'Triple Action' was the first Genco machine produced with flippers. According to Steve Kordek, this was the first pinball machine to have only two flippers, placed at the bottom of the playfield. An earlier game, Genco's 1947 'Bubbles' was not placed into full production and may have had flippers. For more information, see that listing.
