[1] The system played primarily trivia question games from 8-track tape cartridges.

Each button was also labelled with colors in rainbow order from yellow, to red, to blue, to green, as well as with clusters of letters.

The system heavily leveraged the audio format of the 8-track tape cartridge for gameplay, but additionally included binary encoded data containing information on scoring and the correct answers on non-audible channels, making the OMNI a programmable system.

After inserting a tape and adjusting volume via a slider on top next to the channel selector, each player participating would need to press enter.

Players would then be asked to answer as quickly as possible (indicated by dashes on the display), by selecting the correct colour, number, or spelling out a word and pressing Enter; this would cause the tape to advance forward and reveal the correct answer.
