Observe the level carefully, try different strategies, try to learn many times and so on.

1. Observe the level carefully: carefully observe the elements, rules and tips in the level to ensure that you have a clear understanding of the requirements and objectives of the game.

2. Try different strategies: if one method fails, you can try other strategies and ideas. Sometimes it is necessary to use different skills and combinations flexibly to solve problems.
