Throughout each section of the site we like to have our input on what we think are the best slots and suggest some games for you to try out. So the best free online slots with bonus rounds presented us with quite a challenge, but one that we were ready to accept. Check out our list below and give them a try.

  • Dead or Alive - It just seemed right to include NetEnt Gaming's Dead or Alive slot in our must play list. The bonus round can be very exciting and pay huge multiples of your stake, and what was the final decider for us to add into our suggestions was that as a general rule of thumb it bonuses relatively quickly. 
  • Lucky Lady's Charm Deluxe - One of the biggest and most popular slots to grace a casino floor in Europe over the last 15 years is Novomatic's Lucky Lady's Charm. The bonus round on this game not only includes a catchy tune you'll be whistling for days on end, it also brings excitement with chances of re-triggers and big wins. 
  • Book of Ra Deluxe - Novomatic are also responsible for the fantastic slot that is Book of Ra Deluxe. This again will be familiar to those who have stepped foot into a land based casino in Europe, and from it's huge popularity a whole series of slots have been spawned that go under the name of expanding symbols slots. To see where it all began then give this absolute classic a try.
  • The Sword and the Grail - This game was clearly inspired by NextGen's 300 Shields, but this modern revamp offers excitement and the potential for big wins if you can make it the end of the sword and hit the 100x multiplier. This again is a slot that tends to bonus relatively easy, so you'll get plenty of attempts at trying to reach that multiplier milestone.
  • White Rabbit Megaways™ - Big Time Gaming's White Rabbit Megaways™ was the first slot in the modern era to really showcase the bonus buy option, as well as the unique Feature Drop™ that was created by BTG. With potentially over 200,000 paylines up for grabs during the bonus round, this slot paved the way for a lot of interesting games to be developed. White Rabbit is also one of the most played slots of this site.


  • What is a bonus round on a slot? - Bonus rounds on slot machines tend to be the focal point of the whole game. These features can be triggered through a specific method, or randomly awarded, depending upon which slot you are playing. Entering a bonus round is a players best chance of being rewarded with a substantial multiple of their stake as a prize, as well as being the most entertaining part of the game. 
  • Do all online slots have a bonus round? - Whilst the vast majority of slots that you come across will have a bonus round of some description, there are still a number of games that don't include one at all. Not all players enjoy the flashing lights and razzmatazz of a bonus feature, and a more lo-tech approach is preferred that software developers have duly catered for.
  • Are slot bonuses predetermined? - Whether or not slot bonuses are predetermined is a very debatable topic. What we do know though is that some slots will update your balance before your bonus round has finished, so undeniably the games that do this are 100% predetermined.
