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, Nga Tan, and Ssh - cover multiple remainders at adjusted payouts. How Millionaire Mode's jackpot trigger works for Fan Tan is shown in the in-game Millionaire Mode panel.
- Select a primary bet: Fan (single remainder 1, 2, 3, or 4). This bet pays 2.85:1 if the bead count remainder matches your selection.
- Optionally place variant bets: Kwok (two remainders, either wins at 0.95:1), Nga Tan (three remainders - two win at 0.475:1, the third pushes), or Nim (two remainders - one wins at 1.9:1, the other pushes, everything else loses). Odd/Even covers 1/3 or 2/4 at 0.95:1.
- The SHA-256 chain generates a random integer representing the total bead count. The first eight hex characters of the hash, read as an integer and taken modulo 4, determine the winning remainder (with count divisible by 4 mapping to remainder 4).
- Winning selections pay their listed return; designated push selections refund your stake; other outcomes lose.
- 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 win/push bets. Check the table for current limits; Millionaire Mode has a separate minimum total stake.

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.
The single Fan bet is the high-payout position at 2.85:1, while the coverage bets spread your stake across more of the board - Kwok and Odd/Even over two numbers, Nga Tan over three - for steadier, more frequent wins. Nga Tan and Ssh both offer approximately 98.75% standard-mode RTP.
Coverage strategies combining Fan and Kwok bets spread your stake: betting two numbers via Kwok at 0.95:1 alongside one Fan bet at 2.85:1 creates overlapping coverage, trading a bigger single hit for more frequent smaller ones.
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 first eight hex characters are read as an integer and 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 jackpot trigger is not a separate chain: it is read from a different part of the SAME committed hash - characters 16 to 23, where the bead count comes from the earlier characters - so both are fixed by the one commitment made before the round and neither can be steered afterwards. 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 introduces the bonus 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; a triggered Golden Bead follows its own jackpot rules.
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. The first eight hex characters of the round hash are read as an integer and taken modulo 4 to produce a remainder (1-4). The Fan bet on a single remainder pays 2.85:1; Kwok covers two numbers at 0.95:1, Nga Tan covers three (two win at 0.475:1, one pushes). 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. Apply SHA-256 to server_seed:client_seed:nonce. Read the first eight hex characters as an integer, calculate 20 + integer % 40 for the bead count, then take modulo 4, mapping 0 to 4. Post-session seed revelation allows reconstruction of every round. The Golden Bead trigger is read from characters 16 to 23 of that same hash rather than from a separate chain, so one commitment fixes the bead count and the trigger together.
Which cryptocurrencies are accepted for Millionaire Fan Tan?

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, so which number you pick does not change your expected return.
