Step 1: Rotate the L-shaped block directly to the right of the sand dispenser exit to direct sand right and down.
Tap the L-shaped block (located at approximate grid position 4th column, 2nd row from top) three times to rotate it to the 'right and down' orientation. (Initial state: right-down, 1st tap: left-down, 2nd tap: right-up, 3rd tap: right-down).
The block's opening faces right and down.
Step 2: Rotate the L-shaped block below the previous one to direct sand left and up.
Tap the L-shaped block (located at approximate grid position 4th column, 3rd row from top) once to rotate it to the 'left and up' orientation. (Initial state: right-up, 1st tap: left-up).
The block's opening faces left and up.
Step 3: Rotate the L-shaped block at the bottom right, near the goal, to direct sand right and down.
Tap the L-shaped block (located at approximate grid position 7th column, 7th row from top) twice to rotate it to the 'right and down' orientation. (Initial state: down-left, 1st tap: right-up, 2nd tap: right-down).
The block's opening faces right and down.
Step 4: Rotate the U-shaped block at the top right to direct sand downwards.
Tap the U-shaped block (located at approximate grid position 7th column, 1st row from top) once to rotate it to the 'downwards' orientation. (Initial state: upwards, 1st tap: downwards).
The block's opening faces downwards.
Step 5: Rotate the U-shaped block at the top left to direct sand downwards.
Tap the U-shaped block (located at approximate grid position 1st column, 1st row from top) once to rotate it to the 'downwards' orientation. (Initial state: upwards, 1st tap: downwards).
The block's opening faces downwards.
Step 6: Place a rectangular block in the gap below the top-right U-shaped block.
Tap the empty space at approximate grid position 7th column, 2nd row from top. A rectangular block will appear.
A rectangular block fills the gap, creating a continuous path segment.
Step 7: Place a rectangular block in the gap next to the goal, below the L-shaped block rotated in step 3.
Tap the empty space at approximate grid position 7th column, 8th row from top. A rectangular block will appear.
A rectangular block fills the gap, guiding sand into the goal.
Step 8: Rotate the U-shaped block at the bottom left to direct sand upwards.
Tap the U-shaped block (located at approximate grid position 2nd column, 7th row from top) once to rotate it to the 'upwards' orientation. (Initial state: downwards, 1st tap: upwards).
The block's opening faces upwards.
Step 9: Rotate the U-shaped block near the bottom center (above the goal) to direct sand upwards.
Tap the U-shaped block (located at approximate grid position 5th column, 7th row from top) once to rotate it to the 'upwards' orientation. (Initial state: downwards, 1st tap: upwards).
The block's opening faces upwards.
Step 10: Start the sand flow simulation.
Tap the triangular 'play' button icon at the bottom of the screen.
Sand starts pouring from the dispenser and flows through the constructed path.
