Sand Loop Level 399 Solution

Step 1: Initiate sand flow into the upper-left collection area.

Tap the top-left sand spout.

Sand starts flowing from the spout, filling the small container.

Step 2: Initiate sand flow into the upper-right collection area.

Tap the top-right sand spout.

Sand starts flowing from the spout, filling the small container.

Step 3: Direct sand from the middle-left section and the central platform to the main vertical channel.

Tap the middle-left sand spout. Immediately after, tap and hold/drag the central rotating gate handle to align its opening with the vertical channel below.

Sand flows from the middle-left spout onto the central platform, then through the rotated gate into the main vertical channel, heading towards the bottom container.

Step 4: Initiate sand flow into the middle-right section and contribute to the main vertical channel.

Tap the middle-right sand spout.

Sand flows from the middle-right spout, over a fixed barrier, and into the main vertical channel.

Step 5: Ensure all sand reaches and fills the large container at the bottom.

No further direct operations; observe the sand flow. All four spouts should be active and the gate correctly aligned.

The large container at the bottom fills completely, and 'LEVEL COMPLETE' appears.

Q: What is the optimal order to open the sand spouts?

A: Based on the video, activate the top-left spout, then the top-right, then the middle-left (while immediately rotating the central gate), and finally the middle-right spout. This sequence ensures a continuous and efficient flow to the final container.

Q: How do I make sand flow from the central platform to the bottom container?

A: You need to tap and rotate the central gate so that its opening aligns with the vertical channel directly below it. This creates a bridge for the sand to fall through.
