It's addicting but the AI cheats, and that makes it way less fun. It's very frustrating to constantly lose and waste energy to a cheater. Even when playing against live competitors It's like the game knows when you don't have a lot of coins so it gives the other players the perfect cards so you lose and have to buy more coins. Waste of my time at this point. Will be deleting as soon as I've reached my goal through the "Current" app.
