Card breaks only apply to the card-based battle system of Kingdom Hearts: Chain of Memories and Kingdom Hearts Re: Chain of Memories. All cards have a certain value, which may be nullified, or "broken", by a card of equal or greater value. Cards may also be broken by another card with a value of zero. Most often this is used to break sleights (three cards stocked together to produce certain combat moves or a higher card value). However, neither combatant will attack if both play with equal numbered cards, which results to a very quick temporal stun for the one who played the card first.
