Theme: GMP (see Bridge Shapes)

Author/Opus: This is the 1st puzzle from guest contributor Gomatamago.

Rules: Shade some cells to make sunglasses. The sunglasses consist of a bridge (a given line, in red) and two lenses made out of orthogonally connected black cells that are symmetric with respect to the perpendicular bisector of the bridge. Two lenses may not share an edge, but can intersect at a point. Cells with the bridges are not shaded, except at the bridge ends. The numbers on the right and bottom edges of the grid indicate the number of shaded lens cells in that row or column.

Also see this example:


Answer String: Enter the length in cells of each of the black lens segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. This example has the key “22,121,12”.

Time Standards (highlight to view): Grandmaster = 5:30, Master = 9:15, Expert = 18:30
