CubeAway Level 18 Guide: How to Clear the Puzzle in Fewer Moves

To clear Level 18 in CubeAway in fewer moves, rotate the puzzle to find and tap completely unobstructed outward-facing blocks on the perimeter before attempting to touch any interior cubes. Tapping a cube that collides with an adjacent block causes it to wiggle in place, wasting a move without clearing any space.

Executing a full orbital rotation before making your first move ensures every tap ejects a cube from the board.

Outside-In Block Priority

Level 18 packs cubes tightly across the X, Y, and Z axes. Success requires an outside-in peeling strategy so that each removed piece opens an exit corridor for the pieces trapped behind it.

Block Position	Arrow Trajectory	Clearing Priority	Move Efficiency Impact
Perimeter Outward	Points directly into open space away from the cluster	1 (Immediate)	1:1 tap-to-clear ratio with zero obstructions
Semi-Exposed Tangential	Points parallel along an outer face	2 (Secondary)	Clears once adjacent perimeter blocks leave
Core Inward-Facing	Points directly into neighboring blocks	3 (Final)	Wastes moves if tapped before its flight path clears

Step-by-Step Clearing Sequence

Follow this three-phase progression to avoid invalid taps on Level 18:

Remove the exterior corners: Rotate the camera around the cluster to find corner blocks with arrows pointing away from the core. Because corner blocks have multiple exposed faces, they offer the cleanest starting exit trajectories.
Strip the perimeter edges: With corner obstacles removed, inspect the remaining outer edge blocks. Lateral arrows that were previously blocked can now fly into the empty space. Rotate the view 90 degrees after each tap to confirm newly opened pathways.
Dismantle the central core: Once outer barriers are peeled away, the inner cubes gain clear departure paths along multiple axes. Align your view with each arrow's forward axis before tapping to ensure the flight line is clear to the border.

Avoiding Wasted Moves

Move penalties on Level 18 typically happen for two reasons:

Perspective distortion: A cube can appear unobstructed from a diagonal view even when a corner block slightly overlaps its departure path. Rotate the camera so the arrow points straight toward or away from your perspective to verify clearance before tapping.
Directional locks: When Block A blocks Block B's path while Block B's arrow points elsewhere, identify which block serves as the anchor. Removing the anchor piece frees the dependent piece, whereas tapping the dependent piece first results in a failed move.
