Crypto Dice is the game that started the whole provably-fair world: you set a target number, bet whether the roll lands over or under it, and your chosen win chance sets the payout, the slimmer the chance, the bigger the multiplier. It runs a 99% RTP, one of the lowest house edges anywhere, and every roll is provably fair. There’s no skill, just a slider and the odds you pick. One honest note: ChipReign does not recommend crypto casinos to readers in the US, UK or Australia. Here’s how Dice works and how to play it sensibly.

What Crypto Dice is

Forget the dice you throw at a craps table. Crypto Dice is a screen game: a slider runs from 0 to 100, you set a target somewhere along it, and you bet whether the random number that rolls will land above or below your mark. That’s it. The game generates a number, and if it falls on your side of the line, you win. No props, no croupier, no decisions once you’ve set your bet. Just you, a number line, and the odds you chose.

It matters because Dice is where this whole corner of gambling began. The first provably-fair crypto game, SatoshiDice, launched back in 2012 and proved you could let players verify a result with cryptography instead of trusting the house. Every Crash, Plinko and Mines game that came after is built on that idea. Dice is the granddad of the lot, and it still runs a 99% RTP, which is about as fair as a casino game gets.

How to play Dice

Set your bet. Pick a stake.
Choose over or under. Decide whether you’re betting the roll lands above or below your target.
Drag the slider. This sets your target number, and with it your win chance, shown as a percentage right there on screen.
Roll. The game generates a number. Land on your side and you win your stake times the multiplier; miss and you lose the bet.
Or auto-bet. Set it to roll automatically at your chosen odds, which is how most regulars play.

The chance-and-multiplier trade

This is the entire game, so it’s worth a moment. When you move that slider, you’re trading win chance against payout. Set a target that gives you a 90% chance to win, and the multiplier is tiny, barely above your stake back, because you will win nearly every roll. Set one with a 2% chance and the multiplier is huge, but you’ll lose far more often than you hit. The 99% RTP holds steady across the whole slider; you’re only choosing the shape of the ride.

So a high win chance is the grinder’s setting, lots of small wins, gentle on the balance. A low win chance is the gambler’s setting, rare big hits and long cold runs between them. Neither beats the house, because the edge is baked in at every point on the line. The slider just lets you pick your poison: slow and steady, or swing for the fences.

🎲 Chip’s Vegas

I’ll tell you what gets me. Dice used to mean a craps table, two actual cubes flying off the back wall, a stickman, a crowd six deep yelling for a seven, the loudest spot on the floor. Best energy in the building. Now a fella tells me dice is a slider on his phone he taps in silence on the bus. Same word, and not one thing in common with what I knew. The maths is cleaner, I’ll give it that, you can even check it yourself. But I do miss the noise, pal.

How to play Dice well

There’s no strategy that beats Dice, because each roll is random and provably fair, with no memory of the last one. What you can manage is your settings and your money. Pick a win chance that suits your bankroll, use auto-bet with a hard stop-loss so a cold streak can’t run away from you, and treat that 99% RTP for what it is: excellent value, but still a slim edge to the house over time. You won’t grind it into a profit.

The trap to avoid is the low-chance, high-multiplier end of the slider with a betting system layered on top, doubling after losses to “catch” the big one. That’s how balances vanish in a hurry. Set a budget first, keep your stakes flat, and enjoy Dice as the clean, fast game it is. It lives at the crypto operators in our best crash game casinos guide, with the same caveat we always give: we don’t recommend crypto casinos to US, UK or Australian readers.

🔒 Try it yourself: verify a result

What this does: takes the revealed server seed, your client seed and the nonce for a specific bet, then independently computes the outcome Stake should have shown you. If they match, the result is provably fair. All computation happens in your browser; nothing is sent to ChipReign.

Game

Revealed server seed

The server seed is only revealed after you change or rotate your seed pair on Stake. The unrevealed one is a hashed commitment.

Client seed

Nonce (bet number on this seed pair)

How Stake's provably fair system actually works

Stake generates every outcome using HMAC-SHA256 with the following inputs:

Server seed: generated by Stake; you see a hashed commitment before play; the unhashed value is revealed after you rotate seeds.
Client seed: chosen by you (can be your username or any string).
Nonce: an integer that increments with every bet on the same server/client seed pair.

The HMAC output (32 bytes) is then converted to a game outcome using game-specific rules:

Dice, Limbo, Crash: the first 4 bytes become a float between 0 and 1, then a game-specific formula derives the result.
Plinko: each row uses 4 bytes to decide direction; position at the bottom determines the multiplier.
Mines: all 25 tiles are shuffled using a Fisher-Yates algorithm seeded by the HMAC bytes.

The system is fair because you can verify every outcome: the server couldn't have chosen a different number at the time, because the hashed commitment was published before your bet.

Frequently asked questions

How does Crypto Dice work?

You set a target on a 0-to-100 slider and bet whether a random roll lands over or under it. Your chosen win chance sets the payout: a high chance pays small, a low chance pays big. Win and you get your stake times the multiplier. It runs a 99% RTP and every roll is provably fair.

Is there a Dice strategy that wins?

No. Each roll is independent and provably fair, so no pattern or betting system beats the built-in edge. The only real choices are your win chance and your bankroll discipline. High chance stretches your money; low chance chases big multipliers. Both share the same 99% long-run return.

What is the RTP of Crypto Dice?

Dice runs up to 99% RTP at the top crypto casinos, among the lowest house edges of any casino game. The return stays the same wherever you set the slider, so changing your win chance alters the volatility, not the long-run edge. A high RTP is better value, not a guaranteed win.

Is Crypto Dice fair?

At a provably fair operator, yes, and you can verify it. The result of each roll is generated from seeds you can check after the fact, so neither the casino nor anyone else can rig it once you have bet. Dice was the first game to offer this, which is why it kicked off the whole provably-fair movement.
