There are many portals where you can play the Bitcoin dice, but most of them do not work with cubes. Instead of this attribute they use random numbers, for example, from 1 to 100. Further, participants should choose the figure that will be more or less the end result and they get a win, and the casino gets a percentage.
However, there is another, more realistic type: instead of get random numbers, players can throw the dices, as in a real casino. The number on which the bet will be made is based on the number that will be at once on two dices. That is, the maximum number could be 12 and the minimum is 2. At the same time, all the mechanics are not limited to the fact that you have a chance to correctly guess 1 out of 11.
In the dices the result can be totally unexpected, so they require a unique approach. There is a special option to check the results on many websites, so you can double-check the fairness of the casino.
