A recent innovation is the "mix-max" or "mixed max" tournament, in which the table sizes vary during the course of the event. A typical example is the mix-max event held at the 2012 World Series of Poker, in which the first day of play was nine-handed, the second day six-handed, and the rest of the tournament heads-up. This effectively made it a hybrid freezeout–shootout tournament, with freezeout play at larger tables and shootout play in the heads-up phase.
