Magic Sort! Level 837 Walkthrough Guide

To clear Level 837 in Magic Sort!, merge exposed top colors across your starting tubes before committing any liquid to your two empty buffer bottles. Every bottle holds a maximum of four units, and you can only pour liquid into a tube if the receiving top color matches or if the tube is entirely empty. Success on this stage requires preserving both empty slots to cycle trapped mid-layer colors into full, locked bottles.

Level 837 Setup and Tube States

Level 837 starts with multiple mixed tubes and two completely empty buffer tubes. The primary hurdle is color fragmentation: single-unit and double-unit segments sit buried beneath conflicting tops. If you fill both empty tubes with mismatched colors early, you eliminate your board mobility and trigger an unavoidable deadlock.

Tube State	Board Role	Primary Risk	Action Rule
Empty Buffer Tube	Receives any color to enable chain moves	Clogged easily by isolated single units	Keep empty until executing an active multi-pour sequence
Mixed Tube (3–4 colors)	Holds buried mid-layer and base colors	Blocks transfers across multiple layers	Strip top colors first to expose matching lower tiers
Consolidated Tube	Accumulates matching units toward a clear	Temporarily ties up tube volume	Pour matching units until all four slots are filled

Opening Strategy: Consolidate Exposed Layers

Begin by scanning the visible top layer of every column for duplicate colors:

Merge top-tier duplicates: Pour exposed matching colors directly onto one another without using the empty tubes. This condenses scattered units and creates empty capacity in the donor bottles.
Prioritize congested stacks: Target tubes containing three or four distinct color bands. Stripping the top segment from these bottles reduces board complexity and reveals buried layers.
Protect buffer slots: Never pour a single color unit into an empty tube unless that move directly uncovers a matching color beneath it that can be moved immediately.

Mid-Game Routing and Deadlock Prevention

Once initial moves reveal deeper layers, managing buffer capacity becomes your central priority. Two common errors cause failed runs on this stage:

The trapped single unit: Moving a single unit into an open tube to uncover a lower tier leaves that tube restricted. If the remaining units of that color are buried under other stacks, that buffer slot remains blocked.
Premature partial fills: Stacking three units of a color into an empty tube while the fourth unit remains buried at the bottom of an untouched column leaves the buffer with only one usable slot, preventing standard multi-unit transfers.

To maintain routing freedom, only use an empty tube as temporary storage if you can clear it back out within two or three moves, or if you are committing at least two matching units that will form a finished bottle shortly.

Endgame: Locking Completed Bottles

The puzzle opens up significantly once you lock your first bottle. Filling a bottle with four matching units permanently completes that color, locking the container and removing it from active play.

Identify the color with the highest number of accessible segments across the board.
Route all matching units of that color into a single bottle until it reaches the four-unit cap.
Use the newly vacated tube space to unstack remaining single-layer blocks from mixed columns.
Consolidate the next available color into its permanent tube.
Cycle through the remaining colors one by one until all tubes are uniformly sorted.
