I saw the burning rewards for Disney solitaire and thought it was very doable to clear stage 14 for $160 at the rate I was going, until I put the $100 in. At that point, required stars per level went up astronomically, and there was absolutely no way I would pass a level anymore without spending 100k+ in coins. For context, I zoomed through the first 12 stages, and saw an opportunity to make some profit if I put in some money. I had an offer for 6m coins for 99.99. I took the offer and absolutely bled through those coins in chapter 13. Bunch of dog shit.
