What are the summoning rules of Yu Gi Oh?

Answer:
Each card has a certain amount of stars at the top. 4 or less stars means that you can summon without a tribute which means to sacrifice a card. 5 stars means to sacrifice 1 monster. 6+ means to sacrifice 2 monsters. These rules apply, unless stated otherwise on a card.
