Quick answers to common questions
This site shows how each contestant's chances of winning change throughout a Jeopardy game. Games are updated overnight and cover 20+ years of Jeopardy games.
All regular season games dating back to 2002. Postseason is not included for now.
The probabilities are determined by a machine learning model that prices in the returning champion's stats, current round and questions remaining, daily doubles remaining on the board, which player has control of the board, current scores, and in-game player statistics.
The Daily Double Analysis page shows whether contestants made optimal wagers on Daily Doubles. Optimal wagers are determined by the changes in win probability if the player gets their question right or wrong for a given wager size, and calculates their expected change in win probability for a given get rate of the question. The process is roughly similar to the 4th down conversion calculators in football.
Visit the DD Analysis page and select any game using the season and date dropdowns. Choose a specific Daily Double from the list, and you'll see a chart showing the optimal wager percentage for different get rates. The player's actual wager is shown as a green line, and historical average get rates are shown in red. This reveals whether they wagered too much, too little, or just right.
Use the search bar at the top of the main page. Type any contestant's name (like "Ken Jennings" or "Amy Schneider") to see all their games. Click any game to view its chart.
No. The probabilities are calculated before Final Jeopardy wagers are revealed. This is why you'll sometimes see a player with a high probability who ultimately loses due to a surprising wager.
The Excitement Index Articles is a numerical rating to indicate how exciting a game of Jeopardy is to watch. This rating is comprised of 6 components capturing the following facets of a Jeopardy game: volatility of win probability (with higher weight of late game volatility versus early game), lead changes, the strength of upset of the defending champion, the aggressiveness of daily double wagering, the suspense going into Final Jeopardy, and the total scoring of the game.
The default weights for the Excitement Index are to weight all components equally. If you want to set your own custom weights for the Excitement Index and/or see the components of each game, you can do so at our Custom Rankings page.
