Block Out Level 158 Solution: Move Order and Tube Strategy

To clear Level 158 in Block Out, focus on completely emptying one tube within your first few moves instead of scattering blocks across available slots. An empty tube acts as your required transit buffer. Once you open that lane, use it strictly to dig out buried matching segments, transfer exposed colors into uniform sets, and keep at least one column open to prevent board deadlocks.

Opening Moves: Clearing Your First Buffer

The starting layout of Level 158 splits matching colors under mixed surface blocks. Attempting to complete a full color stack right away usually jams your board, because completed tubes lock down space while mixed tubes remain trapped. Mobility is the initial priority.

Find the shallowest split column: Survey the board for a tube that contains only two colors—ideally a single rogue block resting on top of a matching base.
Transfer the top block: Move that rogue top segment onto an identical exposed color in another tube, or place it into an empty auxiliary lane if no match is available.
Evacuate the column: Move the remaining uniform base blocks into an empty slot or merge them with their matching group elsewhere.

Once that column is clear, leave it empty. Do not park random single blocks in this space unless you can clear them out on the very next turn.

Mid-Game Sequencing: Color Consolidation

With an open buffer available, work through the board one color set at a time. The objective in the mid-game is reducing the total number of colors circulating across your mixed tubes.

Phase	Primary Objective	Tactical Action	Risk to Avoid
Opening	Establish mobility	Empty a single column to create a transit lane	Scattering lone blocks across empty slots
Mid-Game	Excavate layers	Route blocks through the buffer to expose buried sets	Parking a non-matching block in your transit lane
Late Game	Final assembly	Consolidate remaining pairs into completed tubes	Leaving two mixed columns with no open moves

Follow this transfer order during mid-game sorting:

Target the dominant visible color: Count which color has three exposed or easily reachable pieces. Concentrate your transfers on grouping that color into a single designated column.
Stage blocks temporarily: Move a blocking piece into your empty buffer only when that move immediately reveals a color that matches another column.
Clear the buffer immediately: Once the revealed color is moved, transfer the staged piece out of the buffer and onto its matching partner.

Endgame Execution and Deadlock Prevention

The endgame of Level 158 leaves you with two or three partially filled columns holding interlocking pairs. Because board space is restricted, any misallocated piece can lock the stage.

To resolve the remaining columns without jamming:

Execute triangular transfers: Move the top block of column A into the buffer tube. Shift the newly revealed lower block of column A onto its match in column B. Finally, move the staged block from the buffer into its matching slot in column B or a designated home tube.
Keep exit paths verified: Before picking up any block, confirm where the block beneath it will go on the subsequent move. If moving a block does not expose a playable match, leave it in place.
Never cap an unfinished tube: Placing an unrelated color on top of an incomplete stack locks that column and wastes depth. Keep matching colors grouped together until the column is full.
