To sort bottles according to the game "Collect," follow these steps:

1. Identify and Group Bottles by Color: Start by examining the bottles available on the screen. Your goal is to find and group three bottles of the same color together.

2. Match Three Bottles: Drag and drop the bottles to align them so that three of the same color are next to each other. This can be done horizontally or vertically.

3. Automatic Collection: Once you successfully match three bottles of the same color, they will automatically be collected into a box and removed from the play area.

4. Continue Sorting: Keep sorting and matching other bottles of the same color to continue the process. The game will keep going until you run out of moves or complete the level's objective.

Remember, the key is to be strategic in your moves to ensure you can create as many matches as possible within the constraints of the game.
