Dice is the purest game on the floor. There's no board to read, no dealer to beat, no bonus round hiding behind a segment — just a single number, a target you set yourself, and a bet on which side of that target the roll lands. It's the game where you choose the odds: crank the target for a near-certain small win, or push it the other way for a rare, heavy multiplier. Everything about your risk is a slider you control.

Here's exactly how a round works, how the payout is calculated, and where the return actually comes from.

The roll

Every round, the engine produces a single number between 0.00 and 99.99 — ten thousand equally likely outcomes, two decimal places. That's the whole random event. Your job is to predict which side of your chosen target it will fall on.

The rules

Set a target anywhere from 2.00 to 98.00 using the slider or the number box.
Choose a direction: Roll Over (you win if the number lands above your target) or Roll Under (you win if it lands below).
Set your bet — stakes run from €0.20 up to €20.
Roll. The number is drawn, and if it lands on your side of the target, you're paid at the multiplier shown before you rolled.

That's it. The two dials that matter — target and direction — set your win chance, and your win chance sets your payout. They move in opposite directions on purpose.

Win chance and multiplier

The further you make the win easier, the less it pays — and vice versa. The relationship is exact math, not a mood the game is in.

Your win chance is simply how much of the 0–100 range sits on your winning side. Roll Under 50 wins on any number below 50, so that's about a 50% chance. Roll Under 90 wins on almost everything, so it's a ~90% chance. Roll Over 90 flips that — you only win on the top sliver, roughly a 10% chance.

The multiplier is then set from that chance with a fixed formula:

multiplier = 0.97 ÷ win-chance

The 0.97 is the return constant — it's what makes the whole game a verifiable, fixed 97% return with a 3% house edge baked in, no matter where you set the target. A few worked examples:

50% win chance → 0.97 ÷ 0.50 ≈ 1.94×. Win a €10 bet, collect €19.40.
25% win chance → 0.97 ÷ 0.25 ≈ 3.88×.
10% win chance → 0.97 ÷ 0.10 ≈ 9.70×.
90% win chance → 0.97 ÷ 0.90 ≈ 1.08× — small, frequent wins.
~2% win chance (target pushed to the extreme) → nearly 48×.

The screen always shows you the live win chance, the multiplier to four decimals, and the exact payout on win before you commit. Nothing is hidden.

Where the 97% comes from

Notice that the return constant is 0.97 at every setting. That's the point: the house edge is a flat 3%, and it does not change whether you play it safe at 98% or chase a 48× longshot. A safe target wins often but pays barely over your stake; a risky one pays big but rarely lands — multiply the chance by the payout in either case and you get the same 97% expected return. There is no "smart" target that beats the edge. You're not choosing a better bet; you're choosing how often you want to win versus how big.

This isn't a number you have to take on faith — it's the 0.97 ÷ chance formula the game computes openly, and every roll is verifiable after the fact (below).

Is there a strategy?

Not in the sense of beating the edge — there isn't one, and any "system" that promises otherwise is selling the gap between how it feels and how it works. What you do control is variance. Low targets on Roll Under (or high targets on Roll Over) give you frequent small wins and a gentle ride. Extreme targets give you long dry spells punctuated by the occasional big hit. Chasing losses by doubling after every miss (the old Martingale) doesn't change your edge — it just front-loads the risk of a fast, brutal drawdown into a single cold streak. Each roll is independent and seeded fresh; the number is never "due."

Provably fair — verify the roll

Every Dice result is drawn from a committed seed, so you never have to trust that the number was honest:

Before you roll, the server publishes a SHA-256 hash of its secret server seed — the commitment.
Each roll is derived deterministically from serverSeed : clientSeed : nonce, where the nonce ticks up one per roll so no two are alike.
When you rotate the seed, the original server seed is revealed. You hash it, confirm it matches the commitment published beforehand, then recompute every number from your session and check each one against what you were paid.

Because the commitment is locked in before any roll, the server can't pick a number that hurts you and then invent a seed to justify it. The math only works one way. More on the scheme in our provably-fair cash-out games guide.

In one paragraph

6proclub Dice rolls a single number from 0.00 to 99.99. You set a target between 2 and 98 and bet whether the roll lands over or under it. Your win chance is just how much of the range sits on your side, and the multiplier is fixed at 0.97 ÷ that chance — a flat 3% house edge at every setting. Safe targets pay little and win often; extreme targets pay up to ~48× and rarely land, but the long-run return is the same 97% either way. Every roll is committed to a seed you can verify afterward, so the number is provably honest.
