Overview
Read sand flow on Level 407. Full video walkthrough.
Step-by-step walkthrough
Level 407 has variable sand flow. Calibrate with 3 test drops in drops 1-3. Once calibrated, drop blocks 3 cells diagonally from gaps — spill fills 3 cells. Direct-on-gap drops waste 2 cells of spill radius. Level 407 rewards flow-readers with 40% faster clears. Flow-readers finish in 25 drops; flow-ignorers finish in 40.
💡 Pro tip
3 test drops to read flow. 3-cell diagonal from gaps. Never direct.
