The Coliseum symbol is what earns players their free spins. Matching three or more of these on both sets of reels will give you free spins and a bonus multiplier for those spins. The Spartacus symbol serves as the wild symbol for this particular game, substituting any other symbols required for a win. As an added bonus, the wild symbols can stack and therefore you could match a full reel or near-full reel of wild symbols to win a jackpot amount.
