Just two weeks after purchasing Solitaire Engine by Runic Software I discovered GameBox Solitaire by PDA Mill which is, in my opinion, a vastly superior product. I'm upset that I threw my money away on Solitaire Engine, but the graphics and play on the GameBox one are awesome! It uses a landscape view so that the cards and layout can be larger. The music and graphics are incredible, and the animation when you win add a nice touch. It is now my favorite game on the Axim. Check it out here:
