Welcome to Joy Card. This is a card game where the objective is to get as many runs and sets as you can in the fastest time you can. There are many different ways to play and win, so be ready to explore and try them all!

The game begins with each player receiving 13 cards. From these, they must form valid combinations and sequences to complete their hands. 

Once a player has formed a valid hand, they can declare a winning streak. If the other players also have a winning streak, then the game is over. If the player has a winning streak, then they can add the highest card to their hand.
