How to clear Sand Blocks Level 639
Sand Blocks Level 639 walkthrough: a full video solution for this Expert board, plus a written breakdown of the pull order that clears it. Watch the run above, then apply the steps below to your own board.
- 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
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.
- 3
Hold the whole order in mind
Expert boards cannot be recovered by feel. Build the full order from the run above before the first pull, and follow it even when another move looks tempting.
- 4
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.
- 5
Re-watch the middle
The middle of the run is where Expert boards turn. Watch that section twice; most failed attempts break exactly there.
- 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 639 unaided
Close the video and clear Level 639 again from memory. If it holds, the order is yours; if it breaks, rewatch only the section where you slipped.

Pro tips for Sand Blocks Level 639
Two clears, not one
One guided clear is not mastery. Run it again with the video closed before you call the level done.
Order beats instinct
Build the full order from the video before pulling anything. Expert boards do not forgive an improvised move.
Level 639 checkpoint
Level 639 is an Expert board and the 390th of 391 in that tier. If your attempt keeps breaking, pause the run at the opening and compare that frame with your board — the difference tells you which pull you mis-ordered.
If Level 639 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.
