Sand Blocks: Drop Puzzle Level 166 Walkthrough
Level 166 uses yellow, middle blue/green, and purple feeds around a central 4-counter shutter. Route the 8x7 receiver footprints through the 4/3/2 ice phase, then finish the exposed purple, black, magenta, and green receivers.

How to Solve Sand Blocks Level 166 — Full Solution
- Move the yellow square into r2,c1 and wait for the yellow layer to reach 100%; the central shutter steps from 4 toward 3.
- Route the brown vertical r4-r5,c1, then the green horizontal r1,c2-c3 and short magenta targets r1,c4 and r6,c2; wait after each 100% state.
- Use the white horizontal r7,c5-c7, cyan vertical r2-r3,c8, orange vertical r3-r4,c8, and green vertical r1-r2,c7 as the feed changes to blue/white and orange/cyan.
- Let the three ice footprints count 4→3→2 while the right counter drops through 13, 12, and 11; do not block their center corridor.
- Finish green r7,c4-c5, black r5-r7,c1, purple r6-r7,c3 and r5-r7,c4, the magenta L [(r5,c7),(r6,c7),(r6,c8)], and the remaining purple squares. Stop on the empty-board celebration frame with Level 166 still in the header; no later move is inferred.
Colors in this level:
Yellow, Red, Green, Blue, Cyan, Orange, Brown, Purple, Magenta, White, Black
Common Mistakes to Avoid
- Dragging a long green, white, or purple receiver across r2-r5,c3-c6 before the 4-counter shutter reaches 0.
- Moving the right-side cyan or orange receiver before the ice stack and 19-counter lane have released their next feed layer.
Quick Tips for Sand Blocks Level 166 (quick clues)
- Wait for the yellow receiver to finish its 32%→91%→100% fill before moving the neighboring brown vertical.
- Treat the shutter and right counter as gates; the wider late board is only safe after the ice reads 2 and clears.
Board notes 5 details
- Layout
- Use an 8-column by 7-row grid with r1 below the three source troughs. The opening footprints are green r1,c2-c3; magenta r1,c4 and r1,c5-c6; green r1-r2,c7; purple r2,c1; cyan r2-r3,c8; yellow r3,c7; orange r3-r4,c8; brown r4-r5,c1; green r6,c1-c2 and r6,c4-c5; magenta r6,c2; yellow r6,c7 and r7,c3; and white r7,c5-c7. The central purple shutter occupies r2-r5,c3-c6 and starts at 4.
- Goal
- Fill each receiver to 100%, step the central shutter 4→3→2→0, clear the ice footprints that read 4→3→2, and finish the late purple L [(r5,c7),(r6,c7),(r6,c8)], purple verticals r6-r7,c3 and r5-r7,c4, black r5-r7,c1, and green r7,c4-c5.
- Opening
- Place the yellow square at r2,c1 under the yellow feed and wait through 32% and 91%. Then route the brown vertical r4-r5,c1 and green horizontal r1,c2-c3 while the shutter counter advances. Keep the right 19-counter lane visible.
- Danger Zone
- Do not park a long receiver across the shutter footprint r2-r5,c3-c6. Keep cyan r2-r3,c8, orange r3-r4,c8, the white r7,c5-c7, and the lower purple targets out of the central gate until the ice counters have opened the board.
- Mechanics
- Three changing feed layers, a central 4-counter shutter, a right counter descending from 19, three ice chunks descending 4→3→2, and a late purple/key-style cleanup phase control the route.
Frequently Asked Questions
What blocks the center at the start of Level 166?
A purple shutter fills r2-r5,c3-c6 and shows 4; it must count down before the central receiver corridor is available.
What should I wait for in the middle of the level?
Wait for the three ice footprints to move from 4 to 3 to 2 and for each receiver percentage to settle before selecting the next color layer.
How do I know Level 166 is complete?
The board clears and the video shows the Sand Blocks celebration screen with Level 166 still visible in the header.
