HJG This is Montana Solitaire from Keith Vetter, with an added AutoPlayer, and some tweaks to fit the display better on a 1024x768 screen.
To save space, the common card images from card_img are used.
KPV Just curious, have you tried different strategies or noticed one being better than another? Ultimately, just how much skill is there and how much is it just mechanical?
HJG: it is a really simple, purely mechanical strategy:
There are some simple improvements / heuristics I can think of, e.g.:
gap xx 4h yy zz ...
should get the two of hearts, thus saving one move.
A more complex improvement: simulate all possible plays until the next redeal, building a tree of moves and note for each of these sequences of play how many cards are in their final position. Then select the best of these. This amounts to a complete enumeration, but I think the tree would be small enough to be feasible.
But, for testing such things, it would be nice to have selectable seed for the random numbers, and a dump-routine for the card-positions (logging), and record/replay of moves, etc. But that would need lots of additional code, and I wanted this version to get out as soon as possible :-)

Creating a tree with all possible plays is a big task. I tried it once for a Montana game I wrote for the Mac. I got a better clue on the Internet which got me just creating random moves over and over until no more moves were possible. Repeating this process would often find a solution in under 10s.
I like the auto player heuristic, I might try it out on games I know to have a solution from my own code. Note that the code I wrote would allow moves of a 2 to a new row, not sure if this is really totally right.
