Kandace Kuehl was the co-host for the first three shows and was then replaced afterward with the 1983 Miss USA winner Julie Hayek.

Kline and his staff broke away from the company in protest against changes made by co-owner Dan Enright shortly thereafter.

The first couple to solve two puzzles won the game and advanced to the Prize Vault in an attempt to break the bank.

The maximum potential time that a couple could accumulate was 540 seconds, obtained by answering every question correctly on the first two puzzles, solving one of them but not the other, and then winning the tiebreaker.

The winning couple used their accumulated time to win prizes and "bank cards" by completing various stunts, such as answering riddles, identifying smells or noises while blindfolded, reciting a tongue twister, or hanging laundry on a clothesline while a large fan blew wind over them.

The couple began the round while standing at a podium equipped with a card reader slot and chose a stunt, and one or both members (depending on the rules) ran to that station to play it.

If the couple chose this stunt, an alarm sounded and one member had to run to the device and press a button to stop it, taking the displayed number of cards from a separate set of five.

[3] Cards acquired by completing stunts had to be inserted into the slot on the podium before time ran out in order for the couple to keep them and win the associated prizes.

During this portion of the round, the host would offer cash and/or prizes to surrender any untested cards after each failure to break the bank and would test them in the slot if the couple accepted.

Couples remained on the show until they lost the main game, accrued at least $75,000 in total winnings, or played the Prize Vault five times.

One clue was revealed at a time, starting at the top right and proceeding clockwise around the board, and the couple could offer one guess after each.

After finding any card that awarded cash or a prize, the couple could opt to stop playing for the day if they had not yet used all of their choices, with no cash/prizes offered by the host to do so as in the first format.

In addition, a kids version of the series titled En route pour l'aventure ("On the road to adventure"), also hosted by Michel Robbe, aired from 1988 to 1991.
