Their signature app, Cardshark Collection, hasn't been updated for almost 2 years. The majority of their games are solitaire names that are well known, such as Klondike, Crescent, Pyramid and others. Solitaire players depend on, and want, a very few things from the games they play: consistency and more wins than losses. This collection delivers neither one. If fact, many of the games, at least this companies versions, are totally unwinnable, and I've been playing solitaire games for decades.
I've written several times using their "contact us" link with no response. Imagine that-no response from a company whose app hasn't been updated since September 2017.
If you're looking for a good suite of games that's enjoyable and provides more wins than opportunities to curse, look somewhere else.
