This is a strategic dice placement game for 2 - 4 players. Each player takes the roll of a strain of bacteria in a petri dish, and begins to mutate and grow their strain in an effort to be the biggest. Every turn you roll two D6 spotted dice, and then place one of these on the board according to a set of simple rules. Do you extend your strain or do you focus on breaking apart an opponents? Do you risk expansion into a contested portion of the playing area or do you focus on strengthening, but not lengthening, your strain? Every turn has interesting and strategic decisions to be made all from a simple roll of two dice.
