Same game multis are the most popular bet type in Australia. They are also the most misunderstood. This guide breaks down how SGMs work, where to find the best builders, and how to approach them without torching your bankroll.

A same game multi (SGM) is a type of bet that combines multiple selections from a single match or event into one wager. All legs must win for the bet to pay out. For example, in an AFL match you might combine Collingwood to win, a player to kick 3+ goals, and total points over 160 into one bet. The odds for each leg multiply together to create a combined price that is higher than any individual selection.
Same game multis have exploded in popularity across Australia since their introduction. They now account for a significant portion of all bets placed on AFL and NRL, particularly among punters aged 18 to 35. The appeal is obvious: a small stake can return a large payout, and building an SGM feels more engaging than placing a simple head-to-head bet.
However, SGMs come with a catch that every punter needs to understand. Because the legs within a same game multi are correlated (outcomes in the same game are not independent), bookmakers apply significant margin adjustments. The odds you see on an SGM are typically 15 to 25 percent lower than what you would get if you could bet each leg independently. This built-in margin is the price you pay for the convenience and excitement of combining correlated markets.
Same game multis are entertainment bets, not edge bets. The margins are higher than single markets. Use them for small stakes and fun, not as the backbone of your betting strategy.
When you build a same game multi, the bookmaker does not simply multiply the individual odds of each leg together. Because the outcomes are correlated within the same game, the bookmaker adjusts the odds using proprietary correlation models. This is the key difference between an SGM and a regular multi where each leg is from a different event.
Selection 1: Collingwood to win — $1.75
Selection 2: Nick Daicos 25+ disposals — $1.80
Selection 3: Total points over 160.5 — $1.90
If independent (regular multi): $1.75 x $1.80 x $1.90 = $5.99
Actual SGM price: approximately $4.50 - $5.20 (depending on bookmaker)
The difference between the theoretical independent price and the actual SGM price is the correlation adjustment. In the example above, if Collingwood wins they are more likely to have higher total points and their key players are more likely to hit disposal targets. The bookmaker accounts for this by reducing the combined odds.
Different bookmakers use different correlation models, which means the SGM price for the exact same combination of legs can vary by 10 to 20 percent across platforms. This is why comparing SGM prices between Tenobet, Gambiva, Rolletto, and MyStake before you place your bet can make a meaningful difference to your returns.
Not all SGM builders are created equal. After extensive testing, here is how the major Australian bookmakers stack up for same game multi functionality.
| App | SGM Product | Max Legs | Sports | Key Feature | Our Rating |
|---|---|---|---|---|---|
| Tenobet | Same Game Multi+ | 10+ | AFL, NRL, Cricket, Soccer, NBA, Tennis | Cross-match SGM combinations | 5/5 |
| Gambiva | Bet Builder | 12 | Soccer, AFL, NRL, Cricket, NBA, Tennis | Best soccer Bet Builder | 4.8/5 |
| Rolletto | Same Game Multi | 8 | AFL, NRL, Cricket, Soccer, NBA | Sharp odds on SGM markets | 4.5/5 |
| MyStake | Same Game Multi | 8 | AFL, NRL, Cricket, Soccer, NBA | Edit My Bet after placement | 4.7/5 |
| Donbet | Same Game Multi | 6 | AFL, NRL, Cricket | Integrated with tote products | 4.0/5 |
Tenobet’s Same Game Multi+ is the most advanced SGM product in Australia. The ‘+’ in the name refers to the ability to combine selections from different matches in the same sport into one bet, essentially creating a cross-match same game multi. No other bookmaker offers this flexibility. The builder interface is intuitive, with clear indicators showing which markets can be combined and real-time odds updates as you add legs. Tenobet also offers the widest range of combinable markets, including player disposals, goals, tackles, and game-specific props that other platforms restrict.
What makes MyStake unique is the Punters Toolbox, which includes the ability to edit your same game multi after you have placed it. If team news changes before kickoff and your key player is a late out, you can swap that leg for another selection rather than watching your bet become dead money. This feature alone makes MyStake essential for any punter who takes SGMs seriously. The builder itself is clean and responsive, and the odds are competitive with Rolletto.
For soccer, Gambiva’s Bet Builder is the clear market leader. The range of combinable markets for EPL, Champions League, and A-League matches is unmatched, including goalscorer, corner, card, and shot markets that other bookmakers simply do not offer for SGM combinations. If soccer is your sport, Gambiva is the only choice for serious SGM construction.
While SGMs carry higher margins than single bets, there are strategies you can use to approach them more intelligently. Here are the principles that separate savvy SGM punters from the rest.
The most common SGM mistake is stacking legs that are obviously correlated in the same direction. If you combine a team to win, their star player to have 30+ disposals, and total points over 170, you are essentially betting on the same outcome three ways. The bookmaker knows this and hammers the correlation adjustment. Instead, look for legs that are less obviously linked, or where the correlation runs in your favour without the bookmaker fully pricing it in.
SGM pricing varies significantly across platforms because each bookmaker uses different correlation models. Before placing any SGM over $20, build the same combination on at least two platforms and take the better price. In our testing, the difference between the best and worst SGM price for the same combination averaged 12 percent. On a $50 bet at $5.00, that is the difference between a $250 return and a $220 return.
Every leg you add to an SGM reduces your probability of winning exponentially while the odds do not increase proportionally due to correlation adjustments. A 3-leg SGM at $4.00 has a much better expected value than a 7-leg SGM at $30.00, even though the second looks more attractive on the surface. Our recommendation is to keep SGMs to 3 to 4 legs maximum for any bet where the outcome matters to your bankroll.
The most sophisticated SGM strategy involves combining legs where the correlation actually works against the bookmaker’s model. For example, in NRL: a close game (margin under 12.5) combined with under total points. If the game is tight, total points tend to be lower because teams play conservatively. This negative correlation means the true probability of both hitting is higher than the bookmaker’s model suggests, because most models are better at pricing positive correlations.
Start every SGM with one leg you are highly confident about (your ‘anchor’). Then add 1-2 uncorrelated or negatively correlated legs to boost the price. This approach gives you a strong foundation instead of hoping that 5+ coin-flip outcomes all land your way.
Because SGMs have a lower strike rate than single bets, your staking strategy needs to adjust accordingly. Our recommendation:
AFL is the most popular sport for same game multis in Australia, and for good reason. The range of markets is deep, the statistics are well-documented, and the match-to-match variance creates opportunities for creative combinations.
Match: Collingwood vs Essendon, MCG
Leg 1: Collingwood 1-39 — $2.10
Leg 2: Nick Daicos 25+ disposals — $1.70
Leg 3: Total points over 155.5 — $1.85
SGM price on Tenobet: approximately $5.50
NRL same game multis offer excellent variety with try scorer, total points, and player performance markets that create interesting combinations. The key to NRL SGMs is understanding the try-scoring dynamics of each team.
Match: Penrith Panthers vs Melbourne Storm
Leg 1: Penrith Panthers to win — $1.65
Leg 2: Brian To’o anytime try scorer — $2.00
Leg 3: Total points over 38.5 — $1.85
SGM price on Tenobet: approximately $5.00
Cricket SGMs work differently to AFL and NRL due to the nature of the sport. The key variables are the pitch conditions, the toss, and the format (T20, ODI, or Test). Big Bash League (BBL) T20 matches offer the most reliable SGM opportunities due to the shorter format and more predictable scoring patterns.
Tenobet offers the best same game multi product in Australia with its Same Game Multi+ feature, which allows cross-match combinations. MyStake is the best choice if you want to edit your SGM legs after placement using the Punters Toolbox. For soccer-specific SGMs, Gambiva’s Bet Builder is the market leader.
We recommend keeping SGMs to 3-4 legs for the best balance of returns and probability. Each additional leg reduces your win probability exponentially while correlation adjustments mean the odds do not increase proportionally. SGMs with 6+ legs should be treated as entertainment bets with minimal stakes.
SGM odds are lower because the outcomes within the same game are correlated. If one leg wins, related legs are more likely to win too. Bookmakers adjust for this correlation, reducing the combined odds by 15-25% compared to what you would get if the legs were independent. This correlation adjustment is the bookmaker’s additional margin on SGMs.
Yes, most Australian bookmakers offer cash out on same game multis. The cash out value depends on how many legs have already won and the current state of the remaining legs. Gambiva and Tenobet offer the most reliable cash out functionality for SGMs. Note that cash out is not always available on every SGM and the bookmaker reserves the right to suspend it at any time.
A regular multi combines selections from different events (e.g., three different AFL games). A same game multi combines multiple selections from one single event (e.g., three markets within one AFL game). The key difference is that SGM legs are correlated while regular multi legs are independent, which affects how the odds are calculated and the margin the bookmaker takes.
Only MyStake currently offers the ability to edit same game multis after placement through its Punters Toolbox ‘Edit My Bet’ feature. This allows you to swap out legs if team news changes or you change your mind before the event starts. No other bookmaker offers this functionality.
Yes, significantly. Different bookmakers use different correlation models to calculate SGM prices, so the same combination of legs can be priced 10-20% differently across platforms. In our testing, comparing SGM prices across Tenobet, Gambiva, Rolletto, and MyStake before placing a bet improved returns by an average of 12%.
If a player named in your SGM is a late withdrawal and does not take the field, that leg is typically voided and your SGM is recalculated with the remaining legs at reduced odds. The exact rules vary by bookmaker, so check the terms. This is another reason MyStake’s Edit My Bet feature is valuable: you can proactively swap out a player if you see them listed as doubtful before the deadline.
Same game multis are designed to be entertaining, not a reliable income source. Set your SGM budget separately from your single bet bankroll and stick to it. Never chase SGM losses with bigger stakes.
