A very attractive game. Ballly had a run of machines from 1978-1979 that were all great titles, and operators had confidence in the games Bally were releasing. The theme of the game (Mata Hari was a call girl that was executed for being a spy during WW II), was irrelevant. It looked and played very well. The playfield is symmetrical and lends some of it's design from GTB "Spirit of 76". This game is often remembered for the artwork, and there were plenty onsite during it's time.

All Ballys from 1978-79 were hugely successful.
