Best Sudoku App… a couple requests

This sudoku app is by far the best one and the controls are very intuitive. I have found that the extreme classic sudokus take no more than 6-10 mins to complete, and I would love an even higher difficulty. The diabolical puzzles that are released on special occasions are exactly what I’d want. My main request would be to add a section that lets you create a sudoku puzzle. There is a solver that can only solve classic sudokus, but I’m referring to a creation area that lets users make puzzles with any rule set they want. You could even allow for publishing where people can try out others’ puzzles. My only other suggestion would be to allow the highlighting of pencil marked numbers. When using hints, there will sometimes be highlighted pencil marks, like for the 3D Medusa, that would be much easier to find as a solver if I could highlight individual numbers myself. I currently have a work-around that involves highlighting a cell with a color I have designated a number to, which works, but is much less intuitive. 3D medusas and some of the other more complicated strategies are almost impossible to see without a feature like this. Overall this game is amazing, and these suggestions are only minor improvements to the nearly perfect app you have created. If I could give more than 5 stars I would. Great App!

Thank you so much for such a great review. Variant solver - we'll add it to our wish list. As for highlighting individual pencil marks, can you please write to and elaborate. Are you familiar with the ability to use the free drawing feature in the highlights panel? , Thanks again for such a great review.

Best variant sudoku app. Premium is worth it.

This is hands down the best variant sudoku app available. The puzzles are well thought out. The solving experience and features are intuitive and make the app easy to use. And the hints help when you get stuck on particularly complex puzzles — or when you missed something obvious 😅 In the premium version, you get access to more variants and an upcoming master level of difficulty. These things, plus no ads, make it absolutely worth paying for. I’m on a lifetime subscription. And if you’re a variant sudoku lover, it’s a no-brainer to pay for premium. The app also includes weekly special challenges which have a theme and sometimes use new variants not otherwise available in the app or they combine the variants in fun ways. The app also has educational guidance which is really helpful if you’re new to a variant. And there are older posts with introductions to advanced solving techniques which are also helpful. (By the way app developers, you could totally create another section of the app for those to make them easy to find! And maybe link to them in the hints when a certain technique is used in a puzzle, eg - an x wing).

The only game I play!

I quickly became bored with traditional classic Sudoku, but I love this app with its endless variations, which allow me to stretch my brain and which makes each game a unique playing experience. The multiple difficulty levels let you tailor the game play to the desired level of challenge, and the multiple user-friendly settings allow customization of play experience. Even the free version allows for endless hours of play, and the infrequent ads are not terribly intrusive. The paid Premium version is also a reasonable price. I love the frequent bonus ‘Adventures’ that honor users, significant dates and current events. The creators of this app also seem like genuinely good folk - they responded immediately when I submitted a question/suggestion, and they are constantly updating the app to make it even better. Can’t recommend this app more for people who want a more challenging Sudoku experience!
