Sand Shape Level 15 Walkthrough

hard Target: 8 moves 7 colors

Sand Shape Level 15 is a 38-cell stepped board with two fixed holes. Fit six five-cell staircase pentominoes and two 2x2 squares, then finish the lower-right staircase for the completion banner.

Board Notes

Layout: The playable cells fit an 8x8 coordinate box: `r1c4`-`r1c5`; `r2c2`-`r2c7`; `r3c3`-`r3c6`; `r4c2`-`r4c7`; `r5c1`-`r5c2`, `r5c4`-`r5c5`, `r5c7`-`r5c8`; `r6c1`-`r6c8`; `r7c3`-`r7c6`; and `r8c4`-`r8c5`. The holes are `r5c3` and `r5c6`.
Goal: Use the 2x2 squares `r1c4`-`r2c5` and `r5c4`-`r6c5`, plus six staircase pentominoes: orange `r2c2`-`r2c3`, `r3c3`-`r3c4`, `r4c4`; yellow `r2c6`-`r2c7`, `r3c5`-`r3c6`, `r4c5`; green `r4c2`-`r4c3`, `r5c1`-`r5c2`, `r6c1`; turquoise `r4c6`-`r4c7`, `r5c7`-`r5c8`, `r6c8`; purple `r6c2`-`r6c3`, `r7c3`-`r7c4`, `r8c4`; and red `r6c6`-`r6c7`, `r7c5`-`r7c6`, `r8c5`.
Opening: Start with the top red square, then fill the orange and yellow staircases before taking the green and turquoise side regions.
Danger Zone: The two brown holes at `r5c3` and `r5c6` cannot be used. Keep the blue square centered between them and reserve the bottom steps for purple and red.
Mechanics: The Required Shapes card displays a 2x2 square and a five-cell staircase pentomino. The replacement video shows a transient rejected preview, then the accepted eight-region arrangement and a `LEVEL COMPLETE` animation; the rejection is not counted as a solution move.

Quick Tips for Sand Shape Level 15 (spoiler-free)

Mark the two holes first, then treat the blue center square as a fixed four-cell anchor.
Each staircase pentomino advances one column as it descends; do not flatten it into a longer line.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

How to Solve Sand Shape Level 15 — Full Solution

Fill the red top square `r1c4`-`r2c5`.
Fill the orange upper-left staircase: `r2c2`-`r2c3`, `r3c3`-`r3c4`, and `r4c4`.
Fill the yellow upper-right staircase: `r2c6`-`r2c7`, `r3c5`-`r3c6`, and `r4c5`.
Fill the green left staircase: `r4c2`-`r4c3`, `r5c1`-`r5c2`, and `r6c1`.
Fill the turquoise right staircase: `r4c6`-`r4c7`, `r5c7`-`r5c8`, and `r6c8`.
Fill the blue center square `r5c4`-`r6c5`.
Fill the purple lower-left staircase: `r6c2`-`r6c3`, `r7c3`-`r7c4`, and `r8c4`.
Finish with the red lower-right staircase: `r6c6`-`r6c7`, `r7c5`-`r7c6`, and `r8c5`, then wait for `LEVEL COMPLETE`.

Colors in this level:

Red, Orange, Yellow, Green, Turquoise, Blue, Purple

Common Mistakes to Avoid

Using `r5c3` or `r5c6`; both are fixed holes.
Counting the rejected hatched preview as a ninth solution move; the accepted completion uses eight regions.
Merging the two squares with neighboring staircases; both 2x2 blocks must remain intact.
