Rules: The challenge is to shade four connected cells in each shape, subject to the following rules:
- No two of the same tetrominos, including rotations / reflections are allowed to touch.
- All shaded cells must connect upon completion.
- No 2x2 area of shaded cells is allowed.
- Some shapes exit the grid and re-enter via pathways. These areas are considered the same shape but no part of the tetromino can be on the pathway.
