CubeAway: How to Clear Tilted U-Block Puzzles

To clear tilted U-block puzzles in CubeAway, remove the outward-facing arrows on the exterior tips and outer flanks before touching the interior channel. Tilted formations place two parallel arms across a narrow gap, causing inward-facing blocks to jam against the opposing arm. Dismantling the outer perimeter first opens exit corridors into empty air, allowing you to drain the interior blocks without causing directional deadlocks.

Four-Phase Clearing Sequence

Working from the outside inward prevents cubes from shuddering against blocked paths. Strip the outer layers of both arms to reduce the structure's footprint before attempting to solve the core.

Clearing Phase	Target Block Types	Primary Objective
Phase 1: Prongs	Outward-facing tip blocks	Open escape lanes at the ends of both arms
Phase 2: Flanks	Lateral perimeter blocks	Thin the outer frame structure
Phase 3: Base	External corner and elbow cubes	Separate the two parallel arms
Phase 4: Core	Inward-facing gap cubes	Fire cleanly across newly vacant space

Phase 1 (Prongs): Inspect the extreme ends of the U-shape. Tap every block pointing directly away from the structure into open space to shorten the arms.
Phase 2 (Flanks): Rotate along the outer side walls of both arms. Tap all outward-pointing perimeter cubes, which have unobstructed flight paths away from the center.
Phase 3 (Base): Tap external corner cubes along the connecting elbow to isolate the remaining inner components.
Phase 4 (Core): Clear inward-facing cubes only after their opposing landing zone is completely vacant.

Resolving the Interior Channel Trap

The central hazard of a U-block puzzle is the mutual obstruction between the two parallel arms. A block on Arm A that points directly toward Arm B cannot move until the opposing section on Arm B has been cleared.

To break this gridlock without wasting moves:

Locate Unopposed Vectors: Inspect the inner channel for arrows pointing upward, downward, or lengthwise along the corridor rather than directly across the gap. Longitudinal arrows can slide cleanly out through the open top of the U-shape.
Identify the Anchor Block: Find an individual cube on either arm that points into an already cleared exterior zone. Tapping this block creates a hollow space in the arm's wall.
Execute One-Way Drainage: Tap the opposing blocks on the other arm so they travel across the gap and pass straight through the hollow space into open air. Drain that single side entirely before tapping blocks on the opposite wall.

Camera Alignment for Angled Perspectives

Isometric tilt compresses depth, making it difficult to tell whether an arrow points into empty space or directly into a background block. Never tap based on the default camera angle.

Look down the central corridor: Swivel the camera until you look directly through the hollow channel between the two arms. This sightline shows which blocks protrude into the central airspace and confirms whether longitudinal paths are open.
Look perpendicular to the arm faces: Rotate the puzzle 90 degrees relative to each outer wall. This flat angle confirms whether an outward-facing arrow has an unobstructed exit or terminates into an adjacent corner piece.

Clearing the Curved Base

Once both parallel arms are cleared, the remaining pieces form a compact cluster at the connecting base. At this stage, arrows pointing toward the area formerly occupied by the arms have open clearance to fly free.

Tap the outermost corner blocks pointing away from the base axis.
Fire blocks pointing backward into the open space where the arms were originally located.
Tap the final central base cubes along their linear axis to finish the puzzle.
