Magic Sort! Level 634 Guide: Tube Routing and Deadlock Prevention

To clear Level 634 in Magic Sort!, preserve at least one of your two starting empty tubes as a temporary transit slot while consolidating matching surface colors into the other. Filling both empty tubes with unmatchable single units eliminates your maneuvering space and triggers a mid-stage deadlock.

Tube Mechanics and Opening Setup

Level 634 starts with several four-unit tubes filled with interleaved colored liquids and two empty utility tubes. A tube is solved and sealed once it holds four units of a single color.

Before making an initial pour, scan the top layer across all filled tubes to identify:

• Identical colors exposed on the surface of two or more tubes.
• Sub-surface colors that can match an exposed top layer once uncovered.
• Mixed tubes with shallow color distributions that can be emptied quickly.

Buffer Tube Management

Your two empty containers are the primary tool for unraveling interleaved layers. Use them with distinct roles rather than treating both as general storage:

Never leave mismatched colors inside Buffer Tube B. Once a transit piece is moved into it, the newly revealed color below must immediately transfer to another vial, allowing you to empty Buffer Tube B right away.

Color Routing Sequence

Follow this order of operations to clear tubes systematically without clogging the board:

1. Merge Exposed Surface Pairs: Pour matching colors directly into each other when headroom exists. If no direct pour is available, combine matching surface units into Buffer Tube A to build a solid two-unit or three-unit base.
2. Empty the Shallowest Mixed Tube: Focus on removing all layers from one specific mixed tube. Completely draining a container creates a fresh, empty buffer space, expanding your routing options.
3. Uncover Buried Base Colors: Once a donor tube is cleared, dig through stacks where the bottom-most segment matches an established stack in another tube. Moving the upper units out lets you transfer the bottom piece to complete a four-unit seal.

Avoiding Mid-Puzzle Deadlocks

A deadlock occurs when all tubes contain liquid, no surface colors match, and neither buffer tube is empty. Prevent this failure state by tracking space constraints:

• Check Destination Capacity: A four-unit tube can only accept liquid equal to its remaining empty slots. Attempting to transfer two units into a tube with only one open slot leaves the second unit stranded on the source tube.
• Do Not Split Built Stacks: Never place an unrelated color on top of a tube that already holds two or three consolidated units of another color.
• Verify the Next Move Before Parking: Before placing a blocking unit into an empty tube, confirm that the layer beneath it has an open, legal destination. If it cannot move, do not make the initial transfer.

Once you assemble and seal your first two complete tubes, board congestion decreases. Use the newly emptied slots to cycle remaining liquid pairs into full four-unit sets to finish the level.
