This release was checked with antivirus software on 2026-09-18 using VirusTotal. A quick sanity check on your end: the file should be 114.4 MB, in line with what the original puzzle app weighs. Scan it yourself before installing — on any site, not just this one.
No. It installs like any normal app: allow installs from your browser, open the downloaded file, and tap install. Everything the mod changes — unlimited undo and all themes — is patched into the app itself, not into your system, so nothing needs root access.
Install the newer release over the old one — no uninstall needed, and your local save data carries over. v3.6.0 is the newest build published here; while a mod is installed, keep auto-updates off for the game so the Play Store version doesn't overwrite it.
Mods are built against one exact game version, and an official update changes the code the mod patched. When that happens the mod needs a rebuild — check the version history on this page for the latest supported release, or ask for an update on the requests board.
