Box Twist

(Eingestellt am 8. November 2022, 18:31 Uhr von FullDeck-Missing)

A gentle introduction to some of the logic about how modular lines interact with killer cages.

Normal sudoku rules apply. Each row, column, and box must contain a complete set of the digits 1-9.

Normal killer cage rules apply: digits in cages cannot repeat and must sum to the number shown in the upper left corner of the cage.

Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line if allowed by other rules.

Try the puzzle on the Sudokupad app by Sven Neumann.

Lösungscode: Column 5 (top to bottom); nine digits, no spaces

Very nice puzzle. Took a couple of restarts to get the Modular lines rule set worked out, but after that it fell nicely. Thank you

Yesterday I stared at a juice box for four hours because it said, "Concentrate." Enjoyable and approachable. Thank you.

Very nice GAS puzzle. Two hats please!
I still find modular lines a bit unintuitive compared to entropic lines, but this helped.

>>Two hats duly awarded! Glad you enjoyed it and it helped with the modular lines intuition.

Nice puzzle! It is indeed approachable and (as intended) felt like a great introduction to modular lines plus killer cages. Thank you, FullDeck-Missing!
