Play Free Online Slots With Bonus Games

You probably want to try out the best free online slots with bonus games, so we'll tell you exactly how to do that. It is very easy as you can try out most of the games in demo mode. You can do this at a casino online or on the developer's website.

Please note that although you can try out all bonus rounds, you will not receive the winnings because you are working with demo credits. These will never be converted into real credits, but they do offer you a chance to play the games risk-free.

What Are Bonus Games in a Slot Machine?

Bonus rounds or features are mini-games in online slots , which are usually triggered by a combination of symbols (usually three scatter symbols, or a pair or more of other symbols) and these bonuses can also be triggered randomly. The different types of bonus games and features in slots include:

  • Free Spins : you receive a number of free spins against your current stake where you keep all winnings and you can not lose any money during the bonus .
  • Re-spins : you get an extra spin for free against your current bet, often with (wild) symbols held in place.
  • Pick-me : also called a picking bonus; it lets you play an interactive mini-game and win instant prizes by choosing from random theme selections.
  • Instant Profit : Get one instantly
  • Added/extra wilds : new or extra wild symbols can be added to the reels to help you form more winning combinations.
  • Pathway game : Go through a series of mini-games and win bigger prizes as you progress. This bonus is often part of a progressive jackpot game.

What Makes a Good Slots Bonus Game?

Because bonus game slots are among the most popular in the gaming world, the best online casinos will offer a diverse selection of slots with bonus games – often hundreds of them!

So how do you sort through the good ones so as not to waste time with the bad ones? The three main factors to pay attention to are:

  • Hit Frequency : An online slot can have the best bonus game in the world, but if you can only play it once every 50,000 spins it's not very accessible! The best online slots have bonus games that are often triggered.
  • Payout Potential : A slot bonus game may come often, but is of little use if it can only get your prize. The best online slots bonus games and features will multiply your bet by a significant amount.
  • Fun factor : Besides the money, a big reason to go for a bonus game is that online slots have bonus games to make the game more fun. If a bonus game or feature is not exciting or fun to play, it may as well be left out. After all, a boring game is a bad game!

Are Slots Bonus Games Better Than Slots With No Bonus Game?

Some online slots have no bonus games at all. This is often the case for classic slots , which mimic a one-armed bandit and keep things plain and simple. For other slots without bonus rounds and features, it could be because they offer a high chance of winning without a bonus.

We personally feel that bonus games increase the excitement of playing slots and often bonus rounds also offer a chance to hit the jackpot. So it's no surprise that many of the world's most popular online slots have one or more bonus games or bonus features.

Choose The Top Slots Bonus Games

The easiest way to choose the best slots with bonus is to read our online slots reviews, compiled by our team of slots professionals! It can be difficult at first to choose the best game for you, partly due to abundance, and partly due to personal preference. Our reviews will give you the honest and critical information you need to choose the game that meets your requirements.

Our slot review process includes analyzing the features, symbols, paylines, jackpot, mobile compatibility, software and bonus rounds. We also look for the best bonuses in downloadable and non-downloadable games.

You can even play bonus free slots to get a feel for the game before playing for real money. We have a large collection of new online casinos in our top list that offer free slots and free casino games with bonuses to try with no registration and no deposits .

Don't waste time sifting through hundreds of slots to find the best - just use our top list of the best online casinos and our expert casino and slots reviews to jump right into the action and spin your way to instant winnings. And don't worry, new slots are coming out all the time, but we always keep our recommendations up to date.

How We Rate Slots Bonus Games?

In any case, we only recommend slots from reputable providers. That is to say that they are licensed by a reliable authority such as the Maltese casino anyway. In addition, the games must also be tested for randomness by an independent party such as eCOGRA. We also use the following criteria, among others:

  • Good Graphics Quality : A game is just more fun if it is designed so well that it looks like a movie.
  • Great Prizes : As we said, slots with bonus rounds have to offer prizes that are worthwhile.
  • Fun Theme : Nothing is more annoying than wasting your time with a boring slot machine. The theme should not only be well put together, but also appeal to different players.
