Based on the game show's original (1971-73) format, the emcee chooses four prizes and places three sets of three cards in the board; the last prize only has two cards put in, along with a "No Match" card.
Three categories are shown, and the players bid on how many true/false questions (1-4) they can answer. High bid plays the questions, while ties cancel out. The total number from the bids is multiplied by $10 and becomes the prize for the round (for example, 4-3-2 would be worth $90), although choosing a Double Pot category doubles the amount available (maximum of $220). Once a player answers a set of questions correctly and has at least $140 (the show required just $90), s/he may try to go to the board.
The board contains four colored rows (Red-Green-Yellow-Blue) and three amounts ($20-$30-$40); the player in control calls out the money and color (i.e., "Forty on the Red") and can buy as many boxes as possible until either matching or not having enough to buy appropriately, with one catch: a column is closed when three of its boxes are picked. Matching awards that prize's value to the player's score, and the first to $5,000 ($4,000 if only two people are playing the questions with an emcee) wins.
If the first three picks of a game match, that player wins the prize and a jackpot which starts at $100 and increases by $100 each time it is not won.
From April 1973 until the show's end in June 1974, the format changed to matching pictures; the first player to get three matches won the game and $5,000 in prizes.
