Sand Loop Level 437 Solution

Step 1: Create a path for the yellow sand and block the blue liquid.

Starting from the upper left where the yellow sand is, draw a continuous line that curves downwards and slightly to the right. This line should form a narrow funnel for the yellow sand, guide it towards the opening mechanism of the green container, and act as a complete barrier to prevent the blue liquid from flowing into the sand's path.

The drawn line is continuous, yellow sand flows freely along its path and enters the green container, and the blue liquid remains separated and contained by the line.

Q: How do I prevent the blue liquid from contaminating the sand?

A: Draw a continuous line that acts as a physical barrier, diverting the blue liquid away from the sand's flow path to the container.

Q: What is the optimal path for the drawn line?

A: The line should start from the top-left sand source, curve downwards and to the right, forming a funnel that leads directly into the green container's opening, while also blocking the blue liquid.
