What is the Slots’ Random Number Generator?

What is the Slots’ Random Number Generator

In terms of slots, a Random Number Generator (RNG) is a neutral software that produces a random number per spin. The number stops the wheel, resulting in the final outcome of the slot game. In the same game, the same number always results in the same outcome. It determines the exact positions of the slots and the final winnings. The RNG cannot be influenced or predicted.

Why is RNG Important?

RNG is a way to ensure fair results for every slot game. Independent game testing serves to prove this. Industry experts set out to test different slot games to ensure they all operate according to the RNG software. Player luck and randomness are the only factors determining the outcome.

Slots Return to Player Explained

Slots Return to Player Explained

Percentage of Return to Player or RTP% is the average return players get from a game. The percentage is calculated based on multiple parties in a game. High RTP in a slot game is great news for players. This means that, on average, they’ll win back more than they invested.

In essence, RTP is the reverse of House Edge. House Edge is the mathematical advantage the casino has over the players. It refers to the average amount of money the casino makes from deposits.

Simply put, calculated RTP and House Edge determine the odds for each slot game you play (RTP = 100% – House Edge).

Methodology

We did thorough research to discover and confirm the RTP rates of the top slot games. As a rule of thumb, any RTP between 96% (max 4% House Edge) and 99% (1% House Edge) is considered high, and all of the best slot games fall into this high RTP category.

Firstly, we checked the info section of each game to see if the RTP was clearly stated. When it wasn’t, we researched the game online, seeing if some database or the game’s official website had the info about the RTP.

Finally, if the RTP wasn’t stated anywhere, or if we wanted to confirm it, we did the following:

  • Open the game
  • Right click on inspect
  • Click on ‘Network’
  • Click on ‘XHR’
  • Reload the browser
  • Check for access to the file
  • Locate RTP

These top high RTP slot games are all ‘low-to-medium variance,’ which means that the number of wins will be higher, but the amounts won will not be as significant. Some bigger wins and payouts are still possible, though.

One thing that can elevate high RTP games is a free-play option. Our recommendation is Starburst – a game that offers great free spins bonuses for Canadian players, combined with a high 96.01% RTP rate.

How Are Slots’ Payments Determined?

  • Slot payout frequency and amount are determined by RNG and RTP.
  • The average House Edge for slot games is 8%.
  • Hit frequency is a percentage that can determine the number of payout rolls per spin.
  • The average hit frequency is 1 in 5, which is 20%.
  • RTP calculates the average amount of money a game returns to players.
  • Hit frequency calculates the average number of wins per spin.
  • Combining the two gives you the odds of winning a bet.
  • You can also calculate how much you can win or lose over time.
  • The higher the hit frequency and RTP percentages, the better the odds for players.

Where Does Slot Volatility Come Into Play?

Where Does Slot Volatility Come Into Play

Volatility is the last factor influencing your odds of winning and the amount you win at a slot game. It is a measure of the difference and unpredictability between results. The larger the distance between the results of subsequent spins, the higher the volatility. High volatility slot games are riskier – payouts are larger but rare and unpredictable.

While volatility is a measure of unpredictability within a given time frame (a week, a month, a year), variance is the same measure but without time limits. Variance measures the volatility of the game overall.

If you tend to play several times in a row, high volatility/variance games can get you to chase a huge progressive jackpot if you tend to play several times in a row. This way, you risk losing more in the long run. Low volatility/variance games will produce more modest wins, but they will be more frequent.

Methodology

The easiest way to check a slot game’s volatility or variance is to look at the size of its jackpot. We examined each slot on the list exactly in that way. Large jackpots, such as CAD 500.000, guarantee high volatility in the game. Smaller jackpots are indicators of lower volatility. This means that you can hit them more often than the high one.

The same rule applies to payout sizes or bonus features. The higher the payouts, the higher the volatility, and vice versa. The more generous the extra features or bonus rounds, the higher the volatility.

High volatility games are peculiar, as they’re very risky, and not all players are equipped to handle them. Without a good bankroll, these games can get you completely broke very fast. Some high-volatility games, like Starburst Xxxtreme, offer a max payout of 60,000x your original stake. The risk is huge, but this may be a life-changing opportunity for brave and lucky players.

Online Slot Types & Best Picks

Classic Slots

Classic online slots are simple in design and inspired by the first physical slot machines invented. The gameplay is easy – these slots have three reels and three pay lines. The symbols are of different fruits, a shamrock, a bell, and, sometimes, a joker.

Contemporary online classic slots may have polished graphics, but some may intentionally make the interface look vintage and worn-in.

  • Double Whammy
  • Total Overdrive
  • Break Da Bank

Five-Reel Slots

Five-reel slot games are similar to classic slots, but they add two more reels to the existing three. Five-reel slots can have multiple pay lines, and these vary between games. However, the average number of pay lines is twenty.

Five-reel slots are a slightly updated version of the vintage classics. That’s why some of them may feature extra bonus games, arcade mini-games, and animations.

Multi-Reel Slots

Multi-reel slots take things up a notch. They have a bigger number of reels and pay lines. Some may even have up to a hundred pay lines. Unlike classic and five-reel slots, multi-reel slots offer payouts through diagonal lines or zig-zag lines.

Payouts can be read from left to right or from right to left. Multi-reel slots provide more winning opportunities and include extra features and interesting animations.

Progressive Slots

Progressive slot games are not about the number of reels or pay lines but about the jackpot strategy. These slots take a bit of every bet you make and add it to the big jackpot. Over time, the jackpot rises thanks to all the players who bet on the game. Once a player hits the jackpot, the player takes all the winnings home.

Progressive slots are especially lucrative when a free spins bonus is available. Arguably the best progressive slot game offering free spins to maximize your luck is Mega Moolah.

Slots With Special Features

Most modern slot games are much more complex than classic slots. This means that they often feature various extra modes or bonus offers. Some have special symbols that bring more wins. Others offer bonus rounds or separate mini-games for lucky players.

Though most features are about getting bonus rounds, such as free spins or bets. Free spins are some of the best features, as they allow players to spin for free, getting a chance at winning some cash or even a large, progressive jackpot.

Common Slot Myths

Common Slot Myths

Myth 1: Online slots pay better during certain times

No, this isn’t true. RNG makes sure that no outside factor influences the result of slot games. The probability of winning is the same at all times of the day.

Myth 2: You can tell when a slot machine is going to hit

Thanks to RNG, it is impossible to predict a hit at a slot machine. This doesn’t just apply to high-volatility games. Low or moderate-volatility games are equally unpredictable. There are no educated guesses.

Myth 3: Some slot machines are ‘luckier’ than others

No slot machines are luckier than others. They may have different technical setups, such as different RTP, volatility, or hit frequency, but winning a bet solely depends on your luck.

Myth 4: Slot machines are programmed to pay on a cyclical basis

Some people believe that you can hack the RNG cycle of a slot, influencing the payout. This isn’t correct. RNG cycles produce thousands of numbers per second and cannot predict or control the outcome.

Myth 5: Stopping the reels manually is better than autoplay

Thanks to RNG, it doesn’t matter if the reel is stopped manually or automatically. However you decide to stop it, the end results are always randomly generated.
