Evilution

From BoardGameGeek:

Evilution is a solo, dice-rolling game of mathematical thinking. You play as an unseen force striving to facilitate the successful evolution of a woman recently injected with a scientifically modified alien organism. Strategically apply addition, subtraction, multiplication and division to the values of your rolled dice to connect DNA Strands while also blocking Mutagen Cells.
