Free Slot Machines with Bonus Rounds

Imagine the feeling of spinning the reels, winning a prize, and triggering a bonus round. When you play free slot machines with bonus rounds, that's possible. Any spin could lead to an exciting bonus. With that bonus, you stand to win extra cash. The unexpected always feels fantastic.

The bonus rounds in slots differ from game to game. You usually have one of these options:

  • Free spins – These free rounds may have extra wilds, multipliers, or sticky symbols/frozen reels.
  • Interactive pick 'em game – It may be a single level or multiple levels that boost the number of free spins and multipliers you get or reward you with an instant cash prize.
  • Prize wheel – Spin a wheel to win cash, multipliers, or a jackpot prize.
  • Board game – You roll dice or spin a spinner and move spaces collecting cash or other prizes along the way.

To trigger the bonus, the game rules often require a number of symbols to appear on the reels or on a specific line. Some bonuses are triggered randomly. There are also bonus games that only become available if you bet a certain amount on the slot game you've chosen.
