How to study
Try solving before asking for a hint. If you look at the solution, explain in your own words what changes after removal. Try again and take that idea into a game.
The key to winning
A single line can be broken. Build several lines without a tile whose removal destroys them all. Before attacking, check whether you must remove a specific tile to stay in the game.
