Dice
Dice is the most honest game in the Jacks Club originals set, because it shows you the house edge in the interface. Most casino games ask you to trust a published return figure. Dice hands you the arithmetic and lets you check it before every roll.
Here is how the game works, what the numbers on the panel mean, and how to read the 2% edge straight off the multiplier.
How Dice works here
The game rolls a number between 0.00 and 99.99. You do two things before it rolls.
First you choose a direction. Above means you win if the roll lands higher than your target. Below means you win if it lands lower. Second you drag the slider to set the target itself.
Three fields update live as you move it. Roll Over or Roll Under is your target number. Win Chance is the percentage of outcomes that pay. Multiplier is what a winning roll returns. Change any one and the other two move with it, because they are all the same fact expressed three ways.
The published return to player is 98%, the same figure carried by Keno, Mines and Hilo.
The 2% edge is visible in the multiplier
This is the part worth understanding, and it takes one line of arithmetic.
The multiplier on every setting is 98 divided by your win chance. A fair game with no edge would divide 100 by your win chance instead. That gap of two points is the entire house edge, and it is sitting on screen in front of you.
Read off the game at four settings:
Win chance 50%: pays 1.96x. A fair coin flip would pay 2.00x.
Win chance 26%: pays 3.769x. Fair would be 3.846x.
Win chance 97%: pays 1.01x. Fair would be 1.031x.
Win chance 1%: pays 98x. Fair would be 100x.
The shortfall is 2% at every single one. Not 2% at the safe end and 8% at the risky end, the way a slot's volatility can disguise things. Two percent, everywhere, always.
That is unusual enough to say plainly: you do not have to take the 98% on trust, because you can derive it from any setting on the panel. Divide the multiplier into 98 and you get the win chance back.
What the slider actually changes
It changes variance and nothing else.
Rolling at 97% win chance for 1.01x means you win almost every roll and gain almost nothing when you do. Rolling at 1% for 98x means you lose almost every roll and occasionally get a large return. Both settings hand back the same 98 cents on the dollar over a long enough run.
So there is no clever spot on the slider. There is no setting where the maths tilts. What you are choosing is how long your balance survives and how dramatic the swings are on the way, which is a real decision about how you want to spend an hour, just not a decision about value.
Bitcoin Dice
Dice takes the same balance as the rest of the site, so a Bitcoin deposit funds it directly with no conversion step. Jacks Club is crypto only, with BTC, ETH, LTC, USDT, USDC, XRP, TRON, TON and SOL all accepted.
Dice rewards a particular funding habit more than most games, because of how fast it runs. A roll resolves instantly and players get through hundreds of them in a sitting. A network fee is charged per movement rather than as a percentage, so one deposit that covers a whole session costs the same as one that covers ten rolls. Topping up repeatedly is the expensive way to play a fast game.
If the coin price moving underneath you is a distraction, deposit in USDT or USDC. A stablecoin means the only thing changing is the game. That matters more at the low win chance settings, where you can sit through a long losing run before a 98x lands, and you would rather not be tracking two things at once.
What 98% RTP costs over a session
A 98% return is a 2% house edge on every roll, and Dice is fast enough that the turnover adds up quickly.
Roll 1 dollar a time for 500 rolls and you have wagered 500 dollars. The edge on that is about 10 dollars. Roll 1 dollar for 2,000 rolls, which is an ordinary evening at this speed, and the expected cost is about 40. The per-roll cost is tiny and the per-hour cost is not, because the number of rolls is doing the work.
This is the honest argument for a slower setting rather than a faster one, and it has nothing to do with luck. Fewer rolls means less turnover, and less turnover means less edge paid. Our RTP and house edge guide works through the same maths across the rest of the catalogue.
Why dice strategies do not work
Every roll is generated independently. The game has no memory of the last one and no plan for the next, so a run of reds changes nothing about what comes next.
The martingale, doubling after each loss, is the system people bring to Dice most often. It does not fail because of bad luck. It fails because of the table maximum and your own balance. At 50% win chance a run of ten losses is roughly a one in a thousand event, which sounds rare until you remember how many rolls an evening contains. Ten doublings from a 1 dollar base needs 1,024 dollars to place the eleventh bet, and it is risking all of that to win the original 1 dollar back.
Anything sold as a Dice predictor is a random number generator with a subscription attached. A tool that could genuinely predict the roll would break the game rather than sell access to it.
Common questions
What is the best win chance to play at? There is no best. Every setting returns the same 98% over the long run. Pick the variance you want.
What is the highest Dice multiplier? 98x, at a 1% win chance. The lowest is 1.01x at 97%.
How do I know the 98% is real? Divide 98 by any win chance on the panel and you get that setting's multiplier. Check it at three or four points and the edge is confirmed without taking anyone's word for it.
Is the game provably fair? Yes. Each roll comes from a seed pair you can verify yourself rather than a number you are asked to trust.
Can I play Dice with Bitcoin? Yes, and with any of the nine coins on the site. There is no fiat option, so every roll is funded in crypto by design.
Does rolling above or below change anything? No. They are mirror images. Above with a target of 1 and below with a target of 99 are the same bet at the same price.
