Sand Shape Level 13 Walkthrough
Sand Shape Level 13 is a 34-cell 6x6 board with two fixed holes. Use six matching five-cell L pentominoes and one 2x2 square to route around the two holes.
Board Notes
- Layout
- The board is a 6x6 grid with fixed holes at `r2c2` and `r5c5`. Internal wall corners at the upper-right and center also mark the intended region boundaries.
- Goal
- Fill six L pentominoes and one square: red `r1c1`-`r1c3`, `r2c1`, `r3c1`; green `r1c4`-`r1c6`, `r2c6`, `r3c6`; orange `r4c1`, `r5c1`, `r6c1`-`r6c3`; yellow `r4c6`, `r5c6`, `r6c4`-`r6c6`; purple `r3c2`, `r4c2`, `r5c2`-`r5c4`; blue `r2c3`, `r3c3`, `r4c3`-`r4c5`; and turquoise square `r2c4`-`r3c5`.
- Opening
- Start with the red upper-left L, then use the lower-left orange L and lower-right yellow L to anchor the two sides of the board.
- Danger Zone
- Never fill `r2c2` or `r5c5`; those holes are fixed. The center turquoise square must stay inside `r2c4`-`r3c5` rather than absorbing cells from the blue L.
- Mechanics
- The Required Shapes card displays a five-cell L pentomino and a 2x2 square. The source confirms seven accepted regions and a completion transition, with no visible penalty signal.
Quick Tips for Sand Shape Level 13 (spoiler-free)
- Mark both holes before solving, then match each L pentomino to a board corner or wall turn.
- The single square is the turquoise center block; every other colored region has five cells.
- Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.
