Conclusion:
You can never beat the system. If it decides to screw you, you are screwed.
What ever you do you are gonna give it all to the house back (along with the winnings) in the long run from any of the Dice websites.
And this is exactly the reason I gradually move away from playing standard Dice, Slots or Roulette in favor of sports betting and Poker (despite me being totally awful at it so far).
I feel like with this types of gambling house has zero possibilities to fool me. I lose because I made a mistake or had no luck, not because it is designed for me to lose.
