How to Clear Block Out Block League Rounds 4, 5, and 6

To clear Rounds 4, 5, and 6 in the Block Out Block League, keep at least one container completely empty to serve as a move buffer, then clear single-color stacks and high-frequency colors to keep board space open.

Core Container Management Strategy

Managing empty space dictates success across all three rounds. A completely open container provides room to shift blocking colors away from buried pieces.

Maintain a Buffer Container: Always keep one empty tube available. Moving blocks into a buffer zone allows access to required colors underneath.
Clear Single-Color Stacks First: Check the board immediately at the start of a stage. Complete any single-color stacks right away to free up permanent container space.
Avoid Half-Filled Tubes: Do not split multiple colors across partially filled containers. Distributing different colors across open tubes creates bottlenecks that prevent full clears.
Verify Destination Capacity: Confirm that the target container has sufficient remaining capacity before initiating a color transfer.

Round 4: Dominant Color Sequencing

Round 4 introduces tighter spatial layouts. Success requires clearing dominant colors that appear most frequently on the board first.

Targeting high-frequency colors opens up container slots quickly. When grouped blocks of the same color are available, transfer them together rather than shifting individual pieces. Finish one full color container completely before transferring a new color to avoid cluttering open slots.

Round 5: Look-Ahead Color Sorting

Round 5 increases the mix of colors within each container. Clear these dense arrangements by planning moves two steps ahead to avoid trapping essential lower blocks.

Identify the color sitting at the bottom of a mixed container.
Target matching blocks across the board to fill that bottom color's container faster.
Stack identical colors temporarily in an empty container when digging for a needed color underneath.
Avoid dropping a new color onto a partially filled container unless a clear extraction path is available for the top block.

Round 6: The Cycle Method for Dense Boards

Round 6 features high block density across all available containers. Handle these cluttered layouts using a cyclic relocation method: create one open container, use that space to clear a specific color path, and consolidate remaining stacks.

If a sequence creates a dead end, backtrack or undo the move sequence. Identify whichever color causes the primary blockage across open containers. Consolidating even one full tube of that main blocking color opens enough space to solve the rest of the board.

Strategy Trade-offs and Move Efficiency

Block League stages do not penalize total move counts, but fail state conditions trigger whenever no valid color moves remain.

Strategy Goal	Recommended Action	Trade-off
Prevent Board Lock	Take longer move sequences to preserve an empty container.	Requires more total transfers, but avoids irreversible block traps.
Manage Full Workspace	Clear single-color stacks early, even if partial stacks remain.	Frees up immediate buffer space at the cost of delayed secondary clears.
Resolve Dense Round 6 Boards	Target and eliminate the single most dominant blocking color.	Uses multiple temporary slots up front to achieve mid-stage space.

When container space narrows during Round 6, prioritize consolidating single-color stacks first. Clearing a single stack resets board layout space and provides room to finish the level.
