The main way monsters come to the field is by being normal summoned.
 How do I normal summon?
During your main phase 1 or main phase 2, play a monster from your hand face up or set it face-down.
- All normal summons must be in face up attack position or face down defense position
- Attack position is always vertical and defense position is always horizontal.
 What do the stars have to do with it?
The stars are the level of the monster. The number of stars determine the number of tributes required to normal summon a monster.
 No tributes
Monsters with levels 1 through 4 require no tribute to be normal summoned.
 One tribute
Monsters level 5 and 6 require one tribute in order to be normal summoned.
 Two tributes
Monsters with a level of 7 or above require two monsters in order to be normal summoned.
 Tribute summoning?
Tribute summoning is simply normal summoning a monster that requires a tribute.
 How do I tribute summon? What happens?
You place the monster or monsters that are tributes in the graveyard. After this, you play the monster from your hand like normal.
 How often and when can I normal summon?
You may only do this once per turn during one of your main phases unless a card effect states otherwise. An example of one of these cards is Double Summon, which allows you to summon once more during the turn it is played.
