CubeAway Level 18 Guide: How to Clear Corner-Wrapping Arrows

To solve Level 18 in CubeAway, rotate the cross-shaped cluster continuously to verify where wrapped arrows exit before tapping any block. Unlike straight-line stages, Level 18 introduces corner-wrapping arrows that bend 90 degrees across adjacent faces. Clear the unblocked outer edges of the four cross arms first to open exit lanes, then dismantle the central junction once its corridors are clear.

Understanding Corner-Wrapping Arrow Mechanics

A corner-wrapping arrow does not travel straight off a single face. Instead, the arrow's trajectory bends across a perpendicular 90-degree edge onto an adjoining face.

Because the movement vector turns the corner, checking only the block's starting face will cause mistakes. A block might show an unobstructed departure path from your current viewing angle, but its wrapped path can collide directly into an adjacent cube around the bend. Tapping an obstructed cube locks it in place, requiring you to work around the blockage or restart.

Arrow Path Type	Visual Trajectory	Main Obstruction Risk	Priority Order
Standard Straight Arrow	Direct line off a single flat plane	Blocks ahead on the same face	Tap whenever forward line is open
Corner-Wrapping Arrow	Curves over a perpendicular 90-degree edge	Neighboring cubes along the adjoining face	Inspect the target face before tapping
Core Intersecting Arrow	Starts inside the central junction	Surrounding blocks on all four cross arms	Hold until outer arms are dismantled

Step-by-Step Clearing Sequence for Level 18

Clear the outer tips of the cross cluster first. Attempting to release center blocks early causes jams because the core pieces rely on empty arm corridors to escape.

Inspect the Four Arm Tips: Rotate the cluster to examine the outermost cubes on all four protruding wings. Locate arrows whose corner paths lead outward into empty space rather than back toward the center.
Remove Exposed Perimeter Cubes: Tap the free corner blocks at the wing tips. Removing these outer cubes shortens each arm and reveals the directional markings on the layer beneath them.
Trace Secondary Arm Layers: Rotate to view the newly exposed arm blocks. Trace their wrapped paths around side facets to verify whether earlier removals opened their exit routes.
Isolate the Central Hub: Continue stripping the arms until each wing is reduced to a single connecting block. Rotate 360 degrees to verify that the core exit lanes are fully open.
Dismantle the Core: Tap the remaining central blocks one by one, directing each piece outward through the empty arm channels created during the perimeter clear.

Verification Checklist to Prevent Deadlocks

Before tapping any corner-wrapping block, rotate the camera and run through three checks:

Check the starting plane: Confirm that no adjacent block physically pins the cube at its origin.
Check the corner bend: Track the arrow across the edge seam to determine which adjoining face it enters.
Check the departure corridor: Look along the destination face to ensure the entire slide path is completely clear of other cubes.

If any cube blocks the line on the destination face, leave that block alone and rotate to an alternate arm to find an open path.
