Page "Strategy game" Paragraph 5

A purist's definition of an abstract strategy game requires that it cannot have random elements or hidden information.

This definition includes such games as Chess, Go and Arimaa ( a game with multiple moves within a turn ).

However, many games are commonly classed as abstract strategy games which do not meet these criteria.

Games such as Backgammon, Octiles, Can't Stop, Sequence and Mentalis have all been described as " abstract strategy ", despite having a luck element.

A smaller category of non-perfect abstract strategy games incorporate hidden information without using any random elements.

An example is Stratego.
