I have been playing for months and have always been able to watch ads to refill things like the Wallet, rather than wait 6 hours for the timer. Last night I thought I'd buy the $2.99 piggy bank and get the 200 gems. WORST MISTAKE EVER!! Now I no longer can clear those timers with ads, it all has to be diamonds. Such a shame. I enjoyed this game. Now I'm uninstalling it. DO NOT BUY DIAMONDS. Be warned.
