The 4-player version of this game is Williams' 1973 'OXO'. The available manufacturer's documentation for this game in our Files section is dated from Oct-31-1973 to Dec-13-1973. According to Williams Daily Production Logs, funding was approved for a quantity of 98 sample units to be made of this 2-player version. It first appeared on the Production Log dated Oct-3-1973 and last appeared on the Log dated Dec-14-1973, showing none produced. We don't know why it did not go into production. Curiously, on the following day's Log, it was replaced with a proposed 98 sample units of Williams' 1974 'Super-Flite', also a 2-player and which did proceed into production. Perhaps that is a coincidence, but we might have assumed that this was evidence of a simple rename of the project if it were not for the actual game pictured in this listing with a theme more befitting of the name 'Triple X' than an aircraft theme. We are aware of only the example pictured here, likely a prototype. Reportedly, it has no serial number and has poor quality soldering, not assembly-line quality. We don't know when it was made in relation to its appearance on the Daily Production Logs.
