What Factors Affect the Online Slots Payouts?

When you are in the online casino market looking for high-paying online slots, it's best to familiarise yourself with some technicalities.

All uk slot games online are built to stand out, and the payout system is also designed in unique ways. Many factors affect the payout of a slot game, including RTP, volatility, and hit frequency. Each factor plays its role in affecting the payout unless you find two identical games from the same software provider. Read below to find out how different factors affect the slot's payout.

Role of Return To Player (RTP) in Slot Payouts

RTP or Return To Players is a common term all slots players are familiar with, but what does it mean, and why is it mentioned in every slot game?

The RTP is the percentage of sum wagered against the money amount paid back to a player over time. Most online slots feature 94%, and we don't suggest that players take a chance on slots below 94% RTP. The chances are high that you have been playing slots with more than 96% RTP.

Let's explain it in simple terms: if you wager £100 on a slot game with 96% RTP, you will get £96 in return. Let's be clear that it's not the case every time some players win more than anticipated, and other times they lose more.

Slots are a game of chance; you may hit a six-figure jackpot with a £10 bet, or you lose spin after spin on the same slot game. The RNG technology that operates these slots makes sure that every spin is random. Keep reading, and you will know which slot games have the highest RTP in the market.

Role of Volatility/Variance in Gameplay

Volatility, or sometimes referred to as variance, is the frequency of a slot payout throughout the game. It is subdivided into three categories, namely:

  • Low Volatility: Wins are frequent in low volatility slot games, but stakes sizes are small.
  • Medium Volatility: A popular subcategory that offers ample value, win and winning frequency is relatively higher than low volatility. Medium volatility slots are more inclined towards high volatility than low.
  • High Volatility: Slot with high frequency offers high-value wins but less frequently. It's hard to land bonus rounds and score winning combos, but the results are super sweet.

Hit Rate Relation to Slots Volatility

Hit rate or hit frequency is a term we use when explaining the frequency of landing winning combinations on the reels on every spin.

  • Low Hit Rate/Frequency: Win are fewer in number, but prizes are bigger.
  • High Hit Rate/Frequency: Frequent wins but lower in amount, sometimes smaller than your total wager.

Where wins are concerned, volatility and hit frequency are interlinked, and it is important to consider these factors when looking for high paying slots online.

6 Features to Consider when Choosing a High Paying Online Slot 2021

Online slots are chance games, but there are certain factors that players should consider to increase their winning chances. Look out for these slot features when you are planning to win big:

  1. RTP: The RTP is an important factor that gives players an average of how much payout they should expect from a slot. Every slot game has an RTP; the higher the RTP, the more money you will get and vice versa.
  2. Bonus Games: You can boost your winning chance on a slot game with bonus games that primarily include free spins. These bonus rounds offer an opportunity for substantial winnings, and such slots are referred to as Loose slot games.
  3. Volatility: RTP and volatility are often mention side by side, and the latter explains the frequency of the wins on the slot games. The higher the volatility, the lower the winning frequency and the lower the volatility, the higher the winning frequency but with small wins.
  4. Bonuses: Don't miss out on bonus offers we offer at Thor Slots, as you can win cash rewards without spending any dime on wagers. Free spins are a regular occurrence on Thor Slots; you can enjoy tons of slot games and get a chance to win a substantial winning amount. These bonuses are your best chance to get the load off your pocket.
  5. Progressive Jackpots: If you want to win big, your best chance is Progressive Jackpot slots as they can win players six or plus figure winning amount depending on the pot. The jackpot on these slots increases with every wager.
  6. Managing Bankroll: It's important to consider your bankroll when paying for slot games and planning to win big. You cannot increase your winning chances on a minimum £5 bet slot game with £10 in your pocket or account. You may or may not hit the jackpot with just two attempts.
