Great game

Love how you can enter a sudoku puzzle. Love how it automatically puts in the hints after you have entered your puzzle and takes away. The hint marks after you placed a for sure number.

Nice teaching aid!

Teaches you all the techniques needed for solving difficult puzzles. I especially love the feature where it tells you the “next technique available” without giving away too much. Great job, developer!

Excellent layout and design

I downloaded this app because I wanted to improve at Sudoku and not get stumped by the more difficult levels in magazines and such. This app did teach me a lot of techniques that I didn’t know before, and if you’re willing to use the hints, the hints are very well-done and informative. I’ll be honest and say I haven’t been able to understand or apply much beyond the Core Chaining Techniques, but what I’ve learned from just the first few techniques has helped immensely, and I rarely get stumped by commercial puzzles these days, even ones marked as Hard.

But what I’d really like to compliment, is the layout and design of the puzzles and keypad. There’s a little bit of a learning curve, getting used to the format, but after a minute or two, the gameplay is so fast, logical, and efficient, I’m actively irritated by the formatting of other Sudoku apps now. I strongly recommend this app just for the ease of play. I’d like to make the suggestion that the keypad numbers could be darkened out as they’re completed, but besides than that one small thing, all the other Sudoku apps could learn something about facilitating smooth gameplay.

Drawn to make a review

I’ve never written a review for any of the many apps I’ve used, but this app is just too good not to share! This is the handhold and guidence that I was imagining when seeking an app to learn Sudoku, and it is even better than I imagined! I’m 5 strategies in and am certain that I’ll be becoming a Sudoku master!

A brilliant app!

I discovered this app from an AI search engine. It is the best one I have come across. It teaches you many basic to very advanced Sudoku solving techniques. It does this by taking you through different levels of technique with demonstrations, several (free) example boards per technique and an impressive hint system that really works without getting out of step or simply taking over.

The free boards per section allow plenty of time to practice each technique you are on. Also, you can get stars for solving a board with a low or zero use of hints and mistakes, if that sort of thing helps your motivation (it did me).

What I don’t understand is why it doesn’t have lots of reviews. This is a real gem, in my opinion. After getting to the end of the 10 free games in the section on XY-wings, I bought the game (£4.99) so that I could practice the technique further, even though I had lots of free sections on even more techniques still to go.

Response from developer

Wow, thanks! I really appreciate you taking the time to write your first review 🙂 I’m glad the guidance and step-by-step approach match what you were looking for, that’s exactly what I had in mind when building it. And nice progress already - 5 strategy groups in is a great start. You’ve got a few more level 4 groups ahead, and mastering those will let you solve the vast majority of human-solvable Sudokus. Hope you enjoy the journey 🙂

Absolutely the best!

I’ve been playing sudoku on NYT and getting frustrated when I get stuck. This app gives you exact techniques for when you’re stuck and even the complex tutorials become digestible. Absolutely love this app!

Too buggy to play

Consistently blocks moves that are correct making the game completely useless.

Response from developer

This sounds like a misunderstanding of how Sudoku rules and logical solving work. In Sudoku, a move is not considered correct just because it doesn’t immediately break a row, column, or box. A move is only correct if it keeps the puzzle solvable all the way to the end. Hintoku checks moves in two ways: - If a move clearly violates Sudoku rules (for example, placing the same number twice in a row/column/box, or removing the last possible candidate from a unit), the app will block it immediately and explain why (e.g. “There’s no room for 8 in row 9”). - If a move doesn’t look wrong at first, but logically leads to a dead end later (making the puzzle impossible to finish), Hintoku will also block it and explain that the move would break the puzzle later on. This is intentional and prevents unsolvable grids. In both cases, the move is undone to keep the puzzle valid. If you believe a move was blocked incorrectly, I’m happy to investigate. Please send the puzzle grid and the exact move you tried to developer@hlms.cz - if it’s an app issue, I’ll fix it; if not, I’ll explain why the move isn’t logically valid.
