This is Simon Tatham's open-source collection of 40 single-player logic puzzle games, ported to Android. 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.
