Shuffle Cats is Rummy with online multiplayer (and cats) by the makers of Candy Crush Saga
House of Cats
You have to know about King by now. They made hugely popular titles like Candy Crush Saga and were then bought by Activision for $5.9 billion.
They still rely a lot on the popular matching game though and it's understandable that they'd try to expand their portfolio as much as they possibly can. Something Rovio tried but ultimately failed to do.
King's latest title isn't exactly new for those looking at games soft launched. Released in some countries at the end of last year, Shuffle Cats is an online card game based on Rummy.
To gain points against your opponent you need to "meld" cards either by placing three or more cards with the same value or by placing three or more cards that create a sequence.
It seems like a rather standard take on the game with the notable strategic element of choosing cards from either the discarded pile or the top of the deck. This means that you'll have to be careful when discarding cards.
