What Are Same Game Multis?
Same game multis (SGMs) let you combine multiple betting selections from a single AFL game into one bet. Each leg must win for the SGM to pay out — but the combined odds make for potentially massive returns from small stakes.
SGMs are the fastest-growing bet type in Australian sports betting. They've exploded in popularity because they let punters "build a story" around each game — combining their view on the match result, the margin, individual player performances, and total points into a single wager.
But here's the reality: SGMs are also the bet type with the highest bookmaker margin. The correlation adjustments and margin stacking across multiple legs mean bookmakers typically hold 15–25% on SGMs, compared to 4–6% on single H2H bets. That doesn't mean they're unbeatable — but it means you need a disciplined approach to building them.
In the 2026 AFL season, SGMs are available across all major Australian bookmakers with an extensive range of player and team markets. Understanding which legs offer value — and which are margin traps — is the key to long-term SGM profitability.
Available SGM Legs
Modern AFL SGMs offer a wide range of markets to combine. Here are the most common leg types:
- Match result: H2H winner, margin bands (1-39, 40+), or draw.
- Player disposals: Over/under lines for individual players (e.g., 20+, 25+, 30+ disposals). Midfielders are the most popular selections.
- Player goals: Anytime goalscorer, 2+ goals, 3+ goals. Key forwards and mobile forwards are the go-to options.
- Total points: Combined game total over/under, or individual team totals.
- Margin betting: Specific margin bands like 1-9, 10-19, 20-29, 30-39, 40+.
- Quarter markets: First quarter winner, highest scoring quarter, half-time result.
- Player marks/tackles: Newer markets that are growing in popularity.
SGM Build:
Hawthorn 1-39 ($2.05) + Key Forward 2+ Goals ($1.50) + Star Midfielder 20+ Disposals ($1.22) = Combined $3.75
The logic: Hawthorn are at home where they're strong but Gold Coast are 3-0 to start 2026 — a close game is likely, making the 1-39 margin band a high-probability play. A consistent midfielder hitting 20+ disposals in 4 of their last 5 games is a near-certainty at $1.22 — this is the "banker" leg that adds value without adding significant risk. The forward has scored 2+ goals in 3 of 5 recent games and faces a defence that's conceded the second-most goals in the competition.
At $3.75, this SGM pays nearly 4-to-1 for a scenario that our model gives a roughly 30% probability. That's value.
The Correlation Trap
Correlation is the most misunderstood concept in SGM building — and the reason most SGMs lose money long-term. Here's how it works:
When two legs in your SGM are correlated, the outcome of one affects the probability of the other. The bookmaker adjusts the combined price to account for this — meaning you're paying a premium for selecting legs that naturally go together.
Common correlation traps to avoid:
- Team to win + team player goals: If your team wins, their forwards are more likely to have kicked multiple goals. The bookmaker knows this and adjusts accordingly.
- Over total + team to win by 40+: A blowout almost always produces a high total. These legs are heavily correlated.
- Multiple players from the same position: If one midfielder has a big game, it often means possession-heavy conditions that benefit all midfielders. Selecting two midfielders from the same team with 25+ disposals is a correlated play.
Independent legs to target:
- Midfielder disposals + match margin: A quality midfielder's disposal count is relatively consistent regardless of whether their team wins by 5 or loses by 20.
- Players from opposing teams: Combining selections from both sides reduces correlation compared to stacking one team.
- Defensive player stats + scoring totals: A defender's marks or disposals are largely independent of the overall scoring pattern.
Finding Value Legs
Not all SGM legs are created equal. Here's where the value typically hides:
- Midfielder disposals (20+ or 25+ lines): Elite midfielders are the most consistent performers in AFL. A player averaging 28 disposals over their last 5 games is an extremely safe 20+ selection. The $1.15–$1.25 price reflects this, but when combined with other legs, these "banker" legs build a solid foundation.
- 2+ goals for consistent forwards: Key forwards who average 2.5+ goals per game over their recent form are underpriced at the $1.40–$1.60 range for 2+ goals. Track the last 5 games specifically.
- Margin bands: The 1-39 band (a comfortable but not dominant win) is the most common outcome in AFL, occurring in roughly 55% of games. At odds of $1.80–$2.20, this is often the best-value result leg.
Common SGM Mistakes
- Too many legs: Every additional leg multiplies the bookmaker's margin. A 3-leg SGM has a manageable margin; a 10-leg SGM is paying 20%+ to the bookmaker before the game even starts. Stick to 3–5 legs for the best risk-adjusted returns.
- Chasing big odds: A $50 SGM looks exciting, but the probability of landing is typically 1–2%. Over time, you'll lose money faster than any other bet type. Focus on realistic SGMs in the $3–$8 range.
- Using season averages for player props: A player averaging 22 disposals for the season might be averaging 28 over their last 3. Recent form is far more predictive than season-long averages. Always check the last 5 games.
- Ignoring opponent quality: A forward who kicked 4 goals against the worst defence in the comp is a very different proposition against the best defence. Adjust your player targets based on the specific opponent.
- Stacking all legs on one team: If your team has a bad day, every leg fails simultaneously. Spread your risk across both teams in the match.
SGMs are the most fun you can have betting on AFL — but they need to be treated with respect. Build with discipline, avoid correlation traps, and focus on 3–5 leg SGMs where you have a genuine view on each selection. See our Round 3 tips for this week's recommended SGM builds.
