Four Winds
Extend straight arms from every numbered cell in the four cardinal directions. A number gives the combined length of all arms extending from that cell. Arms cannot cross, overlap, leave the grid, or pass through another numbered cell, and every empty cell must be covered exactly once.
How to solve
Complete rules
Goal: Cover every empty cell with an arm extending from a numbered cell. Rules: - Arms extend horizontally or vertically from numbered cells. - A number equals the combined length of all arms extending from that cell; the numbered cell itself is not counted. - A numbered cell may extend arms in one or more of the four cardinal directions. - Arms cannot cross, overlap, leave the grid, or pass through another numbered cell. - Every non-numbered cell must be covered by exactly one arm.
