For realz!
I played a boardgame with some other people earlier this evening. Goes by the name of Arkham Horror. The game allows for the possibility of adding dice to a roll that would otherwise be lost. In one turn I added three extra dice and rolled 1s on all, in all we lost 14 consecutive rolls with those extra dice (we obviously also lost with the regular dice), expending resources for nothing.
Just counting the extras that's a (2/3)^14 probability.
Something like that would never happen on CC, this is proof the dice are rigged!
