A patience game I invented back in the 1970s. Quick to play but quite challenging. I claim the copyright for any commercial use but non-commercial remixing etc is OK by me. Large deck copied from BoltBait's cribbage solitaire. Small deck is my own. Paddle2See suggested adding a scoring system. Having considered that I think the number of cards left in the stack gives a score which you're trying to minimise and if you get it to 0 you're trying to minimise the number of piles left. So you can already compare one attempt with another.
