By far the worst slot app!! Most apps give lots of free coins to keep someone playing, not this one unless you set an alarm for every 2hrs for a measly bonus. Machine options suck, and have 20min bonus rounds that aren't worth sitting through. Paid $6.99 for 15mill coins and I couldn't even level up. Huge waste of time and $$. Only downloaded to get diamonds for Design home, my goal was level 26 and I've been on 22 for days. Rewards???Only good in Vegas. Don't download.
