Sand Blocks: Drop Puzzle Level 406 Walkthrough
Level 406 starts on a 2:25 timer with dual top pipes, a yellow cover marked 3, a purple cover marked 4, and cyan numbered strips between them. Use the small middle receivers to step the covers down, then bring in the large yellow and green receivers for the late blue/cyan/green cleanup.

How to Solve Sand Blocks Level 406 — Full Solution
- 2:25-2:21 - Open with the central small pieces. The yellow cover drops to badge 2, while cyan strip badges show 3, 4, 2, and 1 across the middle.
- 2:21-2:16 - Keep the cyan and purple pieces moving through the middle. The purple lower cover is down to badge 3 by about 2:16.
- 2:16-2:06 - Clear the next strip/receiver pairings. The yellow cover remains at 2, and the purple cover reaches badge 2 around 2:06.
- 2:06-2:01 - Wait for the remaining cyan strip badges to update before moving a large receiver through the center.
- 2:01-1:46 - Finish the lower-cover phase. By about 1:46 the purple cover is gone/open and the lower board can accept larger pieces.
- 1:46-1:26 - Route the large yellow receiver through the opened lower lane while keeping the right-side white/purple feed clear.
- 1:26-1:06 - Finish the yellow-cover step. By about 1:06 the yellow cover is gone and a large green receiver is exposed on the upper-left.
- 1:06-0:46 - Fill the large green receiver from the left/top path, then keep the cyan L-shaped receiver ready for the exposed middle load.
- 0:46-0:36 - Clear the cyan L and the green horizontal receiver. The cyan L is visibly full around 0:46, and a green horizontal receiver is full around 0:36.
- 0:36-finish - Use the now-open board for the final blue and cyan pieces; no large cover remains, so the last clears are short transfers.
Colors in this level:
Cyan, Yellow, Purple, Green, Blue, Black, White, Pink
Common Mistakes to Avoid
- Dragging the large yellow receiver into the center before the purple cover has opened.
- Ignoring the cyan strip badges; they are the visual signal for when the opening lanes are ready.
- Using the large green receiver before the yellow cover has exposed the upper-left load.
Quick Tips for Sand Blocks Level 406 (quick clues)
- Make the board bigger before moving the large receivers.
- Use the visible cyan strip badge changes as the opening pace marker.
- Save the large green receiver until the yellow cover has opened the upper-left load.
Board notes 5 details
- Layout
- Six columns. The left top pipe shows pink/green layers and the right top pipe shows cyan/dark layers. A large yellow cover marked 3 spans the upper board, and a large purple cover marked 4 spans the lower board. Between them are cyan checkered strips with visible badges such as 4, 5, 1, 3, and 2, plus purple, white, blue, green, yellow, black, and cyan receivers. Side hoppers sit left yellow and right purple at the start.
- Goal
- Use the small central receivers to reduce the strip and cover badges, open the lower board for the large yellow receiver, then remove the yellow cover so the large green receiver and final blue/cyan pieces can clear.
- Opening
- Start with small cyan, green, and purple receivers in the middle. The yellow cover is at badge 2 around 2:21, while the purple cover drops to badge 3 around 2:16 and badge 2 around 2:06.
- Danger Zone
- The large yellow and green receivers are too wide for the opening. Moving either one into the center before the covers release blocks the only route around the cyan numbered strips.
- Mechanics
- Dual top pipes, side hoppers, yellow and purple numbered covers, cyan checkered strip badges, and a late phase built around the large yellow and green receivers.
Frequently Asked Questions
What controls the opening of Level 406?
The small central receivers and cyan strip badges. They step the yellow and purple cover badges down before the large receivers can safely move.
When is the lower board open?
The lower purple cover is gone/open around 1:46, after dropping from 4 to 3 and then 2 during the first half-minute.
When should I use the large green receiver?
After the yellow cover disappears around 1:06. Before that, the green receiver is too large and blocks the center.
