What Is Stake Primedice?
Quick answer
Stake Primedice, spelled Prime Dice on its game page, is an in-house Stake dice game. You pick where a roll from 0 to 100 must land: over a number, between two numbers, or in either of two ranges. Stake sets its RTP at 99%, a 1% house edge. The less you cover, the higher the Multiplier.
- Bet over a number or between two, or add a second range
- Every roll can be checked with your own seed
- !A second range raises the Win Chance and lowers the Multiplier

How to Play Primedice on Stake
- Open Primedice from the Stake Originals lobby. Manual mode plays one roll per bet.
- Enter your Bet Amount in the currency you hold. The ½ and 2× buttons halve or double it.
- Set where the roll must land. On Roll Between, move the slider to set both ends of your range, from 0 to 100.
- Stake’s page also mentions Roll Over: you win if the roll lands over the number you set.
- Want two ranges? Range Betting adds a second one with the sliders, for example 1 to 20 and 30 to 35. A roll in either range wins.
- Check the Multiplier, Win Chance and Profit on Win, then press Bet. To play a series of rolls, switch to Auto and set how many rounds it plays.
How Primedice Pays: Win Chance and Multiplier
Every Primedice win pays the same way: your bet times the Multiplier. The Multiplier follows your Win Chance, the share of the 0 to 100 scale your bet covers. With two ranges, the Win Chance counts both. Stake lists one RTP for the whole game, 99%, and no separate figure per bet type. Our table is calculated from that single figure: the Multiplier works out to 99 divided by the Win Chance, so covering half the scale pays 1.98x and a tenth pays 9.9x.
Over a long run of rolls, the 1% house edge means about $1 kept for every $100 wagered. From Bronze VIP ($10,000 wagered), or from sign-up with code BONUSTIIME once Stake support activates it, Stake’s rakeback returns 3.5% of that edge, about 3.5 cents per $100. How much of the scale you cover changes the swing, and the game shows the exact Multiplier before each roll.
Limbo and Crash, two other pick-a-target Originals, also run at 99% RTP. To compare every Original, see our house edge table.

Primedice Strategy: What You Can Control
You control
- Your bet size and how many rolls you play
- Your Win Chance: wide cover for frequent small wins, narrow cover for rare big ones
- A loss limit and a time limit, set before you start
You don’t control
- Where the roll lands: every result is random
- The house edge, built into every Multiplier
- Streaks: the last roll has no effect on the next
Doubling your bet after each loss (Martingale) does not change the edge. It makes losing runs more expensive, and it stops at Stake’s maximum bet and maximum profit per bet. Auto plays the number of rounds you set for you: it does not change the edge either.

How to Check a Primedice Roll
Primedice turns your seeds into one roll from 0 to 100. Your bet type and ranges do not change that roll, only whether it wins and what the win pays.
- Before you play, open the game’s fairness settings and note the hashed server seed.
- After your session, rotate your seed: Stake reveals the old server seed.
- Hash it, compare it with the one you noted, then replay any roll with your client seed and nonce.

Stake Primedice FAQ
Is Stake Primedice Rigged?
No. Your client seed, Stake's server seed and the nonce set the roll before you press Bet, whatever ranges you chose. Stake shows the server seed's hash first, so once it is revealed you can recompute any roll and check it against your ranges.
What Is the RTP of Stake Primedice?
Stake lists Primedice's RTP at 99%, which leaves a 1% house edge. Over many rolls that is about $1 kept per $100 wagered.
Is Stake Primedice the Original Primedice?
It is Stake's own version. Stake's page calls Prime Dice one of the original Bitcoin casino classics and says its version pays homage to the original site that featured the game. Its page presents Range Betting as an additional feature, so one bet can cover two ranges.
Does Range Betting Change Your Odds in Primedice?
Only through the Win Chance. A second range adds to the part of the scale you cover, so you win more often and the Multiplier drops. Stake lists one RTP for Primedice, 99%, with no separate figure for Range Betting.
What Is the Max Win on Stake Primedice?
Stake does not publish one figure. The Multiplier for your ranges is shown in game before you bet, and it rises as your Win Chance falls. Any win is also capped by Stake's maximum profit per bet.
What Win Chance Should You Choose in Primedice?
None beats the house edge. Worked out from the 99% RTP, a 50% Win Chance pays 1.98x and wins about every other roll; a 10% Win Chance pays 9.9x and wins about once in 10 rolls. Choose the swing your budget can absorb.
