Calculating RTP
RTP, or Return to Player, refers to the theoretical percentage of total money wagered on a slot that’s paid back to players over time. A typical slot operates at around 96% RTP. This means, theoretically, for every £100 wagered, the game returns £96 to players as winnings, with the remaining £4 representing the house edge.
RTP can be simply calculated with the following formula:
RTP = ( total winnings / total wagers ) x 100%
It’s crucial to remember that RTP is a long-term theoretical value. Individual session results will vary, as RTP reflects performance over millions of spins. If RTP were consistent across short periods, gambling would become predictable. In practice, some players may win back much more than 96%, while others may win back less or nothing.
UKGC requirements around RTP
The UK Gambling Commission mandates that all slot games display their RTP. This transparency ensures players are informed about the theoretical returns of the games they play, promoting fair and responsible gambling.
Should I play high RTP slots?
Ultimately, we always recommend choosing high RTP slot games over low RTP slots, because they typically pay out more over the long term.
But while RTP is indeed an important factor in determining a slot game’s payout behaviour, it’s not the only one. Variance and max payout also significantly impact your gaming experience.
Deviation from RTP – Variance or Volatility
Variance, also known as volatility, measures the deviation from the RTP in a game’s payout pattern. Low variance slots offer smaller, more frequent wins, closely aligning with the RTP. High variance slots, on the other hand, can result in larger but less frequent wins. For example, a high variance slot with a 96% RTP might give one player a massive win within just a few spins, while another player might not see a win for ages, depleting their balance before seeing a single payout.
You can get a sense of a slot’s variance from the paytable. If there are lots of low-paying symbols, it’s likely a low variance slot. Likewise, lots of high-paying symbols means the slot is probably more volatile.
Think about the types of wins you’d like to see and how big your budget is, and pick a slot based on that:
A low variance slot might return small, steady wins frequently.
A high variance slot might have long dry spells but occasional large payouts.
Payout potential
Payout potential indicates the maximum amount that can be won in a single spin, irrespective of RTP or variance. For instance, a slot with a high payout potential might offer up to 10,000x your stake. High max wins can be found in both high and low volatility slots.
RTP and jackpot slots
In progressive jackpot slots, a portion of each bet is allocated to the jackpot pool. However, many jackpot slots only let you win this prize under certain conditions — for example, you might have to play the maximum bet to qualify for the jackpot.
As the jackpot will account for a significant portion of the RTP, the returns in the base game will typically be lower unless you’re actually playing for the jackpot.
How to find the best casino with high RTP slots
Finding the best casino is crucial for maximising your winning potential. Here are some expert tips to guide you in selecting the right online casino.
Only play at casinos licensed by the UKGC
Always choose casinos that are approved by the UK Gambling Commission (UKGC). These casinos adhere to strict regulations, ensuring gameplay is fair and transactions are secure. Experienced gamblers understand the importance of playing at reputable UK casinos, where the chances of fair payouts are higher.
Consider slot game developers
When eyeing up a potential casino with high RTP online slot games, browse the library to see which developers it stocks. Top names known for high RTP slots include Thunderkick, NetEnt, NextGen, Yggdrasil, and Playtech. These developers are renowned for creating games that not only offer high RTP but also feature exciting bonus rounds, free spins, and substantial max wins.
Evaluate bonuses and promotions
It’s always worth taking advantage of whatever bonuses and promotions are up for grabs. Look for offers such as deposit matches and free spins, although be sure to read the T&Cs carefully as they may not be eligible for use on high RTP slots. Other terms to watch out for include the minimum deposit required, maximum bet limits, withdrawal caps, wagering requirements, and bonus time limits.
Assess payout speeds
Fast payouts are a priority for many casino players. Check the payment policy of your chosen casino with best payout slots — you’ll want to be sure they process requests quickly and efficiently, while also supporting the quickest payout methods like PayPal or Visa Fast Funds.
