147
(Published on 19. May 2024, 18:24 by marty_sears)
Dorlir recently challenged people to make a sport themed puzzle, so here's my snooker themed twist on the 159 ruleset.
Rules:
- Fill the grid with the digits 1-7 so that each digit appears once in each row and column.
- 147: A digit in column 1 indexes the position of the digit 1 in its row. (eg if r3c1 is a 6, then r3c6 is a 1.) A digit in column 4 indexes the position of the digit 4 in its row. A digit in column 7 indexes the position of the digit 7 in its row.
- DOUBLES: There is exactly one doubler cell in each row and column, with each digit from 1-7 appearing once on a doubler. The value of a digit in a doubler cell is double its face value, for the purposes of the kropki ball and black line rules below.
- KROPKI BALLS: The score on a coloured ball indicates the difference between the values of the two cells it sits between.
- BLACK LINES: Values of adjacent cells along the black lines have a difference of at least 4 (Dutch Whisper).
Please leave a comment if you enjoy :)
Solution code: Row 6 from left to right

That was a lot of fun and appreciate all the thought put into the board position here!
(The icing was that the last doubler/digit I found was fittingly the 7.)

Don't know why, but I assumed the half circle indicated diagonal adjacency, so only one cell on row two was affected. Surprising how close one can get to a solution in that case.
Great puzzle once I figured that out!

I like this puzzle. Elegant as always. Also indexing sure is powerful.

I don't fancy that shot on the green, especially needing position on the brown...

Another banger from marty. Really enjoyed this one with very interesting ruleset.

Lovely puzzle. My brain kept thinking the middle column indexed 5 because of 159 puzzles!

Thanks for another lovely puzzle with a fun theme! A little trickier for me (probably a 2.5-3*) and I was a little intimidated by the rules to start. But after the break-in and a couple of early deductions the rest flowed smoothly.

A typically beautiful Marty Sears grid! Though this position would make for a very difficult clear up on a snooker table...

Your sports theme was well played.
