CubeAway Levels 16 to 20 Puzzle Solution and Clearing Guide

To clear levels 16 through 20 in CubeAway, clear exposed outer-edge blocks whose arrows point toward open space, then rotate the 3D puzzle structure to uncover and unblock inner layers. Avoid tapping blocks randomly, as layered block arrangements will lock the board if dense clusters are cleared out of sequence.

Level 16: Directional Priority and 360-Degree Rotation

Level 16 introduces larger block clusters that require clear directional ordering.

1. Scan Outer Edges: Look along the exterior of the 3D structure for blocks pointing away from the cluster into empty space.
2. Remove Unlocked Blocks: Tap outer-facing blocks first to open space around the perimeter.
3. Rotate 360 Degrees: If progress stops, rotate the structure entirely to locate key blocks on the opposite side. Removing a single exposed block on a far face often frees three to four adjacent blocks previously trapped by collision logic.

Levels 17 and 18: Bottleneck Blocks and Cluster Thinning

Levels 17 and 18 introduce denser block formations where specific bottleneck blocks hold entire sections in place.

• Work Outside-In: Target the edges of dense clusters first. Thinning the outer perimeter prevents center blocks from becoming completely trapped.
• Group by Orientation: Remove pairs or small sets of blocks that share the same directional orientation. This strategy minimizes unnecessary rotations and reduces mis-taps.
• Prioritize Center-Away Arrows: Focus taps on blocks pointing directly away from the core of the mass to preserve maneuverability around inner layers.

Level 19: Clearance Zones and Congestion Management

Level 19 features tighter block spacing, raising the risk of deadlocks if open space is not preserved.

• Maintain a Clearance Zone: Keep at least one full face of the 3D cube clear. An open face gives you a clear line of sight when rotating to inspect inner layers.
• Find Hidden Single Cubes: When all visible paths seem blocked, rotate the object to check for tiny, individual cubes nestled between larger sections. Removing one exposed minor block typically releases a chain reaction of dependent cubes.

Level 20: Pre-Move Scans and Final Sequences

Level 20 combines complex rotations with tight directional restrictions.

1. Perform a Pre-Tap Rotation Scan: Before your first move, rotate around all four main sides to determine which face contains the highest number of immediately removable blocks.
2. Clear One Face at a Time: Fully strip exposed blocks from one side before shifting focus to the next face to maintain an organized grid.
3. Check End-Game Obstructions: As the remaining structure shrinks, spatial restrictions tighten. If a remaining block fails to clear, rotate the structure slightly to verify whether an adjacent block is still blocking its exit path.
