Sand Shape level guide
Sand Shape Level 29 Walkthrough
Sand Shape Level 29 tiles a 7x8 stepped board with 13 straight three-cell lines. Lock the top perimeter, route separate center columns around the cavities, and save the green bottom run for the final closure.
Board Notes
- Layout
- Use the 7-column by 8-row coordinate box. The board has upper, middle, and lower cavities. The Required Shapes card shows a three-cell straight line, and the verified video uses it both horizontally and vertically.
- Goal
- Use 13 collinear triominoes: `r1c1`-`r3c1`, `r1c3`-`r1c5`, `r2c4`-`r2c6`, `r2c7`-`r4c7`, `r3c2`-`r3c4`, `r3c5`-`r5c5`, `r3c6`-`r5c6`, `r4c1`-`r4c3`, `r5c1`-`r7c1`, `r5c3`-`r7c3`, `r6c4`-`r6c6`, `r7c5`-`r7c7`, and `r8c2`-`r8c4`.
- Opening
- The accepted source run locks the two pink top lines, peach upper line, and lime right line before it fills the center and lower groups.
- Danger Zone
- A red diagonally hatched preview appears late in the source. It is invalid because it bends around a cavity; every accepted shape is three collinear cells.
- Mechanics
- The card shows a horizontal three-cell line. The verified solve also turns it vertical, but never changes the required three-cell count.
Quick Tips for Sand Shape Level 29 (spoiler-free)
- Mark the 13 horizontal or vertical runs before drawing around any cavity.
- Keep the two center vertical runs in separate columns; do not bridge them across the middle opening.
- Save `r8c2`-`r8c4` for last so the two lower vertical runs cannot block it.
How to Solve Sand Shape Level 29 — Full Solution
- Fill the left pink vertical triomino `r1c1`-`r3c1`.
- Fill the top pink horizontal triomino `r1c3`-`r1c5`.
- Fill the peach upper horizontal triomino `r2c4`-`r2c6`.
- Fill the lime right vertical triomino `r2c7`-`r4c7`.
- Fill the upper inner horizontal triomino `r3c2`-`r3c4`.
- Fill the red central vertical triomino `r3c5`-`r5c5`.
- Fill the turquoise central-right vertical triomino `r3c6`-`r5c6`.
- Fill the orange center-left horizontal triomino `r4c1`-`r4c3`.
- Fill the cream left vertical triomino `r5c1`-`r7c1`.
- Fill the blue vertical triomino `r5c3`-`r7c3`.
- Fill the purple lower horizontal triomino `r6c4`-`r6c6`.
- Fill the yellow lower-right horizontal triomino `r7c5`-`r7c7`.
- Finish with the green bottom horizontal triomino `r8c2`-`r8c4`, then wait for `LEVEL COMPLETE`.
Colors in this level:
Pink, Peach, Lime, Purple, Red, Turquoise, Orange, Cream, Blue, Yellow, Green
Common Mistakes to Avoid
- Treating the red-hatched late preview as an accepted move.
- Bending a triomino around a cavity instead of using three collinear cells.
- Filling the bottom `r8c2`-`r8c4` run before the lower vertical columns are separated.
Frequently Asked Questions
Can the three-cell line rotate in Sand Shape Level 29?
Yes. The card depicts a horizontal line, while the verified solution uses both horizontal and vertical three-cell runs.
Why does the late red-hatched preview fail?
It bends around a cavity. Every legal Level 29 shape is exactly three cells in one uninterrupted row or column.
