About this game

🧪 FLOW SORT: COLOR TUBE PUZZLE

Pour colorful liquids from tube to tube and sort every color to solve the puzzle. In this liquid sort challenge, a tube can only receive liquid that matches its current top color — or accept any color if it's empty. Your goal: fill every tube with a single color from bottom to top.

Simple rules. Deep logic. Satisfying payoff.

🎮 HOW TO PLAY

- Tap a tube to select it
- Tap another tube to pour the liquid
- You can pour only onto the same color or into an empty tube
- Full tubes cannot receive more liquid
- Match all colors — clear every tube — win the level
