the game’s volatility. If a game has high volatility, landing patterns that trigger wins won’t come as easily as lower volatility slots, so you might need to adjust your bet sizes accordingly. Also, some high RTP slots may require higher bets to unlock unique features or even trigger progressive jackpots.

4. Consider game volatility

Even if a slot has a high RTP, that doesn’t necessarily mean there will be frequent wins. There’s also another factor to consider— volatility. If a game has a higher volatility, there will be less frequent wins, but those wins can potentially be larger than in a lower volatility game.

5. Read our casino reviews

We review many casinos to help players make the most informed decisions when selecting an Ontario online casino. When you check out our reviews, we cover aspects like the casino’s RTP (because this can vary from the game provider’s standard RTP), how the casino works, and the top games. We also review how transparent a casino is about its auditing. This will give you some extra information on how to choose your high RTP slot game and where to play it.

6. Set a budget and play responsibly

When playing any game, even with a high RTP, always remember that luck is a huge factor and that all potential payouts and winnings are theoretical. It’s advisable to set a budget and stick to it so that you won’t exceed your limits. Always play responsibly when playing any game.

What is RTP in Slots?

As mentioned earlier, RTP is the theoretical percentage a player will receive back from their wagered bets during a game. This means that if the RTP is 96%, and the player wagered $100, they could earn back $96. The remaining 4% is the House Edge, which is a portion that’s retained by the online casino from the player’s winnings. It’s really important to understand what a slot’s RTP is, as this can help players determine their budget and what percentage they might win back. Remember that these numbers are not set in stone as the RTP is calculated over lots of spins, so you might not see the expected payout in the short term.

Why are high RTP slots important?

Typically, a slot with a percentage higher than 97% is considered a high RTP slot. There are even slots with a 99% RTP!High RTP slots offer players a better chance of winning since the House Edge is lower. The slot’s algorithm brings a good percentage of the player’s wagered bets back to the player. When the RTP is lower, which means below 96%, that increases the House Edge and reduces the player’s chances and the percentage they can regain from what they’ve wagered.

Are High RTP Slots Safe to Play?

The short answer is YES. High RTP slots are the safer choice, as there’s the chance to win back a good percentage of what was wagered. They’re also legal in Ontario and can be found on plenty of Ontario online casinos. A fair slot game works with an RNG – a Random Number Generator, which is the algorithm that determines the unbiased outcome of casino games by generating random numbers and results. There are a few independent regulatory authorities that carry out regular audits to secure safe and fair games. Trustworthy casinos and game providers’ games are tested by auditors like eCogra and GLI, which encourages transparency, too.

When playing any game, however, always remember that in games of chance, there is no guarantee for how much can be won or lost so always exercise caution and play responsibly.

RTP vs Slot Volatility: What is the difference?

Slots can have high or low volatility, but this is different from a high or low RTP. Volatility determines how often wins land and how big or small they are. If a slot has low volatility, then it will pay out winnings more frequently but they’ll often be smaller. On the other hand, if a slot has high volatility, it isn’t going to provide payouts as often, but when it does, the payouts are often more substantial.

So, how do both of these affect a high RTP slot?

Progressive Jackpots and RTP

A progressive jackpot in a slot game takes a percentage of each bet players make as a contribution to the jackpot pool. The pool keeps growing until one lucky player wins the jackpot— meaning there is no fixed prize. Progressive jackpots also work with an RNG, so there is no way to predict when it will be triggered. The jackpot resets each time it’s been won, starting the whole process again. In most cases, the progressive jackpot influences the RTP. So, if a progressive jackpot slot has an RTP of 96%, a part of the RTP is attributed to the jackpot, which means the typical player is playing the game with a much lower RTP. Always check the information section or paytable to get the RTP distribution.
