Rules of a Hexadoku

The hexadoku is a 16X16 Sudoku puzzle. The solving techniques are the same as for the 9x9 sudoku.
Instead of using only the digits 1 to 9, the hexadoku sudoku uses the 16 digits of the hexadecimal base:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F.

Hexadoku printing

For maximum clarity and standardization, all our puzzles are printed in black and white, without shades of gray, color or images.

FEATURES EXPLAINED:
• AutoFill Mode - all notes will be automatically populated and then kept in sync with thenumbers you enter. You can remove notes. You can add notes only if you previously removed them. In this mode the gamedoes everything for you and lets you do the thinking. You can switch back to manual mode - the auto-populated notes willremain.
• 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 noteswhen you enter a new number. If you change your mind and remove the number the game will put them back. In manual modeyou 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 numberon 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 willhear an alert sound.

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

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