Sand Loop Level 339 Solution

Step 1: Guide the initial sand flow into the main loop structure.

Draw a diagonal line from the sand source (top-left) downwards and to the right, aiming for the entrance of the loop.

Sand begins to flow along the drawn line and enters the loop's opening.

Step 2: Ensure sand travels through the entire loop path.

Draw a short horizontal line across the gap at the bottom-right section of the loop.

Sand continues flowing around the inside of the loop path, rather than falling out of the gap.

Step 3: Fill the left container to a sufficient level.

Allow sand exiting the loop to fall naturally into the left container. Wait until it is approximately two-thirds full.

The left container begins to fill, reaching a visible level of completion.

Step 4: Redirect the remaining sand to fill the right container.

Draw a diagonal line starting from the loop's exit point (bottom-left) and angling downwards and to the right, creating a path directly into the right container. This line should be drawn *after* the left container has received enough sand.

The sand flow diverts from its previous path, flows along the new line, and begins to enter the right container.

Q: How do I make the sand go into both containers?

A: You need to first direct the sand into the loop and let it fill the left container partially, then draw a third line to redirect the rest of the sand to the right container.

Q: What is the trick to the loop structure?

A: The loop has a small gap. You must draw a line to close this gap, forcing the sand to complete the full circuit of the loop.

Q: When should I draw the last line to redirect sand?

A: Draw the last line after the left container has received approximately two-thirds of its required sand. This ensures both containers are adequately filled.
