Is the probability of hitting the major prizes really higher in doing that than the daily 14 spins?
it is the same as rolling the dice game and the chances of you hitting the top prize there ($200) is similar (not the same) to chances of winning the big rewards by spinning the wheel of fortune. in other words it is a low chance that you can hit with 1 spin or never with a million spins.
I don’t think having high number of spins will increase your odds, as it’s probably fair and most importantly it’s luck based. Furthermore to illustrate more I have only hit 9999 once on freebitco, and post that I have been chasing it for 3 years now, and yet I have not been able to hit it, so you see in the end it all comes down to your luck and not the number of spins.
