Block Out Level 84 Strategy: How to Sort Blocks and Clear Tubes

To beat level 84 in Block Out, keep at least one tube entirely empty throughout the stage to act as a dedicated staging area. Immediately shift single-color blocks sitting at the top of mixed stacks into this empty space. Reducing stack heights exposes hidden lower layers and prevents deadlocks that stop board progress.

Managing Tube Capacity and Anchor Colors

Never fill every tube to maximum capacity with mixed colors. Keeping one empty tube provides the necessary space to cycle blocks out of the way without clogging the board. Focus on the bottom-most color in each column, treating these base pieces as anchor colors:

• Expose Base Anchors: Shift the top layers of mixed stacks into your empty staging tube to reach the bottom colors.
• Target Near-Empty Columns: Clear columns that are closest to full resolution first to create extra empty workspace quickly.
• Consolidate Matching Colors: Move blocks into their designated color-coded tubes only when those tubes no longer need to serve as temporary pass-throughs for other colors.

Step-by-Step Move Sequencing

Evaluate your move sequence before shifting pieces to ensure you do not trap colors needed for upcoming steps.

1. Clear Top Layers of Dominant Colors: Identify the most frequent top-layer color on the board and clear those blocks first to lower vertical stack height.
2. Shift Secondary Colors to Staging: Move blocking pieces into your open tube to uncover direct access to base anchor colors.
3. Unblock Base Target Colors: Check the bottom of each column to identify trapped colors, making them your primary targets for extraction.
4. Finalize Sorted Tubes: Transfer matching color groups into their dedicated tubes once no other pieces need to pass through them.

Avoid making quick, random moves to keep the board moving. Level 84 requires careful space allocation and move discipline over speed.
