AFL Same Game Multi Tips: A Smarter Way to Build Them
Same game multis are the most popular - and most margin-heavy - AFL betting product. Here is how to structure AFL SGM legs that are not just a donation, and the free calculator to price them.
What is an AFL same game multi?
A same game multi (SGM) combines two or more markets from a single AFL match into one bet - for example Geelong to win + Jeremy Cameron 2+ goals + over 165 total points. All legs must win to collect. Because the legs come from the same game they influence each other, so the bookmaker applies a correlation discount rather than simply multiplying the odds. Our free SGM calculator prices any multi you build and shows how big that discount is.
The data-driven rules for AFL SGMs
1. Anchor on the highest-probability leg. Usually the match result or the line. Our model's win probability for every game is in this week's tips - start from the games where it is most confident.
2. Keep it to 2-3 legs. Every leg compounds both the variance and the margin. A 5-leg AFL SGM is almost always negative value, however tempting the payout.
3. Prefer correlated legs. A winning team plus their key forward to kick 2+, or a favourite plus the over in a game you expect to be high-scoring. Correlated outcomes are where SGM value hides, because the true joint probability is higher than the discounted price implies.
4. Avoid the lottery legs. First goal scorer and exact-disposal props are high-variance margin traps. AFL margins are volatile - 30% of games are blowouts, 17% are decided by a goal - so margin-band legs are harder than they look.
AFL SGM vs multi across games
A same game multi combines legs within one match (with correlation pricing). A standard multi combines results across different matches (straight odds multiplication). They are different products - use the multi calculator for cross-game multis and the SGM calculator for single-game ones.

FAQ
What is a good AFL same game multi?
A 2-3 leg multi anchored on a high-probability result, with correlated add-ons (winning team + their forward to score, or a favourite + the over in a game you expect to be open). Price it in the calculator before betting.
Why is my AFL SGM price lower than the legs multiplied?
Correlation. When legs tend to happen together, the bookmaker discounts the combination because the true joint probability is higher than independent multiplication implies.
How many legs should an AFL SGM have?
Two or three. More than that compounds the margin faster than the payout justifies - most long SGMs are entertainment bets, so size the stake accordingly.
