> Clear Storage from the same screen. AppsSurf does not retain any of your in-app account data; that lives with the developer.
