Keep this card. If the player with this card is given another card with the same number, discard Second Chance and the duplicate number card. A player may only have one Second Chance card in front of them at a time. If they are dealt another Second Chance card, they then choose another active player to give it to. If there are no other active players or if everyone else already has one, then discard the Second Chance card. Additionally, all Second Chance cards get discarded at the end of a round even if they were never used. This could happen if the player who drew it got a Freeze card played on them or if they successfully Flip 7 Number cards.
