Key takeaways
- Baccarat Banker (8 decks, 5% commission) has the lowest house edge in this list at 1.06%. If you want the longest play for the least expected loss per unit wagered, this is the best standard table bet here.
- European roulette sits at 2.70%; American roulette is much worse at 5.26%. The extra 00 in American roulette roughly doubles the structural cost on a lot of bets compared with European.
- Common low-edge bets include baccarat banker/player and big/small in Sic Bo (Sic Bo Big/Small: 2.78%).
- Slots vary by title; a slot with RTP 96% implies a house edge of 4.00%. That is an average long-run cost — volatility changes how you experience it session to session.
- A typical two-way sports market at 1.91/1.91 has a verified margin of 4.50% — shop the lines across operators to reduce this cost where possible.
- Know the house edge, then size your bets to protect your bankroll. No system or progression beats the house edge; the only legal routes to a positive expectation are genuine advantage play or operator promotions that exceed the edge under their terms.
What 'house edge' means (from zero)
The house edge is the casino's long-run percentage advantage on a particular bet. If a game has a 2.70% house edge, the casino expects to keep 2.70 units for every 100 units wagered on that bet, over the long term. House edge is a mathematical expectation: it is the average outcome after many plays, not a prediction for an individual session or spin.
Two important clarifications:
- Short-term results are driven by variance (how widely outcomes swing) and luck. You can win or lose a lot over a short session even where the house edge is small.
- Different bets in the same game can have very different edges. The numbers in this guide are tied to specific, verified formats (for example baccarat results use 8 decks and a 5% banker commission where noted).
This guide lists verified house edges for common bets, explains the basic maths, gives worked examples using only the verified numbers, and offers practical bankroll advice based on those figures.
Games and verified house edges (straight list)
The following numbers come from the verified calculations used for this guide:
- Baccarat Banker (8 decks, 5% commission): 1.06%
- Baccarat Player (8 decks): 1.24%
- Baccarat Tie at 8:1 (8 decks): 14.36%
- European roulette (any standard bet): 2.70%
- American roulette (any standard bet except the 5-number bet): 5.26%
- Sic Bo Big/Small: 2.78%
- Dragon Tiger main bet (8 decks): 3.73%
- Typical two-way sports market at 1.91/1.91: 4.50%
- Slot with RTP 96%: 4.00%
How to read this list
Lower percentages mean a smaller average loss per unit wagered. Games with a smaller house edge give more expected playtime for the same cost; high edges (for example baccarat tie at 14.36%) will erode a bankroll much faster if you play them repeatedly. Always match the game's edge to your objective: if you want relaxed entertainment and the most play per dollar, prefer lower-edge bets. If you're chasing excitement or large occasional payouts, higher-edge or high-volatility products may suit you — but accept the higher long-run cost.
Maths: formula and a worked example
Core definitions and formulas you should know:
- House edge (HE) = Expected loss per unit wagered, expressed as a percentage.
- For a game with a stated RTP (return to player): HE = 100% − RTP.
- To convert house edge to expected loss for a given total wagered: Expected loss = HE × total wagered / 100.
Worked example using a verified number from this guide:
Slot with RTP 96%: RTP = 96%. Using HE = 100% − RTP, we get HE = 100% − 96% = 4.00%. That 4.00% is the verified house edge for a slot with 96% RTP.
Practical conversion: if you wager a given total on that slot over time, the long-run expected loss is 4.00% of whatever total you wager. House edge converts directly to a fraction of total stakes over the long run.
Second worked example using only the verified numbers: compare baccarat banker and player over a longer run. Suppose you wager a large total on each bet over many plays:
- Baccarat Banker: HE = 1.06%. Expected loss = 1.06% of that total wagered.
- Baccarat Player: HE = 1.24%. Expected loss = 1.24% of that total wagered.
That difference in expected cost is why even small percentage differences matter when you wager large totals over time.
Third worked example comparing European and American roulette for a typical short session: imagine a short session of repeated spins at 1 unit per spin:
- European roulette HE = 2.70%. Expected loss = 2.70% of the total wagered in that session.
- American roulette HE = 5.26%. Expected loss = 5.26% of the total wagered in that session.
On average, that session costs you more in American roulette than European for the same number of spins and bet size.

Why some games have such different edges
House edge is determined by the combination of true probabilities and the payouts the casino offers. Where the payout matches the true probability of an outcome, the house edge would be zero. In practice, casinos offer payouts that are slightly less than the fair probability value, producing a positive house edge.
Examples from the verified list:
- Roulette: the extra green 00 pocket in American roulette changes the denominator of the probability calculations and increases the edge from 2.70% (European) to 5.26% (American).
- Baccarat: special rules (who draws a third card and when) and the commission on banker wins result in slightly different edges between banker (1.06%) and player (1.24%), with a very high edge on the tie bet (14.36%), which pays 8:1 but is much rarer than that payout implies.
- Slots: advertised RTP (for example 96%) reflects the long-run percentage returned to players; HE = 100% − RTP, so a 96% RTP yields 4.00% HE.
Common mistakes from the table and sportsbook
- Chasing low short-term variance: players often switch from a low-edge game to a high-edge bet after a few losses; mathematically this increases long-run expected loss.
- Confusing volatility with house edge: a high-volatility bet can pay big sometimes while still having a low or high edge; volatility affects session swings but not the house edge itself.
- Assuming 'systems' beat the edge: betting progressions change variance but not expected loss. They can magnify losses and hit table limits sooner.
- Ignoring sportsbook margin: betting on lines without checking the bookmaker margin (for example, a market at 1.91/1.91 has a verified margin of 4.50%) reduces the value of your stake over time.
- Not checking game-specific rules: different casinos or tables may use different deck counts or commission rules — the values here are tied to the specified formats (for example, baccarat values assume 8 decks and a 5% banker commission where noted).
What this means for your bankroll
Use house edge to size bets and set session limits. Two simple rules:
- Only risk what you can afford to lose. House edge means expected loss; know your limit before you play.
- Lower-edge games give you more play for the same expected loss. For example, comparing expected loss per 100 units wagered: Baccarat Banker at 1.06% implies ~1.06 units loss per 100; a slot at 96% RTP implies 4.00 units.
Example bank-sizing method (conservative): set a session bankroll and cap any single bet at a small percentage of that bankroll. Practical ranges many experienced players use are between a small percentage and 2% of a session bankroll per bet depending on tolerance for swings. Smaller stakes give more spins or hands before variance becomes dominant. This is not a system to beat the edge — it is a money-management technique to control risk and avoid catastrophic drawdowns.
Remember: no betting pattern eliminates the edge. The only legal ways to overcome expected loss are legitimate advantage play (rare and often restricted) or promotions where the operator’s terms produce net positive expectation. Always read promotion terms carefully.
Using promotions (and where to look)
Promotions can shift the short-term maths in your favour (free spins, cashback, matched deposit bonuses). Whether a promotion is valuable depends on the offer and its wagering requirements. If the promotion removes enough of the operator’s margin under its conditions, it can create a positive short-term expectation. Check the promotions page and the specific terms for wagering, game weightings and withdrawal limits. MST88's promotions page and product-specific guides list current offers and their conditions.

FAQ
1. Which game has the lowest house edge?
From the verified numbers used here, Baccarat Banker (8 decks, 5% commission) has the lowest house edge at 1.06%. That makes it one of the most favourable standard bets in the casino for long-term expected loss.
2. Are all roulette bets the same edge?
Not exactly. This guide reports the standard average edge for European roulette as 2.70% and for American roulette as 5.26%. Different bets (single-number, column, even-money) have different hit frequencies and payouts, but the stated figures describe the overall structural advantage for standard bets in those wheel formats.
3. Do betting systems reduce house edge?
No. Betting systems (progressions, staking systems) do not change the house edge. They change the distribution of wins and losses and can increase the risk of large losses and hitting table limits sooner.
4. Can promotions beat the house edge?
Promotions can create short-term positive expectation if the promotion value exceeds the expected casino margin under the promotion’s terms. Always read wagering requirements and terms. Promotions are linked from the platform's promotions page: Promotions.
5. How should I use house edge numbers when I bet?
Use them to prioritise low-edge bets when you want more playtime for the same expected loss. Combine that knowledge with sensible stake sizing, session time limits and loss limits. House edge helps set realistic expectations, not guarantees.
6. Are sportsbook margins similar to casino edges?
Sportsbook margins are similar in concept but calculated differently. For a typical two-way market at 1.91/1.91, the verified margin is 4.50%. Shop around for better odds to reduce the margin you pay.
Common practical tips from experience
- If you enjoy live tables, favour the lowest-edge side bets (for baccarat, banker/player) and avoid high-edge specialty bets unless you accept the cost. For example, the baccarat tie at 14.36% is a high-cost bet if repeated often.
- On slots, check the game RTP and volatility. A 96% RTP implies 4.00% house edge but volatility will define how bumpy your session feels — big wins come rarely, and swings can be large.
- For sports bettors, compare implied margins across sportsbooks and markets — a 4.50% margin at 1.91/1.91 is typical but small differences in odds compound over many bets.
- Use account tools: set deposit and loss limits, and use time limits to reduce impulse increases in bet size. These controls protect both your bankroll and your decision-making.
- Track your play: simple records of stakes, session length and outcomes help you see how house-edge expectations compare with your real results and whether you need to adjust stakes or stop.
Conclusion
House edge is a compact, powerful measure: it tells you how much, on average, a bet costs over the long run. Use the verified numbers in this guide to compare options and size bets to protect your bankroll. Play games you enjoy, but play them with clear limits and realistic expectations.
Adults only. 18+ (Philippines 21+). Gambling is entertainment, not a way to earn money. Set money and time limits before you play; stop if you chase losses, borrow to play, or feel anxious. If you need help, pause play, use account limits or self-exclusion, and contact local support services.
