The Tens Digit
(Published on 25. July 2021, 11:50 by SimiC)
Hello! I tried setting a sudoku with a (almost) novel ruleset and this is what i came up with
Rules:
- normal sudoku rules apply
- cages in boxes 2, 4, 6 and 8 must contain the exact same digits (in any order) and must sum to 25
- purple lines are RenrenBanban lines: they are made up of two-digits numbers which must be consecutive (in any order, so for example 52, 56, 53, 55, 54 is a valid solution). Numbers along a line can also be written in any order (so a 16 could also be written as a 61).
- grey lines are nabnaBnerneR lines: they are made up of two-digits numbers which must NOT be consecutive (not even two of them. so 23, 28, 24 is not a valid solution!) and no number can repeat along the line. However (!) the tens digit in a nabnaBnerneR line must be the same for all the numbers.
Tip: be really careful, this puzzle is very tricky and can easily lead you to make mistakes
Have fun!
Solution code: row 9 from left to right, column 8 from top to bottom (18 digits, no spaces)
