It can also be generalized as an nd game, specifically one in which n = 3 and d = 2 Typically as many plies from the current position as it can search in the time available. [6] it can be generalised even further by playing on an arbitrary incidence structure, where rows are lines and cells are points.
Games like nim also admit a rigorous analysis using combinatorial game theory With perfect play, and from any initial move, both players can always force a draw Whether a game is solved is not necessarily the same as whether it remains interesting for humans to play.
The game can also be generalized as a n d game [2] the game can be generalised even further from the above variants by.
