Sand Blocks level guide
Sand Blocks: Drop Puzzle Level 331 Walkthrough
Level 331 is a tall 5x10 board with twin yellow-bordered reservoirs (upper badge 11 at c1-c3 r1-r4, lower coin at c1-c3 r5-r7) and a count-28 cell at c4-c5 r6 that gates the 0:41 phase change. Clear the stacked right-column receivers top-down, drain both reservoirs, then finish the pink striped bar, brown bars and white L-gate revealed after the count reaches zero.

How to Solve Sand Blocks Level 331 — Full Solution
- Let sand flow from the tube at c3 into the right column. The orange block at c4 r1 and pink receiver at c4-c5 r2 fill first; by 2:33 count-28 has stepped to about 26.
- The green receiver at c5 r3 fills and vanishes by 2:23, dropping the count to about 22. Three small receivers have cleared in 20 seconds.
- Feed the red 1x2 bar at c4-c5 r4-r5 next while the upper reservoir badge 11 steps down. Keep c4 clear above the red bar so sand continues past it to the count cell at r6.
- By 1:53 the upper reservoir badge reads about 3. The red bar clears and opens the path to the lower receivers and the count cell.
- Between 1:49 and 1:40 the upper reservoir clears. The count steps 21 at 1:49, 20 at 1:44, 19 at 1:40 as remaining right-column pieces fill. The green inlet pipe at c1 r8 feeds the green triangle at c1-c2 r8-r9.
- Between 1:30 and 1:00 the lower reservoir drains and its coin badge steps toward zero. Green and brown centre receivers fill and clear. The right-column count continues its slow descent.
- Between 1:00 and 0:50 clear the last red bar on the right side. The green triangle, purple blocks and white L-gate remain below r7 awaiting the phase change.
- At about 0:41 the count reaches zero and fires the phase change: a wide pink/purple striped bar appears across c1-c4, brown vertical bars appear at c1-c2, and new pieces fill the cleared upper area.
- Between 0:34 and 0:26 clear the pink/purple striped bar, then the brown bars on the left. Small red and white-outlined pieces at the bottom clear in sequence.
- By 0:22 a blue L-outline at c4-c5 and the white L-gate piece at c1-c2 are the last items. Let them finish filling, then confirm the empty board at about 0:14 when the SAND BLOCKS card plays.

Common Mistakes to Avoid
- Filling the red bar at c4-c5 r4-r5 before the green receiver at c5 r3 has cleared — this blocks gravity flow to the count-28 cell and stalls the countdown, delaying the phase change.
- Using the white L-gate at c3-c5 r8-r10 before the 0:41 phase change — it seals into a dead pocket among the purple blocks and the newly revealed pieces cannot reach the bottom of the board.
- Ignoring the upper reservoir badge 11 while focusing on the right column — both drains share the same tube at c3, so blocking the reservoir path also starves the right-column receivers.
Quick Tips for Sand Blocks Level 331 (quick clues)
- Clear the small orange and pink receivers at c4-c5 r1-r2 first — they are fast 1x1 fills that drop the count quickly.
- Keep c4 clear above the red bar at r4-r5 so sand continues to reach the count-28 cell at r6.
- Save the white L-gate at c3-c5 r8-r10 for the last sequence after the 0:41 phase change.
Board notes 5 details
- Layout
- Five columns c1-c5 by ten rows r1-r10; tube at c3 top with blue-orange sand mass. Upper reservoir c1-c3 r1-r4 (yellow-bordered, striped, badge 11); lower reservoir c1-c3 r5-r7 (yellow-bordered, striped, coin badge). Right column c4-c5: orange block c4 r1, green-outlined cell c5 r1, pink receiver c4-c5 r2, green receiver c5 r3, red 1x2 bar c4-c5 r4-r5, brown count-28 cell c4-c5 r6, small green receivers c5 r7. Bottom: green inlet pipe c1 r8, green triangle c1-c2 r8-r9, purple blocks c2-c4 r8-r10, white L-gate c3-c5 r8-r10, brown and red pieces c4-c5 r9-r10.
- Goal
- The count-28 cell is the master clock — it steps down each time a right-column receiver clears, and reaching zero at about 0:41 fires the phase change. Drain both reservoirs, clear the phase-change pink bar and brown bars, then finish with the white L-gate.
- Opening
- Sand flows into the right column via gravity: the orange block c4 r1 and pink receiver c4-c5 r2 fill first, dropping count-28 to about 26 by 2:33. The green receiver c5 r3 clears by 2:23, bringing the count to about 22. The upper reservoir badge 11 steps down in parallel.
- Danger Zone
- The red bar at c4-c5 r4-r5 blocks gravity flow to the count-28 cell at r6 if it fills before the green receiver at c5 r3 clears — the countdown stalls and the phase change is delayed. The white L-gate at c3-c5 r8-r10 must wait until after the 0:41 phase change, or it seals into a dead pocket among the purple blocks.
- Mechanics
- Twin stacked yellow-bordered reservoirs draining from one tube at c3, a count-28 right-column cell that triggers the 0:41 phase change at zero, a green inlet pipe from the left wall at c1 r8 feeding a triangular receiver, a pink/purple striped bar and brown bars revealed by the phase change, and a white L-gate reserved for the final sequence.
Frequently Asked Questions
What does the count-28 cell control?
It is the master clock for the first half. Each time a right-column receiver fills to 100% and clears, the count steps down by one. When it reaches zero at about 0:41, the phase change fires and reveals the pink striped bar and brown bars for the final sequence.
Why do both reservoirs drain from one tube?
The tube at c3 feeds the upper reservoir at c1-c3 r1-r4 first and the lower reservoir at c1-c3 r5-r7 second. The upper reservoir drains first because it sits directly under the tube; the lower receives overflow once the upper is partly drained.
When should I use the white L-gate?
After the 0:41 phase change. It sits at c3-c5 r8-r10 among the purple blocks, and activating it before the phase-change pieces are introduced traps it in a dead pocket with no sand to fill.
