Bonus rounds can take various forms, such as free spins, mini-games and gambling/risk options, to name a few. They are usually triggered by the appearance of bonus symbols, and as with combinations of winning symbols, are set to appear to players completely at random, unless unlocked by achieving certain game-specific goals. Here at Casino.org we’ve tested, reviewed and compiled a list of the online slots offering the best bonus rounds.
Because the symbols have an equal chance of making an appearance on the wagering line. The very early slots could be examined to check the chances of a single combination of symbols being hit. What a person needed to do in order to check the chances was to count the total amount of symbols that were on a reel to ascertain what was what and then go from there. As an example, if a slot machine did have three reels, which came with fifteen different symbols on them. It means it has 3375 possible different combinations to it, which translates to 15X15X15, and creates a 1 in 375 chance of ever hitting a jackpot on this slot machine.
Every casino will have a ‘Max Bet Rule’ which will come into play when you have an active bonus. Every time you accept a bonus you should always check how much the maximum bet is at the casino you’re playing in. Every casino is different so yes you will need to check every time. It may take a few moments to check it but it could detrimental to your winnings in the long run.
With literally thousands of real money slots out there, choosing which one to play is bound to get confusing. On top of this, brand-new slots are constantly being launched every day. Their aggressive marketing strategy further adds to the difficulty of making a choice. Although previously players opted for games with higher RTP, it is no longer that simple to pick out your favourite casino slots. High-quality graphics and gameplay also make slots games more attractive. To top it off many real money casinos are using slots to target new players by tying in welcome bonuses such as first deposit bonuses. Thus the dilemma many slot players are faced with.
The most popular type out there, video slots have taken over casino games online. There are literally thousands of options to choose from and they vary in terms of their in-game features as well as RTP rate and bonus rounds. Paylines can be anywhere up to 50 and you can expect some big wins with these. They are particularly common with new players looking for good 1st deposit bonuses to claim. Thunderkick's Flame Buster is just one of the many options out there and Videoslots is just one of the online casinos which offer sign-up spins on the game. One thing to note is that most online casino bonuses won't accept deposits using e-wallets such as Neteller and Skrill.
Blackjack is another world famous casino game: born in France, called BlackJack in the US, the player here plays against the dealer, initially both player and dealer receive 2 cards with the goal of reaching 21 the players wins when making a higher points count. Originally if the player was making Blackjack with an ace and a jack of spades the winning used to play a multiple of 10 times the bet, this bonus is no longer in used in casinos. There are lots of movies inspired to blackjack and to its strategies, if you wish to know more about when you have higher chances to succeed on a double down, or when to “split” or when you should put an “insurance” on your bet, check out our News section, you will find lots of helpful articles that will guide you and suggestion what you should do based on your cards and the dealers.
Another system from that same book is called the “play and run” system. The idea behind this system is that you don’t spend more than 5 or 10 minutes at each slot machine game, then you run off with your winnings. Patrick suggests that you divide your bankroll into 5 or 10 sessions of 5 or 10 minutes each. Like all of his systems, you quit on any machine when you hit 9 naked pulls.
One of the points we hammer away at is the safe play. One of the ways to play safe is to use online casino sites that are high quality. It’s very easy to set up a quick site to scam a few vulnerable or incautious people (we’re also a king site that doesn’t call the victims of crime “idiots”), but to deliver a site that actually works and delivers good experiences and good information takes effort. And we put in that effort! Our online slots reviews are well-written, honest, and nicely laid out – plus all those good things we’ve listed above. We’re top notch – even if we do say so ourselves!
There’s no need to list all the benefits of the free online slots machine games – just take one peek at the reviews and demos, they speak for themselves. Nowadays they’ve gone a long way from those cheesy and clunky “grandma” fruit machines, which used to sit in the dusty gaming parlours. Now you get an extremely modern experience, which pleases the eye and tickles your senses without much effort from your part. Check out the vast array of themes, which are offered by the rival manufacturers – your mind will be blown by the sheer amount of choice, and new video slots machines just keep on coming out every day! And about that “video” part – it’s true, you don’t just get a jerky “spin” animation, far from it. The movements on the screen are so fluid, you’ll be entranced in seconds – it’s like watching a movie!
Alternatively, you can browse for games based on different criteria. You can find games by choosing a filter such as a software provider, paylines, reels, bonus game, progressive. As new are released, we’ll be adding them to this menu making sure you get your chance to review and have a go on the latest games for free, before you go off to play for real money at a casino you like.
As technology improved slot sites moved away from much-loved classic games to offer new features through the launch of 5-reel slots. Obviously, the increase in reels increases the house edge but it also leads to higher payouts. They are a popular type of online slot machines as they provide a good trade-off on payout percentage. Obviously, added complexity has lead to unique features. Multiplier symbols, wild symbols and bonus games are a few examples. Barcrest's Rainbow Riches is a good example of this type of slot and many online casinos like Casumo will even offer no deposit free spins on this as part of their welcome bonus.

There are many online casinos to choose from, and sometimes players might become a little overwhelmed. We wouldn’t recommend Café Casino as our top casino if we weren’t sure that it was the best place for gambling. All of our 90+ casino reviews are based on a number of important casino comparison criteria to help you get a feel for each casino’s gameplay and experience. Alongside the security of a site for protecting players’ data and offering a fair game, this includes things like:
Balance. Prizes or lost credits are instantly summed up after each spin in the balance box of the specific game screen. This box is normally clearly displayed in the bottom left-hand corner of the slot machine. Be advised that the balance showed will change when the “Real Play” for actual cash is initiated. The credits usually renew to its free credits balance automatically; whereas the “Play for Real” option must be downloaded with funds prior to betting with actual money.
Up until a few years ago, Playtech was synonymously known for its Marvel Avengers Slots online.  They even had some progressive jackpots and with so many people trying their luck, the prize pool was sky high. Their Marvel themed progressive slots were one of the best ways to win real money. Unfortunately, this all changed when Disney withdrew their rights to use the characters. Today, Age of the Gods has taken their place. Again some of their options come with some great progressive jackpots.
Detailed gameplay is offered, but the risk is still yours to take and understand because you may be wagering pounds or Canadian and Australian dollars. However, the best advice from longtime gamblers is to understand that strategy guides offer “unofficial” techniques and basics about online slot machines, slot betting and how to understand pay tables and pay lines. In general, online gambling and free slot games online are similar to betting in a casino or betting parlor.

There is one very important implication of this: if you are losing too much while playing a game from a reputable game provider, you can be quite sure that it’s just your bad luck. Even if you play your favorite game at an unknown casino, you are quite safe, in terms of game fairness (though you may be not safe in terms of actually getting your money – use our casino reviews to find a reputable casino that actually pays the money out, even when you win big). I’ve had gaming sessions with an RTP below 50% in the past.

The possible combinations of icons on the reel are astronomical and they are highly randomized. Only a detailed study can help you check if the house is slacking on their random number generator. If you don't have the time, resources, and guts to log slot machine results, then stick to scheming for bonuses instead. Slots with many reels have higher chances of awarding bonuses. Impressive first deposits also attract bonuses. To enjoy free slots most, use winnings from other games or loyalty points from friends. These days slots are developed factoring in consumer psychology, so the reels seem to behave like the jackpot has been hit. That being said, if you become very familiar with slots that have few reels and are only moderately popular, there is a possibility you'll learn to predict their results.
This reminds me that I should explain how RNGs work. Modern RNGs used in online casinos are dedicated hardware devices that generate random numbers out of electromagnetic noise. It’s like an old television without signal – a lot of black and white dots. Black pixel is 0, white pixel is 1. Take a photo of a small part of a TV screen, convert the pixels into 1s and 0s, write them into a text file and you have a random number.
The moment that you hit all of the necessary special symbols on a video slot game, you will notice that the bonus feature starts automatically, and you will need to follow the instructions on the screen to play and stand the chance of winning big. The bonus rounds can be a whole lot of fun and they are actually one of the main reasons why video slots have risen in popularity throughout the years.
However, before we continue with more online slots tips we should make it clear that you can win or lose on any slot game regardless of its RTP. Even a game with a 98% RTP doesn’t guarantee that you are going to win, and these percentages are based over a long period of time rather that just one playing session. Play a mixture of games, with different RTPs and you’ll soon discover the best slot machines to win based on your own personal preferences.
Six and Seven Reels. These get a little more complicated than the aforementioned three and five reel video slots. As an example, we will use a standard six reel favourite that is widely prevalent online – Zeus III. There are six reels, and each reel has two rows. They increase by two all the way up to the sixth. Thus, reel one has two rows and reel six has seven – which combined, provides the gamer with 192 possible ways to win.
Bonus Rounds. This consists of shooting or revealing predetermined hidden objects. Gamblers like these distinguishing characteristics; because once they trigger them, it is basically guaranteed that they will land on a decent reward without wasting any funds. These particularities can also include Retriggering: Launching another free “Bonus Round” or “Free Spin” when earned again while the bonus is enacted. And the Spinning Prize Wheel: This uses the old prize wheel to win several differing amounts from small to large. The player spins the wheel and hopes that they land on the top prize shown.
Firstly they are all fully licensed and monitored by third parties to ensure they abide by all requirements. You'll also find that they have slots machines from some of the biggest giants in the industry. This is further assurance as being so successful they must ensure that their name is kept in the clear. All of their games are RNG tested and they are regularly audited by independent authorities such as eCOGRA and iTech Labs.
The affiliate marketing model used by the majority of the online gaming industry has shaped the way casinos rise to the top or fall to the bottom. Whereas some affiliates choose casinos based solely on projected profits, most use casinos’ histories to some extent to determine whether they are a trustworthy establishment to advertise. Affiliates are also the primary source of mediation for players who are facing issues with a casino.
