Millionaire Fan Tan
Game Mechanics & Rules
Millionaire Fan Tan is a provably fair implementation of the ancient Chinese counting game. A random count of beads is generated and divided by four; players bet on the remainder (1, 2, 3, or 4). Additional bet variants - Nim, Kwok, and Nga Tan - cover multiple remainders at adjusted payouts. The Golden Bead triggers at a fixed probability per round.
- Select a primary bet: Fan (single remainder 1, 2, 3, or 4). This bet pays 3:1 if the bead count remainder matches your selection.
- Optionally place variant bets: Kwok (two adjacent remainders, pays 1:1), Nga Tan (two non-adjacent remainders, pays 1:1), or Nim (one remainder wins 2:1, one push, one loss - a split-payout structure). Nim provides a hybrid single/split coverage at reduced variance.
- The SHA-256 chain generates a random integer representing the total bead count. The count modulo 4 determines the winning remainder (with count divisible by 4 mapping to remainder 4).
- All bets covering the winning remainder are paid at their published ratio. Bets on non-winning remainders are lost.
- The Golden Bead evaluates independently per round. When triggered, jackpot eligibility conditions are assessed.
Bets and Payouts
Fan Tan resolves one of four results (1, 2, 3, or 4) from a provably fair SHA-256 hash per round. Bet types cover single numbers, corners, edges, odd/even, and nim (range) bets. Min bet $0.10, max $100.
Core bets
| Bet | Payout | Details |
|---|---|---|
| Number (1-4) | 3:1 | Pick the exact outcome. 25% win probability. |
| Corner | 1:1 | Two adjacent numbers. |
| Edge (Nim) | 1:1 + push | Pick two numbers. Wins on one, pushes on the other. |
| Odd / Even | 1:1 | Outcome 1/3 (odd) or 2/4 (even). |
Millionaire Mode

Optimal Strategy & Analysis
The four remainder values (1, 2, 3, 4) have equal probability of 25% each assuming a uniformly random bead count, making number selection strategically neutral.
For EV-focused play, pure Fan bets or Kwok/Nga Tan bets dominate Nim in expected return per unit risked.
Coverage strategies combining Fan and Kwok bets can reduce variance at a given total stake: betting two remainders via Kwok at 1:1 alongside one Fan bet creates overlapping coverage. However, this does not reduce the composite house edge - each bet maintains its own edge independently. Multi-bet coverage trades variance for no improvement in expected return.
While Millionaire Mode is active, standard wins pay at 90% of the off-mode rate; that 10% margin is what funds the jackpot shot on every round. How Millionaire Mode's jackpot trigger works for Fan Tan is shown in the in-game Millionaire Mode panel.
Provably Fair Verification
Fan Tan generates a random integer representing the bead count using the SHA-256 chain from server seed, client seed, and nonce. The integer is taken modulo 4, with a modulo-0 result mapped to remainder 4, producing equally probable outcomes in [1, 2, 3, 4]. This modular mapping is published and verifiable, allowing players to reconstruct any round's result from the revealed seeds.
The server seed is committed as its SHA-256 hash before the session. Post-session seed revelation enables reconstruction of every round result. The Golden Bead uses a separate nonce suffix for its proof chain, maintaining independence from the bead count derivation. All fairness parameters are accessible in the in-game panel and exportable for third-party verification.
Millionaire Mode Technical Details
Millionaire Mode in Fan Tan is free to enable; there is no separate per-round fee. Each round can trigger a Golden Bead; the in-game Millionaire Mode panel shows exactly how the trigger works for Fan Tan.
While Millionaire Mode is active, standard wins pay at 90% of the off-mode rate. That 10% margin is what funds the jackpot shot on every round; the main-game mechanics are unchanged.
A Golden Bead opens the jackpot condition. The jackpot is a fixed $1,000,000, pre-funded and paid as a single transaction when the condition resolves.
The jackpot does not accumulate between rounds. Every Golden Bead is a full attempt at the headline figure.
Frequently Asked Questions
What is Millionaire Fan Tan and how does it work?
Millionaire Fan Tan is a provably fair implementation of the ancient Chinese bead-counting game. A random integer is generated and taken modulo 4 to produce a remainder (1-4). Kwok and Nga Tan variant bets cover two remainders at 1:1. The SHA-256 chain generates the bead count from server seed, client seed, and nonce. How Millionaire Mode's jackpot trigger works for Fan Tan is shown in the in-game Millionaire Mode panel.
How does Millionaire Mode function in Millionaire Fan Tan?
Millionaire Mode is free to enable with no per-round fee. While it is on, standard wins pay at 90% of the off-mode rate; that 10% margin funds the jackpot shot on every round. Each round can trigger a Golden Bead (the in-game Millionaire Mode panel shows how the trigger works for this game); the $1,000,000 jackpot is pre-funded and paid in full when the condition resolves.
How can I verify Millionaire Fan Tan is provably fair?
The fairness panel provides the committed server seed hash, client seed, and nonce. The bead count is derived by applying SHA-256 to the concatenated seeds and nonce, then taking the result modulo 4 (with 0 mapped to 4). Post-session seed revelation allows reconstruction of every round. The Golden Bead uses a separate nonce suffix for its independent proof chain.
Which cryptocurrencies are accepted for Millionaire Fan Tan?
BTC, ETH, LTC, USDT (ERC-20/TRC-20) and BNB are all supported. Deposits credit your account in USD; every stake, payout and jackpot in Millionaire Fan Tan is denominated in USD regardless of which crypto you sent. Withdrawals return on-chain to a wallet address you nominate at cash-out time, subject to standard network confirmation.
What is the mathematically optimal strategy for Millionaire Fan Tan?
All four Fan Tan remainders carry equal probability; number selection is strategically irrelevant. Kwok and Nga Tan offer variance reduction at the same edge as Fan bets. How Millionaire Mode's jackpot trigger works for Fan Tan is shown in the in-game Millionaire Mode panel.
