Oh dear, this game's hard!



You can attempt to play Beleaguered Castle Solitaire in the Shoebox in amongst the card games.

The rules are simple enough. Grab a single card at a time, and move them from the "Walls" into the "Foundations".
The foundations go Ace to King, in ascending order, in the same suit, whilst you can stack Wall cards in descending order, without worrying about their suit. Only the "topmost" card of each wall pile is movable.

It was a really simple game to code, and only took about an hour or so before the game was pretty much playable, at which point I attempted to play it.

Shockingly hard!!
I rechecked all the game rules on a variety of different websites, and they all seemed to be suggesting the same rules that I'd coded, so..
.. I guess this is just a hard game to play, then!

Good luck!
