Micromondo

Microworld is a challenging game for two players in which one player is a virus and the other controls antibodies. On your turn, you place a tile next to the tile your opponent has placed on the previous turn. Special tokens on the board can be collected and used any time as a special action. You score points for your own tiles in the neighborhood, and at the end of the game you score for a majority in each area of the microworld!

The game has eight modular rules that change the gameplay, and these rules can be combined in any way desired.
