Understanding the Paytable and Variance of Slot Machines


Before you play a slot machine, you should know about its paytable. It contains key information about the symbols that are likely to win, how you can trigger bonus rounds, and more. It also shows the active paylines. Understanding the paytable is important because it helps you to understand how the game works. It can also help you to determine how much you can win.

Random number generators

Random number generators, or RNGs, are computer programs that produce random numbers. They are designed and coded by humans, but they behave like random numbers in a certain way. Usually, they use some sort of seed number to generate the random numbers. In some cases, the seed can also be another number or data that the machine requires.

In online slots, the random number generator doesn’t use a single seed, but rather a cryptographic hash function. The secret methods used by slot software providers are proprietary and are kept secret. However, if you can replicate the entire mathematical formula, you can beat the house.

Return to player

Return to player slot is one of the most popular games on online casinos. It is a game that features symbols of poker, blackjack, roulette, and more. Its gameplay is very simple and easy to learn. In addition, you can check its Return To Player percentage online before you play it. Many casinos have their own websites that allow you to check out the RTP of any slot before you play it. This will give you a better idea of how to play the game before you make a deposit.

The RTP is a number that shows the percentage of a slot game that will be returned to the player if the player loses. Knowing the RTP helps you plan your bankroll and betting strategy. A good Return to Player slot will have a high RTP.


The Paytable for slot machines is an important tool to know the odds of winning the top prize. It is a list of payouts for different symbols, which changes as your bet increases. This table also shows the number of paylines and the chances of winning the top prize for a certain bet size.

Bonus rounds

Bonus rounds on slot machines are extra games that can be triggered by specific symbols on the payline. These symbols can include the game’s logo or images of characters. Most bonus rounds are free to play and require very little skill to win. However, there are some tips that can increase your chance of winning. These games can be a great way to win big without spending a fortune.

The rules for these bonus rounds vary from casino to casino, but they generally unlock once a certain combination of symbols is spotted on the reels. Most bonus rounds on slots offer a no deposit bonus. Although this does not guarantee huge winnings, it certainly makes the games more exciting.


Variance of slot machines is a measure of the risk involved in the game. Slots with high volatility pay the highest payouts and have the highest jackpots. As a result, they are very exciting to play. On the other hand, low-variance slots pay small but frequent prizes. The high-variance slots have huge progressive jackpots and bonus features. However, these games are extremely difficult to tell apart from low-volatility slots.

Variance is determined by the layout of symbols on the reels. Those with high variance may focus on the final three reels and have lower-paying symbols on the first three reels. Another indicator of the variance of a slot is whether or not the paylines run left to right.
