I spend time doing the math, checking the lines & sections, when I figure out what to save & delete I have to go through an ad between each one of my choices, making me have to redo all my math again before the next move, another ad & do the process again, causing errors & having to start the game again. Deleting as it causes me more aggression, frustration and anxiety than an enjoyable time. I understand ads are necessary for developers to be able to keep making content for us, however when it gets to this point, users walk away & no ads are being seen. It’s a lose lose situation ### 2/5 — Unnecessary and needless stress that could be alleviated by a simple GUI redesign. *2026-08-21, version 1.14.0* The GUI adds unnecessary stress to a game that should be relaxing. Every time you press the accept or reject button, you have to double check it. If the erase button is already selected, and you press it again, it toggles to the accept button, and visa versa. The fix is to either not toggle, because it’s NOT a toggle button, or Color code the buttons so it’s easy to see the change. My heart rate should not needlessly go up every time I select a number because to erase or accept because of toggle design of the buttons! ### 2/5 — Just ok *2026-08-18, version 1.13.0* Way too many ads - shouldn’t be popping up mid-game, especially after just watching an ad to get more lives. ### 2/5 — Most Adverts get stuck *2026-08-16, version 1.13.0* It’s actually quite a good game but I end up giving up whenever it goes to advert it get’s stuck and you have to close the game to restart ### 3/5 — Too many ads *2026-08-15, version 1.13.0* This game is awesome! However, they start you slow on the ads and then ramp up pretty frequently once you are into it. The moment you pause and then figure out a move, it goes to an ad and you have to start over. It’s pretty frustrating. I’m going to delete the app. ### 2/5 — Too many ads *2026-08-14, version 1.13.0* Super fun math puzzle. Way too many ads. Multiple in between a single game. ### 4/5 — Discrimination *2026-08-13, version 1.13.0* This game would receive 5 stars except it discriminates against people with fat thumbs!!😂😂 make it so you have a setting to turn on/off for all moves to be confirmed!! ### 4/5 — Love the game, but it needs updating *2026-08-12* I’ve been playing this game for months now and I can honestly say that I’m pretty much addicted to it. The only problem for me is that the game seems to be forgotten by its developers… there’s no update whatsoever, not even simple ones, like dark mode. You guys can do better, and I hope you fix the little annoying things. ### 2/5 — love the game but *2026-08-11, version 1.13.0* I hate being interrupted in the middle of the game. I have ADHD and when I'm interrupted it makes me wanna just quit that level because it screws me up. there are SO MANY ADS. You can't get through one puzzle without having about six ads so I am uninstalling it. Come up with a version that only interrupts you when you finish a game and I might reinstall I highly doubt you will do it though because I see many many complaints about the ads from years ago and nothing has been done despite you replying to them saying that you will fix it ### 2/5 — Good game but too many ads *2026-08-11, version 1.13.0* Really enjoy playing the game but the ads are so intrusive and ruin the game play. £14.99 to go ad free….no thanks! ### 4/5 — Love but *2026-08-10, version 1.13.0* I find this app challenging and fun but I, if I’m doing too well I get interrupted by an advertisement. If I’m not doing well I have to watch an advertisement to get more lives. This is fine but definitely not the interruption ads. I deleted this app once a long time ago and now I see why. I will probably delete it again. I like it but not that much. ### 3/5 — Too many ads *2026-08-09, version 1.13.0* Way too many ads. I don’t mind them popping up before or after a game. But to have them pop up 3-4 times in the middle of a game is ridiculous!! That’s a delete for me. Too bad cause I really liked it. ### 4/5 — I like the game but? *2026-08-09, version 1.13.0* The screen has a bright white boarder, terrible on the eyes for playing at night. Unable to dim the screen much because the reminder numbers are too difficult to see. Needs a dark mode option ### 3/5 — More adds than game *2026-08-08, version 1.13.0* The game is really good. It definitely helps me keep my math skills going and I enjoy the challenge. I rated this 3 stars because of the sheer number of ads per game. Not only are there lots of adds that pop up way to frequently than other games, but they have a tendency to show up after one or two plays. I don’t mind some ads, but this game gives more ads than game time. I’m sure it is to buy a subscription, but I have no desire to do that. ### 2/5 — Fun, but soooo many ads.. *2026-08-07, version 1.13.0* Ads pop up every few minutes. It’s too many to really fully enjoy the game. ### 2/5 — Needs shading fix *2026-08-05, version 1.13.0* There needs to be more color separation between the white and the shading of the edit/erase selection and hint selection. A darker shading would help with clarity of play. ## Most critical reviews (10 lowest-rated) ### 1/5 — Fun game but … *2026-08-21, version 1.14.0* Waaaaay too many ads. ### 1/5 — Loaded with Ads!! *2026-08-15, version 1.13.0* Good game but extremely frustrating as you make a couple plays and an ad pops up you have to watch. Makes you lose your concentration and takes forever to play a game. ### 1/5 — Ridiculous adds *2026-08-12, version 1.13.0* Way too many many adds to handle it being fun! ### 1/5 — Fun But Ad Overload *2026-08-09, version 1.13.0* As others have said, fun game but overloaded with ads. Between levels is completely understandable (and consistent with many other games) but multiple ads during the same level is ridiculous and grounds for an immediate uninstall. ### 1/5 — Easy and require no brain *2026-08-07, version 1.13.0* The levels are not new. Old levels keep coming as new ones. Should have thought about giving same sets at different levels. ### 1/5 — So close to being good *2026-08-04, version 1.13.0* The game is fun and challenging. Honestly one of the best puzzles I’ve played. But you get interrupted multiple times within a single game with so many ads. By far the most ads I’ve ever seen. It’s horrible. Makes this game “unplayable” and absolutely no reason to download it. It’s a waste of time and renders the game completely unenjoyable. ### 1/5 — Makes no sense *2026-08-03, version 1.13.0* This game makes no sense. The first three levels are incredibly easy and then the fourth level is way harder than the third. Also I hate that if you get something wrong you lose a life rather than any other game like it where they let you figure it out on your own. It’s difficult to know exactly what number to pick in a row if there’s more than one of the same number. It’s like they expect you to have it perfectly figured out before you even touch the game. I don’t understand how that’s fun for most people. This game needs A LOT of work ### 1/5 — Adds in the middle of gameplay *2026-08-03, version 1.13.0* This is a fun game except that the adds pop up in the middle of playing a round. Aside from annoying it makes the gameplay particularly difficult because by the time you finish the add you don’t remember where you left off. It’s too bad as I was really enjoying this game. ### 1/5 — Terrible *2026-08-02, version 1.13.0* The game would be okay if you ever got to play. The ads are atrocious. 15 seconds of play to every 30 seconds of ads. Then short ads in between. Sorry but it’s a hard NO for me. ### 1/5 — Too many ads *2026-08-02, version 1.13.0* Constant ads that get more frequent and longer over time. ## Most praised reviews (10 highest-rated) ### 5/5 — Too many ad breaks *2026-08-20, version 1.14.0* The game is interrupted by too many ads. ### 5/5 — Make a kids version *2026-08-19, version 1.13.0* My wife and I are addicted to this game! We happily paid the fee to get rid of the annoying ads. I would love to give this game to my grandkids too. I would love it if the developers could specify the dimensions of the grid, starting at 2x2. ### 5/5 — Brand New Game For Me *2026-08-10, version 1.13.0* I’ve played Sudoku and Crosswords but this is so much fun to work on my addition as my new addiction! ### 5/5 — Love it! *2026-08-06, version 1.13.0* I love this game as it makes me use my brain. ### 5/5 — 5 Sterne, trotzdem gelöscht *2026-08-04* Es ist ein echter Jammer, wie dieses wunderschöne Spiel durch aufdringliche Werbung entwertet wird. Nicht in den ersten rund 20 Spielen, aber irgendwann fängt das Programm an, sogar auch noch die laufende Spielrunde selbst mehrfach mit Werbung zu unterbrechen und kann. Damit ist dann die Konzentration flöten und es ist wirklich schwer, wieder ins Spiel hineinzufinden. So bleibt der Spaß komplett auf der Strecke. Schade drum. **Developer response:** Hallo! Vielen Dank, dass Sie sich die Zeit genommen haben, Ihre Erfahrung so ausführlich zu schildern, und dafür, dass Sie dem Spiel trotz Ihrer Enttäuschung fünf Sterne gegeben haben. Es freut uns sehr, dass Ihnen das Spiel an sich so gut gefallen hat. Umso mehr bedauern wir, dass die Werbung Ihren Spielfluss und Ihre Konzentration schließlich so stark beeinträchtigt hat, dass Sie sich zur Deinstallation entschieden haben. Wir werden Ihr Feedback an unser Team weitergeben, damit es bei möglichen Verbesserungen berücksichtigt werden kann. Wer eine möglichst ungestörte Spielerfahrung bevorzugt, kann die Werbung außerdem in den Einstellungen durch eine einmalige Zahlung entfernen. Wir verstehen jedoch, dass dies die von Ihnen geschilderte Frustration nicht ungeschehen macht. Es tut uns wirklich leid, Sie als Spieler verloren zu haben. Wir hoffen sehr, dass wir Sie in Zukunft vielleicht doch noch einmal im Spiel begrüßen dürfen. ### 5/5 — Fantastic puzzle! *2026-07-22, version 1.13.0* I’m playing a ton more of this than I expected to want to do. Puzzles are quick, easy, and if you need to stop in the middle it saves exactly where you were. There’s a few quality of life features, however, that are sorely lacking. 1. Change the color of the last square we touched, please! When an ad pops up it can be hard to remember where you were and it’s annoying to have to figure things out again instead of clicking the rest of the line you were on. 2. Don’t mark an error until we try to touch a number *after* the mistake. Sometimes I forget whether I was on the pencil or eraser. Again, if the last square is colored (maybe red for erase or green for pencil with the number grayed out) we can check our own mistakes. 3. Let us tap the eraser mark on a row or column to erase all the remaining numbers in that row. 4. And most importantly, if all rows and columns are either empty or showing erasers, *please* just clean up the rest of the board for me. I just won. Don’t make me feel like I have to do chores to celebrate. UPDATE: All of the above still apply, but there’s one other thing the game desperately needs. Please drop the ad-free IAP to $5 from $15. If it was lower it would be a no-brainer. As it is, though, it’s ridiculous. ### 5/5 — Love the game *2026-07-15* Excellent game and the amount of ads is acceptable ### 5/5 — Great game *2026-07-07, version 1.12.0* Another game with a twist similar to killer Sudoku ### 5/5 — ADS, ADS, ADS *2026-07-03, version 1.12.0* Very fun game but WAY too many ads. They pop up almost every minute in the middle of a game. THE MOST ads of any game I’ve tried. It’s a good way to force an ‘addict’ to buy a license or uninstall it. ### 5/5 — Great math game *2026-07-03, version 1.12.0* love this game. anytime i feel a hole in my chest and want to cry, i play this game and my mood improves with the brain activation and i also just love math. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
