I’d be willing to pay the one time fee for everything in the app if I can write my numbers in,,, ### 5/5 — Great sudoku app! *2026-06-16, version 3.7.2* No ads, all features you need for free and bonus ones (charts, custom icons) with an affordable one off (not subscription!!) purchase. Plus the speed demon setting is my favourite and now I can’t go back to other methods of filling in. ### 5/5 — Would Recommend *2026-06-13, version 3.7.2* It’s insane how hard it is to find a not evil app in this age, so good on the devs for making one! ### 5/5 — not evil *2026-06-13, version 3.7.2* what it says on the tin ### 5/5 — Best game for the gym *2026-06-06, version 3.7.2* I go to the gym regularly and between sets I find myself very bored but this game cured that because there’s no ads and you don’t need WiFi to play so 10/10 ### 5/5 — paywall *2026-06-03, version 3.7.2* a lot of the game is behind paywall ### 5/5 — NO ADS AND FUN *2026-06-03, version 3.7.2* Super fun without the hassle of ads or boring puzzles! ### 5/5 — It perfect *2026-06-02, version 3.7.2* This is the best sodoku game it has no ads no payment in game perfect perfect! ### 5/5 — Genuinely best sudoku on the app store *2026-06-02, version 3.7.2* With no ads i find myself even more drawn to this app. I use it in replacement of doomscrolling. ### 5/5 — No tracking, no ads, fantastic *2026-05-31, version 3.7.2* This is the kind of app I feel safer downloading for my kids. And it’s got no nonsense. I ended up buying the in app upgrade mainly because I support the developer for doing the right thing and making a good product without the tracking, ads, and other bull****. Thank you ### 5/5 — 🤍🤍🤍 *2026-05-29, version 3.7.2* Loveeee this game! no adds!!! 🥹🥹🥹🥹 ### 5/5 — Great app *2026-05-27, version 3.7.1* Not only does the app do exactly what it says on the tin (free, no catches sudoku) but the dev has also been active adding and improving features over time. Like the ability to export your game as a gif to share. Definitely recommend. ### 4/5 — pretty good! *2026-05-27, version 3.7.1* genuinely no ads. number highlighting (without highlighting rows or columns). doesn’t penalize for errors (that i know of). only thing is that the hard games aren’t super hard. i only ever use this sudoku app! ### 5/5 — The way Sudoku was made to play. *2026-05-15, version 3.6.9* Such a chill environment to play a simple game of Sudoku every now and then. They do have a paid option but it doesnt push you to buy it. Good game👍 ### 5/5 — A normal sudoku app *2026-05-09, version 3.6.9* No adds + clean ui. No better options ### 5/5 — Fav Sudoku app *2026-04-08, version 3.6.9* Good value, high quality games, and with clean UI ### 5/5 — No ads. Wonderful! *2026-01-22, version 3.6.6* Zero ads. You are limited to a single game per day, but that game has NO ADS. I play once daily and love it. If I ever want to play more, I can always get the premium version. All other apps allow unlimited play with with ads. I hate ads. No thanks. ### 5/5 — The only sudoku app worth anything *2026-01-18, version 3.6.6* That’s it, that’s the review. Get this one ### 5/5 — Perfect *2025-12-17, version 3.6.1* The only sudoku app in my mind ❤️ ### 5/5 — Pay with your money, not your data *2025-12-10, version 3.6.1* Glad to find a nice app with a one-time purchase option. Happy to pay for a well made app with a good interface and no ads. ## Most critical reviews (10 lowest-rated) ### 1/5 — Thought it wasn’t evil *2025-10-20, version 3.5.6* I was excited that upon starting a game I wasn’t barraged with ads but this isn’t the only sudoku game that doesn’t barrage with ads so that not a major win. The major downside to this game is for it to remain “not evil” you have to pay to play more than 1 game a day. That’s evil at its core. If I can play multiple games a day (like I want) for watching the occasional ad that would be better but the developers don’t understand that a person may want to play more than one game. This game is definitely evil and I won’t be reinstalling it. Thank goodness there are others to choose from and sudoku games aren’t rare to find. Don’t bother wasting your time or money on this one! ### 1/5 — One game a day *2025-10-06, version 3.5.3* 👎 ### 1/5 — Its evil *2024-10-07, version 3.1.3* I thought this was a simple sudoku app without adds, but its worse than being riddled with adds. Limits you to one puzzle a day and wants you to pay for premium for more. Stupid. ### 1/5 — Could have been good *2024-08-25, version 2.7.0* lures you in with no ads and a nice interface, then slaps you with only allowing you to play one game per day unless you pay. might as well just play a game with ads. lame. ### 1/5 — No ads but have to wait *2024-07-30, version 2.7.0* No ads is great but haveing to wait 13 minutes to play another game is stupid. Would rather watch an ad then have to wait. ### 1/5 — Disingenuous Advertising *2024-05-28, version 2.7.0* It’s not actually ad free and features are limited ### 1/5 — Only 1 puzzle per day if you dont pay *2024-01-10, version 2.6.2* You'd be better off with a different free app, this one limits you to one sudoku a day and you cant change the difficulty. Not very "not evil" ### 1/5 — 6 hour wait time *2023-12-06, version 2.5.0* You have to wait over 6 hours between puzzles UNLESS you buy their subscription. ### 1/5 — Ripped off! *2023-11-08, version 2.5.0* I paid for this app and it is telling me that I have to wait 10 minutes to start the next game because I’m playing for free. ### 1/5 — Not evil it’s horrible *2023-09-29, version 2.5.0* You can only play one game every 12 hours unless you pay. Don’t download this ## Most praised reviews (10 highest-rated) ### 5/5 — App lives up to its name *2026-08-19, version 3.7.5* (Tldr: if you just want to play Sudoku, look no further in the App Store. This app is perfect.) I’ve been really impressed by this app and it’s author. The app has continued to be refined with each released update. The app has only gotten more user-friendly and even less evil (if possible). There’s no ads, there’s no BS, there’s no jankiness. As silly as it sounds, it’s honestly a refreshing experience seeing an app have this progression, even if it is just a silly Sudoku app. ### 5/5 — A refreshing change *2026-08-14, version 3.7.5* Good to see developers making such things, keep it up. :) ### 5/5 — Amazing *2026-07-25, version 3.7.5* No ads, simple, and just very fun ### 5/5 — Best Sudoku App *2026-07-22, version 3.7.5* You can feel the person that made this actually cares about the game. Not spamming ads everywhere just play unlimited sudoku forever, easiest sudoku app i’ve used by far ### 5/5 — Amazing. *2026-07-15, version 3.7.3* Amazing game. Very good. Im proud of you. Continue being amazing. Make harder levels. I love this. Amazing. Fantastic. ### 5/5 — Thank you *2026-07-15, version 3.7.3* One of the few apps made simply for user enjoyment. Thank you for not selling us to the advertisers. That really is the best part of your wonderful game. Love the "old school" setting. Wish the rankings could be filtered by old school 🤔 ### 5/5 — Fun and No Ads *2026-06-24, version 3.7.2* Truly not evil. Not selling my soul to a corporate who doesn’t care if I play the game. This Sudoku is a hero ### 5/5 — Great *2026-06-21, version 3.7.2* Good ui, no ads, its great. ### 5/5 — peaceful in here *2026-06-19, version 3.7.2* only problem is that speed demon is a little buggy sometimes but i can resolve it easily by closing and reopening the app. i dont even mind that little bit of friction. it makes the app endearing to me ### 5/5 — Sooo Goood *2026-06-16, version 3.7.2* With out any ad --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
