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.
