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.
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.
Board notes 5 details
- 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.
