CubeAway: How to Solve Hard Level 89

To beat Hard Level 89 in CubeAway, dismantle the puzzle from the outside inward. You must clear fully unobstructed exterior blocks first, rotate the camera to inspect arrow trajectories from multiple angles, and systematically untangle the interlocking mid-layer before touching the dense inner core.

1. Strip the Outer Perimeter Blocks

Do not tap blocks in the central column or inner tiers during the opening moves. Level 89 packs cubes closely together, causing inward-facing arrows to collide with neighbors if tapped out of sequence.

Start by rotating the puzzle to identify cubes whose arrows point directly outward into empty space:

• Corner Blocks: Tap any exterior corner cube with an arrow facing away from the structure into the void.
• Flank Cubes: Remove perimeter cubes along the horizontal axes that have entirely clear exit trajectories.
• Top Caps: Tap unobstructed upper-tier blocks pointing straight up.

Removing these peripheral blocks clears exit corridors and eliminates visual clutter, exposing the blocked faces of the intermediate layer.

2. Rotate the Camera to Trace Exit Lines

Static viewing conceals collisions. An arrow may look clear from a flat perspective while its path is clipped by a neighboring cube's corner. Rotate the model in small increments to confirm true clearance before tapping.

Trace the entire flight path of an arrow past the edge of the board. If any cube boundary overlaps that path, leave the block in place and target the obstruction first.

3. Untangle Interlocking Mid-Layer Pairs

Once the perimeter shell is gone, Level 89 reveals an intermediate layer dominated by reciprocal blocking, where two or more blocks obstruct each other. Random tapping risks collisions and misclicks.

Resolve these deadlocks by finding an anchor piece—a cube blocked by only one other block:

1. Locate a cube that has only one obstruction directly in front of its arrow tip.
2. Rotate the camera to inspect the obstructing cube and find where its own arrow points.
3. Remove the secondary support piece that prevents the obstructing cube from escaping.
4. Tap the obstructing block to eject it into the vacant lane.
5. Tap the freed anchor block to release the rest of the cluster.

4. Dismantle the Central Core

After clearing the outer and middle layers, a compact core of inward-facing or spiraled blocks remains.

To clear the final cluster:

1. Identify the core keystone block whose arrow points straight outward through one of the hollow channels opened in earlier steps.
2. Tap the keystone block to trigger a clean exit.
3. Follow the sequence as neighboring core blocks lose their barriers, clearing each remaining piece one by one until the stage is complete.
