Abstract: Some embodiments include a fantasy sports game. In some embodiments, an expected performance value may be determined. In some embodiments, a same player may appear multiple times in a team. Various other embodiments are described.

Abstract: Methods and systems are provided for managing a wagering system. In one exemplary embodiment, state information of a live event such as a sports game may be received in real time. During the event, a plurality of possible future states of the event and their associated probabilities (and odds) may be determined based on the state information, historical information, and current in-game information. A betting market is created for betting on the possible future states at determined odds. The betting market is closed, and winning and losing bets are resolved based on updated state information.

Abstract: Techniques for creating and managing wagers on possible states within a live event, such as possible outcomes of subparts of a sporting event or other possible occurrences within the event. An initial state and multiple possible future states of a performance parameter of the event are determined based on state information of the event. A betting market may be created by determining probabilities and odds for the possible future states. Bets may be made on the possible future states via a touch-sensitive display. A payout may be made to a winner who selects a possible future state that actually occurs.

Abstract: According to various systems and methods, financial indicators may be used as random number generators to determine variables, such as numbers and cards, for various games, including casino-style games like roulette and poker. Players may place wagers relating to one or more game variables, such as one or more cards, hands, a roulette wheel spin, a lottery number, or other variable or outcome of a game. After bets are received, one or more random numbers may be determined based on one or more financial indicators, such as a least significant digit of the price or value of a financial instrument, index, or financial metric at a specific time. The random number(s) may be used to determine game variables, such as a winning lottery number, slot reel values, or numbers and suits of cards dealt. In some embodiments, players may select one or more financial instruments or indicators that will be used to resolve one or more game variables.

Abstract: A user may purchase an option to cancel a wager in exchange for a refund amount. In purchasing the option, the user may select an exercise time from a plurality of exercise times, each exercise time having an associated price, which price may be the price of the option. The refund amount associated with each exercise time may be the same amount. Responsive to a user exercising a purchased option, a determination may be made as to whether the time of exercise is at least prior to the selected exercise time. If so, the wager may be canceled in exchange for the refund amount.

Abstract: Methods and systems are provided herewith for managing a wagering system. In one exemplary embodiment, a stream of state information of a live sporting event is received in real time. A computer processor determines an initial state and a plurality of possible future states of a first performance parameter of the live sporting event based on the stream of state information. After a beginning of the game and before the start of the event, a probability of occurrence is calculated for at least one of the plurality of possible future states of the first performance parameter based on historical data related to the first performance parameter. The plurality of possible future states are mutually exclusive from one another. During an initial state of the first performance parameter, a signal operative to open a first market for betting on the at least one of the plurality of possible future states is transmitted. The first market comprises betting odds based on the calculated probability of occurrence.
