CubeAway Level 40 Guide: How to Clear the Interlocking Cube

To beat Level 40 in CubeAway, dismantle the puzzle from the outside inward by removing unobstructed perimeter blocks pointing away from the cluster. A block only releases if its straight flight line is completely clear of other cubes. Because Level 40 packs blocks facing opposite directions, tapping inner pieces before stripping the exterior causes collisions that stall your progress.

Four-Phase Clearing Sequence

Work through the cluster systematically to open flight corridors for nested interior arrows.

Phase	Target Blocks	Primary Objective	Key Risk to Avoid
1. Corner Extraction	Outward-pointing corners	Remove free exterior corners to expose adjacent faces	Tapping corners that point into adjacent faces
2. Edge Stripping	Unobstructed perimeter edges	Open outer channels along the boundary lines	Overlooking edge paths blocked by opposing corners
3. Core Decongestion	Newly exposed mid-layer blocks	Clear cross-sections pointing into empty outer zones	Tapping trapped inner pieces before corridors open
4. Final Core Cleanout	Remaining central axis blocks	Remove remaining aligned cubes in direct sequence	Rushing taps and hitting blocked inward-facing arrows

Executing the Sequence

Rotate and clear corners: Perform a full orbital rotation of the cube to locate the corner blocks pointing directly outward into empty space. Tap these first to eliminate the outer anchor points.
Strip perimeter edges: Tap the edge pieces whose directional paths now pass cleanly through the gaps left by the removed corners.
Decongest the core: Rotate the model to inspect newly exposed interior faces. Tap mid-layer blocks whose departure arrows align with the cleared outer channels.
Clear the center axis: Once outer blockers are gone, tap the remaining core cubes in sequence as their straight trajectories become completely unobstructed.

Verifying Trajectories and Avoiding Collisions

Perspective compression in 3D can make an inward-facing arrow appear free when viewed head-on. Rotating the camera properly prevents wasted taps and collision halts:

Use profile angles: Rotate the camera until you view the target block edge-on. If any neighboring block overlaps the path directly in front of the arrow symbol, do not tap it.
Flip the cube when stalled: If no valid moves appear on your current face, rotate the model 180 degrees. Releasing a single block on the opposing side often opens the exit corridor needed for stalled front-facing pieces.
Never force inner blocks: A partially exposed block will not steer around obstacles. If an outer cap block sits anywhere along its axis, remove that perimeter piece before touching the core.
