Hybrid Sudoku with Renban Groups (Anti-Knight, Non-Consecutive, Non-Touching)
(Published on 17. January 2011, 22:48 by zhergan)
Place the digits 1 to 9 in every row, column and 3x3 standard block. The following three rules must be satisfied:
*** Cells connected with a chess-knight move could not contain same digits.
*** There exist no neighbouring cells with consecutive digits.
*** Two same numbers can not touch each other diagonally.
Besides grey painted cells form renban groups. These groups must hold consecutive digits, in any order.
Solution code: First give the contents of Column 3 and Row 7, then give the digits which are included at least in 4 (out of 5) different renban groups descending in order.
