Block Out: How to Clear Levels 146 and 147

To clear Levels 146 and 147 in Block Out, maintain at least one empty or partially filled tube at all times. You fail these stages when every tube fills to capacity with mixed colors, causing a deadlock. Prevent this by systematically peeling back top-layer blocks to reach matching colors underneath and completing four-block single-color sets to reclaim empty slots.

Managing Tube Space in Level 146

Level 146 places mismatched blocks over matching base colors. Opening up usable space is your primary goal.

• Identify the Base Color: Look at the bottom-most block in your most congested tubes to see which color set you need to consolidate.
• Peel Top Layers: Move single top blocks blocking your target color into a tube that already holds that same color, or into an open slot to act as a staging area.
• Complete Four-Block Sets: Focus on filling a single tube entirely with four blocks of one color. Completing a set frees up a tube completely, giving you room to organize remaining blocks.

Avoid scattering single blocks across multiple empty tubes. Keep your most cluttered tubes undisturbed until you create enough space to clean them out.

Sorting Layers and Preventing Deadlocks in Level 147

Level 147 features a wider color distribution that increases the risk of trapping blocks under different colors. Use layer sorting to move top blocks in the exact sequence required to free buried colors.

1. Clear Blockade Colors: Move top blocks that block access to lower layers across multiple tubes.
2. Consolidate Mixed Tubes: If two tubes share the same mixed colors, move matching top blocks into one tube to completely empty the other.
3. Execute Temporary Transfers: Move a target block to an empty staging tube, then stack matching blocks on top to clear congested areas in fewer moves.
4. Plan Initial Moves: Dedicate your first five moves entirely to clearing top blocks from the most congested tubes to open the board.

If you are one move away from a completely full board with no available matches, clear any immediate single-color set to recover an empty slot, even if it interrupts a long-term staging sequence.
