As you flip the cards over, you set them into piles based on the suit (so if you flip over your first spade, it goes into a new pile. Then draw a club, and it goes into its own new pile as well. If you draw a spade again next, it gets placed on top of the first spade to show two have been drawn). And once one pile has all five cards of its suit in it, the game ends. So it could be a short one, only 5 cards long, or it could be up to 17 cards if you draw 4 of each before a fifth of any type, or more likely somewhere in the middle :D Thanks for the question, I should get clearer about that :D

Hurray, thank you so much! It was fun to make, too, so I hope to make more versions in the future :D
