Crypto Dice
Crypto dice on Llamabet is the most transparent game in the casino: pick any win chance from 1% to 95%, and the payout is always exactly 99 divided by that chance — a flat 1% house edge at every single setting. Every roll is committed to the Sui blockchain before you bet and verifiable after, from a 1 SUI minimum.
Roll the dice →One slider, one formula, zero fine print
Dice strips gambling down to its skeleton. You choose Roll Under or Roll Over and slide a target to set your win chance anywhere from 1% to 95%. The game then rolls a number; land on the right side of your target and you win. The payout multiplier is not a menu of mystery odds — it is a single published formula: 99 divided by your win chance. That is the entire game. There are no side bets, no bonus rounds, no paytable with an asterisk. Because the formula is fixed and public, you can compute your exact expected value before you ever click roll, at any setting, in your head. No other casino game hands you its complete mathematics in one line.
Worked examples: 10%, 49.5%, 90%
Run the formula at three settings and you will understand the whole game. At a 10% win chance, the multiplier is 99 divided by 10, or 9.9x — you win one roll in ten, and a 1 SUI bet returns 9.9 SUI when it hits. At 49.5%, the near-coin-flip setting, the multiplier is exactly 2x: win about half your rolls and double your stake each time. At a 90% win chance, the multiplier is 1.1x — you win nine rolls in ten, grinding out 0.1 SUI profit per winning 1 SUI bet. Now check the expected value of each: 0.10 x 9.9 = 0.99, 0.495 x 2 = 0.99, 0.90 x 1.1 = 0.99. Every setting returns 99% of stake in expectation. The slider changes the shape of your session, never the price of it. Compare that with table games where every bet type has its own odds and its own trap doors: in dice there is exactly one price, and you just proved it three different ways.
A flat 1% edge — the honest benchmark
That constant 0.99 is the point: Llamabet dice carries a 1% house edge — a 99% RTP — at every setting, and the formula proves it rather than a certificate claiming it. For context, the Wizard of Odds' comparison of casino games puts double-zero roulette at 5.26%, many slot machines at 5-15%, and blackjack at roughly 0.5% only if you play perfect basic strategy. Dice gives you near-blackjack pricing with zero strategy required and zero ways to misplay. There is no decision you can get wrong, no chart to memorise, no skill gap between you and the sharpest player in the room. You are paying a fixed, published 1% for entertainment and variance, and you can audit that price yourself. If house edge is the cost of playing, dice is the only game with the price printed on the front.
Committed before the roll, revealed after
Transparency in the payout formula would mean little if the roll itself were rigged, so the roll is provable too. Before betting, Llamabet generates a server seed and publishes its hash to the Sui blockchain — an immutable commitment made while your bet is still hypothetical. The roll result is then derived deterministically from that committed server seed plus your own client seed, which the house does not control. After the round the server seed is revealed: hash it, compare against the on-chain commitment, and recompute the roll with the published algorithm. If everything matches — and you can check in seconds — the house provably could not have chosen the outcome after seeing your bet. The 1% edge you calculated is the 1% edge you actually paid.
The best first crypto game
If you have never placed an on-chain bet, start here. Dice has the gentlest learning curve in the casino — one slider, one button — and the tightest feedback loop for understanding what provable fairness actually means, because a single roll is trivial to verify end to end. The minimum bet is 1 SUI, so a small stack buys a long education. Onboarding is equally light: sign in with Google and zkLogin derives a self-custodial Sui wallet with no seed phrase and nothing to install, or connect a Sui wallet like Slush. Wins settle to your own wallet in about a second. And if you want zero stakes while you learn, a free play-money practice mode at /dice/practice runs the full game without a wallet at all. Learn the commit-reveal cycle on dice, and every other provably-fair game makes sense instantly.
Pick your variance, respect it
The slider is really a variance dial, and knowing what each zone feels like is the closest thing dice has to strategy. High win chances (80-95%) produce long streaks of tiny wins punctuated by rare, painful losses — smooth until it suddenly is not, and a run of losses at 1.1x takes many wins to repair. The middle (around 49.5%) is the classic coin-flip grind: balanced swings, easy to reason about, the setting most players should start at. Low win chances (1-15%) are lottery mode: your balance bleeds through dry spells, then a 9.9x or bigger hit lands. All three cost the same 1% in expectation, but they demand very different bankrolls to survive their swings. Set a session budget before you roll, size bets so a cold streak cannot end you, and never chase a loss by cranking the multiplier. The math is fixed; discipline is the variable.
Frequently asked questions

How do I verify a dice roll was fair?
