Region Sum Arrows (6x6)
(Eingestellt am 9. Februar 2026, 01:18 Uhr von Oddlyeven)
Rules: Normal Sudoku rules apply. Put the digits 1 to 6 once each into every row, column and 2x3 box.
Region Sum Arrows: A digit N in a cell with an arrow indicates that there is a straight line N cells long extending from the cell in the direction of the arrow. This line acts as a region sum line: box borders divide the line into segments with the same sum. Each line must cross at least one box border. Consider multiple arrows in the same cell separately.

Prof.Dori made an excellent 9x9 using the same ruleset: Guided Sums.
Lösungscode: Row 4, left to right (6 digits)

This one became so much easier once I understood the rules.
For some reason I was convinced the line starts from the cell that each arrow points to. For future solvers, the line starts from the cell where the arrow is located.

At first intimidating with all of the possibilities. Got to what i thought was the solution but failed to take into account an option in one of the region sum cell. Even so solvable even for an idiot like me. ;)

Looks more difficult than it is, but still a bit of a head scratcher. Great puzzle.

Very nice ruleset and got inspired to create a puzzle on my own also. Simple puzzle but really interesting.
