From puzzle to picture

Choose your game, then import a photo or screenshot of the complete board. Check the detected grid, adjust its corners or regions when needed, and keep existing pieces pinned. Reveal a one-piece hint or a full solved picture.

Doku Solver supports region-puzzle formats including Meowdoku, Robodoku, Zoodoku and Queens. Recognition depends on the board and game edition; review an uncertain scan before using its answer.

Help on the same phone

The optional Android screen helper can read and place missing pieces in supported native game editions after you grant access and capture a board. Existing pieces stay put, and Stop interrupts the helper. Other editions use screenshot-to-picture guidance. iPhone and iPad use photo or screenshot solving.

Your images stay with you

Puzzle recognition and solving happen on your device, without a Doku Solver account, photo upload, ads or analytics. Read the privacy policy for permissions, temporary images, purchases and support information.

Availability and the full-app unlock

Public availability depends on each app store's review and release status. The Coming Soon buttons on this website do not announce a public release date.

Android editions with a trial counter include ten successfully solved puzzles, followed by an optional one-time full-app unlock through Google Play. The current iOS edition is free. See the support guide for trial counting and restoring a purchase.
