When the Fish-Fish-Signet combination comes up on the reel unit, the mystery system starts for nine successive plays.
The machine also had a anti-hold after start system to prevent you from constantly turning off and back on the machine after a win until you get the hold feature (and then another win)
The machine usitised a National con rejector, and accepted 6d, 2/-, 2/6 and tokens.
