Block Out Level 206 Walkthrough: Sorting Strategy and Moves

To clear Level 206 in Block Out, immediately empty one column to create a reusable transfer buffer, then consolidate matching colors onto existing stacks rather than spreading split pieces across open slots. Level 206 traps critical base blocks under multi-layered, mixed-color columns. Clearing this stage requires methodically exposing buried pieces while keeping at least one dedicated transfer lane free to prevent deadlocks.

Opening Priorities: Carving Out a Buffer Tube

Your first objective is securing an entirely empty tube. Dumping mismatched single blocks into empty reserve slots quickly freezes your board.

Scan top-layer colors: Count which color appears most frequently across the tops of all columns. If two or more columns share the same top color, merge them to clear up space immediately.
Target the least fragmented column: Locate the tube containing the fewest alternating color segments.
Transfer to matching hosts: Shift top blocks onto matching host columns whenever possible rather than parking them in empty reserve slots.
Evacuate the final block: Move the last piece out of your targeted column into a matching stack or a temporary slot to secure a clean, empty working lane.

Column State	Board Condition	Immediate Action
High Priority	Column with 2–3 matching top blocks	Merge immediately onto a matching destination column.
Medium Priority	Nearly empty column (1 block remaining)	Evacuate the final block to create an open working buffer.
Low Priority	Mixed column with an isolated top color	Hold moves until a matching host stack has available room.
Restricted	Clean empty buffer slot	Reserve exclusively for unblocking trapped color chains.

Uncovering Buried Base Blocks

Once you secure an open buffer tube, shift your focus to exposing the foundation blocks at the bottom of the board. Leaving base blocks buried forces repetitive, dead-end transfers between upper layers.

Work with follow-up moves planned: When shifting an obstructing top block into your empty buffer, ensure the block revealed underneath can move to a matching column on your next turn.
Avoid parking dead weight: Never move a block into your open buffer if the underlying piece has nowhere to go.
Clear columns systematically: Work through one bottleneck column at a time rather than skimming top layers across the entire board.

Mid-Game Color Consolidation

During the middle phase of the level, multiple columns will hold partial stacks of the same color. Keep these stacks unified to preserve open space.

Merge smaller stacks into larger ones: If a color is divided between a two-block stack in one tube and a single block in another, transfer the single block onto the pair.
Cap full tubes: Consolidate matching blocks until a column reaches its maximum four-block capacity. Completing a full tube permanently removes that color from play and reduces board complexity.
Preserve your transfer buffer: Do not leave an unmatchable piece stranded in your only open column. Storing a dead block in the buffer eliminates your ability to execute multi-step transfers.

Preventing Deadlocks and Closing Out the Puzzle

The endgame begins once three or four colors are fully consolidated, leaving only two or three mixed columns. While more slots become available, careless transfers can still trap remaining pieces.

Do not split matching pairs: Avoid separating an already unified stack of identical blocks unless it is the only legal move required to free a winning base piece.
Avoid lateral shuffling: Shifting the same block back and forth between two tubes wastes moves and complicates tracking without uncovering new layers.
Empty the most fragmented stack first: Transfer the top segment of the most divided column onto its host stack, then route the newly exposed secondary colors directly into their final tubes to finish the stage.
