About this app

Nonograms, sudoku and kakuro in one app.

Gridlock Logic is a puzzle app from Paper Crane Studio. It was built around one idea: give people a tool that opens quickly, works when the network does not, and does not ask for an account before it is useful.

What you get
• Generated and hand-made sets
• Error checking you can turn off
• Tablet layout

How it behaves
Everything that can happen on the device happens on the device. Where Gridlock Logic does need a server, it tells you before it sends anything. Settings are plain, exports are open formats, and nothing is locked to this app if you decide to move on.

Gridlock Logic is free to download. Optional purchases remove advertising and unlock the full feature set.

Paper Crane Studio reads every support message. If something is broken, write in and it gets looked at — the release notes name the people who reported each fix.

This is a sample listing in the Appcompass demonstration catalogue.

  • Good with caveats

    Solid, but I am holding back a star for now. Importing from my old app lost some of my formatting. Worth the money.

  • Fast and out of the way

    Been using this for about four months now and it has not let me down once. Starts instantly even on my old phone.

    Sofia M. · 2 months ago · version 8.15.1 · 321 found this helpful

  • Nearly five stars

    Solid, but I am holding back a star for now. The widget resets its size after a reboot. Will update this review if that changes.

    Kenji T. · 2 months ago · version 8.15.1 · 327 found this helpful

  • Better than the big names

    Exactly what I wanted and nothing I did not. Updates are regular and the changelog actually says what changed. Will update this review if that changes.

  • Better than the big names

    Been using this for about four months now and it has not let me down once. The offline support is the real selling point for me. Give it a try before you pay for anything else.

    Leila F. · 4 months ago · version 8.15.1 · 226 found this helpful

  • Finally

    Switched from a paid competitor and have not looked back. Starts instantly even on my old phone. Will update this review if that changes.
