This level's challenge is the snake and branch pattern; the core difficulty lies in the red and pink dual-color key unlocking mechanism at the bottom. The key is to precisely pour sand to trigger the mechanism first and clear the path.
| Time | Scene | Action | Common Error | Confidence |
|---|---|---|---|---|
| 00:01 | Level starts, showing the target pattern of a snake coiled around a branch, with red and pink mechanical locks in the middle. | Observe the sand source distribution and prepare to guide the sand flow through the corresponding keyholes. | Blindly filling the yellow main body leads to sand accumulation at the top, preventing it from entering the outline. | 95% |
| 00:23 | Sand flow successfully touches the red key icon at the bottom. | Observe the red gate in the middle opening. | Insufficient sand poured results in the key not being fully activated. | 100% |
| 00:34 | Sand flow successfully touches the pink key icon in the middle. | Pink gate opens, and the entire physical path of the level is cleared. | Switching the main color too early causes the pink keyhole to be missed. | 100% |
| 01:05 | Entering the large-area background color (blue, green) filling phase. | Multiple buckets cooperatively inject environmental colors, reserving space for the snake's body. | Background color encroaches on the snake's body outline (color contamination). | 85% |
Click on the corresponding red and pink sand balls below, load 1-2 buckets of sand into each, and guide them towards the respective key switches.
The red and pink horizontal bar obstacles in the middle of the screen disappear.
Use brown sand to fill the branches, and blue and green to fill the sky and leaf areas.
The area above the pattern, excluding the snake's body, largely becomes solid color.
Precisely inject yellow and orange sand sources, performing the final saturated filling according to the snake's texture.
All of the snake's spots and outline light up, and the system determines 'Level Complete'.
Path blockage leading to overflow
Fix: Before the gates are opened, strictly avoid injecting large amounts of main yellow sand, otherwise it will cause severe sand accumulation and waste.
Evidence Time: 00:05
Incorrect color mixing
Fix: There are many intersections between the snake's body and the background; observe the conveyor belt rhythm to ensure the purity of single colors.
Evidence Time: 01:28
In some versions, the key icon and gate color may not perfectly match.
Adaptation: Prioritize trying the key closer to the sand inlet; it is usually the switch for the first layer of the path.
Q: What does the number '25' in the bottom left corner represent?
A: That is the total stock of red sand balls. This level requires it to unlock the red lock; the remaining amount is quite sufficient, but it's recommended not to use it all at once.
Q: What if the snake's eyes are difficult to fill?
A: Those are tiny black/dark pixels; you need to wait until the conveyor bucket is perfectly vertically aligned with the central gap, then quickly 'tap-pour'.
