Farm Mania 2, much like Farm Frenzy and FarmVille, lets you manage a farm.
Positions of items (animals, crops, etc) are fixed and numbers are limited. The game is played in levels, each level requiring a specific amount of given items to be sold.
Originally this game was produced by Realore Studios and Big Fish Games and available only via their websites. Later is also was made playable on many free game sites, usually as a flash game, sometimes as Downloadable content.
Farm Mania 2 is the second in a series of (so far) three.
