The 4th Dimension

(Eingestellt am 28. April 2025, 19:01 Uhr von Fenners)

You've heard of the 3 dimensions of Sudoku: rows, columns and 3x3 boxes. Now we enter the 4th Dimension, and you must construct it! Good luck. P.S, Set at 2 stars but may be closer to 2.5. Thanks to CtC Community for testing :)


Puzzle: The 4th Dimension


Rules:

Normal 9x9 Sudoku rules apply.

Extra Region Construction: There are nine, 9-cell orthogonally connected extra regions in the grid you must construct, where each digit from 1-9 must appear in each extra region.

Arrows: The digits on a tail of an arrow must sum to the digit in the bulb. The tail of an arrow is in the same extra region across it's length but in a different extra region to it's bulb. The digit in the bulb indicates how many cells of it's extra region are in it's 3x3 box.

Incredible puzzle! I really loved this. I found it harder than some of the commenters below - about 3.5*

Thanks polcat. Setting a difficulty rating had me stumped to be honest, with many conflicting opinions. It has now settled at 3* which I think is reasonable -- Fenners

As this ruleset contains a new constraint (though similar to CC) I gave 3*. After I got my brain around the walk on the solving path was a great pleasure! Thank you very much for creating and sharing this lovely puzzle.

Happy to hear you enjoyed this, thank you for solving! I was hesitant with the difficulty and originally put is as 3* then lowered it to 2* but with a note it’s more like 2.5 — Fenners

Easy, but nice and fresh. Not too long for a construction. A pearl of 2*.
