Board games are traditionally a subset of tabletop games that involve counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. In common parlance, however, a board game need not necessarily contain a physical board. Some games are based on pure strategy, but many contain an element of chance and some are purely chance, with no element of skill.
Games usually have a goal that a player aims to achieve. Early board games represented a battle between two armies, and most modern board games are still based on defeating opponents in terms of counters, winning position, or accrual of points. (Source : Wikipedia)
