Stem Cell

Evolve. Enclose. Dominate.

Stem Cell is a deep hex-grid strategy board game by Randall Blanchette featuring a seamless toroidal (wrap-around) board, genetic strand drafting, and Rock-Paper-Scissors cellular combat. Play solo against AI, learn via the interactive tutorial, or compete in live and async online multiplayer.

Core Mechanics

Genetic Strand Coding Blocks: Each turn, expend one coding block from your strand to USE its active symbol (move, attack, or upgrade a cell), EVOLVE into a new block (+1 PT), or REMOVE a cell back to reserves.

Cellular Combat Hierarchy:

Stem (●) defeats Immunity (■) by moving into the hex and destroying the occupant (+1 PT).

Immunity (■) defeats Viral (▲) by converting the target hex into a copy of itself (+1 PT).

Viral (▲) defeats Stem (●) by converting the target hex into a copy of itself (+1 PT).

Toroidal Enclosures: The edges of the board wrap horizontally and vertically. Surround empty hexes with your cells to form Enclosures, scoring +1 PT for every enclosed hex at the end of each round.
