This puzzle was made for Scojo's 2026 impostor setting challenge, where each participant prepared a puzzle in their own style and later prepared a puzzle in someone else's style to have the public compare them and guess the real setter. I made this puzzle in the style of Xenonetix and lost the public vote to the original puzzle Factorious.

• Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells.
• Arrows indicate X-Double Arrows, where the first seen digit in the respective row or column is the start and length of a straight Double Arrow, which passes through exactly 2 regions, one containing the endpoints and the other the inner cells of the double arrow. The sum of the endpoints is equal to the sum of the inner cells.
• Cells across White Dots contain consecutive values.
