Russian Solitaire is a complex game that is hard to win.
The goal is to move all the cards to the foundations in ascending order by suit.
You can grab one or a group of face-up cards from the tableau and move them to another tableau pile, as long at the first card in the set is one less in value and of the same suit as the top card in the set.
When you dig down to a face-down card in a tableau pile, you can click it to turn it over.
When a tableau pile is empty, you can move a king or a set of cards starting with a king to fill the space.
