10.000.000 bets equal running on Primedice for 10 months. Only simulation can do this.
It is just a simulation that can be used for possible happen in a particular bet but it doesn't mean there's a higher chance it will happen. Also with the algorithm use with this there's a huge chance that will get a good outcome with the game but again it is gambling can be unpredictable and luck it is just an idea to use for having an insight into the possible game like the demo mode.
