Simon Tatham's Puzzles

Simon Tatham’s Puzzles brings the following use case to an Android phone: 40 classic single-player logic puzzles, playable offline, generated on demand. Its usefulness therefore depends on the quality of the central workflow, the clarity of its controls and whether the supporting features reduce friction in regular use.

It will always be free, with no ads, and playable offline. See the screenshots for the full list of 40 different games. They’re all generated on demand with adjustable size and difficulty, so you’ll never run out of puzzles. Various control options for small screens lets users on-screen arrow keys (can be enabled in Settings), pinch to zoom, and a button to swap press/long-press. These functions form the practical center of Simon Tatham’s Puzzles, allowing the main task to be handled from the phone without requiring a separate desktop process. Individual options may still vary by version, device, region or account type.

Simon Tatham’s Puzzles makes the strongest case for itself when it removes a repeated step from an existing routine. A new user can test one representative task first, confirm that results are accurate enough for the intended purpose, and only then move important data or habits into the service. Beta testers welcome. Join beta tests with the button on this listing. This is Simon Tatham’s open-source collection of 40 single-player logic puzzle games, ported to Android.

The source record reports an update date of 12 September 2025, but availability and requirements may have changed since that snapshot. Feature access can vary by version, region, device or account type, so the current in-app interface is the most reliable reference. Permissions should correspond to functions the user actually intends to use; location, contacts, camera, microphone, accessibility, storage and notification access deserve particular scrutiny when present. The developer’s current privacy disclosure, data-safety information and account-deletion process should be reviewed before sensitive or irreplaceable information is stored.
