Bally’s Embryon, released in 1981 and designed by Claude Fernandez, is a striking sci-fi machine with a couple of genuinely unusual mechanical ideas. It sports four flippers — including a short, timed “Flipsave” flipper tucked in the right outlane for a last-second rescue — and a clever system of messenger balls, two of them guarded by drop targets and two propelled by a shared fifth ball. A two-ball multiball and crisp speech round out a table that feels ambitious for its era.

The scoring rewards a player who learns its key shots over chasing the multiball, which veterans note is difficult to reach and doesn’t award anything special. The far more productive strategy centers on the saucers and spinner: on most examples you can backhand the right saucer straight from a trap, making it a reliable repeat shot from either flipper, while from the right flipper the spinner is your bread and butter. The 1 and 2 top lanes increase your bonus multiplier, and there’s a useful “hold bonus” at 20K and 40K, with the upper-right rollovers advancing the bonus when lit.

Distinctive, a touch quirky, and rewarding to a player who figures out its logic, Embryon is an underrated early-80s Bally machine with real personality — that Flipsave flipper alone makes it memorable. For collectors who enjoy an inventive layout and a strong sci-fi theme from the dawn of the talking-pinball age, it’s an interesting and satisfying classic worth exploring.
