Crypto Dice 101

crypto dice 101


The reason dice are so popular is that it’s so simple!
Here is how it works, Steps 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 is won. It had a 50% probability, and 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 is 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 easy 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 a 100 – x probability of rolling over x, for example

  • Rolling over 50 is a 50% probability
  • Rolling over 70 is a 30% probability
  • Rolling over 30 is a 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 99% of the probability of winning. Let’s 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
