A way of understanding the payout of casino games is the house edge, this is the opposite of RTP and is the percentage that signals the risk and chances of losing.

There’s a huge selection of online casino games with huge payout rates, these games come from Microgaming, Playtech, Blueprint Gaming, NetEnt and other software developers.

How is a Casino Payout Rate Calculated?

The online casino payout rate gives you an idea of how often the casino pays out. The house often has the edge but only by a small percentage. Each game varies in percentage but there is a total casino payout percentage that gives you an idea of how likely you are to win.

All games on a casino site have their payout percentages averaged this total will then be the casino payout percentage that’s given. Payout percentage ranges from 70% and 99%, the higher the number, the more chance you have of winning.

What is the House Edge?

The edge always goes to the house, favouring the casino. The payout percentage is the likelihood of you seeing a win or return. If the payout percentage is 97% then that leaves 3% – this is the house edge. Calculate the house edge by subtracting the payout rate from 100.

Casino Payout Percentage vs RTP

Casino payout and Return to Player percentages are calculated in a similar way, offering an idea of how often you can expect returns. RTP is the payout calculation for slot games and a casino payout percentage is an accumulation of all the games on a site and how often they payout.

Casino payout percentages accumulate all the games on the site and offer an average payout rate. This is a gauge for how likely a casino site is to payout, if the percentage is 96% then in theory for every £100 staked, you have a good chance of landing £96 wins on average.

The edge always goes to the casino but the best payout casino sites offer less risk for players.

The volatility of a Casino Game

Volatility is also known as variance and this differs from RTP or an online casino payout rate. Variance provides details on how often a slot or casino games pay and the size of the payouts. High variance slots are volatile, they pay less often but pay bigger wins. The volatility gives us more of an idea of the quantity of the returns.

Here are the different types of volatility:

  • Low Variance Slots – Low variance slot games provide regular wins, spreading the amount. This means smaller wins but more frequent.
  • Medium Variance Slots – Medium volatility slot machines are more balanced, with regular wins and some big wins too.
  • High Variance Slots – High volatility means more risk, there are fewer wins but when you do land them, they come with big returns.

Slot Hit Rate of Online Casinos

This term refers to how often you can expect to land a winning combination on any given spin on online casinos.

  • High Hit Rate – more frequent but lower wins. Sometimes smaller than your bet amount.
  • Low Hit Rate – fewer wins but bigger prizes.
  • As you can probably tell, slot hit rate and volatility are interlinked when it comes to wins. Something to bear in mind when it comes to looking for the best payout slots online.

Tips for Choosing the Best Payout Slots Online

Here are our top tips to look out for with the best online casinos and best payout online slots:

  • Look for game information before you start to play. This will give you an insight into all the areas discussed above.
  • Try an online slot demo game beforehand. This will give you a feel for how it plays and more importantly pays out.
  • Look for an online casino with a high RTP. Ideally over 96%
  • Pick a slot game with free spins. Once you trigger the free spins you will be guaranteed to be in profit from any winnings.
  • Avoid ‘show games’. Video slots or games based on a movie. These games tend to be flashier but harder to land the big wins on. Generally made to appeal to fans of game theme.
  • Remember progressive jackpots may payout less frequently. The higher max win might be alluring, but chances are, you will be facing the long game if you try to win it.

Anything Else to Know to Know before Playing Best Payout Slots Online?

There isn’t a one size fits all formula when playing online video slots. Yes, there are statistics and variables to bear in mind. But these will vary from game to game.

How much you win depends on you too. How much you are prepared to stake? How long do you want to play for? If you are planning to solely win the jackpot or chase your losses, you may find things move against your favour. You should play slot games to enjoy them with sensible amounts you can afford to lose.
