Online slots history

Online slots are one of the most popular types of gambling entertainment offered by gaming portals. For casinos, they form more than 70% of the profits, as most casino visitors choose them. This is due to the wide variety of themes, formats, ways of forming prize lines and the possibility of one win to cover previous losses.

Online slots were a new step in the development of slot machines, which have existed for more than a century. The first forebears of slots appeared at the end of the XIX century and were driven not by an inbuilt algorithm, but by the mechanics. Inside the slot machine were three drums with symbols on them. Pressing the lever started the mechanism that set the drums in motion. 

The next stage in the development of slot machines was the emergence of electromechanical. The engine capacity of several horsepower was responsible for their work. They began to appear in the early XX century with active industrialisation and the development of technology. In their principle of operation, they differed little from their predecessor, except that the drums were driven not by a system of mechanics, but by a motor and electrics. Such machines enjoyed great success up to 1970-1980s, until video slots were created. They eventually replaced conventional slot machines.

Video slots were controlled electronically, the process of depositing money and receiving winnings were automated, and the sequence of falling out symbols on the playing field was responsible for the random number generator. Since the first video slots to our days, they have gone a long way to improve. Now they are full-fledged computers, providing bonus games, special symbols and other additions. Online slots are the same machines, but located in an online casino.

Principles of online slots

In mechanical slots, the symbols and numbers on the playing field were chosen randomly, as there is no influence on the rotation mechanism. For video slots and online slots, the principle of randomness has been retained, but the order of the falling symbols determines the random number generator. It has a lot of settings and each game manufacturer has a different one. These special algorithms work independently, so casinos can not change the rules of the game. The player’s win in slots is solely the result of chance. It’s not worth it to count on a regular income from bitcoin slots, as it is impossible to calculate in advance the order of falling out of game symbols.

Slot machines are created by dozens of certified companies around the world. Among the most famous are Betsoft, BGaming, Pragmatic Play, Endorphina, Igrosoft, NetEnt, Amusnet, NOVOMATIC, Amatic, Belatra, 1×2 Gaming, Fugaso, Booming Games, Microgaming, Playtech, Quickspin, Yggdrasil Gaming, Evolution Gaming, Evoplay, iSoftBet, Play’n GO, Playson, Red Tiger, ELK Studios, Push Gaming. Most providers are licensed and pass from independent studios that check the compliance of the software with the declared parameters.

Terms of winning in online slots

Most online slots use reels that are familiar to players, which display the results of a spin on the screen. Each reel has a number of symbols that correspond to the stated theme. A game coordination is formed after a full rotation of all reels. If the field is a match of identical symbols on the lines that are marked in the rules, the bettor receives a win.

The size of the winnings is calculated by a simple formula. The amount of the bet is multiplied by the coefficient. The latter is not fixed and depends on the game position. Each symbol on the reel has its own multiplier, which increases depending on the number of repetitions on the payline. Multiplier of one bet can reach x3000 and more. Everything depends on the rules of the slot machine, so read the rules before each launch of the game.

There are several types of slots, depending on the number of reels that are used in the game.They can feature different symbols and signs, the variations are found differently, depending on the theme. Standard can use card denominations and thematic symbols such as pyramids, celebrities, film characters, Vikings and others. There are classic slot machines. These usually use fruit symbols as well as the numbers 7, 77, 777, diamonds. The base game symbols are worth different amounts. The higher the multiplier of the combination, the less chance of collecting it.

For example, in the slot Fruits N Stars are images of fruit. The size of the win depends on the size of the bet and the number of lines in a particular machine, which you can read about in the rules of the casino. Also online slots, unlike their mechanical predecessors, got additional features: Wild, Scatter symbols, free spins, bonus games.

An important characteristic of the slot is the presence of special symbols and prize functions. Special signs come in three varieties:

• Wild, or wild symbol. With its help, you can collect a winning combination, if there is not enough one or more symbols. In some slots, the wild gives an additional multiplier, which allows you to get more profit. In bonus levels, the wild symbol can get more favours.
• Scatter, or scatter symbol. Makes up paying combos outside of the sequence stipulated by the rules. Some slots pay winnings simply when it falls on the playing field. Usually scatter is used to launch bonus rounds, such as free spins. The number of freespins may or may not be limited. In some best bitcoin slots the more scatters fall out, the more freespins the player gets.
• Bonus sign. Responsible for activating the bonus round, which is different from the standard game and brings big wins. Bonuses make gamlay more exciting and increase the payout of the slot. It can also activate respin or other bonuses.

The prize options are different for each slot machine, which makes slots the most varied and interesting gambling options in the casino.

RTP online slots and variance

When choosing bitcoin slots online it is important to pay attention to two such indicators as the return percentage (RTP) and dispersion (volatility). They are very important as they determine the chances of a player to win and the overall profitability of a slot machine.

Payout percentage (Return to Player, RTP), it is prescribed in the programme of each slot and means the percentage of return of money to the player, as well as the profit of the casino. RTP will never be 100%, as no slot gives back 100% of accepted bets. A figure of 97.5% or higher is considered good, as the casino’s advantage is no more than 2.5%. In cryptocasinos, you can find games with a 99% return percentage. Most slots have an RTP of 96% or higher.

The payout percentage is regulated in many jurisdictions by law, that is, developers do not have the right to underestimate the figures. All game operations are not recorded on the servers of the casino, and the software provider, so that it is impossible to change the RTP slot. The activity of developers is strictly checked by regulatory authorities.

It is important to realise that the RTP is calculated on an infinitely large value of spins, not on a short distance. You should not expect to be able to return 97% of your bets in one gaming session if the RTP is 97%. At the moment, the return rate can fall below 50% or rise above 120%. In the first case, players in the moment are more likely to lose, and in the second – to win. It is impossible to guess in what position the slot machine is in.

Slots variance or volatility is an indicator of the regularity and magnitude of winnings. It is divided into three main types:

• Low. It indicates that there will be a lot of wins, but their amount is minimal.
• Average. It is considered an optimal indicator, as there is a balance in the number of wins and their magnitude.
• High. This indicator of dispersion indicates that wins in the slot will be rare, but their size will be large.

Knowing the payout percentage and volatility of the slot you can adjust the level of risk, but to achieve an exact guarantee of profit from the gaming session is impossible.

How to determine the winning symbols

All slots work on a random number generator, which, taking into account the laid parameters of the machine, forms the result of each draw. The casino and the software manufacturer cannot make changes to the formation of each combination, so all results are random. With the help of randomiser every second there is a generation of thousands of numbers, it is impossible to predict or calculate the result.

The random number generator runs continuously, and it does not keep track of the number of times the user tries. The algorithm does not know whether you made the first or the last bet, how long you have been playing. All results are random and do not depend on which casino the bettor is playing at.

Mathematical algorithms are used to form all combinations. The GSC does not use logical principles of selection, and the variants of possible combinations are huge. When starting a slot machine algorithm forms a number of random numbers that determine the final combinations of symbols that fall out the user. This rule also applies in bonus modes. HSC does not give the opportunity to calculate the result, but guarantees safety in terms of fairness of the game.

If you compare the different modes of slot machines, then the following formats for determining prize combinations are distinguished:

• Paylines – the rules specify 1-10 paylines, less often more, when any of them falls out, the bettor receives a win;
• Megaways – the payout is formed by matching identical symbols on adjacent reels, the number of prize lines is limited by the number of reels and symbols on them;
• Cascade – this is a mechanism in which winning symbols disappear, giving way to new ones, which gives a chance to get additional winnings on one spin.

These are the three most popular formats for determining prize combinations in BTC slot machines.

How jackpots are formed

Jackpots are another distinctive feature of slot machines. There are two types of jackpots in slots – progressive and fixed.

Fixed. This is an additional chance to get a big win in slot machines. Their size is prescribed in the rules and usually depends on the amount of the bet, as there is a multiplier for each. The size of the possible winnings is determined by the provider and can be received an unlimited number of times.

Progressive. An accumulative jackpot is formed from the percentages of bets made by all players on a slot or several. It can be like a network jackpot, when deductions are made from all slots of the same provider, but different casinos. Some casinos run their own jackpot draw. It is formed from the deductions of all customers.

GSC and the principle of its work

HGF is a special programme with a predetermined algorithm. Versions of the random number generator are constantly being improved to adapt to evolving technology and increasingly advanced software. Despite the wide variety of variants, the majority of random number generators use a similar principle of operation:

The DST generates a random number.

• The slot module calculates the stop point of the reels.
• The game stops the reels and reads the result.
• The result is displayed on the screen in the form of symbols.
• The outcome is determined only by luck.

It is impossible to bypass the principles of security in the work of the GSC. We do not recommend buying any schemes to earn money in the casino, as they are scammers who earn money on the affiliate programme or steal personal data. Any winnings in casinos are the result of luck.
