A board game is a game in which counters or pieces are placed, removed, or moved on a premarked surface or "board" according to a set of rules. Games may be based on pure strategy, chance or a mixture of the two and usually have a goal which a player aims to achieve. Early board games represented a battle between two armies and most current board games are still based on beating opposing players in terms of counters, winning position or accrual of points (often expressed as in-game currency).

There are many different types and styles of board games. Their representation of a real life situation can range from having no inherent theme, such as Checkers, to having a specific theme and narrative, such as Cluedo. Rules range from the very simple, such as in Tic-tac-toe, to ones which describe a game universe in great detail, such as in Dungeons & Dragons, although most of these are Role-playing games and the board is secondary to the game, serving to visualize the scenario. The length of time it takes to learn to play or master a game can vary greatly from game to game. Learning time does not necessarily correlate with the amount or complexity of rules; some games, such as chess and Go, have simple rules that can still lead to complex scenarios.
