Sand Blocks level guide
Sand Blocks: Drop Puzzle Level 350 Walkthrough
Level 350 is a super-hard six-column board with a compact top grid carrying counters 6, 2 and 1, two stacked purple reservoirs marked 3 and 13, a gold-key/cyan-padlock gate and a late right-side green feed. Clear the triple counters, drain both reservoirs in order, then unlock the padlock to finish.

How to Solve Sand Blocks Level 350 — Full Solution
- Let the red sand mass at c1-c2 r1 fill the blue quarter-arc at c1-c2 r2-r3 via the left tube; it clears at about t=8s and counter 6 steps from 6 to 5.
- Keep c3-c4 open so the green vertical receiver catches tube outflow; it fills by about t=12s as counter 6 continues stepping.
- Clear the magenta receiver at c5-c6 r1 and the orange receiver at c5-c6 r2 in turn; counter 6 drops through 4 and 3 by about t=16s.
- At about t=22s counters 6, 2 and 1 all reach zero and the yellow bar at c4-c6 r3-r4, white bar at c3-c4 r3 and magenta key cell clear, opening the path to the upper reservoir.
- The upper reservoir (badge 3) drains from about t=28s: badge shows 2 at about t=30s, 1 at about t=40s and clears at about t=56s, turning the c1-c6 r5-r7 area into dark terrain.
- At about t=58s the cleared reservoir reveals mid-board pieces — orange-brown bars at c2-c5 r5-r7 and a magenta vertical receiver at c1-c2 r6-r8. Clear them top-down while the lower reservoir (badge 13) begins stepping.
- The lower 13-count reservoir steps roughly every six to eight seconds. At about t=98s the badge reads 2 and a gold key appears at c2 r7-r8; a cyan padlock sits at c5 r6. Keep the lane between them clear.
- Clear remaining orange and magenta mid-board pieces while the gold key travels toward the padlock; the pink inlet at c6 begins delivering green sand from about t=108s.
- At about t=128s the gold key reaches the padlock, the lock clears, and the final pieces below the lock line — dark bars at c1-c3 r9-r10 — become clearable.
- The right-side green feed finishes the last receivers; the board empties at about t=152s (timer 00:12) and the SAND BLOCKS card plays.

Red, Blue, Green, Magenta, Orange, Yellow, White, Cyan, Purple
Common Mistakes to Avoid
- Dragging the orange-brown L at c4-c5 r2-r3 across the green receiver's column in the first ten seconds, which blocks tube outflow and stalls counter 6.
- Starting on the lower 13-count reservoir before the upper reservoir's badge 3 has fully cleared, leaving upper pieces in the drain path.
- Filling the c5 column with a piece before the gold key arrives at the cyan padlock, which strands the lock and prevents the final clearing phase.
Quick Tips for Sand Blocks Level 350 (quick clues)
- Clear counters 6, 2 and 1 before expecting the upper reservoir to drain — all three share the top-grid path.
- Drain the upper reservoir (badge 3) completely before starting on the 13-count reservoir below it.
- Keep the c5 column clear for the cyan padlock until the gold key arrives from the left side.
Board notes 5 details
- Layout
- Six columns (c1-c6) by ten rows (r1-r10); a left-wall tube enters at c1 r1-r2. Top grid (r1-r4): red sand mass at c1-c2 r1, blue quarter-arc at c1-c2 r2-r3, green vertical 1x2 receiver at c3-c4 r1-r2, magenta receiver at c5-c6 r1, orange receiver at c5-c6 r2, orange-brown L at c4-c5 r2-r3, white bar at c3-c4 r3, yellow bar at c4-c6 r3-r4 carrying counter 2 and counter 1, magenta key cell at c5-c6 r3, counter 6 badge on left wall at r2. Below: upper purple reservoir at c1-c6 r5-r7 badge 3, lower purple reservoir at c1-c6 r8-r10 badge 13, pink side inlet at c6 r5-r6.
- Goal
- Step counters 6/2/1 to zero to open the upper reservoir, drain badge 3, then drain badge 13 and unlock the gold-key/cyan-padlock to clear the final pieces via the late right-side green feed.
- Opening
- Let red sand at c1-c2 r1 drain into the blue arc at c1-c2 r2-r3 from the left tube. Keep c3-c4 clear for the green vertical receiver. Counter 6 steps from 6 quickly as top-grid receivers clear; counters 2 and 1 follow on the yellow and white bars.
- Danger Zone
- Dragging the orange-brown L at c4-c5 r2-r3 across c3-c4 in the first ten seconds blocks tube outflow and stalls counter 6. In the late game, filling c5 r6 before the gold key reaches the cyan padlock strands the lock and the 13-count reservoir stalls.
- Mechanics
- Super-hard density, triple counters 6/2/1 gating the upper reservoir, stacked reservoirs 3 then 13 as sequential master clocks, a gold key at c2 r7-r8 / cyan padlock at c5 r6 pair gating the final phase, and a late right-side green feed from the pink inlet at c6.
Frequently Asked Questions
Why won't the upper reservoir drain even though the top grid looks empty?
Counters 2 and 1 on the yellow and white bars must also reach zero; they share the vertical path the reservoir needs to open.
What triggers the gold key to appear?
The gold key appears on the left side at about c2 r7-r8 once the lower reservoir badge is nearly spent — at about badge 2. It travels rightward toward the cyan padlock at c5 r6.
How does the green sand from the right side help?
Once the padlock clears, the pink inlet at c6 delivers green sand that fills and clears the last receivers in the bottom rows, finishing the board without needing the left tube.
