Crypto dice 101


    The reason dice is so popular is because it’s so simple. Here is how it works, step 1, 2 and 3 can be done in any order.

    1. Enter your bet size.
    2. Enter a number between 0-100 you will bet to roll over or under.
    3. Selecting if you want to try to roll over or under the number you selected in step 2.
    4. Roll a number between 0-100.
      • If your bet wins you get paid according to the bet’s probability less the house edge.
      • If your bet loses there is no payout.


    Bet size: 1 m฿
    Number to roll over or under: 50
    Over or under: Over

    Case 1 – Roll: 78
    78 is over 50 so your bet won. It had a 50% probability, the house edge is 1% so your payout is 1.98 m฿ and you won 0.98 m฿. See how that is calculated below.

    Case 2 – Roll: 12
    12 is under 50 so your bet lost. There is no payout and you lost 1 m฿.

    Payout, profit and house edge

    The site will show the potential payout or profit for any bet parameters you enter, before you make the bet. To understand it fully there are 3 components;

    Bet amount
    You set this.

    This is ease to work out because the possible range of roll outcomes, 0-100, matches perfectly to percentages.

    Where x is the number you will choose to roll over or under. You have x probability of rolling under x, for example.

    • Rolling under 50 is a 50% probability
    • Rolling under 70 is a 70% probability
    • Rolling under 30 is a 30% probability

    You have 100 – x probability of rolling over x, for example

    • Rolling over 50 is 50% probability
    • Rolling over 70 is 30% probability
    • Rolling over 30 is 70% probability

    House edge
    This is almost always 1%, which gives a payout of 99% of probability.

    Payout multiplier

    You can work everything out with the 3 things listed above but to make it simpler we combine the probability and the house edge to give you a payout multiplayer. The payout multiplier is

    (Payout % / probability of winning)

    Almost every crypto dice site has a 1% house edge. This means you will get paid out 99% of the probability of winning. Lets say you bet that you will roll under 25, you have a 25% probability of winning so your payout multiplier will be

    99 / 25 = 3.96

    Payout calculation

    Bet amount * payout multiplier = payout

    So if you bet 2 m฿ with a 3.96 payout multiplier your payout will be

    2 m฿ * 3.96 = 7.92 m฿


    Remember that 2 m฿ of that payout was yours to start with so subtract it from your payout to work out your profit.

    payout – bet amount = profit

    For this bet

    7.92 m฿ – 2 m฿ = 5.92 m฿

    So the full profit calculation is

    bet amount * (payout %/chance of winning) – bet amount = profit

    For this bet that is

    2 m฿ * (99/25%) – 2 m฿ = 5.92
