What is RTP (Return Percentage)?

RTP - Slot Machine Return Percentage. Focusing on it indicator, you can understand how many bets you can return during a long gaming session.

There are no slot machines with 100% RTP as in this case casinos would operate at a loss. The rate of return of branded slots ranges from 92 to 98 percent. You can calculate the RTP by dividing your winnings by your bets multiplied by 100%.

The percentage of return is purely statistical. Machines with the same RTP level may result in winnings with varying frequency.

It is important to know not only the rate of return of the device, but also to understand how this parameter works in practice. So an RTP of 97% means that the player will return 97% of all bets made on the slot machine , but only in the long run. It is a mistake to believe that if you spend 100 coins for 10 or 100 spins, the amount won will have to be 97 coins. Minimal the length of the game distance is 1000 spins, and slot makers check the RTP on several million revolutions of drums.

What is dispersion (spread)?

Dispersion is a statistical term. The dispersion level of the devices shows the deviation from the RTP, set by the manufacturer. To be clear: there is a certain slot with an RTP level of 98%. IN In theory, it reimburses players 98% of the money spent on betting. However, the payback it is calculated under the conditions of a long game session and with a large number of players. If you will only make a few dozen turns, the RTP will not be respected and the variance will increase. If you make a lot of bets, the opposite is true: the variance will decrease, and the RTP reaches the specified value.

What is volatility?

Volatility and variance are often confused, but they are different concepts. Volatility is more related with gameplay. It shows how often and what the winnings will be their size. The volatility can be determined from the magnitude of the multipliers rainy weather. Due to the level of volatility, online slots can be divided into those that have high, medium and low volatility.

Average volatility

Medium volatility slot machines have multipliers from x5000 to x10000. Te the games have a medium level of risk and bring moderate wins. Such devices are suitable for players with any capital and you don't have to wait too long in them cash prizes.
The most popular medium volatility gaminators are Snowing Luck (Spinomenal), Sakura Fruits (Amatic) Fortunium (Microgaming).

Low volatility

Low volatility slot machines multipliers do not exceed x5000. Such devices are characterized by minimal risk. Wins in them often fall out, but their value is not very high. Low volatility models are perfect for players who prefer small, frequent payouts with rare large jackpots.

Examples of low volatility fixtures are Playboy Gold (Microgaming), All Ways Win (Amatic), and Justice League (Nextgen).

High volatility

The multiplication factors of devices with high variability are greater than x10,000. Playing in such games, you can place bets for a long time and be left with no prizes, but then win big jackpot. High volatility slots are popular with players who are prepared for high bets who are willing to be wait patiently for your big winnings.

Notable high volatility slots - High Society (Microgaming), Medusa 2 (Nextgen).

What is the relationship between RTP and volatility rainy weather?

RTP and slot volatility are different things. The RTP indicates what percentage of funds a player gets back over an extended period of time playing. Volatility is even more accurate than the RTP, it shows how much money will remain in the balance under end of the game session. For example, a slot machine with minimal volatility and an RTP of 95 percent will bring small but frequent wins. With a capital of $ 10 at the end of the game you can get a prize of $ 15. In other words, the value returned will be 150% - on a lucky coincidence.

If the volatility of the game is high, then for the initial 10-20 or even more spins you can win nothing. However, there is still a chance that during a long gaming session there will be winnings that will exceed 1000 times the bet. In this case, the return of the slot per session will significantly exceed declared RTP at 95%. However, this happens very rarely.

Slot Machine Strategies

While there is no strategy that will allow you to keep winning on slots, there is several systems that allow you to increase the probability of winning. E.g:

  • Smart Gambler - place minimal bets on spins, no forgetting to activate the risk round;
  • Moonshot - reduce the number of active lines on the device to one, to get a big prize by increasing the bet;
  • Reserve Martingale - bet your winnings on previous round, and in case of loss - return to the original bet;
  • Casual Player - Make the same bets until you don't you win a certain amount or choose not to stop the game.

Many people use the Martingale strategy, but despite its popularity, neither is it too profitable. By following this system, you can recover your initial bet but get a good one profit, even in the long run, is unlikely.
