After any correct guess, a couple could "freeze", which would protect their cards. A marker would be placed by a dealer beside the frozen card, which meant that on the next question, a wrong guess on their cards would put them back no further than where they froze. This was usually done when the card shown was of a middle rank, such as a seven, eight or nine. After a couple froze their cards, play would continue to the next question. Should the couple regain control of the board on a correct question, they will be allowed to change the frozen card (due to it now being the card the couple would start on.).
