How to clear Sand Blocks Level 640
Sand Blocks Level 640 — the video above is the full clear, and the steps below turn it into the pull-order habits that make it repeatable. Watch first, pull second.
- 1
Scout the whole clear first
Expert boards punish early guesses. Watch the entire run above before the first pull, and note where the player pauses — those pauses are the decisions the board forces.
- 2
Clear blockers first, always
One trapped color ends the run. Identify every flow that would wall off another color and take those before anything else.
- 3
Slow down where the run slows
If the recorded player hesitates, your board will need the same care in that spot. Match the caution, not the speed.
- 4
Count colors at the halfway point
Halfway through, list the colors you have not finished. Losing track of one is the most common way these clears fail.
- 5
Bank the easy pits
Take the pits that accept sand quickly and cheaply early on. Every filled pit is space you no longer have to defend.
- 6
Stop pulling when it tightens
If every direction is blocked, the wrong pull has already happened. Reset now rather than spending three moves to confirm it.
- 7
Then clear Level 640 unaided
Close the video and clear Level 640 again from memory. If it holds, the order is yours; if it breaks, rewatch only the section where you slipped.

If Level 640 still will not fall
Opening
Copy the first two pulls from the video before doing anything else. If they land as shown, the rest of the order becomes obvious.
Middle
Compare the middle of the clear with your own board. On Expert boards this is where the routes start to close.
Finish
If more than one color is still open at the end, the order drifted — restart and replay from the middle.
