Grow your turf and slice rival sneks' tails — an offline territory game.
About this app
You are a snek. 🐍 Slip out of your home turf, trace a path across the grid, and close it back into your own territory to claim everything you enclosed — the more ground you take, the bigger you get. But the trail you leave behind is your weak spot: run over a rival snek's trail to knock them out, and never let anyone touch yours.
Movement is clean and grid-based — you step square by square in four directions, and every turn folds the trail like a ribbon of paper. Seal a rival's trail inside one of your captures and they are eliminated on the spot. Corner a bot, close the loop, and watch the whole region flip to your colour.
Your opponents are neural bots: a small reinforcement-learning network trained by self-play, running entirely on your device — no network needed. There is also a hand-written scripted bot for a lighter, cleaner challenge. Switch between a light "paper" theme and a dark one from the start screen, and your own colour is drawn fresh every game.
Features:
* Classic grid-based territory capture — step, draw, and close the loop to claim ground. * On-device neural self-play bots (no network) plus a scripted fallback. * A folded-ribbon trail, smooth "virus" death dissolves, and a live minimap. * Light and dark themes, and a random player colour each game. * A local high score. No accounts, no ads, no tracking, no network access. * Tiny download and fully playable offline.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be paper.loop is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.0.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Paper Loop first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Paper Loop, and a listing is removed when the evidence for it stops holding up.
