Cytosis: A Cell Building Game is a worker placement game that occurs inside a human cell. Players begin with a number of workers and on a player’s turn, they will place one of their workers in any available location within that cell. Some of the locations give players resources (e.g., mRNA, ATP); some with actions (e.g., convert resources, collect cards). Resources are used to construct enzymes, hormones and/or receptors, which score Health Points. The player with the most Health Points at the end wins the game!
