Online Slots with the Best Payouts

A slot machine’s payout rate is its payout percentage, known as an RTP (Return To Player). This index allows you to find out how much the slot pays out. Out of all the online slot machines, the best payouts for winning high jackpots are found on video slots. These games have RTPs of +/- 96% while offering great jackpots.

RTP, a crucial factor in payouts

The payout rate indicates at what rate a slot pays. If we look at the slot machine HOT INK, it has a very fair RTP of 96.49%. This, in turn, means the casino’s edge is only 3.51% (100% – 96.49%) and that 96.49% of players’ bets are redistributed. However, that doesn’t mean that on every pound wagered the player receives 96.49% in return. In practice, the money bet on the slot is transferred randomly; overall, there are losers and winners.

How can I win?

The trick to coming out on top is knowing when to stop playing if you’ve already won a jackpot. Of course, as with any game of chance, luck is the only factor determining the results. However, choosing slots that have a high RTP while having good jackpots is, in our opinion, the best advice to follow.

Calculating the best payout rates

The payout rate for a slot machine is generally calculated over one month. This calculation is the ratio of all bets to all money paid out by a specific slot machine. It’s important to remember that only the luckiest players take home the jackpots, and the rest lose everything. In the process, the casino takes its profit margin (100% – the RTP rate = the casino’s edge).

Ideal payout rates

What is the best RTP? And which slot machine should you choose? On our guide to the UK’s best casino sites, we believe the bets payouts are on slots with RTPs of 96% to 97.5%, and never above. For the game to be exciting, you’re also going to want the jackpots in play to be high. Typically, if an RTP is too high, there won’t be much to gain.

Slot machine payouts

  • Good payout: a slot that has an RTP greater than 96% and less than 97.5%,
  • Average payout: a slot that has an RTP of 94% to 95.99%,
  • Bad payout: a slot that has an RTP lower than 94%, or higher than 97.5%.

When trying to choose the right slot machines, it’s best to avoid games with excessively high RTPs. In all honesty, games that have payout rates above 97.5% are a sham. Why? Because the jackpots in play are so small and there’s no chance of winning any serious money.

The payout rate impacts the volatility of a slot machine. Volatility indicates whether a slot pays out often or not. The more volatile a slot machine is, the more it will pay big jackpots, but spaced out over time. In contrast, a slot with low volatility pays out often, but only small amounts of money each time.

Volatility levels

The volatility of slot machines can be classified into three groups. A parallel can be drawn with RTPs to differentiate these groups.

In general, these are the volatility levels of slots:

  • Low (RTP + 97.5%),
  • Medium (RTP from 95% to 97.49%),
  • High (RTP from 85% to 94.99%).


Most slots players in the UK seek fair value for money. The goal is to play on slots that offer the biggest jackpots with the highest odds of winning. Finding the best payouts is a challenge with slot machines.
Fortunately, there are slots on the market that pay better than others. These games are found at Britain’s most popular and trusted online casinos. Lastly, video slots with an RTP of +/- 96% are those with the biggest jackpots.
