1. Open it and select "Play" to start a new game.

2. You will see several containers of different colors filled with water.

3. The goal is to sort the water so that each container only has one color. To do this, you can pour the water from one container to another.

4. You can only pour water from a container that is full or partially filled, and you can only pour water into an empty container or a container that has the same color as the water you are pouring.

5. To pour water, tap and hold the container with the water you want to pour, and then drag your finger to the container you want to pour the water into.

6. As you progress through the levels, you will encounter more containers and more complex color patterns.

7. Pay attention to the number of moves you have left to complete the level. If you run out of moves, the level will end and you will have to try again.

8. Earn stars by completing the levels within a certain number of moves or by achieving certain goals, such as sorting the water into the containers in a specific order.

9. Use the stars you earn to unlock new levels and worlds, as well as to purchase additional moves if you need them.
