Jet Set Willy Solitaire is a themed version of Klondike.
As you can probably guess (if you like retro computer games), it is themed in the style of the old Jet Set Willy and Minic Minor games.
The themes, in case you didn't realise, and really a way of me scratching the programming itch:)
I don't used typescript or any sophisticated javascript on Solitaire Online but experiment more with old school design.
The aim of this particular challenge was to create multiple Jet Set Willy type screens using as few lines of code as possible (while still being more or less readable).
