Pockets No. 3: L Labyrinth

(Published on 30. June 2026, 15:00 by dogpond12)

Rules of Pockets: Each region has exactly one shaded “block” consisting of orthogonally connected cells inside the region. Numbers/Inequalities represent the amount of cells that are the same type (shaded or unshaded) in its region, including itself. All shaded cells are connected to each other orthogonally.Unshaded cells are either a group of 1 or are orthogonally connected to all unshaded cells that aren’t. There must be at least one pocket. There are an equal amount of shaded cells and unshaded cells. Special Constraint(s): L Lay - Out of groups of 15 cells or more, make regions that are either a L-tromino, L-tetromino, or L-pentomino. Numbers/Inequalities in groups of 15 cells or more apply to the region it lays in, not the group itself. Click the image to play on Penpa+.

Solution code: Amount of shaded cells in each column, starting from Column 6 and going left to Column 1, followed by the amount of tetromino regions made.

I am sorry, but this puzzle still has multiple solutions (see hidden comment again)

The old puzzle had multiple solutions, this one should only have one

As far as I understand the rules, the two large regions have to be divided into L-shaped parts, for which then the normal rules apply.

Unfortunately, in my opinion this leads to multiple solutions (I found at least two that are not the intended solution, see hidden comment) as there are quite a few ways to divide those regions.

I really like the general new concept and the first two puzzles. But here I don't understand the special contraint. Where do the L-shapes appear? As shaded cells in a region? as unshaded cells in a region? Are there - against the general rules - more than one shaded group? The examples seem to me as showing rather the general rules, not the special L-part.

dogpond12: The L-shapes are the regions, not purely shaded or unshaded, something I should've explained more in the rules.
