CubeAway Level 393 Guide: How to Clear Arrow Blocks

To clear Level 393 in CubeAway, work from the outer perimeter inward by removing unobstructed cubes first to clear straight exit paths for directional arrow blocks. Arrow blocks move only in the direction their arrow points. If another block occupies that path, moving the arrow block fails.

Clearing Strategy for Level 393

Clearing Level 393 requires systematically dismantling the outer layers of the puzzle structure before attempting to move central arrow blocks.

• Scan the perimeter: Look for edge blocks that either lack arrows or point directly toward empty space outside the grid.
• Remove obstacles: Prioritize clearing non-arrow or static blocks positioned in front of an arrow block's flight path.
• Target anchor blocks: Identify structural blocks holding central clusters in place, and clear them only when an exit path is open.

Step-by-Step Clearing Sequence

Execute your moves in this order to maintain open space and avoid trapped blocks:

1. Locate open arrows: Identify all arrow blocks that currently have an unobstructed path off the board.
2. Clear blocking units: Remove any non-directional blocks obstructing the movement line of arrow blocks.
3. Slide outer arrows first: Remove the available arrow blocks closest to the grid boundaries.
4. Re-evaluate the grid: Check the structure after every move to spot newly exposed paths and available outer cubes.

Preventing Grid Deadlocks

Deadlocks occur when opposing arrow blocks point directly at each other or at static blocks that cannot move. To prevent a deadlock:

• Maintain exit lanes: Keep at least one clear lane to the edge of the board open at all times.
• Avoid early central moves: Do not shift central arrow blocks while outer blocks still obstruct their path.
• Clear smaller blocks: Remove small obstructing blocks early to create room for restrictive directional blocks to navigate toward exit points.
