- BASEBALL (all) – five innings of play. If the home team is leading, the game is official after 4 ½ innings (this will include softball). Thereafter, if a game is called or suspended, the winner is determined by the score after the last full inning, unless the home team scores to tie or take the lead in the bottom half of the inning, in which case the winner is determined by the score at the time the game is called.
- FOOTBALL (pro and college) – 55 minutes of play.
- BASKETBALL (US pro) – 43 minutes of play; (US College, WNBA, NBA Summer League, European) – 35 minutes of play.
- HOCKEY (all) – 55 minutes of play. (Non-US) – 60 minutes of play.
- GOLF – the results are official for wagering purposed provided that at least one round has been completed by all players in the field and a winner is declared by the tournament’s governing body.
- MOTOR RACING – All wagers will be settled according to the unofficial results reported immediately after the conclusion of the race by the governing organization. Any changes to the finishing order that occurs based on appeals, penalties or scoring malfunctions after the race has concluded, will be not be recognized.

Other Sports Rules
Wagers and proposition bets are offered to patrons and settled throughout the duration of games and events. Patrons are advised to check the individual sports rules sections for information on how wagers are settled as Minimum Length of Play rules do not relate to all wagers offered to Patrons.
For events where all participants are not listed and there is not a Field option, all bets are action. If a customer wishes to request BetMGM to offer lines on a new participant, then they can do so by contacting Customer Service. Where possible BetMGM will do so within a reasonable timeframe.
Dead Heat Rule
A dead heat is when two or more selections tie for a given position. In racing events (Motor Racing or Athletics for example), it could be due to both competitors crossing the line at the exact same time and the judge is unable to separate them. In other events, such as Golf, a dead heat occurs when players have scored the exact same score and are therefore classified in a joint position such as joint second place.
In a dead heat for first place, the stake money on a winning selection is divided by the number of winners in a dead heat. The full odds are then paid to the divided stake with the remainder of the money being lost.
For example: Kurt Busch and Denny Hamlin have dead heated for first place in a NASCAR race. If you backed either of these drivers, you would be paid half of your stake (MGM Grand Detroit pays out half the stake for both selections). Therefore:
$100 on Kurt Busch at +100 = Half Stake $100 = $50 at +100 = $100 returns.
$100 on Denny Hamlin at +800 = Half stake $100 = $50 at +800 = $450 returns.
Multi-selection Dead Heats
If there is a dead heat between multiple competitors, the following calculation applies:
The number of positions tied for, divided by the number of players tied in that position.
1 Brooks Koepka
T2 Tommy Fleetwood
T2 Tiger Woods
T4 Justin Rose
T4 Jordan Spieth
T4 Rickie Fowler
T4 Dustin Johnson
T4 Rory McIlroy
In this scenario there are two (2) players in a dead heat for second place, and five (5) players in a dead heat for fourth place. If you had picked a player to finish in the Top five, then those who finished tied for second place are both winners. Your full stake would then be paid out at full odds. However, if you had picked any of the players who finished tied for fourth place then those wagers would be settled differently. There are five (5) players in a dead heat for two (2) positions (fourth and fifth) and therefore you would be paid at 2/5 (two-fifths) of the stake.
For example, if you had $100 on Dustin Johnson Top 5 Finish at +200, your bet would be settled as follows:
- $100 on Dustin Johnson = 5 players tied for 2 positions = 2/5 (two-fifths) stake
- 2/5 of $100 = $40 at +200 = $120 returns
Calculations for Wager Types
a. Moneyline payoff: The money line is expressed as a 3 or 4 digit number. For example, -200 means a player must bet $200 for every $100 they wish to win, and multiples thereof. Or, +120 means a player will win $120 for every $100 bet.
b. Point spread payoff: Calculations for wager types are as follows: The spread line is expressed as a 3 digit number. For example, -110 means a player must bet $110 for every $100 they wish to win, and multiples thereof. Or, +110 means a player will win $110 for every $100 bet.
