Today is the 43rd birthday of Richard.
This puzzle is a small present for him.
Congratulations!!
Richard published so many brilliant puzzles which I enjoyed solving like many other puzzlers. I wanted to thank him with this sudoku puzzle (since I know that he likes sudokus as me)...
Diagonal Sudoku with Extra Regions & Renban Groups
Place the digits 1 to 9 in every row, column, 3x3 standard block and 4 extra regions painted with grey. All digits on two main diagonals must also be different. Besides green painted cells form renban groups. These groups must hold consecutive numbers, in any order.
Solution code: Row 4, followed by column 3
