FreeCell played on a computer is different than freeCell played IRL. Whether IRL or virtual, I find it therapeutic as I explore the transition from initial to final states. My iPad's virtual version has an interesting feature: Cards that can be played to a foundation will automatically play unless a lower ranked card is locked inside a cascade. This along with the ability to reset to the initial state of play allows me to explore in great detail each game's topology.

          Once in a great while the initial state is particularly elegant:

in that it allows an intermediate state for which all but one tableau begins with a King aligned with its corresponding foundation and all but one of those is of equal length.

          Moving the string pinning the Heart's Ace to the left most tableau sets off a most satisfying ballet of cards as the foundations smoothly build to their final state.

          I cannot pass up the opportunity to state one tiny political point: Right Wing Nuts would really lose it if they knew I actually got payed (as in: Your tax dollars at work, paid!) to contemplate this sort of stuff. All my "working" life I did this sort of thing. It is amazing the number of ways you can learn/teach physics particularly elementary particle physics while playing games and working puzzles.
