APPROXIMATE SOLVING TIMES:
Level 6 - AutoFill:70 min; Manual: ... well it depends
Level 5 - AutoFill:40 min; Manual: 3 hours
Level 4 - AutoFill:25 min; Manual: 2 hours
Level 3 - AutoFill:12 min; Manual: 1.3 hours
Level 2 - AutoFill: 6 min; Manual: 50 min
Level 1 - AutoFill: 2 min; Manual: 30 min
NOTE: Solving times of advanced Sudoku players.
As in all Sudoku games with AutoFill notes mode enabled - it is just too easy to play level 1, so use it for higher levels.
You can solve it 20% faster using the iPad version.

FEATURES EXPLAINED:
• AutoFill Mode - all notes will be automatically populated and then kept in sync with the numbers you enter. You can remove notes. You can add notes only if you previously removed them. In this mode the game does everything for you and lets you do the thinking. You can switch back to manual mode - the auto-populated notes will remain.
• Manual Mode - you are responsible for adding/removing notes. No restrictions.
• Manual Mode with "smart notes" - you are responsible for adding/removing notes, but the game will auto cleanup the corresponding notes when you enter a new number. If you change your mind and remove the number the game will put them back. In manual mode you can use the "Clear Notes" button to clear all notes.
• Clear notes - in manual mode clears all notes
• Hint - press the "Hint" button and one unknown number will be revealed

ALERT LEVELS:
• OFF - No alerts
• Conflicts Alert - When the entered number conflicts with another number on the same row, column or box it will be colored in red and you will hear an alert sound. Hidden conflicts warning.
• Wrong Number alert - When the entered number doesn't match the real number it will be colored in red and you will hear an alert sound.

DOUBLE-TAP SHORTCUTS - very convenient for this type of big puzzle:
1. If you want to quickly remove a number you entered - just double-tap it
2. When there is only one note in a certain square - double tap it and the note will become the number
3. If a row, column or sub-square is populated with unique numbers and there is only one number left - double-tap the square - the remaining number will appear
Double-tap shortcuts reduce the solving time by 10 - 20%.

NUMBER-FINDER FEATURE:
When nothing is selected tap a number in the notes pad or in the number pad. All squares containing this note or this number will be highlighted;
This feature will allow you to solve the puzzle much faster: 40% in AutoFill mode and 10% in Manual mode.
For some players it is half of the fun to find the correct notes by themselves and solve it without any extra help. Don't use the feature if you are one of those players.


**** NOTE ****
If it looks like you have solved the puzzle, but nothing happens or the numbers don't make sense - please don't write a bad review, but set the alert level to "Wrong Number" to see what is wrong.

## Sudoku 16x16 Monster Reviews in United States

### ****- "Good game but I may delete it"
I do enjoy this game but I wish it would indicate when the game is finished how many mistakes are made.  Also, I don’t know what changed but I can’t see the 2 top left squares because of there is now a little box with 3 colored dots covering it.  I really want to get rid of it but I can’t.  I am seriously considering deleting the game which I really don’t want to.
-- sudoker addict, 2025-10-03

### ***-- "SETTINGS..."
Wish I could (optionally) turn off "Average Time" indication. At my age, I'm not in any big hurry! :) Other than that, I like this game VERY MUCH!!!

Also, user interface: screen doesn’t “want to stay still” — if you select a number, it only stays selected for a VERY short time, even when you’re continuing to hold the number down.
-- Chucklehead 64, 2023-08-20

### ***** "Challenging and different"
Harder than regular Sudoku and very well done. I was wondering if you guys can add regular sudoku with the same features and options?
-- thevl, 2017-03-14

### ****- "Love it"
Finally a challenging sudoku!  I love this game.  Only 1 complaint... The screen is TOO small.  Why are the keyboard numbers & letters so much larger than the grid?  It would help a lot if the game could be played horizontally instead of only vertically.  I love the game, but cannot play it very long before my eyes hurt from straining.
-- ChiliBird65, 2016-09-13

### ***** "Great"
So far the best Sudoku app I have used.
-- QanB, 2014-09-26

### ***** "The best sudoku app I've ever used"
LOVE this app. Tons of puzzles (with 6 levels of difficulty!), all seem to only have one unique solution. Thank goodness because puzzles where the last few squares work several ways drive me CRAZY.  Rarely a bug to be seen.  I use this app constantly and recommend it to anyone looking for something a bit more challenging than a regular 9x9 sudoku. Now that I have 16x16 the smaller ones just can't hold my interest.   Thanks and kudos to the programmer!!!
-- Jtimpson, 2014-09-18

### ***** "Excellent!"
I have tried many automated sudoku a and this is by far the best!!
-- Suz Inverness, 2014-08-30

### ***** "Distilled perfection in app form"
Interface is simple, clean, and fluid. Great game, great app to play it. So many sudoku apps just mess up the feel of the game and this one does it perfectly on top of the fact that no one else does 16x16!
-- Graph713, 2012-10-30

### ***** "If you want a Sudoku challenge, you've come to the right place"
You will work for the reward of completing these Sudoku puzzles. Worth every penny I paid for this and more.
-- nessundorma2000, 2012-09-09

### ***** "iPad update"
Love this app. And it has great support. I didn't need it but made a mistake on my part and contacted them and they were right there helping me. It is well worth it. Thanks for this app and God bless.
-- Rtca, 2012-03-16

### ***** "wow"
i give this app 5 stars because i can't give it 4.99 stars.  it's as close to perfect as i can imagine.  the levels are six kinds of distinctively challenging.  once you choose a level, the interface facilitates data entry so rapid you are working to truly solve the puzzle in record time, not work the interface in record time.
-- macker221, 2011-10-19

### ***** "Fun and challenging!"
I'm totally addicted to this game. I solve at least a dozen puzzles a day and have been for months. I've never experienced an insolvable puzzle (Enzobean obviously did something wrong). Regular 9x9 sudoku holds no interest for me anymore. 99 cents is a bargain for this game.
-- allie8962, 2011-02-24

### ***** "Wow"
Hard on the eyes but that is to be expected. Need more skins. Love the app. More people need to try this. It won't disappoint anyone who finds the 9x9s boring.
-- Becket_9, 2011-02-03

### ***** "Just what I was looking for"
This game is well-made and fun. The puzzles I have done so far were challenging but clear. I like the interface and changeable skins.
-- Rfresa, 2011-01-30
