## Stress Free Sudoku Game Book! Reviews in United States

### ***** "Boy Howdy sudoku"
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!
-- robert28654, 2024-12-15

### ***** "Memory enhancer"
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.
-- melda525, 2024-10-02

### ***** "Great, but…"
The ad crawl annoys the piss out of me. I would gladly pay for an ad-free version.
-- danwalsh46, 2024-09-26

### ***** "Fun"
I really enjoy playing this game since no cost or videos to watch! Thanks
-- Clk5771, 2024-07-26

### ***** "best sudoku game program"
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!
-- Magnoire, 2024-05-27

### ***** "Best Ever"
This Sudoku program is the absolute best!  It is easy to very easy to use and lots of fun. Enjoy
-- DavidF32780, 2024-05-06

### ***** "Sudoku Boy Howdy"
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.
-- 40july, 2024-03-12

### ***** "The Perfect Sudoku (I tried many)"
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.
-- Dand4, 2024-03-10

### ***** "Sudoku"
It is a good game,  as it is always winnable.  Easy or hard, long, or short, it is always possible.
-- a Physics professor, 2024-02-11

### ***** "Addictive and FUN!"
Really cool game.
-- Rfk$$, 2023-10-22
