There are 6 arenas within Spartacus Legends:
Extremus (The easiest and lowest paying arena)
Mercatus (A slight difficulty raise from Extremus)
Domis Nobilium (The moderately difficult arena)
Insulae (Difficult but best paying place)
Oscan Capua (Difficult area but mid high fame payout)
Spectacula (Very difficult, but biggest coin/fame payout)[LVL10 Required]
All you have to do is fight in each one, and once you fight for the first time in the last arena (most likely Spectacula), it will pop during the start of the fight
