"Strain brings the world of organisms, viruses and bioengineering to your table in a very fun way. The game is very contagious, but don’t worry, you won’t be catching the viruses! Gameplay
Your goal is to complete enough organisms to be the first to score 12 victory points. The turns are simple; draw three tiles, build up your organisms and/or attack other players, score completed organisms and then discard down to four tiles.
There are three different types of tiles; Organism, Cytoplasm, and Petri Dish tiles. You can play one organism and cytoplasm card for free each turn, but the Petri Dish tiles usually require resources to play."
