How to Solve Sand Blocks Level 20 — Full Solution

  1. Drag the yellow receiver from the Lane 4 mouth left across the corridor and park it at the Lane 1 mouth beneath the yellow cap while the green stack is evacuated.
  2. Cross G1, the initial bottom green receiver, from Lane 1 to Lane 4 and wait for its green fill and disappearance.
  3. Cross G2 from Lane 1 to Lane 4 and wait for the second green segment to settle.
  4. Cross G3 from Lane 1 to Lane 4 and hold input until the third green receiver vanishes.
  5. Cross G4 from Lane 1 to Lane 4 and let the fourth green segment clear before G5 leaves the stack.
  6. Cross G5 from Lane 1 to Lane 4 and wait for the green column to shorten by one receiver height.
  7. Cross G6 from Lane 1 to Lane 4 and wait until its 100% receiver disappears.
  8. Cross G7 from Lane 1 to Lane 4 and leave the corridor untouched during its settling animation.
  9. Cross G8 from Lane 1 to Lane 4 and verify that it clears before G9 drops to the mouth.
  10. Cross G9 from Lane 1 to Lane 4 and wait for the green sand tail to drop onto it.
  11. Cross G10, the original top green receiver, from Lane 1 to Lane 4 and hold until the green column is empty.
  12. Keep the yellow receiver at the Lane 1 catch position until the exposed yellow cap fills it and the yellow receiver disappears.
  13. Cross B1, the initial bottom blue receiver, from Lane 3 to the bottom of Lane 2 below the red queue; wait only for B2 to drop because blue sand is still blocked.
  14. Cross R1, the initial bottom red receiver, from Lane 2 to the bottom of Lane 3 below the blue queue; wait for R2 to drop.
  15. Cross B2 from Lane 3 to Lane 2, stack it above B1, and wait for B3 to reach the Lane 3 mouth.
  16. Cross R2 from Lane 2 to Lane 3, stack it above R1, and wait for R3 to reach the Lane 2 mouth.
  17. Cross B3 from Lane 3 to Lane 2 and let it drop into the third blue queue position.
  18. Cross R3 from Lane 2 to Lane 3 and let it drop into the third red queue position.
  19. Cross B4 from Lane 3 to Lane 2 and wait for B5 to become the bottom exposed blue receiver.
  20. Cross R4 from Lane 2 to Lane 3 and wait for R5 to become the bottom exposed red receiver.
  21. Cross B5 from Lane 3 to Lane 2 and stack it above B4; blue sand is still blocked by the red source queue.
  22. Cross R5 from Lane 2 to Lane 3 and stack it above R4; red sand is still blocked by B6.
  23. Cross B6, the original top blue receiver, from Lane 3 to Lane 2; Lane 3 now holds only the red delivery queue.
  24. Cross R6 from Lane 2 to Lane 3 and let it join the red queue.
  25. Cross R7 from Lane 2 to Lane 3 and wait for R8 to drop to the Lane 2 mouth.
  26. Cross R8, the original top red receiver, from Lane 2 to Lane 3; Lane 2 now holds only B1-B6 and Lane 3 only R1-R8.
  27. Stop dragging while the red column reaches R1, then wait for R1 to fill and disappear.
  28. Keep the corridor empty while the red sand drops into R2 and clears it.
  29. Wait for R3 to rise to the red fall, fill, and disappear.
  30. Wait for R4 to collect the fourth red segment and clear.
  31. Wait for R5 to collect the fifth red segment and clear.
  32. Wait for R6 to collect the sixth red segment and clear.
  33. Wait for R7 to collect the seventh red segment and clear.
  34. Wait for R8 to collect the red tail; Lane 3 becomes empty after it disappears.
  35. Leave Lane 2 untouched while the blue column reaches B1, then wait for B1 to fill and clear.
  36. Wait for the blue fall to enter B2 and remove the second blue receiver.
  37. Wait for B3 to collect the third blue segment and disappear.
  38. Wait for B4 to collect the fourth blue segment and disappear.
  39. Wait for B5 to collect the fifth blue segment and disappear.
  40. Wait for B6 to collect the blue tail; the board flashes empty and starts confetti after it disappears.

Common Mistakes to Avoid

  • Dragging two receivers into the bottom corridor at once.
  • Sending red twice in succession and trapping the next blue receiver behind Lane 3's mouth.

Quick Tips for Sand Blocks Level 20 (quick clues)

  • Use the initial bottom-to-top receiver numbers; a dropped queue item keeps its original number.
  • Finish each named crossing and settling pause before pulling the next receiver from that source lane.
Board notes 5 details
Layout
Four full-height vertical lanes join only at the bottom corridor. Lane 1 has a yellow cap above ten green one-cell receivers; Lane 2 has a blue column above eight red receivers; Lane 3 has a red column above six blue receivers; Lane 4 has a tall green column above one yellow receiver.
Goal
Cross-deliver every stacked receiver to the lane with matching sand. Each 100% clear lowers its tall column until the last blue segment disappears.
Opening
Number each source stack from its initial bottom: G1-G10 in Lane 1, R1-R8 in Lane 2, and B1-B6 in Lane 3. Move yellow from Lane 4 to the Lane 1 catch position before evacuating G1.
Danger Zone
The bottom corridor has seven staging cells. Move only the named receiver, keep an open cell on its travel side, and push it into the destination lane before exposing the next item in that source stack.
Mechanics
Four vertical queues are cross-paired through a single horizontal corridor. Sand columns descend after each matching one-cell receiver clear, so queue order and settling are the entire puzzle.

Frequently Asked Questions

  • How many receiver crossings does Level 20 use?

    The opening has one yellow shuttle, followed by ten named green deliveries, eight named red deliveries, and six named blue deliveries.

  • Why must every receiver clear before the next move?

    All four queues share one bottom bridge, so an uncleared receiver blocks the next lane-to-lane crossing.
