How to Play Crypto Dice: The Complete Beginner's Guide
Crypto dice is the simplest casino game ever built, and that simplicity is exactly why it became the flagship game of provably-fair gambling. There is no dealer, no pay table to memorize and no hidden rules: you choose your own win probability, the payout adjusts automatically, and the house edge is a flat 1% at every setting. This guide walks you through how the game works, the payout formula, worked examples, and what to expect from your first session on Llamabet.
Roll the dice →The game in one sentence
Every round of crypto dice generates a number between 0 and 100 (or 0 and 9,999 scaled down — the range is cosmetic). Before the roll, you pick a target and a direction: roll under 10, roll over 49.5, roll under 90 — whatever you like. If the number lands on your side of the target, you win. The distance between your target and the edge of the range is your win chance, and you set it yourself with a slider. That is the entire game. Unlike blackjack there are no decisions mid-round, and unlike roulette there is no board of overlapping bet types. One slider, one button, one number. Because you control the win probability directly, dice doubles as the clearest possible demonstration of how casino math works: you can watch the payout move in real time as you drag the slider, and the relationship between risk and reward is never hidden behind game rules.
The payout formula: 99 divided by win chance
On Llamabet the payout multiplier is always 99 divided by your win chance in percent. A fair game — one with zero house edge — would pay 100 divided by your win chance, so the missing 1 is the house edge: exactly 1%, at every setting, forever. Another way to say the same thing: the return to player (RTP) is 99% no matter where you put the slider. This is dramatically more transparent than most casino games. Slots hide their RTP in fine print and it commonly sits between 90% and 96%. American roulette takes 5.26% of every bet on average. Dice tells you the price of every roll up front, and the price never changes. Because the formula is public, you can verify it yourself before betting a single SUI: multiply the displayed payout by the win chance and you will get 0.99 every time, i.e. 99 cents of expected return per 1 SUI wagered.
Worked examples: 10%, 49.5% and 90%
Set the slider to a 10% win chance and the payout is 99 divided by 10, which equals 9.9x. Bet 1 SUI, win roughly one roll in ten, and each win returns 9.9 SUI. Set it to 49.5% — the classic near-coinflip setting — and the payout is 99 divided by 49.5, which equals exactly 2x. You win just under half the time and double your stake when you do. Set it to 90% and the payout is 99 divided by 90, which equals 1.1x: you win nine rolls in ten but each win only adds 10% to your stake. Run the expected-value math on any of these and you land in the same place. At 10%: 0.10 times 9.9 equals 0.99. At 49.5%: 0.495 times 2 equals 0.99. At 90%: 0.90 times 1.1 equals 0.99. Every configuration returns 99% of the wager on average. The slider changes the shape of your results, never the price.
Why dice is the most transparent casino game
Two things make dice uniquely honest. First, the math is fully visible: the edge is a single published number and the payout formula fits in one line. Second, the roll itself is provably fair on Llamabet. Before you bet, the house commits to a secret server seed by publishing its SHA-256 hash on the Sui blockchain — a public, immutable record created before your wager exists. Your roll is derived deterministically from that server seed combined with a client seed you can set yourself. After the round, the server seed is revealed, and you can recompute the hash and the roll to confirm nothing was manipulated. Because the commitment lives on-chain rather than on the operator's own website, the house cannot quietly swap seeds after seeing your bet. No traditional online casino offers this: you are trusting a certificate from an auditor you have never met. With on-chain dice, you are trusting arithmetic.
Your first session on Llamabet, step by step
Getting started takes about a minute. Sign in with Google — zkLogin derives a real Sui wallet from your Google account with no seed phrase and nothing to install — or connect an existing Sui wallet such as Slush. Fund it with SUI, open the dice game, and set a bet of at least 1 SUI, the table minimum. Drag the slider to your preferred win chance, check the payout it implies, and roll. Wins settle to your wallet on-chain in about a second; there is no withdrawal queue because there is no custodial balance to withdraw from. After any roll, open the fairness panel to see the server-seed hash that was committed before your bet and, once the seed rotates, verify the roll yourself. A sensible first session: pick 49.5%, bet the minimum, and roll twenty times just to feel the rhythm of a near-coinflip game before experimenting with the extremes of the slider.
Variance: what the slider really controls
Since the edge is fixed, the slider is purely a variance dial. At 90% win chance, your session is a slow grind: long strings of small wins punctuated by occasional losses that erase nine wins at once. At 10%, it is the mirror image: long droughts, then a 9.9x hit that can put you ahead for the whole session. Neither setting is better — over enough rolls both lose 1% of total wagered — but they feel completely different, and the drawdowns differ enormously. Low win chances can produce losing streaks of 30, 40 or more rolls with entirely ordinary probability, so they demand a much smaller bet relative to your bankroll. High win chances produce smoother charts but tempt players into oversized bets right before the inevitable loss lands. Decide your session budget before you start, size bets so a bad streak cannot end your session early, and treat every roll as entertainment with a known 1% price tag — never as income.
Frequently asked questions
What is the house edge on crypto dice?
On Llamabet it is a flat 1% at every win-chance setting, because the payout is always 99 divided by your win chance instead of a fair 100. Equivalently, the RTP is 99% on every roll — better than almost any slot and better than single-zero roulette's 97.3%.
How do I know a dice roll was not rigged?
The hash of the secret server seed is published on the Sui blockchain before you bet, and the roll is derived deterministically from that seed plus a client seed you control. After the seed is revealed, you can recompute both the hash and the roll and confirm they match. The house cannot change an outcome it committed to in advance.
What win chance should a beginner pick on dice?
The house edge is identical everywhere, so it is purely a variance choice. Around 49.5% gives a 2x payout and coinflip-like swings, which is the easiest way to learn the game. Very low win chances need a much bigger bankroll cushion because long losing streaks are normal, not unlucky.
