Minerva, in case you didn't know, is the Roman godess of wisdom. Someone in their wisdom decided to name a version of Solitaire after her. Good call.
If you like Athena Solitaire then you will love Minerva:)
Minerva Solitaire is essentially Athena Solitaire with a Reserve pile. The Reserve pile is on the right hand side of the screen. The Waste pile is displayed horizontally from the top left.
If you like games of Solitaire with Reserve piles, then this is right up there with the best of them. Other games with Reserve piles include Gloucestershire Solitaire which has not one but two and Demon.
By the way, I wrote my version of Minerva Solitaire following the rules as given in Politaire. I also allowed the Waste pile to 'splay out' as the cards are dealt.
On balance, I think that this adds to the game.
