Block Out Level 366 Guide: Step-by-Step Sorting Strategy

To clear Level 366 in Block Out, immediately create an empty buffer tube by transferring matching surface blocks into existing partial stacks. Once an empty tube is secured, use it strictly as a temporary holding lane to consolidate split colors and expose buried pieces without jamming your remaining spaces.

Free an Early Buffer Tube

Your first bottleneck in Level 366 is the lack of open maneuvering space. Because identical colors are scattered across several densely packed columns, you cannot organize lower layers until at least one column is completely vacant.

Scan the top layer: Identify which column requires the fewest transfers to empty completely. Look for columns where the surface blocks can immediately move onto matching stacks elsewhere.
Execute direct matches: Transfer surface blocks only onto existing stacks that share the same color and have open capacity.
Empty the chosen column: Move the remaining pieces out until one tube is completely clear.
Reserve the open tube: Do not park unrelated single blocks in this newly opened space unless doing so directly uncovers a block needed to continue a matching chain.

Consolidate Split Colors

After securing your buffer tube, focus on colors that are spread across three or more columns. Leaving a color divided across multiple tubes restricts column height across the entire board.

Target surface-heavy colors first: Choose the color with the most pieces already exposed on top layers and group them into a single column.
Respect stacking rules: You can only place a block onto an identical color or into a fully empty tube. Never commit a block to an empty tube without a plan to either build that color completely or clear the slot again quickly.
Clear secondary positions: Continue transferring matching pieces until secondary tubes are freed from that color, increasing your available vertical space.

Mid-Stage Column Management

As stacks partially consolidate, the board becomes vulnerable to deadlocks when single contrasting tiles block access to deep foundational pieces. Use the buffer slot to resolve these bottlenecks systematically.

Board State	Recommended Action	Tactical Goal
Surface block has an open matching stack	Transfer directly to the matching stack	Deepens space in the source column
Surface block traps a piece needed elsewhere	Shift the surface block into the buffer	Unlocks the buried piece for a chain transfer
Empty tube available with multiple move options	Transfer a uniform color cluster	Builds a full stack while preserving maneuvering room
Column contains only two alternating colors	Shift alternating pieces via the buffer	Separates the two colors into clean, dedicated tubes

Execute the Final Clear

When only two or three colors remain mixed, completed tubes will already be locked in, leaving very few active columns.

Plan in reverse: Before committing your final moves, check where each remaining color will settle so you do not isolate a single block without an open tube.
Keep one alternating lane open: Maintain at least one column with available capacity until all pieces of the penultimate color are assembled.
Complete the final stacks: Fill the penultimate tube to full capacity, which leaves the last open column ready to receive the remaining uniform blocks for the clear.
