General Sports Book Rules

  1. BetMGM reserves the right to refuse any wager, delete, or limit selections prior to the acceptance of any wager.
  2. BetMGM will determine minimum and maximum wager amounts per patron on all events to include all periods, segments, propositions, and future book wagers.  Maximum payouts limits shall only be established through limiting the amount wagered and cannot be applied to reduce a winning wager amount.
  3. BetMGM mobile wagering application displays real time lines, current odds, and potential payouts when placing wagers. Patrons will be prompted with a confirmation message that selections are correct prior to the selection of the ‘place wagers’ button. Line change notifications may occur at any time during the wager placement process.  The system by default accepts more favorable odds and the player must acknowledge or decline any less favorable odds changes.  This setting can be adjusted by the player to accept all odds changes for fastest play or acknowledge all odds changes for a more conscientious play.
  4. For online wagers, if a patron made an inadvertent bet in patron's account dueto an error (e.g., inadvertent multiple identical bets), patron must inform BetMGM within 15 minutes of any bet patron placed for BetMGM to consider appropriate adjustments to be made to patron's account.
  5. Wagers accepted will not be able to be changed or voided by the player upon confirmation of the successfully placed wager.
