Requires Lua 5.3+, Lgi, Gtk3, GooCanvas2. Also ImageMagick to create the card images as .png, unless you prefer to substitute some decent artwork for my horrible efforts (when I wrote the Tcl version of this, 20-odd years ago, I was on metered dialup and wasn't inclined to go searching for usable clip-art).
Click on card to select, click on destination to move (no dragging). Right-click to view a partially-covered card. Also, right-click on an empty depot moves a single selected card, rather than a maximal sequence. Double-click will move an eligible card to its foundation. Cards will be moved to foundations automatically, too. Hold down middle button to see allowed moves (note that moving an ace to a foundation and moving any card to an empty depot are not shown, they would clutter the display too much).
There is of course no undo function, but you can restart the current game from scratch.
The rules only allow moving one card at a time, but the program will compute most move sequences for you, using empty depots and exposed depot cards for staging. It will not currently compute move sequences that stage via the foundations.
