I do save them from time to time up to 10 spins,and other times use 1 as soon as i get it...and it works out the same for me i'll get 2 major wins if i spin 10(normally)and using 1 at a time i'll get a major win within 6 different days...you notice the junk prizes more if you do it day by day as it seems to stretch out longer thats all.
