BigFreeCell is like FreeCell with two packs of cards.
There are a lot of cards on the screen. Eight Foundations, eight Cells and ten columns with every card from both packs dealt.
I've done my best to scale everything, but even so full screen works best on my Mac.
It also takes a long, long time to play, so I'd recommend a coffee and snack before starting.
