I just located this game, and was having fun, so I began building up the gems and cash, and to my surprise, items like $3.49, and $1.99, was all charged $6.99 for every purchase. First 2 purchases were small and here I see 4 purchases at $6.99 + state tax + local tax,2¹ equalling $7.60 x4. one was $13.99, and then I went to check my bank acct and those weren't all $7.60! I had clothes picked out, + now I worried about spending from the gems and money in the acct to purchase anything else!

Love love love this update. The ability to share cups boosters within guild is huge, especially for those guilds (like mine) with many new and newer players. Love the new Searchlight - it feels very Frankenstein-ish. And the rewards for the one day are much better. Extremely excited about the new island! I can't wait! The only issue I noticed is that all of my points aren't being collected again in tournament. So far it's been a small amount, but that issue had seemed resolved previously.

Love this game!. In addition to the main quests there is a variety of mini games. Best part absolutely no ads! And no money required to purchase items needed for new levels. They always give an alternative way instead of cash money to earn what's needed to move on to new levels. And simply put, the more you play the better and faster you get which earns you even more without dumping a bunch of money into the game especially for us that don't have it but still love to play! For that many thanks!
