Solo Canasta

I enjoy Canasta, but sometimes no one else is interested in playing with me. So I created this easy-to-learn set of rules for playing Canasta by yourself. Every turn, the choice is yours: which set do you build up, and which cards do you have to let go? Can you get the necessary natural canastas? Will you have too many unmatched cards left over? Watch out for those crazy 3s, the red ones can help you out a lot, but the black ones can mess up your plans!
