Draw a diagonal line starting from the main sand flow channel and extending downwards into the opening of the leftmost cup, creating an enclosed path.
Sand flows into and completely fills the leftmost cup.
From the main sand flow channel (after the turn towards the first cup), draw a curving line to bypass the central obstacle and direct the sand into the opening of the middle cup.
Sand flows into and completely fills the middle cup.
Extend the existing main sand flow channel downwards and then to the right, forming a U-shaped trough that leads directly into the opening of the rightmost cup.
Sand flows into and completely fills the rightmost cup, triggering the 'Level Clear' screen.
Sand misses a cup or gets stuck.
Fix: Ensure all drawn lines form continuous, enclosed channels that guide the sand directly into the cup openings. Avoid gaps or pathways that lead away from the cups.
Evidence Time: N/A
Sand flows out of the play area.
Fix: Make sure all drawn lines are connected to existing structures or form complete enclosures to prevent sand from spilling off-screen.
Evidence Time: N/A
Q: How do I get sand into all three cups?
A: You need to draw a series of interconnected lines that form channels, guiding the falling sand sequentially into each of the three cups.
Q: Can I use the pre-existing lines on the screen?
A: Yes, you must connect your drawn paths to the existing grey structures to effectively channel the sand and solve the puzzle.
Q: What if my drawn line doesn't work?
A: Erase and redraw the line, ensuring it creates a smooth, continuous, and enclosed path that directs the sand precisely into the target cup's opening.
