were worth $50, $100, or $200 if they appeared in one, two, or all three windows, respectively. A pair without a joker, if chosen, was played for $100. A "natural triple" (three of a kind with no jokers) required the contestant to answer a question in that category for $200. In addition, beginning in 1974, spinning a natural triple awarded a bonus, which the contestant kept whether or not they answered the question correctly or won the game. The bonus initially consisted of a single prize worth approximately $300-$500, but by late 1983, it had been changed to a jackpot of prizes that increased in value after every game in which it was not won. Special categories Mystery: This category was always played for double normal value ($100 as a single, $200 as a pair or $400 as a triple). The contestant selected one of seven numbered question cards in a rack mounted on the host's podium; each card was in a different category, none of which were the same as any of the other four in play. Pot Luck / Grab Bag: Questions could be about any topic, not necessarily one of the other four in play. Stumpers: This category consisted of questions that were missed by both contestants in previous episodes. After the host read the question, the contestant could choose to hear the two previous wrong answers and play for the normal value, or decline the help and play for double value. When first introduced, this category consisted merely of straightforward questions and was played for an extra $100. Fast Forward: The contestant could answer multiple questions if desired, each worth the amount spun, and stop after any correct answer. Missing a question forfeited all money earned on that turn and gave the opponent a chance to claim the money for only that question. Bid: The contestant had to decide at the outset how many questions they wanted, with a minimum of two. Completing the bid awarded the full value of all questions answered (for example, three questions at $100 each awarded $300), but a miss gave the opponent a chance to take control with a correct answer and complete the bid themself. If the champion selected this category but did not bid enough questions to tie or surpass a challenger who had already reached $500, the champion immediately forfeited the game.
