Gay Gordons (solitaire)

Rules

It is played with a standard deck, with jokers removed. Ten piles of five are dealt face up, with two reserve cards also face up. In both the top card is in play and the piles cannot be refilled or built on. Empty piles cannot be refilled. The aim of the game is to remove all cards by making pairs that add up to eleven (suits are not important). Kings pair with queens, jacks with other jacks, and aces with tens.
