Rules of a game
When you play football, chess [ ], you always need to know the rules. Why? Because without the rules, the game does not make sense! Of course, you can break the rules when no one sees, [ ]. For example, you can harm yourself or others.

And even if you follow all of them, still be very careful [ ]!
