A slight modification of the above game, and the related graph-theoretic problem, makes solving the game NP-hard. The modified game has the Rabin acceptance condition, and thus every vertex is colored by a set of colors instead of a single color. Accordingly, we say a vertex v has color j if the color j belongs to the color set of v.

Mitchell also cites a 1907 Spanish publication describing a guessing game similar to the use of paper fortune tellers. [20]

An inherent constraint in each game is the set of colors available to the players in coloring regions. If Left and Right have the same colors available to them, the game is impartial; otherwise the game is partisan. The set of colors could also depend on the state of the game; for instance it could be required that the color used be different ...
