Consider a 2×2×2 three-dimensional matrix for a mixed extended game. The set of Nash equilibria (red) in a particular game is determined by the intersection of the graphs of best response mappings of the yellow, blue, and green players.

Details

Sliders define the elements of the 2×2×2 matrices: A, B, and C, and the opacity of the players' graphs. First mixed strategies of the players , , and ) are used for the graphical representation of the set of Nash equilibria. The value of the second strategy of every player is simply , , and .
