Educational games are games that are designed to teach people about certain subjects, expand concepts, reinforce development, understand an historical event or culture, or assist them in learning a skill as they play. The types of games include board, card, and video games.
A board game is a game that involves counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. Games can be based on pure strategies, chances (e.g. rolling dice) 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 defeating 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 real-life situations can range from having no inherent theme, as with checkers, to having a specific theme and narrative, as with Cluedo. Rules can range from the very simple, as in tic-tac-toe, to those describing a game universe in great detail, as in Dungeons & Dragons (although most of the latter are role-playing games where the board is secondary to the game, helping to visualize the game scenario).
