Sand Shape Level 90 Solution

What You're Up Against

Sand Shape Level 90 challenges you to fill a grid with six distinct colored L-shaped polyominoes (red, yellow, green, blue, purple, pink, and light blue). The core constraint is the “Difference connects different shapes” rule: no two identically colored regions may touch—even diagonally. Each cell contains internal triangles that guide valid connections. A 2-minute-30-second timer adds urgency, and red ‘X’ warnings appear instantly if the rule is violated.

Beating Sand Shape Level 90

1. Start at 2:30. Tap and drag from the top-right corner to fill a 3-cell L-shape red—done by 2:29.
2. From the top-left corner, drag to form a yellow L—complete by 2:26.
3. From the cell directly below the yellow L, drag down then right to build a green L connecting left edge to center—done by 2:24.
4. From the bottom-left of that green shape, drag down and right to complete a blue L in the bottom-left corner—done by 2:23.
5. From the cell adjacent to both blue and green shapes, drag right and up to form a purple region in central-left—done by 2:21.
6. Undo any pink attempt that triggers a red ‘X’ at 2:19; instead, extend purple right to fill central-bottom with pink—done by 2:16.
7. Avoid coloring the central cell blue or purple (triggers ‘X’ at 2:11); instead, from the center-right empty cell, drag down and left—done by 2:09.
8. From the bottom-right isolated cell, drag up and left to seal the bottom-right corner—done by 2:06.
9. Fill the last remaining cell—the top-right of the central cluster—with light blue—done by 2:02.

Doing It Faster

• Prioritize corner and edge L-shapes first—they’re more constrained and reduce later options.
• Use the hidden undo (tap elsewhere) immediately after a red ‘X’ to save time.
• Zoom in to verify triangle alignment before finalizing each drag—it prevents invalid connections.
• Keep mental track of used colors; reusing a color—even unintentionally—breaks the solution.

Where Players Slip Up

• Placing pink too early near the center (e.g., bottom-center) triggers the red ‘X’ at 2:19 due to unintended adjacency.
• Attempting to fill the central cell with blue or purple violates shape uniqueness and triggers ‘X’ at 2:11.
• Ignoring triangle orientation causes shapes to register as disconnected, breaking the “Difference connects different shapes” rule.
• Leaving the top-right central cell for last creates a dead-end—this walkthrough confirms it must be light blue and filled last to avoid isolation.
