Studio-based primetime format. Three pairs of contestants have to battle it out over a series of fast-paced rounds – filling the safe with prize money along the way. The final couple get the chance to unlock the safe, but only if they can press their buttons in sync at the end of 30 seconds. It’s not as easy as it sounds, though. With 30 seconds left, the finalists are separated from one another and the massive studio clock disappears from the set. With a single second margin of error, they have only their own internal clock to rely on if they are to have any chance of opening the safe and winning the prize money.
