Millionaire Chuck-a-Luck
Game Mechanics & Rules
Millionaire Chuck-a-Luck is a three-dice carnival game where players bet on a single number from 1 to 6. Payouts scale with how many of the three dice show the chosen number: 1:1 for one match, 2:1 for two matches, and 10:1 for all three. How Millionaire Mode's jackpot trigger works for Chuck-a-Luck is shown in the in-game Millionaire Mode panel.
- Select a number from 1 to 6 by clicking on it. This is the number you are betting will appear on one or more of the three dice.
- Place chips on one or several numbers and other betting areas, then confirm. Each bet settles separately.
- The three dice are rolled simultaneously, each from its own SHA-256 hash of the committed seeds, the nonce and the die number, so every face is exactly equally likely.
- Count how many of the three dice show your chosen number. Zero matches means the bet loses.
- Payouts: exactly one die matches - 1:1; exactly two dice match - 2:1; all three dice match - 10:1.
- The probability distribution is: zero matches 57.87%, one match 34.72%, two matches 6.94%, three matches 0.46%.
Bets and Payouts
Chuck-a-Luck has eleven bet types: single numbers, High/Low (11-17 / 4-10), Odd/Even, Field, Triple, Pair Plus, Sequential Run, All Even, All Odd, and the two sum ranges. Each of the three dice resolves from its own SHA-256 hash, so every face is exactly equally likely. Check the displayed limits; Millionaire Mode has a separate minimum.
Core bets
| Bet | Payout | Details |

| Pair Plus | 1:1 | At least two of the three dice show the same number. |
| Sequential Run | 7:1 | Three different numbers in a run, such as 3-4-5. |
| All Even | 6.5:1 | Every die shows an even number. |
| All Odd | 6.5:1 | Every die shows an odd number. |
| Sum Low | 4.5:1 | The three dice total 7 or less. |

Play Modes
Chuck-a-Luck supports Manual and Auto via quick-roll batches (1-5 keys for 5/10/25/50/100 rolls).
Manual
Place bets, press Roll. Dice resolve. Layout persists for next roll.
Auto
Quick-roll hotkeys (1-5) fire 5/10/25/50/100 rolls in sequence with the current bet layout. Full auto-bet panel with custom counts is also available. Both modes stop for Golden Rolls and require a manual restart.
Stop conditions:
- Roll count reached.
- You press Stop.
- Server error (insufficient balance, network).
Replay and Shared Replay
Your own replays
Each completed roll joins your history as it settles. Click any row for its details, or press Replay to watch the roll again with the original dice.
Shared replays
Every roll has a shareable link. Anyone with the URL can watch without logging in.
What gets reproduced
Replays play back the recorded roll exactly as it happened. Balances are not re-applied.
Optimal Strategy & Analysis
By symmetry of a fair die, each number has identical probability of appearing on any given die, making number selection strategically irrelevant. The expected return on a 1-unit bet is 0.9537 units regardless of which number is chosen.
The number bet pays on a tiered ladder: match your chosen number on one die for 1:1, on two dice for 2:1, and on all three for 10:1. Single matches land most often and keep wins ticking over, while the triple is the headline hit.
Variance is moderate - the game frequently pays 1:1 single matches, with the 10:1 triple as the occasional big hit. A set session budget keeps the fast roll pace comfortable.
Millionaire Mode applies a flat 10% trim to every payout: a single match returns 1.8x your stake instead of 2x, a double returns 2.7x instead of 3x, and a triple returns 9.9x instead of 11x. How Millionaire Mode's jackpot trigger works for Chuck-a-Luck is shown in the in-game Millionaire Mode panel.
Provably Fair Verification
Chuck-a-Luck gives each of its three dice its own hash: SHA-256(server_seed + ':' + client_seed + ':' + nonce + ':' + die_index), with die_index 0, 1 and 2. The first eight hex characters of each hash are read as a 32-bit integer; a value of 4,294,967,292 or above (the top four values, which would make low faces very slightly more likely) is rejected and the die is re-hashed with ':r1', ':r2' and so on appended, and the first value below that line is taken modulo 6 and offset to the range [1, 6]. Every face is therefore exactly equally likely. The nonce increments per roll, maintaining a complete sequential audit trail for the session. Rounds played before the September 2026 change used the earlier method (characters 0 to 3, 4 to 7 and 8 to 11 of one hash, modulo 6), and the fairness page still verifies them under it.
The committed server seed hash is displayed in the fairness panel from session start. Post-session seed revelation enables full roll-by-roll reconstruction. The Golden Roll is read from characters 16 to 23 of SHA-256(server_seed + ':' + client_seed + ':' + nonce), a hash the dice do not use - each die has its own - so the dice result and the jackpot determination stay independent of one another. All parameters are exportable from the fairness panel for third-party verification.
Millionaire Mode Technical Details
Millionaire Mode in Chuck-a-Luck is free to enable; there is no separate per-round fee. Each round can trigger a Golden Roll; the in-game Millionaire Mode panel introduces the bonus for Chuck-a-Luck.
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 Roll follows its own jackpot rules.
A Golden Roll 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 Roll is a full attempt at the headline figure.
Frequently Asked Questions
What is Millionaire Chuck-a-Luck and how does it work?
Millionaire Chuck-a-Luck is a provably fair three-dice carnival game where players bet on a single number (1-6) and receive payouts scaled to the number of dice showing that value: 1:1 for one match, 2:1 for two, 10:1 for three. The SHA-256 system generates three independent die values per roll each from its own hash, so every face is exactly equally likely.
How does Millionaire Mode function in Millionaire Chuck-a-Luck?
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 Roll (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 Chuck-a-Luck is provably fair?
The fairness panel provides the committed server seed hash, client seed, and nonce. Each of the three dice comes from its own hash, SHA-256(server_seed + ':' + client_seed + ':' + nonce + ':' + die_index): the first eight hex characters are read as an integer, the rare top values that would bias the result are rejected and re-hashed, and the rest is taken modulo 6 and offset to [1, 6]. Post-session, the server seed is revealed and all rolls are reconstructable by applying this derivation to the revealed seed, client seed, and sequential nonces.
Which cryptocurrencies are accepted for Millionaire Chuck-a-Luck?
Deposits are made in crypto, and the cashier lists the coins accepted. You play Millionaire Chuck-a-Luck in whichever of your balances you select, and every stake and payout is settled in that currency. 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 Chuck-a-Luck?
Chuck-a-Luck allows several numbers and other betting areas in one roll. Number selection does not change expected return due to die symmetry. Bankroll management is the practical tool: flat bet sizing and session budgets. How Millionaire Mode's jackpot trigger works for Chuck-a-Luck is shown in the in-game Millionaire Mode panel.
