bet365 vs BetMGM: Compare Odds and Overtime Rules

A fourth-quarter total can cover different minutes at bet365 and BetMGM. That makes a bet365 vs BetMGM odds comparison a rules check before it becomes a payout calculation. A better-looking price can belong to a different bet.

The useful answer is market-specific: compare the same selection, period, and settlement terms, then choose the price that pays more for that outcome. This guide uses hypothetical prices throughout. They illustrate the arithmetic, and aren't live offers or evidence that either sportsbook routinely prices better.

Start the bet365 vs BetMGM comparison with the rules

There is a concrete football distinction to check. The heading on bet365's US football rules page says game lines, including second-half and fourth-quarter bets, include overtime unless stated otherwise.

BetMGM's football overtime explainer says second-half bets include overtime, while fourth-quarter wagers exclude it unless otherwise stated. Read the terms attached to your market and account before relying on either general description.

Imagine a fourth quarter produces seven points, followed by ten in overtime. An over 10.5 bet covering only the fourth quarter loses. An under 10.5 bet covering that quarter plus overtime also loses. Opposite labels have left a gap in coverage.

That example explains why a pair of attractive prices can fail as a hedge. Write down the period each ticket covers. If they differ, stop the comparison there. Our BetMGM and bet365 comparison page covers the broader account and app comparison; the price check here starts with the exact market.

Put matching prices into dollars

Once the rules match, use the same cash stake to compare returns. Suppose the same team to win is +120 on one screen and +110 on the other. A hypothetical $50 bet wins $60 at +120 or $55 at +110. Including the returned stake, that's $110 versus $105.

Positive American odds show profit on a $100 stake. Negative odds show the stake needed to win $100. For example, a $50 bet at -105 wins about $47.62; at -115 it wins about $43.48. The difference is about $4.14 on a winning ticket at those prices.

Attach the book names only after you have the current quotes in front of you. This calculation works whichever operator has the better number. Our line-shopping guide explains how comparing the same wager across accounts fits into a repeatable routine.

A higher payout still requires a winning selection. It tells you nothing by itself about how likely that team is to win.

Keep the spread separate from its price

A team at +3.5 points and -115 has a different winning condition from the same team at +3 and -105. The first ticket has the more expensive price, but a three-point defeat wins it. Under ordinary push rules, that same defeat returns the stake on +3 with no profit.

You therefore need to compare two fields: the points and the odds. Calling -105 cheaper is arithmetic. Deciding whether the extra half-point is worth paying for requires an estimate of how often it changes the result.

Use our guide to football key numbers for the scoring context. Keep your own comparison precise: same opponent, same event date, same period, and the same point threshold whenever you're isolating a price difference.

Test an apparent arbitrage with matching outcomes

Sometimes opposing prices let you divide a stake so either covered outcome returns more than the total committed. That's arbitrage. The condition matters: the outcomes must cover every possible settlement, with compatible rules.

Consider a purely hypothetical market with exactly two possible winning outcomes and no draw or push. Suppose each side is available at +110 at a different sportsbook. Converted to decimal odds, each price is 2.10, meaning the return includes 2.10 times the winning stake.

• Stake $50 on each side, committing $100 in total.
• The winning $50 ticket returns $105 at the odds shown.
• The other ticket returns $0, leaving $5 before any applicable costs or taxes.

The reciprocal prices add to about 95.24%: 1 divided by 2.10, twice. A sum below 100% is the arithmetic test for this fully covered setup. The $5 return above the $100 committed is 5%; that differs from the 4.76 percentage-point gap below 100%.

Our arbitrage percentage guide explains unequal stake splits. Recheck the accepted prices on both receipts. A changed quote, rejected second bet, account limit, or mismatched rule can leave you exposed to a loss. The football example above fails the coverage test before any arithmetic starts.

Save a comparison you can actually repeat

For your next price check, record the selection and its rules beside each quote. Keep a timestamp and the stake the sportsbook will accept. A screenshot of an earlier offer can't establish the price available when you submit.

If a line changes, recalculate using the new price before deciding what to do. Avoid treating a price difference observed once as a permanent advantage for that operator. A claim about average pricing would need a defined set of matching markets observed at matching times.

Questions about comparing these sportsbooks

Which sportsbook has better odds?

Choose by the current price for the exact wager. The hypothetical examples here establish no overall winner between bet365 and BetMGM.

Can opposite fourth-quarter bets both lose?

Yes. If one includes overtime and the other excludes it, their scoring periods differ. Check the rules attached to both markets before treating them as opposite outcomes.

Make your next bet365 vs BetMGM comparison with the period written beside the price. Read that line before you read the potential payout.
