Keep up the good work. ### 5/5 — THANK YOU! *2025-06-13, version 1.30* Keeps me mentally challenged.. 😊 ### 5/5 — Joeisome *2025-04-09, version 1.30* Very nice work, enjoyed ### 5/5 — Loving this game *2025-04-07, version 1.30* This game is the best nd I really enjoy playing it on my free time ### 5/5 — Boy Howdy sudoku *2024-12-15, version 1.29* This phone app is great! It allows for choice of difficulty to allow for skill level. It highlights the selected number by color highlighting all of chosen number on the board. The “menu” offers several game modes: difficulty, errors, hints, etc. I use it daily! ### 5/5 — Memory enhancer *2024-10-02, version 1.28* I’ve been playing this game for quite a long time. It enhanced my memory. I am 66 years old and I need something that will help my brain to stay active. This app helped my mental health. ### 5/5 — Great, but… *2024-09-26, version 1.28* The ad crawl annoys the piss out of me. I would gladly pay for an ad-free version. ### 5/5 — Fun *2024-07-26, version 1.28* I really enjoy playing this game since no cost or videos to watch! Thanks ### 5/5 — best sudoku game program *2024-05-27, version 1.28* I’ve been playing sudoku for years and I am loving this program. No switching between notes and regular numbers. Very easy to correct mistakes. Well done y’all! ### 5/5 — Best Ever *2024-05-06, version 1.28* This Sudoku program is the absolute best! It is easy to very easy to use and lots of fun. Enjoy ### 5/5 — By far the best sudoku app I’ve ever encountered. *2024-04-17* Finally, a sudoku app where I’m not completing all two of the free levels, then paying for three more, with ads in the meantime that interrupt & annoy me anyway. This app allows me to play a TON of sudoku at my leisure, easily swapping between different difficultly levels when I so choose. I find the highlighting & note taking features both fun & helpful, and the ads running at the bottom of the screen never interrupt me. The only SLIGHT interruptions are solely from the producers of the app, asking if you’d like to try a different game. You can easily click out and return to your game of sudoku, without waiting for any annoying advertisements to finish annoying you. Additionally, this is the first sudoku app I’ve found that’s actually lasted me longer than a few weeks. I’ve been playing consistently for months now without completing the LITERAL THOUSANDS of levels. Overall, I am extremely satisfied with this app. I hardly ever leave reviews, but I really had to say— boy howdy, great job with this one. ### 5/5 — Sudoku Boy Howdy *2024-03-12, version 1.27* This is the most wonderful game. I have played sudoku for years, but this is better than any book. I love how he will check your work or finish game if it is beyond help. I am retraining my brain and do NOT need ads confusing me. His other games are also very good to play. ### 5/5 — The Perfect Sudoku (I tried many) *2024-03-10, version 1.27* Of 5 different Sudoku downloads or online games I downloaded and tried, this is the one I settled on as best. Not just because it has a clean and clear interface, but it lets you put in your “hypothetical” answers in each box with a minimum of taps … click on a number and it highlights all those numbers on the board (so you don’t waste time looking all over the board for the number 3, for example.) so many nice features like that. Well thought out. Best of all, there are numerous options to control how you want the app to work, so you can set it up very fine-tuned to your preferences. E.g. do you like a whole column and row to highlight when you click on a cell, or not? You decide! As an extra bonus, I just learned it’s written by a mom & pop team who are extremely responsive in customer support (not that any customer support will ever be needed). So it’s a pleasure to have this Sudoku game. Make this the first one you download and try, and you’ll stop with this one. ### 5/5 — The Perfect Sudoku (I tried many) *2024-03-01* Of 5 different Sudoku downloads or online games I downloaded and tried, this is the one I settled on as best.

Easy or hard, long, or short, it is always possible. ### 5/5 — Many puzzles great selection *2023-12-18, version 1.27* This is great for beginners, as you can work your way up to harder puzzles as you get better. For those looking for more challenges, there are more difficult levels. Well done. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not user friendly *2026-01-15, version 1.34* Multiple areas that are not done well. 1-Using the pencil is clumsy. 2- you can’t select a number and place it. You have to select a square the select a number place it. That’s two moves each time. Instead of one 3- completed squares is not highlighted so you can see what you have placed versus the initial numbers ### 1/5 — Hard Level Not Working Properly *2021-04-04, version 1.21* I enjoy doing harder Sudoku puzzles and have been doing them for years. My issue is that this games seems to erase numbers it’s not supposed to, and I don’t know until later in the game. This happened four times in a row. I downloaded a Sudoku game from someone else & had no problems whatsoever completing the harder level equivalent to this one. I uninstalled this app. ### 1/5 — Bad *2016-03-29, version 1.4* I've had this puzzle app for five minutes and the computer filled one of the nines in the wrong place so I can't do it correctly😕👎🏻👎🏻👎🏻 ### 2/5 — Sudoku *2013-05-21, version 1.0* I've tried to play this game on paper and only got a migraine. After using this app I can see the strategy of the game. Thank you! ### 3/5 — Two opportunities *2026-01-17, version 1.34* Gave this two opportunities. Loved it because the ads were almost nonexistent. The problem is I run into boards where there was no path to complete board. Ignored it a few times but very aggravating after putting in the time. ### 3/5 — Soduku *2022-07-15, version 1.22* Great post stroke stimulation! ### 3/5 — Genius level *2020-06-21, version 1.18* Genius level can’t be solved without guessing. Also, hint is not a hint; it’s cheating. There’s no guessing or cheating in Sudoku; must be solved mathematically and honestly. ### 3/5 — Good App *2017-01-07, version 1.8* But has no timer. ### 4/5 — Numbers are so small for the fingers *2025-11-19, version 1.32* It could be better if you can enlarge the numbers and narrow the pencil. ### 4/5 — Bookmarks? *2025-07-12, version 1.30* It would be nice if there was a bookmark feature, to save games at certain spots when faced with two-three potential ways forward, and then get back to the saved spot if the chosen alternative was incorrect. Other than this, pretty good Sudoku app. ## Most praised reviews (10 highest-rated) ### 5/5 — I love Boy Howdy Sudoku *2026-07-27, version 1.38* I’ve just discovered Sudoku and have tried a few different variations and Boy Howdy’s is by far the best. I love how easily you can leave guesses in a box. Now I must get back to the game! ### 5/5 — No time clock = stress free *2026-07-12, version 1.38* My favorite sudoku app because there’s no time clock. Truly a lovely way to unwind. ### 5/5 — Sudoku *2026-06-06, version 1.37* Calms me down and offers space from the craziness of the world. ### 5/5 — Boy Howdy sudoku *2026-05-03, version 1.36* This phone app is great! It allows for choice of difficulty to allow for skill level. It highlights the selected number by color highlighting all of chosen number on the board. The “menu” offers several game modes: difficulty, errors, hints, etc. I use it daily! Two keyboards eliminate the need to continuously toggle keyboard settings! 😊 ### 5/5 — Great app *2026-04-26, version 1.36* I tried several apps after the one I had for several years is suddenly no longer available. This was the only one I found that was similar. I like having the double set of numbers. The only thing is I wish that there was more contrast with the completed numbers. ### 5/5 — LOVE SUDOKU *2026-04-17, version 1.36* First thing in the morning ### 5/5 — My Go-To *2026-01-28, version 1.34* This one’s my go-to for time killing. No WIFI or LTE needed! ### 5/5 — Best Sudoku Ever! *2025-11-07, version 1.32* This is such an enjoyable version of Sudoku! I love it! No Ads! Lots of options for as much help as you need or no help at all, your choice. ### 5/5 — no faff sudoku, great *2025-10-15, version 1.31* It's great that your app is still compatible with my old iPad on iOS9, and that you have dual number pads so you don't waste time and create errors switching between Notes and Placement modes. ### 5/5 — Sodium *2025-10-05, version 1.31* Best app for this game! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
