ah shoot what are the rules to this one again? stack on identical cards, making a stack of just four collapses it and opens up a new free slot on top. collapse all ten to win. oh yeah but remember that there are eight main slots but ten suits. collapsing a set in a free slot doesn't give you a new one, though. i think there used to be a variable difficulty based on how many free slots you started with, but you don't need that, right? well good, because i didn't code that feature in
