An abstract game is a strategy game that minimizes luck and does not rely on a theme. Almost all abstract games will conform to the strictest definition of: a gameboard, card, or tile game in which there is no hidden information, no non-deterministic elements (such as shuffled cards or dice rolls), and (usually) two players or teams taking a finite number of alternating turns.
Many of the world's classic board games, including chess, Nine Men's Morris, checkers and draughts, Go, xiangqi, shogi, Reversi, and most mancala variants, fit into this category.
