Sand Shape Level 90 Solution

Level Overview

This level requires players to fill the entire grid with distinct colored polyomino shapes. The core challenge involves adhering to the 'Difference connects different shapes' rule, which governs how different colored regions can be adjacent to one another. Players must strategically connect cells containing triangles to form contiguous blocks of color, ensuring no rule violations occur and the entire board is covered within the given time limit. The 'Required Shapes' at the top likely serve as an abstract completion goal for the number or type of colored regions.

Step-by-Step Walkthrough

1. Start the level with the timer at 2 minutes and 30 seconds.
2. Tap the top-right corner cell and drag to color the L-shaped region (comprising three cells) red. This completes the first red segment by 02:29.
3. Tap the top-left corner cell and drag to color the L-shaped region (comprising three cells) yellow. This segment is completed by 02:26.
4. From the cell directly below the top-left yellow L-shape, drag downwards and then right to create a green L-shaped region. This connects cells from the left edge towards the center of the board, completed by 02:24.
5. Continue from the bottom-left of the newly formed green shape, dragging to form a blue L-shaped region downwards and right, filling the bottom-left corner area by 02:23.
6. From the cell adjacent to both the blue and green shapes, drag to form a purple region moving right and slightly up, filling the central-left area. This step is completed by 02:21.
7. Attempt to fill a region near the bottom-center with a pink color. A red 'X' will appear over the 'Difference connects different shapes' rule at 02:19, indicating an invalid move.
8. Undo the last pink coloring attempt. The red 'X' will disappear, restoring the board state from before the incorrect move (by 02:18).
9. From the purple region, extend a pink shape to the right, filling the central-bottom cell. This corrected move satisfies the rule and is completed by 02:16.
10. Attempt to fill a small central cell with a new color (likely blue or purple). A red 'X' will appear again at 02:11, signifying another rule violation.
11. Undo the last coloring attempt. The red 'X' will disappear, reverting the board state (by 02:10).
12. From the center-right empty cell, drag to form a purple shape downwards and left, effectively filling the remaining central-right cells (by 02:09).
13. From the bottom-right isolated cell, drag to form a green shape upwards and left, completely filling the bottom-right corner of the puzzle area (by 02:06).
14. Fill the last remaining empty cell at the top-right of the central cluster with a light blue color (by 02:02).
15. The puzzle is now complete, with the entire board filled with distinct colored polyomino shapes, triggering a celebratory animation.

Pro Tips

• Always pay close attention to the 'Difference connects different shapes' rule. If a red 'X' appears, immediately undo your last action to prevent further issues.
• Plan your shape placement carefully. Consider starting with corner or edge regions and working your way inward to avoid trapping small, difficult-to-fill areas.
• The triangles within each cell act as connection points. Ensure you are dragging to adjacent cells that contain these triangles to form valid shapes.
• Utilize the implicit undo feature when you make a mistake. There's no visible explicit undo button, but the game allows you to correct rule-breaking moves.
• Keep an eye on the timer. While this level shows ample time, later levels may require faster decision-making.

Common Mistakes

• Failing to observe the 'Difference connects different shapes' rule, which results in a red 'X' and requires an undo action.
• Creating shapes that unintentionally isolate other cells, making it impossible to fill them later according to the rules.
• Rushing through the level and making hasty connections that lead to rule violations or dead ends.
• Not utilizing the full extent of available moves from a starting point, potentially leaving more complex regions to fill at the end.
