In our opinion, the best bonus slots are characterised by two factors:
Bonus frequency is important because in most games, it's during the bonus rounds that you'll get the highest payouts. Therefore, the aim should be not to lose all your balance before triggering this bonus round. Nowadays, you can get an idea of the bonus frequency by checking slot reviews or using a tool called Slot Tracker, which provides real-time data about thousands of online slots.
When it comes to additional features, you should choose a slot with a rewarding bonus game so as to compensate for any previous losses. Nowadays, we expect more than just a bunch of free spins on their own. Things to look for in bonus rounds are multipliers (these usually award the slot's maximum payout), sticky symbols, additional high-value symbols on the reels and the possibility of retriggering free spins. And of course, it's also worth going for slots with high RTP to have a higher probability of winning more in the long term.
Slots with bonus games can take a variety of forms nowadays. In this section, we'll look at the most common types you will encounter:
Free slot games with bonus spins are very common nowadays; these work by rewarding you with a set number of in-game free spins if you manage to land on certain symbols. These symbols are called ‘scatters’, and you typically need to land 3 of them in order to trigger the bonus spins. These bonus spins play out at no extra cost, and will have the value of how much you staked on the triggering spin. In other words, if you were staking £1 on each spin and get 10 bonus spins, each of these spins will have a value of £1, meaning that any wins you land on will be multiplied by £1 (i.e. if you land on a winning combination that offers 10x your stake, you get a payout of £10). What's more, during the free spins round it's quite common to get extra features that increase your chances of winning. These features could be anything - low value symbols may transform into higher-value symbols, extra wilds that drop onto the reels, multipliers, or even random cash prizes!
The best free spins slots are those that can be re-triggered (i.e. players can get another set number of spins if they manage to land on certain symbols during the round). You will also find multiple-level free spins, which allow players to progress up multiple free spins levels, each of which will involve better payouts, as well as free spins rounds that give you access to a jackpot.
Another common online slot bonus game is the pick and click bonus. In this case, landing on a certain combination of symbols will transform the reel set into a pick and click game, and you'll see a number of items to pick. Underneath each of these items there may either be a prize or nothing at all - it's all down to luck! Players will be prompted to click on the items to reveal the prize, and normally the bonus game will continue until no prize is revealed, and the players will walk away with the prizes collected up until that point (which could be win multipliers or cash prizes). One example of a pick and click bonus is the coffin game in BloodSuckers slot. In this game, players will keep winning prizes as long as they open a coffin that contains a vampire, but if they pick an empty coffin, the round will come to an end.
A slot bonus game can also take the form of a Wheel of Fortune, such as the one which leads to the jackpot of Mega Moolah and Mega Fortune. This bonus game is very simple - you just have to hope that the arrow lands on a big win or on a jackpot prize!
As slot developers are getting more and more creative with bonus games, these days they may take any form. The bonus game in Hugo 2 slot, for example, involves a Pick and Click Bonus game where players try and help the protagonist Hugo reach a treasure chamber by choosing pedestals for him to cross a deep chasm. Hugo will start the bonus round with a certain number of lives, and will lose a life each time the player picks the wrong pedestal, causing him to fall off. If he gets to the treasure chamber with all 3 lives preserved, players will get a 5x multiplier applied to the treasure chest winnings!
With such a huge selection of online slots today, we don't blame you for finding it difficult to decide which ones to go for. If you're still trying to decide whether or not a slot is worth playing for real money or not, then you should know that you can always play free slot games with bonus features to get an idea of what they involve. Usually, playing a couple of dozen spins for fun could be enough to trigger the bonus round, in which case you'll be able to see whether the bonus is worth playing for.
When you play free slot machine games with bonus rounds, you will be playing with 'fake' coins which you can never withdraw. However, the size and frequency of payouts will be exactly the same as if you were playing the same games with real money, allowing you to get a very good idea of how rewarding the game is. When you hit the bonus round, we suggest observing by how much your coin amount increases, to be able to gauge how rewarding the bonus is. Of course, how much you win from a bonus also depends on your luck, but normally you can always expect to win more than you would during the base game (if the bonus round is any good).
To start playing free slot games with bonus features, we recommend registering with an online casino and browsing its slots collection. Some casinos, like Videoslots, allow you to locate games according to their special features, making it easier to find free slots with bonus rounds. As you can notice from the screenshot below, you can choose to view slots with free spins, slots with bonus games and a number of other features. How convenient is that?!
The below are the most common terms you'll encounter as you read the instructions or help section of a bonus slot game. Some of them have the potential of significantly increasing the payouts, so make sure you take note of them while choosing the best bonus slots to play:
As you can see, we are being spoilt for choice these days when it comes to slot features. Slots with bonus rounds are now commonplace, so the difficult part is not finding such a slot, but actually identifying the ones that are the most rewarding. It's important not to allow a cool-looking bonus round deceive you into thinking that you can really win big. Look at the stats instead, as well as at online slots reviews, or play free slots with bonus rounds yourself to get an idea of how much they pay out. Alternatively, try your luck on one of the top 10 slots with bonus games we recommend above, and keep your fingers crossed!
Online slots with bonus games involve a free round that is triggered by landing on a specific combination of symbols. The bonus game can take the form of free spins, a wheel of fortune, or another kind of game which allows players to accumulate additional payouts without staking anything else for the whole duration of the round.
The best free spins round will involve a good payout potential by including more features or win possibilities than the base game. We also recommend going for online slots with a re-triggerable free spins round, which will allow you to win extend the round with more spins.
You can usually play free slots with bonus games by selecting the demo version at an online casino in the UK. Simply look for your preferred bonus slot game in the casino's game browser and choose to play for fun. You may also be able to play free slots with bonus games and win real money if you get a no deposit free spins bonus.
There are several bonus slots which we recommend for their high paying bonus round. Amongst them, one may mention NetEnt's BloodSuckers, Mega Fortune, Temple of Treasures Megaways by Blueprint Gaming and Big Time Gaming's Who Wants to be a Millionaire Megaways. Click here for a full list.
