Best of ANY Sudoku Game
I've tried a lot of other sudoku games but this continues to be the best, most advanced and full-featured one, especially if you want to improve your skills. Amazing training tools.
Update #1: Still the best by far! I would gladly pay a lot more for this particular Sudoku app.
Update #2: Years after I first downloaded this, it remains the best out there. I’ve paid for a lot of games that I wish I had never downloaded, or I got bored with them, but this one remains on my phone as the best Sudoku game available. One nice feature is every day it loads a new set of games, one in each difficulty. If you just want a fast and easy game, you can pick that. If you want a hard one, pick that. If you get stuck, the help starts off as a hint, but if the solution uses a technique you don’t yet know, it walks you through learning it.
Free version is so good I had to upgrade
I've been playing this for a while. I have another free version on my phone, and it has two big drawbacks: 1) lately it is inundated with ads, and 2) if I'm stuck, I can reveal the answer but I don't learn anything.
This version is great because if I'm stuck, there are tutorials, which get more and more in-depth. For a while I didn't understand about the "fatal combination" or whatever it's called -- what it is, there are some number patterns that would allow for two correct solutions. The pure Sudoku always has a solution and only one solution. So in addition to not having two of the same number in a row, column or rectangle, I also can't have a situation where there's more than one possibility. I'm learning. (Slowly). The tutorials proceed slowly, so if I get it sooner, I can return to the game sooner.
Best Sudoku training game ever
I rarely write reviews but this game deserves one. I've tried lots of others in the app store just to get some variety but this is the best one, hands down. The range of difficulty is amazing, I can dial in exactly how hard I want it to be - some patterns are too hard or time consuming for my preference so I can dial it down but still keep it challenging. The tutorials are excellent, the way it compares your time against other players is great, and the puzzles themselves are top-notch. Can't say enough good things about this game. If I had to find an area of improvement it would be the graphics - they're functional but not as nice as some other games out there. But they're not too bad and there are some customization options which are nice. Great game and kudos to the developers!
