I love the ability to change appearance and even includes a symbolic (non-numeric) mode. Only complaint is they dictate one of the settings is not usable at the same time as another "because that would be too easy". It's an optional setting though? Seems like should people play how they want to instead of how you want them to. Edited

Thank you for your feedback. You can start a puzzle with "pre-fill notes" on, then immediately go to Options, switch to "auto-clear notes" then go back to the puzzle. Hope this helps! Our concern was that people might turn on both without realising how easy it would make each game and then not enjoy playing, but we will keep this under review.

I love this app! I've been playing it for years and it's the first app I've purchased the Pro version of because I loved it so much! Thank you for adding more puzzles as I had completed all the hardest ones! However, I believe there is an error with the hints for Puzzle 305 and 311 for Difficulty 5. Using only the hint function to fill in the numbers, the app gets stuck. I put the puzzles in a solver and they work, but the in-game hints are just incorrect. Edited

Finally got an ad-free version for a reasonable price and not some subscription nonsense. Yay! Update May 1,2022: Latest version adds 1000 more puzzles, 200 per level and a few new features including a "next puzzle" button when you complete one. When you use it though, the next puzzle will let you play and complete it without ever starting the timer. Edited

Thank you for bringing this to our attention. We've just released an update to fix the timer issue.

Great game. A few features would be nice: * An optional feature to relabel puzzles (or other transformations). This could make it so repeatedly playing the same puzzle doesn't get easier due to memorization * Come up with a more convenient number entry system. I'm playing one handed and it's difficult to keep my time low because of button positions Edited

Great app. I Have been playing for years. New update suggestion: Could you please bring back the play times listed on the puzzle selection screen. They let you know where you left off if your playing the game over again (as I am). And with the new 'next puzzle' button after you have finished, I don't want to go the next 'un-played' puzzle. Maybe you could add an option? I prefered the single button to return to the selection page. Again, great app!

Thank you for your feedback. We've not removed any functionality so on-going time should still be visible. You may be seeing a bug seen occasionally in timer recording which has been fixed in the newest update. To go to next puzzle, rather than next un-played puzzle, please choose "Puzzle Selection" at end of game + single arrow on right of screen.
