Shows like Play Your Cards Right

Two couples (two single players during the first series) alternated who went first on each question. The questions were based on surveys of 100 people. The first couple would guess how many of the 100 gave a certain answer to the question, and the second would guess whether the actual number was higher or lower than the other couple's guess. (If the first couple guessed exactly the number of people, they would win a case of champagne, as opposed to a cash bonus depending on type of question on the US versions ($100 for 10-person surveys with another $100 split among the panel, $500 for 100-person surveys or general knowledge questions.) Whoever was correct gained control of the cards.
