Deposit Bonus Offers

Deposit bonuses are a cornerstone of the online casino industry. While there are many good reasons to play casino games online, there are few more attractive ones than the deposit bonuses issued by the top online casinos.

Deposit bonuses are issued upon depositing money into your account and they can make a short bankroll last a lot longer. Unlike brick and mortar casinos that so often don’t award players in any meaningful way, online casinos will give you a bonus on most deposits you make, greatly increasing the chances of winning cold hard cash.

Wagering Requirements Explained

Deposit bonuses may seem too good to be true and you might think that there is a catch. The real truth is that online casinos do want you to play with the bonus money, which means you won’t be able to make a cashout at any time, but this does not mean the bonuses are not worth taking on.

Every bonus you receive will have some wagering requirements attached. These requirements will make you wager your bonus money a certain number of times before you can cashouts the winnings. Usually, top casinos only apply a wagering requirement of about 30x your bonus, which is by no means excessive. In fact, a bit of good run will see you clear your bonus money in no time.

Is It Legal to Play Slots Online?

Online slots and online casinos are fully legal, with all the big brands applying for licensing with international regulatory bodies like the Malta Gaming Authority, UK Gambling Commission and the Curacao eGaming. However, some countries don’t allow online casinos to operate in their jurisdictions.

The biggest example is the USA, where it is not legal for online casinos to operate within borders. Some international casinos still take American players and as a player you will not have legal problems if you play at these casinos.

Countries like Australia and Canada allow online slots with many online casinos accepting players and all online play being fully legal. If you are going to play online slots from the UK, you will want to do so at a casino that operates under the UKGC license for your own safety, even though no legal penalties can be issued for those who decide to play at other casinos.

Return to Player Explained

All casino games are programmed to give the house a small edge. This edge can range from anywhere between 0.5% to 20% or higher, depending on the game you choose. The top online video slots feature a return to player of about 96% to 98% making them nearly break even propositions in the long run.

The return to player (RTP) number attached to every game you play online is the amount of money that is paid back by the game in the long run to the players. A game with an RTP of 97% will pay back 97 cents on every dollar players wager on it.

You will want to look for slots with high RTPs in order to minimize your losses and give yourself the best possible chance at big winnings.

Top Slots with RTP of 97% and Higher

Mobile Slots – App or Browser?

Mobile gaming is becoming ever more popular. The mobile casinos are now giving players an option between playing in their browsers or downloading an app to play in. While some casinos still offer mobile apps, most of the big name casinos rely on their mobile websites to do the trick.

The easiest way to play mobile slots is to sign up with a site like Videoslots or SlotsMillion that allow players to play all their slots in the mobile browser. Simply sign up for an account and start playing without waiting for downloads, cluttering up your phone or filling up your precious storage space.

What are online Slots?

In the past, online casinos were only accessible to dedicated players who have ample cash on hand to pay for their slots. However, as the amount of competition has grown, casino operators have begun to accept players who are merely seeking a quick fun bet.

Nowadays, several online casinos are open for players without any immediate source of income. In fact, many major online casinos such as the and Betsoft, are registered with the German gambling regulator. Therefore, unlike the traditional casinos, players do not need to have an in-person account to place a bet with these online slots.

Similarly to traditional slots, some online slots employ hidden cards to give players an edge. Another popular type of online slots is based on digital technology. These kinds of slots are commonly used for promotions, giveaways, and seasonal themes. Moreover, you can find online slots in virtually any language.

Slots with a wide range of options

With the wide range of slots available on the market today, many players cannot wait to try out all the different types. When choosing the type of slots you like to play, you can consider the type of games that you enjoy playing most and the length of time you like to bet on a game.

If you’re a newer player who is still learning the ropes, then you should go for the simpler, more simple slots. They will be able to fit into your normal gaming routine. While it will be more time consuming to earn the initial profit, it will be easier for you to achieve a stable income.

If you have experience playing slots for years, you can go for the more complex games. These will require more strategy on your part and might take you longer to win. Nonetheless, the higher profits from these games will be worth the time you invest in them.

Slot machines offer the most exciting variation of the traditional pay-to-win model in video games. The players do not have to spend anything to start playing, but they can make real money if they win. That money can be used to buy chips with real money or used to get new skins, emotes, and badges in the game. For example, at the time of writing, the most recent “Risk: Giants” event offered a skin and badge for 5,000 “stake tokens” as well as a special emote to represent the money. On top of that, people who want to have an advantage and have a lot of money can buy the title and access all the chances to win.

Why do players feel cheated?

The problem is that this kind of cheating usually causes no game-over penalty, even if you get big money. This effectively means that the person has won before the end of the game, and they can keep playing. The player might feel cheated, but in fact, he or she is really enjoying the game and this is not how he or she wants to end it.

What is really needed is regulation to prevent this kind of problem. Online gambling is legal in a lot of countries, and even if we look at countries where it is not legal, many casinos and websites are offered by the big operators. They simply enforce their own rules. For example, some casinos require people to pay a fee to get a level up.

After someone has bought some more coins, he or she is no longer able to buy more “stake”, and he or she has to buy a ticket. Even if this ticket is just to gain access to the casino for a while, people still consider it as an advantage.

Another type of cheating can be imposed by bots. Sometimes people use this in casino websites. While there is no direct relation to the real-money systems, there is a direct relation to the random number generators and time limitations.

Are online slots safe?

Once you start playing online slots you have to be aware of the fact that no online casino is completely safe. Nevertheless, there are lots of online casinos that guarantee a secure gaming experience. This means that you must be careful to do no deposit on any casino, as this will only give them the opportunity to collect all your information to later use against you. So don’t do that!

Online casino security software can be very helpful. The actual software itself will detect malicious software, protecting your deposit and withdrawals against problems.

Online casino security

The best way to keep all the information you need safe is by installing the security software on your computer and using it every time you log in. You also have the option of installing your own protection on your web browser, for example an extension of any of the top web browsers.

You can use online safe security software like Avira to protect your online activity. In addition, you can always use a separate browser, dedicated to that specific purpose. This is a real hassle if you use many different online casino games. So why not just install an online browser specifically designed for this purpose?

This type of software can be very useful when it comes to preventing your own bank account from getting hacked. You will be able to do a lot of things like report suspicious accounts, block accounts and so on.

It is important to make sure that you avoid creating accounts under false names. This will increase your protection and keep your account safe. However, you also have the option of using something like Prox, which can add extra protection for mobile app transactions.

How to play online slots?

There are many online casino sites that offer slot games, as online slots are among the most popular online games. As you will find out in the following paragraphs, you will be able to enjoy a great variety of online slot games. However, to really enjoy online slots, you need to be familiar with them. So, read carefully what are the rules of each online slot game.

In general, online slot machines feature 3 rows of 3 virtual symbols, which are called reels. A play, which is made on a reels, will result in the symbols at the end of the row being revealed. At any given time, 2 of the 3 reels are turned, thus displaying two symbols for each. One of the symbols will contain the wild symbol, meaning that if the reels are turned, the chance of winning a jackpot increases. The other symbol will be a reels spin, meaning that it is the play with the lowest probability of winning a jackpot. A reels spin will change the outcome of the game, meaning that it is the wild symbol that the player will try to influence.

Online slot machines feature a jackpot symbol at the end of the third row. In case a player does not have enough money to start a play, they can bet on the jackpot symbol. In the case that the jackpot symbol is won, the winnings will be sent to the player’s account. There are 2 different jackpot symbols, meaning that there will always be 2 different jackpot symbols in the online slot machines. However, the effect of the jackpot symbol can only be determined in case the winnings are actually sent to the player’s account.

Note that the payback period of online slots is the maximum duration of a slot game. It is usually 3 or 5 years. In case the player wins a jackpot, this payback period will be increased, however, this will reduce the player’s chances of winning a jackpot for a long time.

Of course, you must be aware that there are some exceptions to the rules of online slot games. Such as the skill element of online slot machines. In such cases, the play is controlled by a computer. If the player does not make a choice on a slot machine, they will be automatically called the winner. The bonuses from online slot games are usually a different feature. These bonuses are awarded for a particular action or situation, with varying payouts.

Are there slots that can be played?

There are a few types of slots that you can find in the online casino sites that offer them. Among them, there are spinners, progressive and action slots. In general, spinners slots feature animated symbols, often with an impressive 3D display. In such cases, a spin will appear at the end of a reels, with all the symbols turning into a star. This means that the play with the highest payback period is the one with the highest chances of winning a jackpot. On the other hand, progressive slots features additional symbols, each of which have a chance of winning a jackpot.

Action slots features symbols which move around randomly. They have high payback periods and usually have a short delay between a reels and a spin.

How to find the best online slots for beginners?

It is always best to stick to online casino sites that have both established reputation and established popularity. A casino that is relatively new will lack the reputation and the experience of a casino that has been around for a long time.

On the other hand, you will probably not want to pay for expensive and inexperienced slots games. Therefore, you will probably want to keep your visit to casinos under control and only visit websites that are recommended and reliable. In case you do not want to play online slots games, you should find something else, such as a game of luck, where you do not need to bet on any symbols and the play will be handled by a computer.

There are many online casino games, and choosing the best one can be hard. A lot depends on your mood and your chosen games, though. The idea is that you do not want to spend a lot of time and effort if you are not familiar with the game. Nevertheless, finding the best online slot for beginners should be one of your priorities. You will definitely want to find a site that is easy to play and on which you can win some extra money. A good idea would be to try online slots games before you make a decision. Even if you do not win a jackpot, you can always make some money and that is enough.

Online Slots are Better Than Online Casino Games

It’s no secret that online casino games will blow you away. Each time you lose at a game, you expect that the next is a sure thing. Online casino games are kind of like this, but at least in this case, you can calculate your chances of winning.

In all reality, your chances of winning are about the same as your chances of winning at one of those roulette or slots machines.

The other interesting fact that some people don’t tell you is that when you pick up your phone or computer to try and play online casino games, your odds of actually winning are always slightly better.

Do you like that better odds? Of course, the online casino games are generally the most basic and you can beat your bookie with an online casino game. As for the randomness, that’s part of the fun.

Avoid High Stakes and Big Winners

Many people know that the biggest factors in winning the money they play for is their skill, luck, and a whole bunch of other things. If you have a skill level close to average, you might not go home empty handed. But, if you have extremely good skill, you’ll usually find yourself on a win streak. Then, the next time you stop playing, your luck runs out.

Even though it sounds fun and exciting to play with large amounts of cash, most of us don’t have the discipline to play poker with millions. Our point is that if you play a casino game that is easy to win and simple to play, you will likely enjoy it much more than you would if you had to spend hours learning the complex rules of roulette or betting at the tables.

Can you play online slots with Bitcoin? Well, I wouldn’t recommend it. You should play online slots with real money instead. To gamble with real money, you need to be playing real-time games, such as land-based casinos, online bingo, or lotteries. Although casinos can use Bitcoin for some services, such as payment processing and online security, you don’t have to use Bitcoin for all the services that you need.
