It's a game where you draw all the cards in the deck.
1.The deck selection screen.
And when you click on a deck, you'll see the deck information as shown below.
2.The play screen.
When the hearts in the center left disappear, it's game over. And the number above it is the number of cards currently left in the deck.
Additionally, if you right-click on a card anywhere, a detailed description will appear, as shown below.
3.Use a card
Drag a card and drop it in the blue area on the right to use it. After playing a card, draw a card so that you have a 2-card hand.
4.Using with Sets
Drag a card and drop it into the red area on the left to set it. Sets don't draw cards, and set cards are destroyed when the number displayed above them reaches zero.
5.Clear
Once you've drawn the entire deck, you'll see the next screen, and you're clear!
