The board game is a small genre based on tabletop games. Mechanics consist of moving pieces on a board and placing them according to a set of rules. Some platforms provide online matches with thousands of users playing all at once. Board games can function as virtual tabletop programs that allow trying multiple types of boards. There are generalized programs like Vassal, Tabletop Simulator and Tabletopia; programs like Roll20 and Fantasy Grounds are more specialized for role-playing games. The players can add extra content through user modifications.
The usual goal is to defeat opponents in counters, gain points and win a position. Their representation and design differ, sometimes they have an inherent theme, like checkers, or even a particular theme and narrative, like Cluedo. Rules can stay the same throughout the game or change little by little, like Tic-tac-toe.
