About this game

Tube Sort is a calm, satisfying water-sort puzzle from NovaArcade.

Tap a glass tube, pour its top color into another valid tube, and keep going until every tube is empty or filled with a single color. Crystal-clear pours, a soft luminous lab atmosphere, and levels that are always solvable — no unfair boards.

Features
• Tap to select, tap to pour — one finger, offline
• Smooth glass pour animations
• Undo when you mis-pour (limited charges)
• Stuck? One-tap hint (optional rewarded)
• 80+ validated levels with a rising difficulty curve
• Daily challenge (same puzzle worldwide each UTC day)
• Music, SFX, and haptics you control
• Colorblind-friendly patterns

Remove ads anytime with a one-time purchase. Short sessions. Pure pour skill.
Pour colors in glass tubes. Sort every rack. Stuck? One-tap hint.

What’s new

Sunny Lab is the new default look — warm cream glass, easier to read.

The Rescue
Save friends against a 90-second clock. Five chapters to start: Fin, Sal, Pico, Luma, and Nib. More friends on the way.

Formula Lab
A second 40-level flask track. Open it with gems, or finish The Lab.

The Lab
Classic pours with Lab Pressure — the rack lives between pours. Vent it, or it drips.

Gems, extra bottles, and untie-a-knot when a hard board locks up. Levels still unlock one at a time.
