Logic Masters Deutschland e.V.

Rules:
• Draw shivers in the grid such that all unshaded cells are covered and no shaded cells are covered.
• Shivers are non-intersecting lines of at least length 3 which turn at 90° angles on every cell other than their endpoints.
• A dashed circle indicates an endpoint of a shiver.
• A number in a cell indicates the length of the shiver occupying that cell.
• Length is counted in cells, and X indicates clues have the same value.

(A shiver can have 0, 1, or multiple clues.)
