Boy Howdy's Expert Sudoku has four tricky types of Sudokus to try:

• X Sudoku is the same as regular 9x9 sudoku, but both diagonals must contain 1 to 9 once only.
• Hyper Sudoku is 9x9 but with an additional set of four 3x3 blocks that must contain 1 to 9 once only.
• Jigsaw Sudoku is 9x9 but instead of 3x3 smaller blocks, the blocks are shaped like jigsaw pieces.
• Samurai Sudoku (iPad only, because it's HUGE!) is a super combo of five regular 9x9 sudoku puzzles, overlapping on one corner of one of the 3x3 blocks.  Note that the normal row/column constraints are only within each 9x9 square.

• There are 40,000 Sudokus for each of the four types!  (10,000 Easy, 10,000 Medium, 10,000 Hard, and 10,000 Evil Sudokus)

## Expert Sudoku Book Stress Free Reviews in United States

### ***** "Cool game."
This is a really great game. There are several levels and everyone can find a challenge.
-- jbzimmer, 2025-03-06

### ***-- "QoL improvement please"
I didn't play much because I didn't like having to always click a box then click a number and repeat. I would like to be able to hold that number and click on the boxes all at once. Thanks!
-- Mayleene, 2024-06-20

### ****- "Problem with Expert Sudoku"
I enjoy playing many of your games with Sudoku being one of my
favorites. However, just in the past few days there seems be a glitch. When I am trying to put my numbers in the boxes, the numbers often will jump to a different (wrong) square which can be quite annoying. It would be great if you would check into this. Thank you for many hours of normally relaxing entertainment!
-- ABCDEFGHIJKMENOP, 2024-06-18

### ***-- "Needs a timer"
I really miss a timer. A second feature I love but can do without is a bookmark. The sales screen also states you can turn off certain features but no option exist in settings. Other than that for a free app it’s great. The ads are unobtrusive I intend to click on one occasionally to send some funds to the developer.
-- InqZael, 2023-09-07

### ****- "Pretty good"
If you have an undo button, you should also have a redo button. If you accidentally hit the button and don’t see what changed, there’s no way to correct your mistake. 

Challenging games.
-- kgsm96, 2023-07-31

### ***** "Expert Sudoku"
Expert Sudoku is a fantastic, GREAT , INTERESTING game!  Glad I have it! 👏👏👏
-- CeeCo, 2023-06-06

### *---- "Bob"
I like the game, but it keeps pausing, makes me suspicious
-- bobsfingers, 2021-08-26

### ***** "Awesome"
Great game. Fun.& challenging!
-- Solo Gram Master, 2021-03-04

### ****- "Love it, but....."
I truly do love the game. However, there really should be some sort of game statistics available. Even something as simple as Number of games played, won, and lost.
-- Vivienne379, 2020-11-30

### ***** "I love the samurai version of Sudoku."
And this is the only one of the few I’ve found online. It’s a very good format. I got an immediate and personal response to a question I asked. It is very simple. Obviously the lower levels at least are meant for new players. I am enjoying it very much n
-- Hate this format, 2020-10-16
