To play "Cookie Crush 3", follow these steps:

Start a new game: Click on the "Play" button to start a new game.

Look at the board: You will be presented with a board filled with different types of cookies.

Match cookies: Your task is to match at least three cookies of the same type by swapping them either horizontally or vertically. You can swap any two adjacent cookies on the board. The matched cookies will then disappear, and new cookies will drop down from the top to fill in the gaps.

Use power-ups: There are special cookies that can clear entire rows, columns, or areas on the board. These cookies can be created by matching more than three cookies at once, or by using power-ups that can be earned by matching certain types of cookies.

Complete challenge levels: There are special challenge levels that offer bonus rewards and power-ups to help you progress even further. These challenge levels can be unlocked by collecting stars, which are earned by completing regular levels with a high score.

Check your score: At the end of each level, you will receive a score based on the number of cookies you matched and the moves you used. You can then compare your score with your friends and other players on the leaderboard.
