Cytosis: A Cell Building Game is a worker placement game set within a human cell. Players begin with several workers and during their turn, they position one worker at any open spot inside the cell. Certain spots grant players resources (e.g., mRNA, ATP); others grant actions (e.g., transform resources, gather cards). Resources are utilised to construct enzymes, hormones and/or receptors, which earn Health Points. The player with the highest Health Points when the game concludes wins!
