A real labor of love. Ads are reasonable, and there's no weird extra stuff like in-game currency or lives. There's approximately a BILLION puzzles to play. Seriously, I've played at least one every night for years and I've not even got close to finishing even just the Expert levels. All the different rules will keep you engaged until the end of time. Buy the full version, it's worth it.

edit for March 2026 update: very disappointed with the AI rework. The new interface is less intuitive and uses space less efficiently. The announcement said you could go to the old layout, but it's actually just the row layout in the worse UI. Old review: My go-to sudoku app! Thoughtful puzzles with regular special themes and tons of variants. I like that you can color code and, for certain puzzles, add hidden sums. The paid version is also a reasonable one-time price if you do a lot of puzzles.

I loved the game. The varients were interesting and fun but after playing for a while I started getting ads in the middle of game play. Almost to point where it's after every input (granted I was playing on expert and sometimes had a long time between inputs). Unfortunately I have to uninstall because I absolutely hate games that interrupt game play for ads.
