Block Out Level 426 Guide: How to Clear and Route Blocks

To beat Level 426 in Block Out, immediately clear blocks that have a direct, unobstructed line to their matching colored perimeter doors. Sliding straight-line pieces out first creates board space and prevents early deadlocks. Once open lanes exist, move obstructing pieces into dead-end staging pockets rather than parking them across central intersections.

Planning the Opening Move Order

Level 426 boxes multi-colored sliding blocks into a shared grid bordered by color-coded exit gates. Because blocks travel continuously along straight horizontal or vertical lines until they hit an obstacle, a wall, or their matching door, parking an off-color piece in a crossway will trap every block behind it.

Scan the grid before your first move using this priority order:

Locate zero-move exits: Identify any block or paired cluster that directly faces its matching perimeter door. Slide these out immediately to establish open transit channels.
Identify single-block blockers: If no block has an open path, slide the single piece whose relocation opens an immediate exit for a matching block.
Keep transit lines clear: Avoid sliding interior blocks into perimeter lanes unless those perimeter spots have no connecting traffic.

Phase	Primary Objective	Key Risk to Avoid
Early Phase	Discharge unblocked edge pieces	Parking off-color blocks in active exit lanes
Mid Phase	Move blocking units into open pockets	Sealing intersection junctions between colors
Late Phase	Route deep interior blocks directly to gates	Sending blocks to far walls without a turning point

Managing Transit Lanes and Staging Pockets

As the board begins to clear, you must distinguish between active transit corridors and staging pockets.

A transit corridor is any lane connecting an interior block to its target door. A staging pocket is an isolated perimeter tile or dead-end recess that does not cross another piece's exit route.

When you must shift an obstacle to unblock another piece:

Slide the obstacle firmly into a staging pocket outside the main traffic flow.
Clear the freed block through its matching gate immediately.
Return the staged block to an active lane only when its own exit route is accessible.
Never leave an off-color piece sitting across an intersection, as crossway blockages account for most resets on this stage.

Preserving Pivot Blocks for Compound Turns

Midway through Level 426, several blocks will require compound turns—sliding horizontally across an open lane before turning vertically into a door. Because sliding blocks do not stop on empty tiles, they require a collision backstop to halt their movement in line with an exit door.

Do not clear neighboring pieces prematurely if an unaligned block relies on them as a stopping point. If sliding a piece across an empty row sends it all the way to an outer wall where it loses alignment with its door, keep an adjacent block in place to serve as a temporary pivot. Once the primary block collides with the backstop and turns into its gate, eject the pivot block.

Executing the Final Cleanup

When only three or four blocks remain, the empty board increases the risk of overshooting exit channels:

Calculate the final resting point of each slide before moving, ensuring the block stops perpendicular to its matching door.
Confirm that sliding one piece does not push an adjacent piece out of alignment with its exit gate.
Slide the remaining blocks one by one into their matching perimeter doors to complete the level.
