Step 1: Prioritize removing physical barriers
Use the first few conveyor buckets to load any color, aim at the central vertical channel to guide it towards the golden key.
The horizontal barriers on both sides of the lower-middle screen disappear.

Key Moments and Actions
| Time | Scene | Action | Common Error | Confidence |
|---|---|---|---|---|
| 00:01 | Initial state of the level, showing the magic book pattern, with a golden key at the bottom center and locked barriers on both sides. | Start pouring white and red sand to fill the book pages and some smoke lines. | Failing to trigger the key and directly pouring a large amount of sand, causing sand to accumulate above the barriers. | 95% |
| 00:30 | Sand flows down and successfully touches the golden key icon at the bottom center. | Observe the mechanical latches (blue and pink) on both sides opening, making the path completely clear. | Sand flow not falling vertically and missing the key trigger point. | 100% |
| 03:12 | Pattern progress is close to 99%, with only book page seams and background edge gaps remaining. | Precisely inject purple and white sand sources for the final completion. | Operating too quickly in late-stage multi-color mixed areas leading to color contamination. | 90% |
Step-by-Step Walkthrough
Step 2: Outline the book and smoke
Use white to fill book pages, yellow to fill book edges and smoke edges, and inject a large amount of purple for the magical background.
Purple and white percentages above the pattern reach over 60%.
Step 3: Fill the core colorful smoke
Alternately tap cyan-blue, red, and yellow sand balls to fill the swirling smoke details rising from the book.
All lines are clearly defined, and the puzzle completion reaches 100%.
Common Failures and Fixes
Barriers obstructing and causing sand overflow
Fix: The golden key must be unlocked within the first 30 seconds, otherwise the bottom area of the pattern cannot be filled.
Evidence Time: 00:15
Multi-color smoke mixing
Fix: Smoke lines are extremely thin; you must 'tap and release' when the bucket is precisely aimed at the drop point, strictly avoiding long presses to pour sand.
Evidence Time: 01:45
Variant Notes
In some versions, the golden key might move sideways
Adaptation: Observe the physical dynamics of the bottom grids and adjust the sand drop point according to the direction of gravity.
Quick FAQ
Q: What does the number '4' in the middle grid mean?
A: It means that the physical container at that fixed position can hold/divert sand up to 4 times, after which its path might change.
Q: The purple background proportion is large, is there enough sand?
A: The purple sand source is very abundant; it is recommended to prioritize the accuracy of complex lines (red, cyan, yellow).
