Triple X

Triple X is a rare Williams prototype from 1973, designed by Norm Clark with artwork by Christian Marche, built around a Tic-Tac-Toe theme with a lit matrix set into the center of the playfield. Funding was approved for 98 sample units - the project first appeared on Williams' Daily Production Log on October 3, 1973 - but the log shows none were ever actually built, and the entry was dropped by mid-December 1973 with no explanation on record. The very next day, funding was approved instead for a 2-player prototype of what became Williams' 1974 'Super-Flite,' though whether that was coincidence or a renamed continuation of this project is unknown.

Only a single example of Triple X is known to exist, and it appears to be a genuine prototype: it has no serial number and shows soldering of non-assembly-line quality. A related 4-player version of the same tic-tac-toe concept, Williams' 1973 'OXO,' did reach production.

Gameplay-wise, the machine features two flippers, three pop bumpers, two slingshots, three standup targets, two kick-out holes, and an end-of-ball bonus. Its most distinctive element is the illuminated tic-tac-toe matrix at the center of the playfield. Because it never left the prototype stage, Triple X remains one of the rarest items in Williams' history - a genuine one-of-a-kind curiosity for collectors.
