These solitaire games are the same as the original DKM Solitaire ones, except that they have been rewritten to run without Flash. This means that they are also available on mobile devices.

 

FreeCell Rules Popular favourite which is 99% skill.
Klondike Rules Classic solitaire - one card turned from stock at a time.
Yukon Rules Similar to Klondike but all cards dealt initially and can move cards even if not in sequence.
Eight Off Rules Good variation of FreeCell with eight free cells but you must build down in suit.
