One-Handed Solitaire is a solitaire card game played with a traditional 52 card deck.
Initially 4 cards are drawn from the back of the deck and placed face up.
If the first and fourth card are the same suit, discard the two middle cards to discard pile.
If the first and fourth card are the same number(rank) discard all four cards.
The game always has last 4 cards in play so if there are previously drawn cards and their count is more than or equal to 4, repeat the process of discarding.
If there are not enough cards to do this, draw one card at a time from the dealer deck.
Repeat this process of draw and discard until end of the deck is reached. If all cards are discarded, you win the game.
