Fun and easy

Sudoku is a puzzle game that has gained immense popularity in recent years. It is an exciting and engaging game that can help you relax and unwind after a long day. As someone who has played Sudoku extensively, I can say without hesitation that it is an incredibly enjoyable and satisfying game. One of the main reasons why Sudoku is so relaxing is that it requires you to concentrate and focus your mind on a specific task. This type of mental engagement can help you forget about the stresses and worries of daily life, allowing you to immerse yourself in the game and enjoy the process of solving the puzzle. In addition to being a relaxing game, Sudoku is also incredibly fun. There is a sense of accomplishment that comes with completing a difficult puzzle, and the feeling of satisfaction that comes from solving a puzzle can be addictive. As you progress through the levels of difficulty, you will find yourself becoming more and more invested in the game, constantly pushing yourself to improve your skills and solve increasingly challenging puzzles. Overall, I would highly recommend Sudoku to anyone looking for a fun and relaxing way to spend their free time. Whether you are a seasoned puzzle enthusiast or a newcomer to the game, Sudoku offers a unique and rewarding experience that is sure to keep you coming back for more. So why not give it a try and see for yourself just how relaxing and fun Sudoku can be!

Why I’m dumping this app.

1. Their idea of an award mid game is to give you a smiley face 😊 tell you to keep going whenever you clear a number off the board then immediately send you to a commercial. Commercials are fine between boards or if you make to many mistakes and want to stay in the game, but it’s just too much forcing them on you even when you’re doing well. 2. It doesn’t give you the option to make sure the choice you’ve chosen is the choice you actually intended to make, in other words if your finger is slightly too far too the left or right when selecting you get a mistake, and you only get two or it’s right back to a commercial. 3. Errors by AI rarely happen but sometimes you make the right selection and it’s marked a mistake. 4. Or you hit second chance and after watching the same commercial for the 500th time, it starts you all over instead of giving that second chance. Overall it’s fun to play at the beginning and for a while, but eventually you just get so frustrated with all these things that you just can’t play it one more time.

One of best Sudoku apps

I’m updating my review. Still an awesome sudoku app, and I’ve played almost all the apps out there. Some of the new features keep me hooked. For example, the events is great. Sometimes my brain gets tired of always playing expert or nightmare levels so it’s nice to play some easy levels. Plus, it has a clear goal for me to work towards. And also, cross math is an interesting concept. It’s great for my son to practice his math, and I never would’ve found out without playing this app. (Previous review) I’ve been playing Sudoku for a long time, and this is one of the best mobile apps for Sudoku. A few things, it has a very clean and easy to use interface. When I click a number, it highlights the corresponding row, column and square, so I can easily scan the board to find other potential numbers. Also, when I write notes and tap a number, all notes with that number are also a different color, so it’s easy to see which cells have that number, and I can start doing deductions more easily. Finally, it has a hint feature that explains how a cell came to a number, which is better than other apps I’ve seen that just directly tell you the answer. Overall, there are many advanced features for the seasoned Sudoku player, but also great for newer players. Would highly recommend this app.

Here for Cross Math

As someone who loves math (to a point of majoring in it in college), I love the cross math portion of this app. People who keep saying the cross math puzzles don't add up, double-check your solutions. So far I've done 94 puzzles and never had any issues about the math not adding up. Only reason I'm not giving this a full five stars is that it tends to be slow on my phone and a lot of times I have to restart the app or pause and resume intermittently just because it keeps lagging when I try to solve the puzzles but the timer is working just fine (my competitive self doesn't like that lol). ------ 8/28 EDIT: Since the most recent update, my cross math time records for all levels except for levels 1-4 got wiped out. I'm talking about 102 frigging levels here. Cross math also became ridiculously easy as well. Oh and level 127 DOES have a math error and is keeping me from moving on to the next level. So this is where I stop playing, I guess. Not to mention the fact that the app still lags when played for more than a few minutes (either in cross math mode or sudoku mode)... This update just made it worse and is such a disappointment.

Best simple sudoku on the App Store.

Perfect classic sudoku game. The best on the App Store. Like the app and the ads are tolerable unlike most free games. That said, I find that if I get stuck and need a hint, the ‘watch an ad to get a hint’ feature rarely works. Watch a very long ad that’s nearly a minute long, with three or four ‘next’ or (X) you need to hit to finally be back to the game and you still have no hint available. The same apoes if I don’t complete the daily challenge and want to watch an ad to play the previous day’s challenge. It would be less aggravating if the ads weren’t for the absolute worst garbage possible. Still a 5 star app with that annoying bug.

Loved it!!! Until…

Definitely the friendliest user interface I’ve played with for sudokus. Then the past few days I’m having issues where ads don’t come up, which sounds good, but I mean it’s literally a black screen where if you click anywhere, the App Store does pop up for the ad it’s supposed to be showing, but I think this also means there’s no exit button (after 30s) since the screen is black. That means I can’t watch ads to access previous daily challenges, extra hints, advanced notes, etc. Outside of that, the only improvement I would suggest is maybe a slight change in tint for the background when you’re in notes mode. Its really the only way I make mistakes nowadays is that I forget that I’m not in notes mode since there’s not much of a noticeable difference when it’s toggled on and off.

Too Many Ads

This app is unbearable to navigate. There are so many ads. You get an ad before starting and after finishing every game. And the one you get after finishing a game occurs before the “Congrats” screen which just ruins the dopamine rush of successfully completing a game. It’s basically a punishment for playing. Additionally, sometimes if you take too long, an ad occurs mid-game and your app starts glitching out forcing you to close and reopen the app to which you are greeted with yet another ad. You also have to watch an ad for almost every feature as well (ie. Hint, Advanced Notes, extra lives), which I actually don’t find too bad — paying for convenience of certain features is understandable… Except that it’s the same 2-3 ads every time. (And it’s always those ones for other crappy games that you know are falsely advertised.) I recommend avoiding this app.

Fun and entertaining

This sudoku app is great. I’ve had it on my phone for a few years and really enjoy the daily challenge puzzle. It’s a great break from work or whatever. There are different game modes including classic sudoku, shapes, unlockable backgrounds, various challenge quests to earn medals, and even Cross Math for a sudoku break. Best of all is that I haven’t encountered any sort of paywall. The ads are minimal and really only play after you’ve beaten a puzzle or if you are continuing a previous puzzle. This is a great app and is lots of fun. 10/10 would recommend to any sudoku lovers. Oh and, in my opinion, the expert puzzles are more difficult than the nightmare puzzles. Have fun!
