To clear Level 487 in Block Out, slide outer boundary pieces into flank pockets before shifting the central cluster. Prematurely moving pieces in the center creates irreversible traffic jams around high-traffic junctions. Shifting peripheral tiles first clears lateral sliding lanes, allowing you to slide long anchor blocks backward and open paths to the exit doors.
Level 487 Clearance Sequence
Level 487 requires a four-phase clearing sequence. Shifting pieces out of order risks trapping trailing blocks behind closed gates.
| Move Phase | Target Block Focus | Primary Objective |
|---|---|---|
| Phase 1: Perimeter Release | Outer flank tiles and single-unit obstacles | Open lateral slide lanes and create boundary pockets. |
| Phase 2: Keystone Unlocking | Long anchor blocks in central corridors | Slide anchor pieces backward into open perimeter space. |
| Phase 3: Color Exit Routing | Unblocked primary color groups | Direct completed color sets into matching exit doors. |
| Phase 4: Final Clearance | Trailing pieces and buffer occupants | Empty temporary holding spots directly into exit gates. |
Clearing Perimeter Lanes and Central Anchors
The opening five to ten moves determine whether the board remains manageable. Avoid pushing central tiles right away. Long blocks act as structural pins across the main arterial corridors, preventing cross-lane movement until neighboring single units vacate the area.
- Shift flank tiles outward: Move perimeter single units into open boundary pockets to relieve congestion across the main corridors.
- Expose secondary colors: Nudge partially blocked pieces toward the perimeter edges so their exit lanes become accessible.
- Retract the anchor blocks: Once outer space is open, slide the central anchor blocks backward. Ensure an anchor does not slide into a dead-end pocket that traps a smaller piece behind it.
Buffer Slot Management Rules
Temporary holding slots are strictly for short-term transit. Filling them without an immediate exit plan causes mid-game deadlocks.
- Require an immediate exit: Only place a block into a buffer slot if that move directly enables another block to exit the board on the next turn.
- Maintain one open slot: Keep at least one buffer slot completely empty so multi-tile shifting chains do not stall.
- Empty slots within two moves: When an exit door clears board space, immediately retrieve stored blocks from the buffer rather than moving new pieces in.
Exit Routing Priority
After the central anchor blocks are dislodged, route blocks systematically from the deepest interior sections out toward the perimeter gates.
Target the most restricted color group first. Because its exit paths run through the narrowest corridors, clearing this color group early removes the tightest bottlenecks on the board. Once the restricted color is eliminated, guide the remaining colors through their open straight-line paths to complete the level.

I wish I had read this before upgrading the wrong thing.
This saved me time in the early game.
Good guide for Block Out players. The strategy part was useful.
This guide answered the exact question I had.
