Any win chance · 99% RTP · instant rolls
Dicing is the oldest gambling game in RuneScape: a dice host rolls 1 to 100 and anything over 55 pays double. Here there is no host to trust. Drag the slider to whatever win chance you want, choose roll-over or roll-under, and the payout updates to exactly 99 divided by that chance. The x2 here is a roll over 50.50: a 49.5% chance to double your stake.
In game, dicing ran through a dice host in a clan chat. You traded your stake over, the host rolled a percentile die, and in the classic 55x2 a roll of 56 to 100 paid double while 1 to 55 went to the host. That is a 45% chance of being paid 2x, which returns 90% of what you stake: a 10% house edge, and that is before counting the hosts who simply kept a big pot. Jagex eventually banned dicing in game, and the demand moved to sites like this one.
The x2 on Dice is a roll over 50.50, or a roll under 49.50. Either one wins 49.5% of the time and pays exactly 2x, a 99% return. A 55x2 host paid double on 45% of rolls.
The formula is `multiplier = 99 / win_chance`, and the fact that it's 99 rather than 100 is the entire house edge - a flat 1% at every setting. That makes Dice the cleanest game on the site for testing a staking system, because the edge doesn't move when your strategy does.
The trust problem is gone too. The in-game host held every pot, and the roll was whatever they said it was. Here the roll comes from a hash committed before you bet, which you can verify yourself, and a win is paid the instant the roll lands.
Because rolls are instant and the range is continuous, Dice is also the game most used with the site's auto-bet - set a chance, a stake, and on-win/on-loss adjustments, and let it run.
You set a win chance and roll a number from 0.00 to 99.99. If it lands on your side of the target you're paid 99 divided by your win chance. There is no dice host and no trust involved - the number is derived from a seed pair you can verify.
Choose Roll Over and set the target to 50.50, or Roll Under at 49.50. That is a 49.5% chance, and a win pays exactly 2x. A 55x2 host paid double on 45% of rolls.
It is the classic dicing game run by in-game dice hosts: the host rolls 1 to 100, a roll over 55 pays double your stake, and 55 or under loses it. The name is the rule, over 55 pays times 2.
Not in game. Jagex banned dicing and later removed Duel Arena staking, so dicing for OSRS gold now happens on third-party sites, where the roll is decided by the site rather than by a host holding your GP.
Exactly 1%, at every win chance from 0.01% to 99.99%. It's the difference between the 99 in the payout formula and a fair 100.
Every round is generated from a server seed that is hashed and shown to you before you bet, combined with a client seed you control and an incrementing nonce. When you rotate your seed the old server seed is revealed, so you can replay every round it produced and confirm nothing changed after the fact.
Stakes are in Old School RuneScape gold (or RS3 GP), traded in game with a real host - not a token you can't cash back out.
