my fiancé and myself have this game.
I has 2 modes, spider and klondike
klondike easy mode lets you stack empty spots with any card not just kings.
The cat card design is the only one you get.
On the DSi/3DS menu when you select the game it will tell you win ratio .
That's pretty much it, a very bare bones yet fun game. The easy mode I really like because sometimes solitaire is impossible and this allows it beatable almost every time. I don't think its worthy of coins because its only $2 to buy it.
