The facts are presented in four rounds (4 facts, then 3, then 2, then 1), each with a category that ties them together. Numbers range from the very low (including single digits) to the very high (hundreds of millions, or even billions). Things get progressively harder the more numbers there are, as the contestant must slide each fact in between several others as the game progresses. If a contestant incorrectly orders the facts, they're replaced by a new contestant.
In season 2, the format changed to a more standard competition: Two players (each playing for a section of the studio audience) play three rounds of fact-stacking for various dollar amounts. The winner then goes on to a Bonus Round to play for $10,000 (for both themselves and their section of the audience).

- All or Nothing: Played with in season 1. Though the contestant (and selected audience members) keeps the first prize won no matter what, if the contestant makes it to the final fact (worth $10,000 and two cars, one for the contestant and one for one lucky audience member), they're given the category and the chance to walk away. If they continue and lose, they and the audience lose all their prizes except the first one.
- The Announcer: Kira Soltanovich, best known for being on the Oxygen show Girls Behaving Badly. She gets plenty of screen time and "fires up" the win watches to see who gets picked to be a contestant and for prizes. Ditched in Season 2.
- Bonus Round: The Final Five in season 2. Five facts, five numbers. Match the facts to their numbers correctly in 45 seconds for $20,000, 10 for the contestant and 10 split between their section. The contestant may lock in once before the 45 seconds are up to check how many they have right.
- Catchphrase: "Show it to us!" The first season also had "Fire up the win watches!"
- "Show it to us!" is almost a Forced Meme, as GSN promos it back-to-back with Family Feud and their own Catchphrase, "Survey said!"
- Color-Coded Multiplayer: Used in season 2. One contestant played for the gold section of the audience, the other played for the purple section.
- Consolation Prize: In season 1, if the contestant wins the first prize, they (and the selected audience members) get to keep it, no matter what else happens.
- Game Show Host: Donald Faison, actor best known for Clueless and Scrubs.
- Golden Snitch: In Season 2, each player can win $1,000 in the first 2 rounds. The dollar amounts for the last 4 clues (which can go to either player) are 500-600-700-1,750. Only if one player takes the first three facts and was either tied or ahead of the other player does the last fact not decide the game.
- Let's Just See What WOULD Have Happened: In season 1, if the contestant declines to play for the final prize, Don would have them play out the final round anyway. Amazingly, this only came into play once.
- Retool: The second season introduced a completely different logo, set, and format. It also removed Kira entirely.
- Shout-Out: Several involving Donald Faison:
- One fact was "Number of years since the movie Clueless opened in theaters". Don said he was 21 when he made the film, and he's in his early 40s, so he knows the answer.
- Another fact was "Number of episodes of the TV show Scrubs. Turns out the contestant was a big fan of the show...and of course said Don was her favorite actor (and this was heavily used in advertisements in the leadup to the premiere).
- Studio Audience: Where the contestants were drawn from in season 1. Audience members were also picked to win prizes, and often gave the contestant advice about certain facts. In season 2, each section is represented by a contestant much like Tattletales, and split money equal to what their contestant wins.
