Contestants will compete in a quiz competition played 24 hours a day for 1,000,000 seconds, or about eleven and a half days. Money is made by sitting in the "Money Chair" and answering multiple-choice trivia questions against a series of challengers in head-to-head quiz bouts. Although commercials bill the winnings as $10 per second spent in the chair—or $36,000 per hour or $864,000 for every day—the rate is actually $1 per tenth of a second; money accumulates at a constant rate, even when matches are not being played. Contestants in the chair earn money until they are defeated by a challenger, who replaces the occupant of the chair. Each bout lasts a short period of time (300 seconds during prime time). Contestants have only five seconds to answer a question; questions start at one point, and the value increases by one point every 100 seconds (starting with the next question after that 100 seconds elapses). In addition, a contestant can "double" their opponent, challenging them to answer for double points (with an incorrect answer giving double points to the doubling player), although an opponent can "double back" for quadruple points either way; if doubled back, the contestant is forced to answer. Each contestant may double as often as they wish during the bout. The contestant who accumulates more points wins the bout and either retains the Money Chair or replaces the contestant who was in the Money Chair at the start of the bout. If there is a tie between the two contestants, a tie-breaker question is asked. If both contestants answer the tie-breaker question wrong, the contestant who accumulated more money wins the bout.
The second bout of each episode features a "Line Jumper," a player who qualified for the show by achieving a sufficiently high score on the
Million Second Quiz app, bypassing the normal tryout process.
During the game, the top four players who have spent the longest time in the Money Chair, and therefore accumulated the largest amounts of money up to that point in the game, will live next to the hourglass in "Winners' Row". They will try to survive there until the million seconds are up, but other contestants will displace them if they achieve longer runs in the chair. In addition, the last bout of each of the first nine prime time episode is the "Winner's Defense" bout. In the Winner's Defense, the current "Power Player," i.e., the player with the most winnings credited, chooses one of the four players currently on Winners' Row to face the player currently in the Money Chair (and may choose himself or herself). Those two players compete in a 400-second bout; the winner of that bout claims both players' total winnings, and takes or keeps the Money Chair, while the loser is eliminated.
Money Chair challengers and players eliminated (but not displaced) from Winners' Row lose any winnings they have accumulated. Eliminated players (including players displaced from Winner's Row) may try out again and possibly win their way back into the Money Chair.
When the countdown clock hits zero, the four contestants on Winners' Row who have made it to the end, plus the current occupant of the Money Chair, will keep all of their credited winnings and battle it out in a series of knockout bouts for a $2,000,000 additional prize,[SUP]
