1. Open the game and tap on the level you want to play. Each level presents a set of glass bottles filled with layers of different colored water.

2. Analyze the bottles and identify bottles with the same-colored water on top to begin sorting.

3. Tap on a bottle to select it, then tap on another bottle where you want to pour the top layer of colored water.

4. You can only pour water into another bottle if the top color of both bottles is the same and the receiving bottle has enough space.

5. Continue pouring water between bottles to group all water of the same color into individual bottles.

6. You cannot pour water if the rules are not met, so plan your moves carefully to avoid getting stuck.

7. If you find yourself stuck, you can restart the level at any time by tapping the restart button.

8. Use the hint or add a new bottle if available to help you solve difficult levels.

9. Complete the level when each bottle contains water of only one color or is completely empty.
