InstaSolitaire has the same rules as Klondike solitaire that you might remember playing with grandma or on your computer.
The goal is to move all the cards from the tableau up to the foundation piles in the upper right. To place a card on the foundation, it needs to be the same suit as that foundation in ascending order. We start with an Ace, then 2, and so on.
On the tableau, players can build on the rows in descending order, but the card also needs to be of the opposite color. For example, players can play a Red 5 on a Black 6. If an empty row opens up, only a King of any suit may be played, to start a new row. The sorted sections of a row may be picked up and moved to a new row.
The stockpile stack is on the upper left. Players can flip though those cards to find cards that will help them sort their rows on the tableau. If players go through the entire deck, they can tap the empty space to go through the stock again.
The game can be expanded to full screen by clicking on the double arrow icon on the upper right.
