Puzzle games with no ads — free, offline, no sign-up.

WHAT "NO ADS" ACTUALLY MEANS HERE

Plenty of apps say "ad-free" and then drop a 30-second video between every level. GridJoy doesn't. Here's the real promise — and the honest fine print:

The fine print, kept honest: two non-optional placements live off the puzzle — a brief interstitial may appear when you return to the hub after a long session, and banners run on lobby screens (Home, Library, Leaderboard). Never on a grid. Read the full story behind that choice on the about page.

WORKS FULLY OFFLINE

Every puzzle is generated on your phone, not fetched from a server. That means no loading screens, no ads waiting to download, and no connection required — solve on a plane, on the Tube, or anywhere the signal drops. Nothing to sign up for, nothing tracking your solve.

It's the calm, offline puzzle game a phone should come with — open it and play, the way these games used to feel.
