How to clear Sand Blocks Level 638

This is the Sand Blocks Level 638 route: watch the run above for the real clear, then work through the steps below in order. They are the principles that decide pull order on an Expert board, so they carry over to your own attempt.

  1. 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. 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. 3

    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.

  4. 4

    Repeat it without the video

    Clear it a second time with the video closed. On Expert boards, one guided clear is not yet proof that the order is yours.

  5. 5

    Never salvage a tangled board

    Once the sand is sitting wrong, restarting is faster than untangling. Expert boards punish cleanup more than any other tier.

  6. 6

    Treat the full clear as the spec

    The run above is the reference, not a suggestion. Where your board differs from it, copy the video's next decision.

  7. 7

    Then clear Level 638 unaided

    Close the video and clear Level 638 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 638

One trapped color ends it

Identify every flow that could wall off another color and clear those before you take anything comfortable.

Rewatch the middle

Expert boards usually turn in the middle of the run. That section is worth a second look before you attempt it.

Level 638 checkpoint

Level 638 is an Expert board and the 389th 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 638 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.
