A irregular dodecadoku is 12 X 12 jigsaw sudoku. Instead of having nine 3 X 3 blocks, they are 12 areas with irregular shapes. The rules are similar to a classic sudoku. You need to find twelve different digits by column, row, and area.
The digits to be used are: 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C
You have 60,000 enigmas presented in two forms and three levels.
Forms: Symmetrical or asymmetrical.
Levels: beginner, confirmed and expert.
All our 12x12 irregular puzzles are solved with logical deductions. It is not at all necessary to use multiple choices to find any solution.
To better differentiate areas, there are three types of PDF:
• White background.
• Hatched background.
• Shaded background.
• Colored background.
