Spider Solitaire: Could Not Have Solved The Games Without An Excel Spreadsheet

I play Vista spider 2 suits (intermediate). I have solved the first 516 games (and still going). I read somewhere that all 2 suit games are solveable. I could not have solved the games without an Excel spreadsheet that I developed that does not solve the games but helps you solve them by keeping track of the cards you have managed to expose. I only use it on the hard ones but without it I would have given up on many. I would be happy to share it with anyone who is like me and is determined to solve every game. It has an easy way to enter the cards.
