After this test play you can continue playing, if you like the game. But don’t forget to read the rules and other useful information, about which we tell you below.


The reason of high number of new slots in the market is a strong competitiveness among online casino providers. It is difficult to make a decision which developer of new slots is the best one. Some of them want to create innovative games with various types of themes with interesting plot and well-made gameplay. Others emphasize and focus all their work on magnificent graphics and true-to-life sounds effects. For choosing a provider of software that you like more you should compare some game of different providers and then decide, which kind of games you want to play more.

Very often a player has also to decide if to play downloaded platform of the casino or directly on browser. It all depends on your internet connection. But nowadays in the epoch of unlimited Internet with 4G covering almost everywhere there is no high necessity of downloaded version. The best UK slots don’t occupy any memory on your phone, because they can be played online in your browser. And of course all of them have mobile version. The most popular software providers are Amaya, Novomatic, Microgamimg, IGT, Realistic Games, Nextgen, Play N Go, NetEnt.

Payment Options

After the choice of game you should make another decision: what payment way you can use for deposits and withdrawals. All we want to have our data protected from any kind of risk. That’s why it’s important to choose right payment way. We can recommend you to use e-wallets such as Paypal or Moneybookers. They will help you to manage your money in online casinos, without given any information about your cards to the casino operator. The most popular and used system is PayPal. But, unfortunately, some online casino operators don’t use this payment method. In this case you can choose other way, like using credit cards, paysafe system, cryptocurrency or mobile payments. But before making deposits control casino’s safety: if it’s licenced or not.

Graphics & Gameplay

The variety of slot games is very big. And many games are different. They can be breathtaking, plain and simple or crummy. But nowadays software providers try to create games for all tastes. Mainly they use up-dated HTML5 and some other software that make all games very similar to video games. Each slot has its theme.

Graphics and gameplay are very important. So when you choose a game you must pay attention for it. The game must attract you without any irritation.

A good game is one that interests its players and gives the possibility to win. In a competitive global production and trade environment it’s not a good idea to create some useless slot with minimum costs. All games must be competitive, if their creators want to have a profit of them.


RTP (Return to Player) is the percentage of the money bet that come back to player after some certain number of spins. Usually RTP doesn’t go lower than 94%. If you find some casino with lower RTP, it’s better to find another one. This percentage doesn’t show that you can return only this sum of money; it can be always as lower as higher. For progressive slots RTP isn’t high. Very often such providers as Thunderkick, Netent and Microgaming have better RTP than others providers.

Payout Percentages

It is the percentage of all sum of money deposited by players that is regularly calculated. This percentage will be given to players as winnings. Usually it ranges from 75 to 98 percent. Very often it’s described together with RTP.

Slot Bonuses

Slot bonuses are a great chance to enrich your pockets. Online casino operators create them from time to time. There are lots of loyalty programs, such as Happy hours, weekly bonuses or bonuses for returning ex-players in game. During your game in online slots you can get in-game bonuses. Here are some of them.

Wild Symbols can replace almost all symbols, except scatters. In this way you can create a combination you need. Also, with three wilds you have a possibility to unlock jackpots or bonus rounds.

Scatter Symbols can give you free spins if you have three or more of these symbols.

Multipliers are mostly available in a free spin round. This bonus will multiply your winning in according to its number.

No deposit bonuses can make you rich without spending anything. Only in case of big winning you have to make a deposit for taking your real money.


You can find two kinds of jackpot that are called local and network jackpots. Local jackpot is a sum of money proposed as a main winning by one casino and the winner is chosen among those who play that slot game. That’s why the jackpot for the same slots can differ: all depends on online casino operator.

What about network jackpot, that is also named progressive jackpot. The sum of money is growing thanks to the online casinos’ cooperation. It means that casinos work together and all money deposited by all their players create this desired big jackpot.

The decision where to play depends on you. If you want to have more chances to win it is better to play new online slots with local jackpot.

Slot Volatility

Volatility, another name variance, is very important indicator that can make clear the casino’s policy. Every online slot has volatility. So how does it work? When the volatility is high, slots will pay rare but the winnings will be big. If the volatility is low, the winnings will be regular but small. But don’t forget about multipliers, which can bring you great winnings.

So if you think that the max bet brings you oftener high prize, you are a little bit wrong, because in games with low volatility it’s better to make low bets. At the same time you should always remember that the random number generator is unpredictable and all people have the chance to win.

Progressive Slots vs Regular Slots

As everybody knows that in slot’s world there are progressive slots and regular slots. But what are the differences? And is it important which one I choose for getting my winning? Let’s try to find the answers, describing pros and cons of each of them.

Progressive slots have usually high jackpots and its sum can change from year to year. For jackpot’s growing online casino operator gives lots of bonuses for all players, because more player deposit in slots, more incredible becomes the sum of jackpot and the RTP become higher. All these factors are advantages of progressive slots. Among disadvantage there are average RTP, jackpot’s accessibility mostly for those who make high deposits and the fact that RTP is usually low and grows only when someone gets its jackpot.

Regular slots have RTP = more than 95%. The selection of games with regular slots is bigger and all players can bet on the highest level without any requirements. But jackpots proposed by progressive slots are always bigger than those proposed by regular slots. Even if we sum all little regular winnings offered by regular slots they won’t reach the progressive slots’ jackpots. And mostly regular slots don’t have so many extra gameplay functions as progressive slots.


How can I check the rtp?

RTP can be found on the site of online casino operator, where you play. It can be written in the rules. May be sometimes it’s difficult to find it, but usually all providers don’t hide this information and it’s often shown in lists of the best casinos. If you haven’t found the RTP it’s better to choose another slot for playing.

Which slots guarantee a profit?

There is no casino that can propose you some slots that guarantee prizes with every spin. Such kind of business requires RTP that must be more than 100% and this is unprofitable for casinos, because in these conditions they become declare bankrupt in a few days. But you can find lots of casinos with RTP almost equal 100%.

Which gambling games are the most popular?

Gambling exists all over the world. It unites people and makes their life full of passion. The most popular gambling games are online slots, poker, blackjack, lotteries, baccarat, roulette, bingo, sport betting, craps and fortune’s wheel. All of them can open in front of you very interesting and unpredictable world of gambling, where all people can play and win.
