[TSL][S1T7] Turn 7: Quattroquadri Potpourri

(Eingestellt am 2. August 2025, 01:27 Uhr von yttrio)

This is my entry for turn 7 of season 1 of The Skunkworks League, hosted by damasosos92. In this round, the prompt was to create a quattroquadri puzzle using only standard local constraints, with a target difficulty of 2 or 3 stars. At least 8 different constraints must be used, and each constraint type can only be used once.

Rules:
Quattroquadri: Place the digits 1 to 9 once each into the 3x3 boxes. Digits may not repeat in the same row, column, or box.

Standard X pairs, Kropki pairs, Arrow, German Whispers, Renban, Region Sum Line, Entropic Line, Modular Line, and Numbered Rooms rules apply.

X Pairs: Digits separated by an X sum to 10.

Kropki Pairs: Digits separated by a black dot must be in a 2:1 ratio. Digits separated by a white dot must be consecutive.

Arrow: Digits on an arrow must sum to the digit placed in that arrow's circle.

German Whispers: Adjacent digits on a green line (also marked with a G) must have a difference of at least 5.

Renban: Digits placed on a purple line (also marked with an R) must be a non-repeating set of consecutive digits, in any order.

Region Sum Lines: 3x3 box borders divide blue lines (also marked with an S) into segments with equal sums.

Entropic Lines: Each set of three adjacent digits along a beige line (also marked with an E) must be one low [123], one medium [456], and one high digit [789].

Modular Lines: Each set of three adjacent digits along a teal line (also marked with an M) must be one each from the sets [147], [258], and [369].

Numbered Rooms: A clue outside the grid indicates the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction.

Took me ages to find the break in, but it's quite clever in the end! Lots of logic that doesn't result in a digit placed before you can get there.
