A flip refers to a card being changed from face-down to face-up or vice versa.

A monster may be flipped by Flip Summoning it. In this case you change the monster from face-down Defense Position (or Attack Position) to face-up Attack Position.

If a face-down monster is attacked, it is flipped face-up and maintains its battle position. Monsters can also be flipped by the effects of other cards. Neither of these methods are considered to be a Flip Summon.

There is no rule that allows players to flip face-up monsters face-down. This can only be done by the effects of certain cards.

Some monsters, known as Flip Effect Monsters, effect activate when they are flipped face-up.
