What is your type of slot player?

It is known to play thousands of slot playing and choosing themselves and the agony of choice is yours. However, you should not only pay attention if you like the graphics or you are sympathetic to you, whether the casino, in which you play a bonus or other casino actions, but should you analyze what a slot game type you actually.

In English there are three categories of player types, high rollers, mid rollers and low rollers. In Indian, one would describe the high rollers as more wasteful or risk-taking players and the low rollers as more conservative players. In order to get the most out of your casino bonus, you should choose the slots that suit you.

Low Rollers

If you are a low roller, you play the slots for as long as possible without wagering a lot. You would be advised to use classic slots, such as fruit slots with 3 reels or slots with 5 reels that allow low stakes. You should also stick to machines that only offer small jackpots, because the lower the jackpot value, the easier it is for you to win it and with a small stake. So choose slots with a low volatility or variance. The smaller the coin size you can use, the longer you will be able to play.

Mid Rollers

If you are a Mid scooter type, you actually play because it's fun and but also because you would like to win something. But you probably clearly realize that you can often get smaller profits and can only pluggeast more from time to time. Your budget is clearly slightly bigger than that of a low scooter and you like a little more. You are the rather the type that plans everything exactly and makes clear specifications in itself. You will get the opportunity to get a smaller profit often at mid-volatility, sometimes a smaller profit, then maybe nothing to gain anything and but also from time to time.

High Rollers

If you sign up as a high scooter, you're ready to take high risks and may be more of the wasteful type with a high player budget. You do not mind buying longer thirst trails in which you do not win over numerous spins, even no small profits.

You know that you can be rewarded with lucrative profits for a high and continuous commitment. You are recommended slots with high and best progressive jackpots as this is exactly what you are looking for. Slots with progressive jackpots usually have the highest volatility, so they offer you the highest risk. At the same time, the slots where you can use high coin values are ideal for you. Whether in an online no deposit casino or another, you will take the highest risk and wager a lot of money.

The most popular machine themes

Free slot machine games Games serve to get to know the functions of the game, but also to see the many different topics that are now offered in the slots in the online casino. There is almost no topic here that is not there. The list would be endless and there are really very “other” topics like love, Halloween, luxury, shopping slots for women or whatever you can imagine. Nevertheless, various topics clearly stand out, these are:

Fruit slots

The classics with symbols such as fruits, stars, bells, bar symbols and diamonds.


Probably the most famous Slot Machine is the Book of Ra, which was often copied and varied. The pharaos with their gold treasures and pyramids can be seen on numerous rolls.


Four-leaf clover, goblins and pots of gold are extremely popular in slots like Rainbow Riches or Irish Luck.


Probably the most famous slot machine with animals is the progressive slot Mega Moolah and the cute symbols always bring fun to the screen. There are slots with wild animals, safari themes and also cuddly stuffed animals.

fairy tale

Whether Hansel and Gretel or Jack and the Beanstalk, fairy tale themes are extremely popular in slot machines.


Castle Builder or Game of Thrones are popular variants here and there really are no limits on this topic.


Whether 80's TV hits or brand new action movies, here you will find everything the heart desires from Scarface to Jurassic Park.

Tricks and tips for playing slot machines

There are many myths about the topic of whether it is possible to attract slot machines. The answer is clear: Yes. Of course, the machine game, as well as other casino games, is a clear gambling and happiness ultimately decides how much you can win and how often.

Playing Slots is not least so popular as it hardly needs strategies and do not have to learn many rules, e.g. When playing roulette or poker. The exploitation of Free Slot will help to get scary to get to know the vending machines and know what's for features.

Payout percentages and odds

The payout quotas, also called RTP (Return to Player in English), can be found at almost all slots on the information page. With slots, this is usually between 94 and 97% and that is a good guideline after you can go if you want more profits. A higher quota thus brings more winning opportunities. The online casinos offer with high payouts with high payout rates so that players are always motivated and do not play at others or even change casinos.

Random generator

The machine determines when a profit is paid and how high this is paid out. It does not matter how long you play the slot or how much you use. Of course, the gains are higher at higher missions. However, the moment of winning is random. The casinos are tested by independent companies and thus guarantee a fair game.


Another great tip is to understand the volatility of a slot machine. When a slot machine is highly volatile, the winnings are very high but rarely occur. The risk when playing is clearly higher on such a machine than on one with a lower variance, as the volatility is also called. Especially the high rollers, i.e. players who play often and with high stakes, like to choose games with high volatility because they like to bet a lot and do not care about small winnings.

Low or low volatility slots are the opposite. They don't pay out extremely high winnings, but you can often enjoy smaller wins. Medium variance games are usually suitable for most players and offer something for the types of players who like to see bigger payoffs.

Ultimately, you should be playing the slot that you enjoy the most, but the aspect matters and the free slot games give you the option of knowing exactly what the volatility is.

What bonuses are there with online slot machines?

Numerous bonus promotions are offered in the online casinos, so that you can find the best way to start playing. There are these mostly offered options:

  • No deposit bonus or bonus without deposit: when registering at the casino and completely without depositing real money, you either get free spins on one or more slot machines or a cash bonus that you can use in the casino.
  • Welcome bonus with deposit: for the first or first deposit you receive a certain percentage of bonus money (e.g. 100% bonus up to € 250), which doubles or multiplies your stake. There are also often free spins or a combination of free spins and a cash bonus.
  • Slot Reload Bonus: This is available for renewed deposits, even for existing customers, so if the welcome bonus has already been activated.
  • Cash Back Bonus: some casinos have cashback offers. In the event of a losing streak, certain sums will be credited to your account so that you are motivated to continue playing.

The best way to get to know a new online casino is undoubtedly the exploitation of a free bonus. You have to register with most casinos, but do not deposit anything. However, many casinos also offer the machine games for free to play without the need to log in.

Difference between a free game and a game with a bonus

There are two different options for playing a slot machine for free. Once you can look for an internet site, e.g. there are numerous test sites where you can try out many slots for free. Many reputable software manufacturers of casino games also offer free play on their product pages. This is so that the players can test the existing games and also to get to know new games and get excited about them. No registration at a casino is necessary to play for free. However, you don't get a bonus either, so you can't play for real money, you only play for play money. The machine provides you with a certain amount of play money, so you can try out all the features that are offered when you play a slot machine for free, without having to register.

However, the whole thing only gets really exciting once you decide to claim a free bonus. Registration at an online casino is required, but you do not need to make any deposit. Then this is called free playing with a bonus.

Your personal slot strategy

It's, of course, recommended that you get to know the slots before playing exactly, seeing you what it's for functions, whether there are free games, a bonus round and what the scatter or the wild symbol does. How many paylines are offered and you can set them and thus influence your profit combinations and profit opportunities. What is the minimum insert and the maximum operation and there is a jackpot or even a progressive jackpot. What pays every symbol and is there a risk game after every single gain, with which you can multiply your profits? All these are questions you are at the reputable online casinos For example, you can answer by either playing for free in demo mode or fun mode without using real money or by taking advantage of one of the online bonuses offered.

Your personal attitude

Since there is really no real slot strategy, but you should then play to improve your chances of profits, you have to learn to manage your balance properly and also grant a generally positive game setting.

You should always play with a clear head and remember that fun should be the main focus. Do not choose games that you do not like the topic at all, just because they may be advertised through some casino promotion or a free bonus. You have to enjoy the sound effects and the graphics, and the game theme in general has to be likeable. If something about the machine annoys you, switch to another one right away.

Only real money games when you are concentrated and have a positive default setting. Do not think negative and possibly "that you can not win on slots anyway". You know that the opposite is the case and that you have a profit by choosing the right slot and the volatility risk of the machine and your own player type, quite good chances of winning.

Manage your balance correctly

The better you manage your player account, the longer and more successful you will be able to play and the more fun you can have. It is advised that you set your budget per game session. That shouldn't depend on how much you have in the account, but how much you think you want to wager on a game. Use as much as you can spend without having to worry if you have been out of luck and lose. Take a break and if you have won, don't go straight back to everything.
