Many of us love this game, but made difficult to play – Cooking Fever: Restaurant Game Review

Gems are a problem. There are too few ways to earn them. I've spent 20,000 coins at the casino and never got lucky to get one gem. I'll play for about 2-3 hours before I even get 7 gems and that's only good (practically) for one upgrade. I'll then buy gems (which I absolutely hate a game I can't earn what I need without buying them) but even at that, they go too quickly because the upgrades are so expensive. It's frustrating.
