In online slot games, bonus rounds are unlocked through certain symbols or in a specific type of event. Each of them is an opportunity for players to take a break from the mechanically normal rounds and try their luck with unique challenges, multiplied spins, or instant-win rewards that can boost winnings far beyond what one pickup round could bear.
Types of Bonus Rounds
Different bonus rounds consist of:
- Free Spins: Play Now Another fantastic feature of the Hitman slot is its Free Spins.
- Pick-and-Win: Players can select from a series of items to reveal instant prizes, multipliers, or another type of reward.
