Slot games, in general, can be divided into online slots with bonus rounds and online slots without bonus rounds.

Slots with bonus games are usually more attractive for players and more fun to play because of the bonus rounds. They’re exciting because you’re always waiting for the bonus round to land and always expecting to win big in the bonus round.

All bonus slots usually have an explanation what the bonus round is about in the game rules. If you want to see what the bonus round is first hand, it’s best to try the games in the free mode first.

How do slots with bonus rounds work?

In order to see what a bonus slot is all about all you need to do is to sign up for an online casino and play the game for free. It’s the same as playing for real money. The only difference is, you don’t have to invest any money. You can read the game rules and the bonus round rules and once you feel comfortable with the game, you can give it a try in the real money mode.

In most video slot games, the bonus round is triggered when three or more scatters or bonus symbols appear on the reels. Once this happens, the bonus round starts and all you can do is to enjoy the privilege and hope to win big.

In general, the bonus rounds are divided into free spins and cash pick bonuses. The free spins bonus is a rewarding round where a player gets a certain number of free bonus games. There are also some other features like multipliers, extra wilds or expanding wilds. The cash pick bonus game usually awards cash prizes for every pick on the reels.

How to win big in the bonus games

One of the most fun features in the online slot machines is the bonus rounds. You get to view secret graphics and gameplay and you are usually given a chance to multiply your potential winnings.

However, did you know that there is a strategy for making the most of these opportunities?

If you don’t believe us, just check out the following…

1. Know your slot

Become familiar with your game and get an approximate feel for how often the bonus round appears. That way you can gauge if the game is being generous or stingy with bonus round appearances when you’re in the midst of playing it. If it’s not giving out too many, it may be time to move to a different slot as the first step to making the most of bonus rounds is actually getting to play them.

2. Use a bonus round hunting strategy

Many professional gamblers sight ‘bonus hunting’ as their chosen strategy when playing online. The beauty of this strategy is its simplicity; play a game until you get a bonus round, win and then leave.

The theory behind this is that you’re leaving every game after getting a reasonable win and each one of those wins add up to increase your overall bankroll, thus giving you more money to hunt more bonuses.

3. Play every line

Of course, it makes sense that you should try to maximise your chances of getting into these bonus rounds. One simple way to do that is to play every line. There are games that only offer bonus rounds to those who max bet, so if your budget is low, give the penny slots a lash and you never know, you might be playing with a bigger bankroll before you know it!

Best Online Slots with Bonus Rounds

There are a lot of great free casino slot games with bonus rounds which have amazing rewards. On some video slot games, the bonus round is incredibly hard to trigger. Still, once this happens the payouts are usually big. These are high variance slots which can pay big in the free spins bonus regime.

Microgaming has a lot of great bonus slots on their offer. Thunderstruck II and Immortal Romance share an almost identical free spins bonus. Once you enter the chamber of free spins you can unlock four different features and choose among different free spins modes.

NetEnt also has a big number of slot machines with bonus rounds. Their most popular video slot game Dead or Alive has a free spins bonus with a sticky wilds feature. Once 5 Wilds land on the reels, the player gets 5 extra free bonus slot games. Win a wild line and the payouts can be well worth the try.

What slot machines have the best bonuses?

The great thing for players is that there are a huge number of slots with fantastic bonuses. We couldn’t possibly list them all, but here are a few examples of some amazing bonus rounds. NetEnt’s Dead or Alive has one of the most lucrative with proven wins of 100,000x the stake up for grabs.

Razor Shark from Push Gaming has another amazing bonus round stacked with free spins and multipliers that is capable of hitting 50,000x the stake when things go well.

Finally, Lil Devil from Big Time Gaming has an exhilarating Heartstopper Free Spins bonus round that is also capable of wins up to 50,000x the bet. Check the reviews here to find plenty more great bonuses.

What are the luckiest slot machines?

Some players may view this as a good or bad thing, but there is no such thing as lucky or unlucky slots. Modern, regulated slots are driven by unemotional Random Number Generators. These math models are completely fair, random and unpredictable.

It is possible to have runs of wins or loses, but this does not make a slot lucky or unlucky. Some slots have paid out more than others, such as Mega Moolah. But this is due to their bonus system, and the algorithms that govern play. Never luck.

What are branded slots?

Branded slots are slot games that use some type of famous element in their theme. This could be anything from movies, TV shows, video games, board games, cartoons, bands, and more. Branded slots are popular because they are instantly recognisable and relatable.

When it comes to bonuses, wins, and gameplay, it doesn’t mean they are necessarily better than non-branded slots. But there are some cracking good examples of branded slots all the same.

Are slots random?

Modern slots offered by licensed providers are completely random. Developers power their products using Random Number Generators that ensure that every spin is completely unaffected by the spins that preceded it. For extra peace of mind, online slots and providers are tested by third-party auditors as part of licensing requirements. This ensures that slots are totally fair and random.

Which slot machines have the highest RTP?

When it comes to RTP, 96% has become the unofficial industry average. Anything above that is considered good. Anything under that not so good – depending on how much less of course. The great thing for players is that there are loads of slots that score higher than 96%.

Some excellent examples that were released quite recently include Jackpot 6000 (98.9%), and Mega Joker (99%) both from NetEnt. Another generous slot is 1429 Uncharted Seas (98.6%) from Thunderkick and Retro Reels Extreme Heat (97.5%) from Microgaming. RTP is always a critical stat we look at when reviewing slots.

Do casinos manipulate slot machines?

Regulated, legitimate casinos do not manipulate slot machines. Slots machines have a house edge built-in, so there is no need for anyone to manipulate them. Regulated casinos have slots tested by independent auditors to prove that their slots produce the results they state.

If a casino was accused and found guilty of manipulating slots they could go out of business. It is just not in their interest to manipulate their slot machines.

Should you max bet on a slot machine?

You should only max bet on slot machines if it suits your bankroll limit and betting style. In the past, some slots would only trigger jackpots or bonus features on max bet. Nowadays, this is virtually non-existent.

Free Online Casino Slots With Bonus Rounds

Now, bet levels of any size have the same chances of launching bonus rounds, free spins, and jackpots. This also includes hitting progressive jackpots. Of course, you should always read the paytable of any new slot to make sure you are clear on the rules.
