Sparta takes place on 5 reels with a total of 25 pay lines on which to bet, with bets starting at 0.01 coins per line. Free games are triggered whenever at least three ballistae appear in the field of play. At the beginning of these games, six shields appear, from which you select three shields, each of which contains up to seven free turns. During free games, all prizes are multiplied by three and the feature cannot be retriggered during free games.
This game also has a progressive jackpot that accumulates over time and can be triggered at the end of any round of play. Sparta also has an auto play feature in which you direct the game to make up to 500 turns in your place so you can sit back and watch the action unfold.
