I've been playing this iteration for two years. I'm at level 188, I've collected all of the puzzle pieces, and I've maxed the tiers for several of the prizes. However, my coin regen limit is still only 44. Also, there is no indicator on how to push the prize tiers to the platinum level. I'm assuming this is something that must be purchased? The sweepstakes feature is an annoying time waster. I stopped bothering with it over a year ago.
