Sand Shape Level 138 Solution

Level Overview

This level, Sand Shape Level 138, presents a grid partitioning puzzle on a 6x6 board. Your primary objectives are to divide the entire grid into distinct regions. Each of these regions must have an area of exactly 4 grid cells. Additionally, every single region you create must contain precisely one green heart gem. The puzzle starts with a 3-minute timer, requiring efficient planning and execution to complete all regions before time runs out. The overall strategy involves identifying each gem and then carefully drawing lines to form 4-cell shapes around them, ensuring no overlap and that the entire grid is eventually filled.

Step-by-Step Walkthrough

1. Begin by observing the entire 6x6 grid and the positions of the 9 green heart gems. You will need to create 9 regions, each 4 cells in area.
2. Start in the bottom-left corner. Identify the gem at Row 5, Column 1. Tap to draw lines around cells (R4,C1), (R5,C1), (R6,C1), and (R6,C2) to form a 4-cell region. This area will be highlighted orange.
3. Move up to the gem at Row 3, Column 1. Form a region using cells (R3,C1), (R3,C2), (R4,C2), and (R5,C2). This will highlight as a light orange region.
4. Next, focus on the bottom-right gem at Row 6, Column 4. Create a region using cells (R5,C3), (R5,C4), (R6,C3), and (R6,C4). This area will turn yellow.
5. Proceed to the gem at Row 4, Column 3, located in the middle-right section of the grid. Enclose cells (R3,C3), (R3,C4), (R4,C3), and (R4,C4) to form a light green region.
6. Now, address the bottom-middle gem at Row 6, Column 6. Draw lines to define the region including cells (R5,C5), (R5,C6), (R6,C5), and (R6,C6). This will become a light blue region.
7. Shift your attention to the gem at Row 3, Column 6, in the upper-right middle. Form a region from cells (R3,C5), (R3,C6), (R4,C5), and (R4,C6). This area will be colored purple.
8. Go to the top-right corner. The gem is at Row 1, Column 6. Create a region using cells (R1,C5), (R1,C6), (R2,C5), and (R2,C6). This will be another yellow region.
9. Next, tackle the top-middle gem at Row 2, Column 3. Encompass cells (R1,C3), (R1,C4), (R2,C3), and (R2,C4) to form a dark green region.
10. Finally, complete the puzzle by addressing the remaining gem at Row 1, Column 1 in the top-left corner. Create the final region using cells (R1,C1), (R1,C2), (R2,C1), and (R2,C2). This area will highlight light green, successfully completing Level 138.

Pro Tips

• Prioritize gems in corners or along existing grid boundaries first, as these often have fewer valid 4-cell shape configurations.
• Visualize common 4-cell tetromino shapes (like 2x2 squares, 1x4 lines, or L-shapes) that can enclose a single gem.
• Always double-check that each proposed region is exactly 4 cells in area and contains only one gem before finalizing its boundaries.
• Work systematically across the board. For example, move from left to right or top to bottom, making sure to fill all spaces.
• Keep an eye on the timer, but avoid rushing. Precise movements are more important than speed. The 3-minute timer provides ample time for careful consideration.

Common Mistakes

• Creating regions that are not exactly 4 cells large. Each region must strictly adhere to the 'area must be 4' rule.
• Enclosing more than one gem or no gems at all within a single region. Remember, each region needs exactly one green heart gem.
• Leaving small, isolated gaps of unassigned cells on the board that cannot be formed into a valid 4-cell region, effectively blocking progress.
• Attempting to draw overly complex shapes when simpler, standard tetromino shapes often fit perfectly.
