Block Out Level 622 Guide: How to Clear Bottlenecks and Tray Stacks

To beat Level 622 in Block Out, dismantle the tall central column bottleneck first, route direct surface matches immediately, and preserve at least three empty slots in your holding dock. Only move a blocking piece into the tray if it immediately exposes a tile needed by an active gate. Never park unneeded orphan colors in the dock without an exit path, as running out of buffer space will trigger an unrecoverable deadlock.

Board Layout and the Central Bottleneck

Level 622 arranges colored tiles in deep, multi-tiered vertical stacks. The primary obstacle is the central column, which locks away essential colors required by active target gates beneath mismatched foreground tiles.

Tapping outer tiles indiscriminately leaves the central stack trapped while scattering unaligned colors across your board. Before tapping your first piece, trace the vertical color order of each lane. Identify which lanes feed active target gates immediately and calculate the exact moves required to expose the matching tiles locked inside the central stack.

Move Priority and Tray Buffer Management

Maintaining at least three open slots in your holding dock is necessary to survive mid-stage transitions. The holding dock is temporary staging space, not storage. If you fill dock slots with mismatched orphan colors, you lose the maneuvering room required to dig into deep stacks.

Evaluate every potential move by its net impact on your buffer capacity:

Move Type	Player Action	Board Impact	Risk Level
Direct Gate Route	Tap block matching an open gate	Clears immediately without using dock space	Low
Unmasking Shift	Move blocker into holding dock	Exposes hidden block needed for an active gate	Medium
Speculative Shift	Move unneeded block into holding dock	Fills buffer slot without a guaranteed match	High (Avoid)
Multi-Match Burst	Route sequential matching colors	Clears buffer slots rapidly and unlocks lane depth	Optimal

Only shift a blocker into the dock if the piece directly behind it clears into a gate or matches a tile already in your tray. If a move merely reveals another obstacle, leave it alone until an exit route opens.

Three-Phase Step-by-Step Clearing Sequence

Work from the center outward to create the lateral room needed to clear outer lanes:

Phase 1: Direct Clearance and Perimeter Opening. Tap visible surface blocks that match active gates. Route these pieces directly to collection points without touching the holding dock.
Phase 2: Center-Column Unlocking. Target the tall middle stack. Move the top blocker into the holding dock only when it reveals a color required by an active gate, then route that revealed piece immediately to reclaim your empty slot.
Phase 3: Side-Lane Consolidation and Final Cleanout. Once the center column is dismantled, clear the remaining side lanes. Pair matching colors into open gates and clear residual blocks in descending order of stack height.

Preventing Tray Deadlocks

Prematurely filling the dock with mismatched orphan blocks causes most failures on Level 622. Spreading single red, blue, green, and yellow tiles across separate tray slots freezes the board because gates require full sets to clear.

Always monitor your open slot count before tapping. If your tray drops to only two open slots without a guaranteed match, stop unstacking new lanes. Scan the board for an exposed tile that matches a block already sitting in the dock, and route it immediately to restore buffer capacity before taking any other action.
