Step 1: Complete the base and background filling
Click the yellow sand ball, prioritizing filling the horizon at the bottom of the screen and the blank spaces on the sides.
The sand-colored area progress bar below the pattern is filled.

The challenge objective is three stacked books. The core difficulty lies in switching multiple color blocks for the book spines and the complex physical paths of the pipes at the bottom, requiring precise control of the sand flow rhythm.
| Time | Scene | Action | Common Error | Confidence |
|---|---|---|---|---|
| 00:01 | Initial level layout, showing the target pattern of three book spines in red, yellow, and green. | Start pouring a large area of background yellow sand into the conveyor bucket. | Ignoring the narrow path at the bottom leads to sand overflow. | 90% |
| 01:28 | Fill in the book spine details through the narrow U-shaped channel at the bottom. | Use multiple bucket positions to load red, green, and yellow sand separately, alternating through the holes. | Overlapping bucket positions lead to multiple colors mixing in the same book spine area. | 85% |
| 03:10 | Fill the white areas of the book pages. | Precisely inject white sand to fill the side layers of the three books. | The white sand source is very limited; accidental clicks will prevent level completion. | 95% |
Click the yellow sand ball, prioritizing filling the horizon at the bottom of the screen and the blank spaces on the sides.
The sand-colored area progress bar below the pattern is filled.
Following a bottom-up order (yellow book, red book, green book), inject the corresponding colors into the bucket through the narrow channel in the middle.
The three color blocks of the book spine are fully displayed.
Finally, fill with white sand to outline the texture of the book pages.
The cross-sections of the three books appear white, and the pattern is complete.
Book spine color misalignment
Fix: Observe the spacing of the conveyor belt buckets, ensuring the bucket is precisely aligned with the correct color sand drop hole before injecting.
Evidence Time: 01:35
Narrow path blockage
Fix: Do not continuously and rapidly click the same sand ball to avoid sand accumulation at the funnel, which can cause abnormal physical collisions.
Evidence Time: 00:45
Randomized sand source positions
Adaptation: In this video, the red and green sand sources are distributed on both sides at the bottom; during operation, pay attention to switching the tapping frequency between left and right hands.
Q: Why does the player in the video load two colors into one bucket?
A: At the junction of the book spine and background, this method allows for more efficient use of a single transfer cycle, reducing waiting time.
Q: What is the purpose of the U-shaped tube in the middle?
A: It acts as a gravity funnel, restricting the sand flow speed and requiring players to anticipate and tap half a second in advance.
