Now in order to play anything in class, the first thing you need to do is to check the rules and regulations of your school. You need to check if you are allowed to carry and items with which to play in class, and if you can actually use them in class, or if they are reserved to be used only in the break hours.
Once you have all this information and if you are allowed to play in class, then you can even think about going on and trying to play in your class. This is because if you aren't allowed to play in class, there is no point in even trying.
What you need to do, is to figure out just how many people are going to be playing with you. You need to do this before you start playing so that you can set up a lay out, which would determine just how you are supposed to be playing.
Now once you have the number of people listed down, go ahead and join as many desks together as you can. This is going to give you a much bigger area to play on, which is going to make it a lot easier for everyone and will ensure that not much cheating takes place.
The last thing you need to do is to go ahead and appoint a referee. This referee is important for all games played in classes, since just about everyone cheats when they play in school. The job of this referee is to ensure that no cheating takes place and to make sure that the game flows smoothly and that the deck is shuffled and distributed properly as well.
