Why is RTP an important factor to consider?

After reviewing and trying out a variety ofgambling sites, we feel most NZ casinos will refer to RTP as payout.The payout % is displayed in each slot machine pay table. If you are considering one game over another, we suggest you go for the one with the higher %, as this is the game that will be more rewarding to you.

How is a slot RTP calculated?

Now that we have established what RTP means to you and how to make the most of it, it is time to give you some background on how it is calculated. When a game development company creates a new video slot, RNG mechanisms are incorporated within the game.The RNG refers to the Random Number Generator that the game will deploy to reward fairness. Basically, RNG is there to ensure the game is not rigged.

Once the RNG factor is incorporated, the developer has a Gambling License and Legal obligation to test the game for fairness. This process is completed by an external body called eCorga. The company tests out the game to ensure the randomness factor is working correctly, whilst also runs algorithm testing to determine the game payouts you nget.

When the process is complete, the RTP % is added to the slot game’s paytable, with the game ready to be launched in the gambling markets.Whilst eCorga is one of the biggest RNG testing firms in the gambling business, other testing firms include iTech Labs and BMM.

Where do I find a slot RTP %?

This is a question that we get asked alot. Normally a slot RTP % is either a fixed amount of a ranging amount eg. 92-96%. It would be ideal for you to check out the slot payouts prior to hitting that spin button. A difference is RTP offers you a different gaming experience, hence finding the best RTP% is crucial for your gameplay.

Head over to the slot paytable to be able to view the game’s RTP %. Whilst 99% of games have the % visible, some might not. In that case, we suggest that you reach out to the site’s customer support team, who will gladly assist you.

Can a game RTP % change?

If you are having an unlucky day at a slot game, you might want to consider finding another one with a better payout. Many gamblers have the illusion that a game RTP changes from one day to another, the answer is simply: No, it does not.

Once a game developer creates the games, with specific algorithms and specific features, there is no feasible way to alter the game’s RTP. Possible game new releases might have different RTPs, e.g Book of Dead slot series, yet the original game release will keep its game RTP forever.

Volatility vs. Game RTP: What is the difference?

Game volatility and game RTP are sometimes intertwined in our minds, hence let’s give you some background to both. WE already discussed how RTP is the return to player amount a slot machine offers you. The factor is based on testing, game audits and also external bodies regulating the game.

Game volatility is a totally different ballgame, with the factor taking into account the level of risk you are willing to take when playing. A high volatility slot machineis a game that offers lower payout rates, yet when a win is secured, it could be quite chunky. Low volatility slots are games that will offer you wins at a frequent pace, yet the winning pots are much smaller.

After playing endless online games, we find that both volatility and RTP % are important factors to consider. Both Volatilityand win rate potentials are always a personal game choice, but higher RTP is always a must.

Things to consider when choosing your next casino game

If your goal is winning at online casino games, there are some elements to keep in mind. Your game choice will determine your gameplay, and in return will offer you the gaming experience based on your game choices. Here are some points to keep in mind:

Game RTP % matters

We have already established that the higher the game RTP %, the bigger your wins will be. High RTP% slot games offer higher payouts, hence better chances of your walking away a winner. Choose games with higher RTP % for better winning chances.

Low vs. High Volatility

You would need to decide if you want small wins at a steady pace, or chinkier staggered wins. Game volatility is also a feature to keep in mind, especially when you are wagering big deposits.

Try out the Game via Demo

Most NZ casinos offer you the chance to try out games for free. Playing with fictitious money, and spinning the reels will give you a feel of the game. This is when you can also establish the game RTP, and how frequent wins come your way.

Bonus Rounds and Promotions

We feel that casino promotions are a viable way for you to snag free spins and extra play money. Prior to settling on a game, check out if any game promos are available Eg. Deposit 10 NZ$ and get 20 free spins on the reels of Racatoonz slot. Bonus money and spins are a great way for you to double up on your deposit money.

Conclusion

The world of online casinos is a lucrative one, with many online casino games available at our fingertips. One developer competes with the next one to launch the next slot sensation. Sometimes, we are even spoilt for choice, enjoying 3 new slots a month. But what makes slot A worthy more of Slot B? Graphics, game features, bonus rounds, volatility, and ultimately RTP%. Choosing the right slot game with the best RTP% is a solid way for you to enjoy gambling and winning at Kiwi online casinos.
