Featured Puzzle: L.I.T.S. #4 – Double L.I.T.S.

Today, we have a “couples” variant of L.I.T.S. Normally, you need to shade 4 cells in each region to place a single tetromino. In Double L.I.T.S., you must shade a total of 8 cells, to place two tetrominoes in each region.

Shade eight cells in each region to place exactly two L, I, T, or S-tetrominoes there.

  • Shaded cells must form an orthogonally contiguous area.
  • Each tetromino may be rotated or reflected.
  • Tetrominoes of the same type may not share any part of an edge. Touching diagonally is allowed.
  • Shaded cells may not cover any 2×2 area.
  • Tetrominoes within the same region may be the same or different shapes.
  • Tetrominoes in the same region may not share any part of an edge, regardless of type. Again, diagonal touching is permitted.
