This game has a HUGE selection of card games. But that's it. There is nothing special about this collection. And they all need a lot of work. There are tons of options missing. And a lot of the games have missing rules. The developer needs to play a few other card game collections to see what I mean. (Not too many on Steam to take example from. Might want to look at some well developed mobile games, like Card Shark Collection on iOS or Android for example.)

There is no UNDO option in the solitaire games.
No option to turn off auto-flipping the cards.
No option to see the discard spread. (Can only see top card. Klondike deal-3 for example deals 3 cards. but you can't see the 2 underneath.)
Some games are missing the ability to take the discard pile, flip it back over, and go thru it again. (Klondike seems to be the only one that allows you to do this. Pyramid and Spider are missing this, probably more.)
Some games are bugged like Pyramid. (I went to drop a Jack on a 2 to remove it from the pile and it simply removed the Jack. Then I went to drop a 9 on a 4 and for some reason it took the 6 next to it. 9+6 does not =13.)

But the most important thing that is missing. Deal animations. The cards simply change instantly. You can't see them moving into position. Which can lead to confusion sometimes as to what happened. [Deal animations have been standard in card games for at least 15 years. Not sure why that was left out. It a big one.]
