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: 50% in AutoFill mode and 20% 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. APPROXIMATE SOLVING TIMES (without number finder feature): Level 6 - AutoFill:60 min; Manual: ... well it depends Level 5 - AutoFill:30 min; Manual: 2 hours Level 4 - AutoFill:20 min; Manual: 1.5 hours Level 3 - AutoFill:10 min; Manual: 1 hour Level 2 - AutoFill: 5 min; Manual: 40 min Level 1 - AutoFill: 2 min; Manual: 20 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 levels 1 and 2, so use it for higher levels. You can solve it about 10% faster using the iPad version. **** 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.

Verdict
The clearest difference is rating: Sudoku Mega Bundle at 4.8 against Sudoku 16x16's 3.8. Sudoku Mega Bundle also leads on ratings volume (2.9K vs 12). Sudoku 16x16's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Sudoku Mega Bundle sells 4 in-app purchases, starting at $1.99 per month. Sudoku 16x16 asks for nothing beyond the download.
Sudoku Mega Bundle holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Sudoku Mega Bundle has 2.9K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 88% of Sudoku 16x16's written reviews are positive against 78% of Sudoku Mega Bundle's, so the app with the better star average is not the one people write more warmly about.
Sudoku 16x16 ships an update every 3 weeks, Sudoku Mega Bundle every 2 months. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
