Design and play
Four Million B.C. is a dinosaur-themed four-player flipper game built around an immediate diagonal ball launch toward the upper-left cliff-hanger shot. The shot requires the player to control the ball's speed and angle across a double incline.
The playfield includes a mystery bonus associated with a captive ball in the Volcano kickout hole, a three-step captive-ball alley called the Tar Pit, left-outlane kickback, a free-ball gate, and the Flipper-Zipper. Bally's contemporary description states that a ball released from the Tar Pit, another released from the Volcano, and the player's shot could place three balls on the field at the same time.
Contemporary release
Cash Box reported on June 19, 1971, that Bally was announcing volume delivery of Four Million B.C. that week. The report also said the game had undergone months of location testing and described Bally's expectation of strong operator demand.
