Fan Tan is a classic game of pure probability widely featured in Macau land-based halls and modern live dealer suites. Based on dividing a random pile of beads into groups of four, its mechanics are completely transparent. Understanding how House Edge and Return to Player (RTP) apply to each bet type is essential for maximizing playing time and optimizing risk.
What Are House Edge and RTP in Fan Tan?
Understanding House Edge
The House Edge is the built-in mathematical advantage that ensures the casino retains a fixed percentage of all total wagers over long-term play. In Fan Tan, every outcome (1, 2, 3, or 4) has an identical 25% probability of occurring. The house edge comes entirely from a standard 5% commission deducted from winning payouts rather than manipulated odds.
What RTP Means
Return to Player (RTP) represents the theoretical percentage of all money wagered that a game returns to players over millions of rounds:
A bet carrying a 98.75% RTP features a 1.25% House Edge, meaning that for every $100 wagered over an extended period, the statistical expected return is $98.75.

Random Bead Pile Divided by 4
│
┌──────────────┼──────────────┬──────────────┐
Remainder 1 Remainder 2 Remainder 3 Remainder 4
(25.0%) (25.0%) (25.0%) (25.0%)
Because the four possible remainders are strictly equal in probability, true odds for a single-number win are 3 to 1. Casinos generate their edge by applying a 5% commission on winning wagers, reducing payouts slightly below true mathematical odds.
House Edge by Bet Type
Different bet types cover varying numbers of outcomes, yielding distinct payout ratios, effective house edges, and RTP values:
Factors That Affect House Edge
- Commission Variations: While 5% is standard across live suites like Evolution, non-standard tables or older venues taking higher rake directly increase the house edge.
- Push Mechanics: Bets incorporating pushes (like Nim and Nga Tan) return stakes without penalty on neutral results, helping preserve capital over time.
How RTP Is Calculated in Fan Tan
RTP is calculated by summing the expected payout of all outcomes, factoring in win probabilities and the 5% house rake:
RTP vs House Edge
Average RTP for Popular Bets
- Top-Tier (98.75% RTP): Sheh-Sam-Hong (SSH) and select Tan options.

Best Fan Tan Bets by House Edge
Bet Value Spectrum
│
├── Low Risk / Lowest Edge (1.25%) ──► Sheh-Sam-Hong (SSH) (75% Win Chance)
├── Medium Risk / Mid Edge (2.50%) ──► Kwok, Big/Small, Odd/Even (50% Win Chance)
└── High Risk / Highest Edge (3.75%) ──► Single Fan Bet (25% Win Chance)
Low House Edge Bets
- Sheh-Sam-Hong (SSH): By covering 3 out of 4 remainders, SSH offers a 75% win rate and the lowest house edge in the game at 1.25% (98.75% RTP), making it ideal for low-volatility bankroll growth.
- Kwok & Even-Money Options: Kwok (covering 2 numbers), Big/Small, and Odd/Even provide a strong 97.50% RTP with balanced 50% hit rates.
High-Payout Bets
-
Single Fan Bet: Paying out 2.85:1 net, single-number bets offer the highest individual payout but carry the game’s highest house edge (3.75%) due to commission drag across a lower 25% win frequency.
Tips for Choosing Fan Tan Bets
Compare Odds Before Betting
- Focus on Total Coverage: High-coverage options like SSH minimize variance and yield the highest long-term return rate.
- Account for Rake: Always calculate net expected returns using post-commission payouts rather than nominal odds.
Manage Your Bankroll
- Size Bets by Volatility: Keep single Fan wagers at 1% or less of total capital due to the 25% hit rate.
- Utilize Push Wagers: Integrate Nim or Nga Tan bets to gain partial coverage while hedging against total loss on targeted numbers.
Fan Tan stands out among casino table games for its fixed mathematical mechanics and transparent probabilities. By prioritizing high-coverage wagers like Sheh-Sam-Hong (SSH) with its 98.75% RTP, players can significantly reduce the house margin and enjoy greater bankroll longevity.
