      • Otherwise than in accordance with the applicable laws.
      • At odds that are materially different from those available in the general betting industry at the time the bet was accepted, whereby TwinSpires will use a majority of betting industry operators, to determine whether odds offered were “materially different”.
      • At odds which reflect an incorrect score, standing or ranking situation, including where incorrect odds are offered, as a result of any errors or omissions made in respect of the announcing, publishing, or reporting of a score, standing or ranking situation.
      • At incorrect odds where it is clear that the actual chances of the event occurring at the time the bet was accepted were materially different, or
      • That the bet has been placed by someone other than the Patron (including where someone has gained access to the Patrons’ account) or where the Patron is victim of fraudulent activity.
  • “Influence Betting” is an act, prohibited by TwinSpires, where an Patron, or parties acting in association with an Patron, can influence, or have influenced, the outcome of a match or an event – directly or indirectly.
  • “Syndicate Betting” is an act, prohibited by TwinSpires, where Patrons act together to place a bet or series of bets on the same event or competition, or when an Patron places a bet on behalf, or for the intended benefit, of another individual or other individuals. Where there is evidence of Patrons acting together in this manner TwinSpires reserves the right to make the relevant bets void and/or withhold payment of returns pending the outcome of subsequent investigations to determine whether (in TwinSpires’ sole opinion), Syndicate Betting has taken place.

3. Bet Acceptance

  • Each bet constitutes a legally binding betting contract between the Patron and TwinSpires. The formation of such betting contract requires the following phases:
    • The advertisement of a betting market.
    • The request to place a bet or wager on the betting market by the Patron.
    • The acceptance and confirmation of the bet or wager by TwinSpires.A bet is not valid until it is validated. In cases of uncertainty about the validity of a bet, it is the Patron’s responsibility to check the bet slip or contact a customer service representative.
  • A bet is not accepted and confirmed until it shows in the Patron’s bet history. Once it does, the contract will be considered duly formed. In cases of uncertainty about whether a bet has been accepted, the Patron is requested to check the open (pending) bets or contact Customer Service for confirmation. No bet or wager will be considered as completed unless confirmed via the Patron’s bet history or Customer services.
    Unless accepted in Error, once accepted, a bet cannot be withdrawn by the Patron. It is the responsibility of the Patron to ensure details of the bets placed are correct.
  • Should a dispute arise about the acceptance (or lack thereof) of any bet, or the time at which any bet was placed, TwinSpires’ transaction log database will be the ultimate authority in determining such matters.
  • TwinSpires may refuse to accept any bets or wagers at any time and for any reason including in order to:
    • Preserve the viability of the offered market (for example, without limitation, in relation to events where there is an extraordinary or unbalanced number of bets on the same market).
    • Protect the Patron (e.g., without limitation, in relation to the event in which the Patron display pathological behaviour and refuse to self-exclude).
    • Protect other users (e.g., without limitation, in connection with the event in which the Patron have a betting pattern that could adversely affect the regular betting activity of other users).
    • To protect TwinSpires (for example, without limitation, in the event that the Patron exhibits money laundering, collusive or fraudulent behaviour, we suspect that Patron is using a third party’s account, is allowing a third party to use the account, or is using automated means, bots, software or similar means, or engaging in arbitrage).
  • TwinSpires, depending on the level of risk, instead of refusing a bet or a wager, may accept the bet request placed by the Patron up to a certain amount thereof.

4. Betting and Payout Limitations

  • In order to guarantee the viability of each market, to avoid potential cases of fraud and match-fixing, and to be able to make a correct estimate of the risk involved in each product offered, TwinSpires will limit the net payout (the payout after the stake has been deducted) on any bet or combination of bets by one Patron at an amount determined by the event risk to TwinSpires for any bets placed or settled within a 24-hour timeframe.
  • TwinSpires determines that the minimum bet stake accepted will be $1 and the maximum stake accepted will be an amount determined by the event risk to TwinSpires, notwithstanding potential exceptions, dependent on the markets and bets proposed.
  • TwinSpires reserves the right to decline, all, or part of, any bet requested. This includes the possibility that a “System bet” as defined in <Section B, Para 4> is not accepted in full, either in terms of stakes or combinations included in said “System bet”. All bets placed through any TwinSpires platform, also including bets requesting manual approval, may be subject to a time delay prior to acceptance, the length of which may vary.
  • All odds offered are subject to variation. Such fluctuation is determined by TwinSpires Bets are accepted only at the odds available in the betting grid, at the time the bet was accepted by TwinSpires, irrespective of any other claim or previous publication present on the website or any other media detailing otherwise.
  • All payout calculations when settling bets will be done based on Decimal odds, irrespective of any other format displayed/chosen at time of bet placement.

5. Cancellation (Voiding) of Bets

  • A bet can be declared void, under the circumstances described in clause 3 below. If a bet is voided, it will be settled with odds of 1.00.
  • A bet made as an accumulative bet shall remain valid, notwithstanding a match or an event which is part of the accumulative bet being void.
  • TwinSpires reserves the right, to declare a bet void, totally or partially, if any of the following, or similar, circumstances have occurred:
    • Bets have been offered or placed due to an Error and/or at odds which significantly differ from those currently present elsewhere in the betting industry market (see Section A, Para 2, clause 1)
    • Bets placed while the website was encountering technical problems, that would otherwise not have been accepted;
    • Influence Betting;
    • Syndicate Betting;
    • A result has been affected by criminal actions – directly or indirectly;
    • A public announcement has occurred in relation to the bet which significantly alters the odds.
    • A bet has been offered on the relevant market in breach of the gambling regulation in the specific jurisdiction. If TwinSpires accepts a wager, TwinSpires shall pay the full amount for a winning wager. However, TwinSpires may obtain an approval from the Mississippi Gaming Commission to void any bets that have been offered or placed.
  • Past-posting and other cancellations: While TwinSpires employs its most reasonable endeavours to ensure the best user-experience, should a market be available for betting when it should have been removed or else with incorrect odds, TwinSpires reserves the right to void all bets accepted within said circumstances in accordance with <Section A, Para 5.3>. Similar situations include, but are not limited to:
    • ‘Pre-match’ bets placed/accepted after the event has started;
    • ‘Live’ bets placed/accepted at incorrect odds due to delayed or failing ‘Live’ coverage, or on odds which represented a different score than the actual;
    • Bets placed following the last instance that a participant/outcome had any chance to influence the match/event scoring applicable to the relevant market and an eventual withdrawal/disqualification/cancellation/format change or anything which precludes the ability of the applicable participant/outcome to influence said scoring will be declared void;
    • Bets placed with odds which do not reflect that a related event was underway and where conditions could have been altered in a direct and indisputable way, or else after an event which could normally be deemed as leading to the outcome is happening or has happened already.
  • Related contingencies: Unless placed via TwinSpires’ in-event combination functionality, or offered explicitly as a specific offering, TwinSpires prohibits accumulator bets that include two or more outcomes which might turn out to be related (e.g. Team X to become champions and Player Y to be Top Goal Scorer in the same league). Although TwinSpires takes all necessary steps to prevent such possibilities, in the eventuality that this would happen, TwinSpires reserves the right, to declare void all parts of the accumulative bet which include the correlated outcomes whose odds are not indicative of the related contingency.
  • Bets can be voided regardless of whether the event has been settled or not.

6. Disclaimer and Priority

  • TwinSpires reserves the right, to adjust a Payout credited to an Patron’s balance if the Payout has been credited to the Account due to an Error.
  • In order to adjust any inaccuracy in the Patron’s balance following amounts credited due to Error, TwinSpires reserves the right to take any necessary action, without prior notice and within reasonable limits, to adjust the Patron’s balance through the reversal, amendment or cancellation, of any subsequent transaction on the Patron’s account.
  • These rules are applicable to all transactions with TwinSpires Sports Book and may be supplemented with other Rules. In the event of ambiguity, priority should be considered in the following order:
    • Rules and conditions published in conjunction with an offer and/or campaign.
    • Sport-Specific Rules.
    • General Sports Book rules.
  • Should unforeseen circumstances occur for which settlement is not covered explicitly by these rules TwinSpires reserves the right, to settle affected bets on an individual basis on the basis of equity, attaining itself to generally accepted betting norms, customs and definitions.
  • Any data provided or accessible in, from, or related to the Sports Book, may be used by the Patron for private, non-commercial use only and any use or attempted use of such data for commercial purposes is strictly prohibited.
