Sand Shape Level 131 Walkthrough

How to Solve Sand Shape Level 131 — Full Solution
- Fill pink as the full top horizontal I4 on r1c1–r1c4 under the two top Difference triangles.
- Fill yellow as the upper-right 2×2 O on r2c3, r2c4, r3c3, and r3c4, sitting on the Similarity diamond wall.
- Fill green as the left T under pink on r2c1, r2c2, r3c1, and r4c1, left of the L-wall.
- Fill cyan as the bottom-left L on r5c1, r6c1, r7c1, and r7c2.
- Fill blue as the vertical I4 inside the L-wall corridor on r3c2–r6c2, keeping it unlike green across the mid triangle.
- Fill purple as the matching 2×2 O under yellow on r4c3, r4c4, r5c3, and r5c4 so the diamond Similarity card clears.
- Close peach as the bottom-right 2×2 O on r6c3, r6c4, r7c3, and r7c4, then wait for the completion fireworks.
Colors in this level:
Pink, Yellow, Green, Cyan, Blue, Purple, Peach
Common Mistakes to Avoid
- Mirroring pink with a peach top-right square so both upper Difference triangles see matching O shapes.
- Leaving purple as a partial under-diamond dab that fails Similarity against yellow.
- Painting blue as a T or square that matches green across the L-wall triangle.
Quick Tips for Sand Shape Level 131 (spoiler-free)
- Never seat a peach O on the top-right that matches pink across the upper triangles.
- Build purple as a full 2×2 twin of yellow before leaving the diamond.
- Keep blue as a vertical I unlike the left green T across the L-wall triangle.
Board notes 5 details
- Layout
- A cream 4×7 rectangle has a top horizontal wall with two Difference triangles, an L-wall with a third mid triangle between c1 and c2, and a mid-right Similarity diamond on the wall under r3c3–c4.
- Goal
- Partition all 28 cells into seven area-4 tetrominoes so every triangle join stays unlike and the diamond pair matches.
- Opening
- The verified run fills pink as the full top I4 on r1c1–r1c4, then yellow as the upper-right 2×2 O on r2c3–r3c4 sitting on the diamond wall.
- Danger Zone
- A peach top-right 2×2 that mirrors a pink top-left square flashes Difference red X on the upper wall. Partial purple under yellow flashes Similarity red X on the diamond until purple is a full matching O. Green and blue must stay unlike across the L-wall triangle.
- Mechanics
- All regions' area must be 4; Similarity connects same shapes across the mid-right diamond; Difference connects different shapes across the three triangles.

Why does Level 131 flash a red X on the diamond?
The mid-right diamond is a Similarity join between yellow and purple. A partial purple under yellow stays unlike yellow's O until purple is a full matching 2×2.
