Types of Online Slots

Fruit Machines
Online fruit machines are inspired by old-school one-armed bandits. Their distinctive features are a plain gameplay, the only payline and 3 or (rarely) 5 reels. The gaming symbols include pictures of fruits and berries, as well as bars and sevens. Fruit machines look a sort of simplistic and are easy to play, but some of them bring very good winnings. Fruit machines are produced by most software developers.
Mobile Slots
The slot games optimized for the screens of mobile phones and tablets are commonly referred to as mobile slots. They have exactly the same features, rules, bonuses, etc. as their desktop analogs. Their main distinctive feature is their compatibility with a touchscreen, which means that they are controlled via gestures and touches. Mobile slots are usually available via a dedicated app.
Progressive Slots
Progressive slots are the slot games connected to a progressive jackpot. With every spin, a small fraction from every player’s stake is deducted and added to a common “pot”. This pot’s size gradually increases until somebody is lucky to get a special winning combination and hit jackpot. The amount of progressive jackpot can reach several millions of dollars.
3D Slots
The main selling point of 3D slots is visual effects. A 3D slot can have a standard set of features, but the use of three-dimensional graphic makes it look more impressive if compared to usual video slots. That said, they are more resource-intensive and optimized for desktop PCs and not for mobile devices.
Video Slots
Video slots are, probably, the most popular category. Classic video slots have 5 reels and 20-25 paylines, but today one can find options with 50, 75, and even 100 lines – the diversity of these games is impressive. Video slots are often “themed”, i.e. dedicated to one particular theme. For example, some of them are inspired by movies, games, movies, etc.

Tips to Win Online

The first thing you need to know about slot games is the fact that they relate to so-called games of chance. It means that nobody can calculate the probability of winning or losing. The game outcome is absolutely unpredictable and depends on your luck alone. That is why there can’t be any winning strategies: they simply don’t exist. And still, there are some ways of optimizing the gaming process and reducing the losses in the long-term perspective. Here are some general tips for gamblers.

  1. Check the RTP indicator of a game. The higher the return to player is, the more money invested I playing this game are returned to players. Try to choose machines with the RTP of 95% and higher. Of course, the figure 95% doesn’t mean that you will receive strictly 95% of your total investments, especially in the short-term perspective, but in the long-term perspective, the result will be close to this indicator.
  2. Chose non-progressive slots. Playing progressive slots, you’ll have to always bet max in order to get a chance for hitting a jackpot. Moreover, you’ll lose a certain percentage from every spin. Finally, the major jackpots are won relatively rarely, and the number of players worldwide is enormous. In non-progressive slots, the jackpot size is less impressive, but the probability of winning is much higher. If you are not ready to invest in gambling heavily, opt for simpler games.
  3. Don’t spend more than you can afford on gaming and never wait for on a positive outcome and never lend money for playing! All the casino machines are constructed in such a way that a player loses its money in the long-term perspective. Occasionally, players win more than they have lost, but it is the exception rather than the norm. Allocate the sum of money you are ready to lose and play with this money. And let the winning be a pleasant surprise.
  4. Enjoy it! Gaming is an entertainment, not a method of making money. So take it easy: play the games you like, enjoy the gameplay, and don’t be upset when you lose. Your fortune can smile to you at any moment. It is important to choose the games that you like, not those that (as you believe) bring you high winnings.

Online Casino Bonus

Bonuses are an integral part of gambling. No matter whether you are planning to play slots for fun or take part in real-money gaming, you can take advantage of special bonus offers of casino sites. All new players are eligible for one bonus or another. There exist different types of bonuses: we’ll tell you about the most popular ones.

  •    A deposit bonus is provided to anyone who made at least one real deposit. It is usually expressed as a percentage from the deposit. For example, if the deposit bonus is 100%, you’ll get $100 as award after you deposit $100. Sometimes, the bonus size can reach 200-300%.
  •    A no deposit bonus is credited to a player’s account for a mere fact of registration. It is usually not large – somewhat $5-20 or 20-50 free spins. Some casinos allow using the no deposit bonus for playing any games, while others – only in certain bonus slots.
  •    A no registration bonus usually comes in the form of free virtual credits that can be used for playing free slots no deposit. But one needs to understand that this is not real money, i.e. you can’t withdraw it from a casino. These are virtual coins that are used only for playing the particular slot. To get real-money bonuses you need to create an account, at the very least.

Every time before claiming a bonus, check the terms and condition info, in particular, the wagering requirements. Keep in mind that you won’t be able to cash out the bonus funds immediately. You need to fulfill the wagering (playthrough) requirements first. It means that you need to make bets totaling the amount of the bonus multiplied on the wagering requirement. Thus, if the bonus is $100, and the WR is 60x, you’ll have to place bets totaling $6000. After that, you’ll be able to cash out the bonus and the winnings.
