They compete to answer a series of general knowledge questions and earn one of four slots in the final, using their numbers to set the day's jackpot and then trying to win equal shares of it.
If the contestant selects both correct answers, they qualify for a Battle and sit out the rest of the round; if not, the host asks a new toss-up.
When time runs out, the contestant with the highest score advances to the Final and may place their number in any open slot on the board (thousands, hundreds, tens, units) to determine the day's jackpot.
After the fourth Battle, both the defeated contestants and the one who did not qualify for it are eliminated from the game, and the Final is then played.
All four contestants win equal shares of the jackpot if they each meet their target without running out of time, or nothing if the clock reaches zero at any point.
