Triple Trouble (5x5x3) [Region Sum, Dutch Whispers, Renban]
(Published on 1. August 2024, 14:52 by fractalJim)
Three puzzles in one grid! This 5x5 grid can be solved three times, each time using a different constraint type for the lines. First solve as Region Sums, then as Dutch Whispers, finally as Renban (detailed rules given below). You will need the last line of the grid from each solve in the solution code.
I am very interested to hear feedback on this one, comments most welcome.
5x5 Sudoku rules apply. Place the Digits 1 to 5 once each in each row column and region.
Digits in a shaded box must be even. Digits in a shaded circle must be Odd.
First solve solve the puzzle using the lines as Region Sum lines, region borders divide the lines into sections with the same sum.
Next solve the puzzle treating the lines as Dutch Whispers lines. Adjacent digits on the lines must differ by at least 2.
Finally solve the puzzle using the lines as Renban lines. Digits on the lines must form a consecutive non-repeating set (in any order).
Solution code: Enter the last row of the grid from left to right. First Region Sum Then Whispers Then Renban

Amazing that you even found this configuration that works with 3 different line types. How many possible configurations could there even be?

I really enjoyed this puzzle!! Interesting to recognize constants within all 3 puzzles. Took roughly 16 minutes for me to solve

Interesting to see how different rule sets change the difficulty of seemingly identical grids.

I'm not the biggest fan of the smaller grids, but it was pretty neat seeing one working on so many rulesets.
I concrete feedback on the solution code though. You say we should enter the last "line" of each puzzle, which makes me think of the sum, whisper and renban lines. You might want to change that to last "row" to avoid confusion.

Very nice setting! If you work with lines having a difference of two, you may want to go for "Chinese whisper line", but that is a very minor point.

Loved the different approaches for each puzzle!
