Darn It!! is a card game that's simple to play, hard to win - and very addictive!

Place the deck cards in a 4x4 grid. When the grid is full, remove pairs that add up to 10.

Kings, Queens and Jacks must be placed in the corners, at the center of the top and bottom rows, and at the center of the left and right columns, respectively. They cannot be removed.

The goal is to play all 52 cards in the deck.
