Some domino connecting games use a matador matching rule, in which the spot value of touching tile ends has to add up to a fixed total. Traditional matador games are played with a double-six domino set, and touching ends have to add up to 7, so that for example if one of the open ends is a 2, the next tile played on that end must begin with a 5.

In the double-six set there are four matadors: these are the double blank and the tiles whose ends add up to 7, i.e. the [0:0], [6:1], [5:2] and [4:3]. Matadors are wild tiles in the sense that they can be played on any open end of the layout in either orientation. If the layout has a blank at an open end the only way to continue that arm is with a matador.

Matador matching can in principle also be used with larger domino sets. The equivalent rule when using an [n:n] set would be that touching ends must add up to n+1 and that the tiles whose ends add up to n+1 together with the double blank are wild matadors. For example in a double nine set there would be six matadors: [0:0], [9:1], [8:2], [7:3], [6:4], [5:5].
