Cultivate fluorescent colonies on a 7×7 slide. Three bacterial sources (red, green, and blue) are fixed in the dish, while gray target wells are randomly scattered. Select a stained square and spray spores in four directions: empty squares will attach the same color; collisions with other colonies will mix to form yellow, purple, and cyan, and the colonies will divide in four directions, up to two layers. Spores hitting the edge of the dish will dissipate. The dish is complete when all target wells are covered.
The application provides thirty-six campaign slides, daily dishes sown by date, unlimited open stages, as well as spectral controls, experimental reports, and field notes. Completing a level adds entries to the local culture log and unlocks the specimen cabinet. Suitable for players who enjoy discrete rules and short matches, allowing them to complete a culture dish during their commute.
