Sand Shape level guide
Sand Shape Level 150 Walkthrough
Sand Shape Level 150 is the area-4 wall-maze capstone. Lock the left pink rail and peach/green matching L pair, stripe yellow, fill the top cyan/blue/purple/maroon band, thread orange/lime/dark green/mint through the right maze, seat indigo, then close violet, rose, and brown on the bottom pocket.

How to Solve Sand Shape Level 150 — Full Solution
- Fill pink as the far-left vertical tetromino rail from the top edge down the left wall (exactly 4 cells), stopping above the yellow corridor.
- Fill peach as the centre-left L tetromino in the pocket right of pink’s lower half, under the left diamond wall.
- Fill yellow as the horizontal tetromino under pink/peach across the mid-left corridor (4 cells).
- Fill green as the full left L tetromino beside pink and above peach so the left diamond joins matching L shapes; grow past any partial-fill Similarity X on a short green strip.
- Fill cyan as the top mid tetromino right of green along the top edge into the upper wall bay.
- Fill blue as the centre snake/T tetromino under cyan, threading the upper-centre wall pocket toward maroon’s bay.
- Fill purple as the top-right tetromino in the upper-right corner bay.
- Fill maroon as the right-upper tetromino under purple’s right edge, unlike purple across the upper-right triangle.
- Fill orange as the mid-right horizontal/S tetromino under blue and left of lime’s future column.
- Fill lime as the far-right mid tetromino along the outer right wall under maroon.
- Fill dark green as the lower-right vertical tetromino under orange/lime toward the bottom-right triangle.
- Fill mint as the lower mid-right tetromino left of dark green under orange.
- Fill indigo as the centre-lower tetromino under yellow/orange on the mid spine; finish the full 4-cell silhouette if a centre diamond flashes Similarity red X.
- Fill violet as the bottom mid-left tetromino under yellow’s right end into the lower-left pocket.
- Fill rose as the bottom-left L tetromino under yellow’s left end so the lower-left diamond joins matching shapes with violet; grow past any partial-fill Similarity X.
- Close brown as the bottom-left foot tetromino under rose/violet into the last cream cells, then verify every diamond pair matches, every triangle pair differs, and every region is area 4.
Colors in this level:
Pink, Peach, Yellow, Green, Cyan, Blue, Purple, Maroon, Orange, Lime, Dark green, Mint, Indigo, Violet, Rose, Brown
Common Mistakes to Avoid
- Leaving green as a short strip beside pink so the left diamond fails Similarity against peach’s L.
- Painting any region with area ≠ 4 (3-cell stub or 5+ flood).
- Merging rose into the left pink rail so the bottom pocket loses its matching diamond pair with violet.
Quick Tips for Sand Shape Level 150 (spoiler-free)
- Grow green to the full L that matches peach before leaving the left rail.
- Keep every stroke at exactly four cells — short stubs and 5+ floods fail the area card.
- Treat rose as a second pink-family region, not an extension of the left rail.
Board notes 5 details
- Layout
- An ~8×8 cream rectangle is carved by brown wall stubs into a maze of corridors and pockets, with dense diamond Similarity and triangle Difference markers on the left rail, mid spine, right corridor, and bottom pocket. Region map (paint order): pink left rail; peach centre-left L; yellow mid-left bar; green left L; cyan top mid; blue centre snake; purple top-right; maroon right upper; orange mid-right; lime far-right; dark green lower-right; mint lower mid-right; indigo centre-lower; violet bottom mid-left; rose bottom-left L; brown bottom foot.
- Goal
- Tile every cream cell with area-4 tetrominoes so every diamond-marked join pairs matching silhouettes and every triangle-marked join pairs unlike silhouettes.
- Opening
- The verified run fills pink as the far-left vertical tetromino rail, peach as the centre-left L pocket under the left diamond wall, then yellow as the horizontal tetromino under pink/peach.
- Danger Zone
- A short green strip beside pink flashes Similarity red X against peach until green is the full matching L; indigo and the rose/violet bottom pocket also show mid-run Similarity X until both diamond partners are full 4-cell silhouettes; any region not exactly four cells fails the area card.
- Mechanics
- All regions' area must be 4; Similarity connects same shapes; Difference connects different shapes across the wall maze. Sixteen tetrominoes pack the board; no gems.
Frequently Asked Questions
What rules does Sand Shape Level 150 use?
All regions must have area 4, Similarity diamonds require matching tetromino silhouettes, and Difference triangles require unlike silhouettes. Sixteen tetrominoes pack the wall maze.
What is the safest opening for Sand Shape Level 150?
Fill pink on the far-left rail, peach as the centre-left L, yellow as the mid-left bar, then green as the full matching L across the left diamond before the top corridor.
Why does Level 150 flash Similarity red X cards?
Partial regions look unlike their diamond partners. The video shows temporary X states on partial green vs peach, on the indigo mid-spine, and on the rose/violet bottom pocket until both sides are full 4-cell silhouettes.
How many colour regions does Level 150 need?
Sixteen solution placements from the left rail through the right maze and bottom pocket. Reused hues (pink/rose, green/dark green/mint, purple/violet, peach/brown) always refer to different regions by position.
