About this game

Spectrum Sort is a color-sorting puzzle where you turn chaos into order — one drop at a time.

• 25 handcrafted levels: Easy (1–10), Medium (11–20), Hard (21–25)
• Classic tube mechanics: pour liquids between tubes to stack or combine colors
• Color mixing: Red + Yellow = Orange, Red + Blue = Purple, Blue + Yellow = Green
• Filter tool: split a mixed layer and extract the last-added color into an empty tube
• Star rating: use fewer filters to earn more stars — 3 stars means filter master
• Undo last move, restart anytime, level select with unlock progression
• How to Play guide built into the app
• Fully playable offline — all levels bundled; no account or login required

How it works: tap a tube to select it, then tap another to pour. Different pure colors merge into a new shade. When stuck, use the Filter on a mixed tube and pour the separated color into an empty tube. Win when every non-empty tube holds exactly one pure color.

No ads, no sign-up, no pressure — a calm logic puzzle whenever you have a minute.
