First you need at least a deck of 60 cards with a choice of monster,magic,trap,or spell.Now you need to draw a card from your deck and depending on what it is then you need to make it a face down or put it in play,their are 4 ways of putting your card in play depending on what it is.The first way is Attack mode where you can use the monster in play to wipe out your opponents monster if your monster is stronger.The second way is Deffence mode that is where you can defend your monster if your opponents monster is stronger and the best part is that nothing happens to your life points when your monster is defended.The third way is Equipped mode where you can equip that monster while it is in play but you can only equip your monster with magic or spell.The fourth way is Element mode that is where your can add and fuse other elements with monsters by using magic cards that allow it.Now let me tell you about combination's this can only be taken place when you have certain elements or type's and magic,spell.

thats right meet me on comment wall and we can get started up to 6 players can play so se ya there.
