Sand Blocks: Drop Puzzle Level 424 Walkthrough
Level 424 starts with a three-count cyan shutter beneath a compact green/cyan pocket. Early upper clears quickly reduce it to 1, and the final clear opens the board to reveal a purple lock marked 3. Preserve the left key lanes and finish with the final purple load.

How to Solve Sand Blocks Level 424 — Full Solution
- Start by filling the green/cyan receiver in the upper-left catch footprint around r1c1-c2. Let it clear before moving the orange bar; this is one of the early shutter-count clears.
- Move the orange horizontal receiver to r1c3-c4, the pink square to r1c5, and the green square to r1c6. Keep the tall white key receiver parked at r2-r4c7 so it does not block the right shelf.
- Use the blue and yellow receivers in the second row: stage the blue square at r2c2 and the yellow bar at r2c4-c5. These clears bring the cyan shutter down to its last count.
- Before that last clear, move the long brown receiver to the left shelf r3c1-c3 and the cyan bar to r5c5-c7. Leave the central throat above the shutter open for the final clear.
- Wait for the cyan shutter to disappear. Do not drag the purple locked receiver; it is a gated piece, not an ordinary sand receiver.
- Fill the reachable white key receivers around r4c2 and r6c2-c3, then move the yellow vertical into the lower-middle landing column around r6-r8c4. Let each key receiver reach 100%; each key flies automatically to the purple lock marked 3.
- Keep the striped purple vertical in its lower-middle lane and use the open right side for the white key receiver at c7 and the orange side-feed receiver. This prevents the brown bar from sealing the only route around the lock.
- In the late phase, finish the remaining yellow and white pieces on the upper and right shelves. When the last bottom-right key receiver fills, wait for its key animation instead of starting another drag.
- Once the purple lock has taken all three keys, move the last yellow bar to the right shelf around r5-r6,c5-c7 and leave the purple receiver's footprint clear.
- When the pipe turns purple, place the purple receiver under the upper-left outlet around r1-r2,c1-c3. Its clear finishes the board.
Colors in this level:
Green, Cyan, Orange, Pink, Yellow, White, Blue, Brown, Purple
Common Mistakes to Avoid
- Treating the cyan shutter as a tank or waiting for it to change by time. Its badge drops only after receiver clears.
- Parking the long brown bar or a white key receiver across the central throat and sealing the route around the purple lock.
- Interrupting a receiver that is already filling from a side pipe.
Quick Tips for Sand Blocks Level 424 (quick clues)
- Clear the compact upper pocket before moving the large brown bar; it is the fastest way to reduce the cyan shutter.
- Once the shutter opens, treat the purple lock as a keep-clear zone and fill key-marked receivers from the outside inward.
- Do not pull a key receiver away while its percentage is rising; its key flies to the lock only after it clears.
Board notes 5 details
- Layout
- A seven-column board. The upper-left well starts green/cyan. Visible receivers include an orange bar at r1c3-c4, pink square at r1c5, green square at r1c6, orange and blue squares at r2c1-c2, pink square at r2c3, yellow bar at r2c4-c5, tall white key-marked receiver at r2-r4c7, brown bar at r3c1-c3, green square at r3c5, blue vertical at r4c1, yellow bar at r4c2-c3, cyan bar at r5c5-c7 and white key receivers around r4c2 and r6c2-c3. A full-width cyan shutter marked 3 hides the lower chamber.
- Goal
- Clear the upper green/cyan, orange, pink, yellow and white receivers to reduce the cyan shutter to zero. After the shutter opens, feed the key-marked white receivers around the purple lock marked 3, then finish the yellow and purple phases from the upper-left and right-side pipes.
- Opening
- At the start the cyan shutter reads 3. Fill the small green/cyan upper-left receiver first; a few quick clears bring the shutter to 1. Move the orange bar, pink square, yellow bar and white key receiver through the top two rows while the shutter waits for its final clear.
- Danger Zone
- Do not park the long brown bar across r3c2-c5 or a white key receiver in the central throat. Those placements close the only route around the purple 3-lock and strand the lower-left key receivers.
- Mechanics
- A counted cyan shutter gates a second board phase. The revealed lower room contains a purple three-key lock; key-marked white receivers release keys automatically. The top pipe changes through green/cyan, white/blue, yellow and purple, and the last purple load clears the board.
Frequently Asked Questions
What opens the cyan shutter in Level 424?
Clears of the small upper-pocket receivers. The badge starts at 3, drops to 1 after the first few clears, and the shutter disappears after the final one.
How does the purple lock marked 3 work?
Fill the key-marked white receivers in the revealed room. Each clear releases a key that flies to the purple lock automatically.
What is the final move?
When the pipe turns purple, place the purple receiver under the upper-left outlet. Its clear empties the board.
