Shuffle Cats, a new game from King (makers of Candy Crush saga and other titles) has you playing its variant of the classic card game rummy, called "regal rummy", with the computer or other players. It has glitzy, good-looking graphics and features multiple cute cat characters. It's supported by micro-transactions, which let you buy a variety of powerful cards or more gems to play the game with.
The house usually wins
Unfortunately, Shuffle Cats does have its difficulties. It costs the game's own currency just to play matches, even consecutive matches in the same room. When playing against the computer, it can be very difficult to win until you get the hang of the game. The gameplay is overall a lot more enjoyable if you're willing to buy a couple in-game items to make your life easier.
Try your luck
Overall, Shuffle Cats is a nice game to try and a fairly nice game to play, depending on your tastes and patience. Since it's free, there's not much to be lost but a bit of time for giving it a shot. The aesthetic won't appeal to everyone: even cat lovers might find some of the cats more uncanny than cute. But there's a variety of cats, and a variety of players, too.
