Roobet Dice: how it works, odds and settings

Roobet Dice is one of the house games Roobet builds itself, listed in its help centre alongside Crash, Mines, Towers, Plinko and the rest of its originals. It is the simplest of them: a number is drawn between 0 and 100, and you win if it falls on your side of a line you set.

That simplicity is the appeal. There are no reels, no bonus rounds and no animations to wait for. You choose how likely you want a win to be, and Roobet pays a multiplier that reflects that chance minus a small house edge. Independent reviews widely report Roobet Dice at a 99% RTP, which makes it one of the lowest-edge games on the site, on a par with Plinko and well ahead of most slots.

Like Roobet's other originals, Dice uses a provably fair system, so each roll can be checked after the fact. The game sits in the Roobet Originals section; our originals guide covers the rest of the line-up.

1. Set your bet amount. Reviews report a range from $0.01 up to a large maximum per bet; the live limits are shown in the game.
2. Move the slider to set the target number. The green part of the bar is your winning range and the red part is losing.
3. Choose over or under. Flipping the direction swaps which side wins and keeps the same chance if you mirror the number.
4. Read the win chance and multiplier. The game shows both and updates them as you move the slider. You can also type a multiplier or a win chance directly.
5. Roll. The result appears immediately and your balance updates.

Some guides describe extra modes on Roobet Dice, such as rolling between or outside two values. Whatever the mode, the principle is the same: the payout is set by how much of the 0 to 100 range counts as a win.

With a 99% RTP, the multiplier follows a simple formula:

Multiplier ≈ 99 ÷ win chance (in percent)

Some examples:

The 1% that makes the difference between 100 and 99 is the house edge. It applies at every setting. A 90% chance at 1.10x and a 10% chance at 9.9x have the same expected return per bet: 99 cents for each dollar staked.

What changes with the setting is variance. High win chances give a smooth balance line that drifts down slowly. Low win chances give long losing streaks broken by big wins. Neither changes the long-run result; they change how the ride feels and how quickly a bankroll can disappear.

Roobet Dice includes an autobet mode that places rounds for you. Typical settings are:

• Number of bets. How many rounds to play before stopping. Set it; do not leave it on infinite.
• On win / on loss. Reset the bet to its base, or increase it by a percentage. Increasing on loss is the Martingale family; increasing on win is a reverse Martingale.
• Stop on profit. End the session once you are up a set amount.
• Stop on loss. End the session once you are down a set amount. This is the most useful setting in the panel.

Autobet runs fast. Hundreds of rolls can pass in minutes, and the house edge works per roll, not per minute. A strategy that looks harmless at one bet a minute behaves very differently at several bets a second.

Martingale

Double after every loss and return to the base bet after a win. Each cycle wins one base bet, until a losing streak exhausts your bankroll or hits the bet limit. At a 49.5% chance, ten losses in a row happen roughly once in every thousand sequences, and that sequence costs about a thousand base bets.

Reverse Martingale (Paroli)

Increase after wins, reset after losses. It caps losses at the base bet but gives back most winning runs.

Low-chance hunting

Playing 1% or 2% chances in the hope of a 50x or 99x hit. Thrilling, but streaks of 200 or more losses are normal.

High-chance grinding

Playing 90% or more for small, steady wins. The balance looks safe until a few losses wipe out dozens of wins.

Every one of these changes the shape of results, not the expected return. Over enough rolls, every system converges on 99%. Treat any Dice "strategy" as a way to choose your risk, never as a way to profit.

Roobet's originals are provably fair: before you play, the game commits to a hashed server seed; your client seed and a nonce (a counter for each bet) are combined with it to generate each roll. After you rotate to a new server seed, the old one is revealed and you can recompute past rolls to confirm they were not altered.

In practice:

1. Open the fairness or provably fair panel in the game and note the hashed server seed and your client seed.
2. Change your client seed if you want; it is yours to set.
3. Play, then rotate the seed pair to reveal the previous server seed.
4. Use the verifier to recompute a roll from the seeds and nonce.

Provably fair proves the result was fixed before you bet. It does not change the house edge. See our provably fair guide for the method in more detail.

• Decide a session budget in advance and set a stop-on-loss in autobet to match it.
• Use a flat bet size rather than a progression. It keeps losses predictable.
• Choose your win chance for comfort, not profit. Higher chances mean longer sessions on the same budget.
• Know the rakeback. Dice wagers earn RooWards Instant Rakeback like other games, but rakeback returns a fraction of the edge; it does not turn Dice into a winning game. See Roobet VIP.
• Mind bonus wagering. Dice is reported to count only 10% towards deposit-bonus wagering, so it is a slow way to clear a bonus.
