Practical Guide
Fun but frustrating. They don't give you the rewards you repeatedly win. They've kept me at 1 gold bar under what I need to continue... for months, and now they're offering more turns if I pay. I've earned a ton of bars, but never receive them. That's how they force players to buy more, using real money of course. And there are a ton of screens to navigate between levels, between re-attempts, between everything. Also when you watch an ad in order to continue, half the time they freeze.
