Can you imagine playing a game in a bacteria-infested environment Well its not really that scary playing Bacteria Solitaire. Its just playing solitaire with a friendly host of bacteria to be precise. These amiable bacteria monsters will accompany you while you play the classic game of solitaire. The rules of play are identical to standard solitaire where you are required to fill up the four slots at the top right hand corner of the screen with ascending order of each shape of cards starting from an Ace. And to do that you have to form alternately colored rows of cards in the playing area and this has to be done in descending order. While shifting the cards around to form these rows you will be exposing the hidden cards which can be then opened. There is also a stack of cards at the top left corner that you can use to get new options once the movement of cards in the playing area becomes stagnant. And when you get all the four slots of different shaped cards filled you win the game. Bacteria Solitaire adds that extra nerve-wrecking touch to the engaging game of solitaire. Those little creatures are quite the companions for a round of card games really.
