In M-Theory, a brane is an object “that generalizes the notion of a point particle to higher dimensions.”

In set theory, an Mbrane is a matrix of matrices that generalizes a value in n dimensions.

The classic “Sudoku” configuration is a set of values 0 through 8 on a 32(32) matrix, thus nine values in 2 dimensions.

In gamer parlance, a Mbrane is an app that runs [M] games.

Although humans can only easily play on  Mbranes in 3 dimensions, for automata, the matrix may be extended to mn(mn), thus the n dimensional game.

Mbranes are not restricted to supersymmetrical configurations, and may be extended into any matrix of matrices.
