Ratings and reviews

No match. I have played this game for awhile forgetting why I quit. You can't get many of the puzzles completed because a straight line needs just one number but that number is already in the nine square box and that same number is also in a different box but above or below you. So if you put that number in, you end up with three red boxes. These guys said to others that these games are solveable. So I'll take a picture and prove them wrong.

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.

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.
