Sand Blocks: Drop Puzzle Level 405 Walkthrough
Level 405 starts on a 3:00 timer with a purple cover marked 3 above a yellow cover marked 4. Clear the yellow cover first, then reduce the purple cover and open the central chamber before the white top feed and changing side feed run the late cyan, black, green, red, orange, magenta, and white cleanup.

How to Solve Sand Blocks Level 405 — Full Solution
- 3:00-2:58 - Begin with the yellow receivers. The yellow cover drops to badge 3 almost immediately while the purple top cover remains at 3.
- 2:58-2:48 - Keep yellow pieces under the right-side sand. The yellow cover shows badge 2 around 2:53 and badge 1 around 2:48.
- 2:48-2:38 - Finish the yellow cover and wait through the visible strip/counter updates. The lower checkered row continues to count down while the upper purple cover stays at 3.
- 2:38-2:23 - Use the exposed lower board to clear the first green, red, blue, black, and white receivers without sealing the center.
- 2:23-2:03 - Work the pieces that reduce the purple cover. By about 2:03 the purple cover is at badge 1 and the central chamber is ready to open.
- 2:03-1:43 - Let the purple cover disappear, then move L-shaped receivers through the open middle instead of around the edges.
- 1:43-1:23 - Start the white top-feed phase. Use the open center for white and black receivers, and keep cyan/green pieces near the right-side lane for the next color changes.
- 1:23-1:03 - Route magenta, red, green, and orange pieces through the center as the side feed changes. Do not leave a horizontal bar across c3-c5 unless it is actively filling.
- 1:03-0:43 - With the board thinned, lift the orange and red receivers into the right side and keep the cyan L available for the final top-feed loads.
- 0:43-0:23 - Clear the last colored receivers. A white receiver is still filling around 0:23, so hold the remaining cyan and black pieces clear of the top pipe.
- 0:23-0:13 - Finish the cyan L and black pieces in the open center; the level clears around 0:13.
Colors in this level:
White, Purple, Yellow, Green, Red, Blue, Black, Orange, Magenta, Cyan
Common Mistakes to Avoid
- Parking the white L in the center before the yellow cover has finished.
- Letting the long green bar seal the gold-outlined chamber while the purple cover is still marked.
- Skipping the settle time after cover changes; the next receiver often needs the newly opened center.
Quick Tips for Sand Blocks Level 405 (quick clues)
- Treat the first half as gate opening: yellow cover first, purple cover second.
- Keep the gold-outlined center clear until the purple cover is nearly gone.
- After the central chamber opens, route L-shaped receivers through the middle instead of along the edges.
Board notes 5 details
- Layout
- Six columns. A white top pipe sits above a huge purple cover marked 3, with a huge yellow cover marked 4 underneath. The lower half contains yellow receivers, a white L on the left, purple and black bars, a blue square, green square/bar pieces, a red bar, and right-side yellow sand. Several checkered pink strips in the lower middle show changing numbers such as 15, 14, 13, and 12 during the opening.
- Goal
- Drain the yellow layer enough to remove the yellow cover, reduce the purple cover, open the central gold-outlined chamber, and then use that center lane for the white top-feed finish.
- Opening
- Use yellow receivers under the right-side yellow sand. The yellow cover is marked 3 around 2:58, 2 around 2:53, and 1 around 2:48 before it opens.
- Danger Zone
- The center lane is not safe storage at the start. A long green bar, white L, or red bar across the gold-outlined opening can trap the second phase while the purple cover is still counting down.
- Mechanics
- Two large numbered covers gate the board. Lower checkered strips display visible badge changes, and the central chamber opens only after the yellow and purple cover sequence.
Frequently Asked Questions
Which cover opens first in Level 405?
The yellow cover. It drops through badges 3, 2, and 1 by about 2:48 and is gone/open around 2:38.
When does the purple cover disappear?
It is still visible through the first half, reaches badge 1 around 2:03, and is gone by about 1:43.
Why should I keep the center clear?
The center is the only efficient route once the gold-outlined chamber opens. Blocking it early traps L-shaped receivers and wastes the late white-feed window.
