Theme: Logical

Author/Opus: This is the 235th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Variation of LITS rules. Every region here is a lie: while exactly four cells must be shaded in each bold region, they do not form an L, I, T, or S tetromino. (Note: the other rules still apply. There must be a single connected group of shaded cells, divisible into L, I, T, and S tetrominoes so that no two identical tetrominoes touch and no 2×2 block of cells is completely shaded.)

Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma.

Time Standards (highlight to view): Grandmaster = 5:00, Master = 10:30, Expert = 21:00
