To make the best out of high-paying casinos, it’s crucial to understand payout percentages. These will help you grasp how fair or profitable playing at a particular casino will be. Let's take a look at the basics.

What Is RTP?

The return to player rate or RTP is the percentage of long-term returns on money wagered at a casino. This number represents the average RTP for the whole game collection. As every game offers an RTP of its own, which is determined after millions of rounds, short-term outcomes may vary. The average payout rate at a profitable casino should be higher than the industry benchmark of 96%. At the highest-paying online casino the RTP will fluctuate anywhere between 98% and 99%. 

Calculating the RTP Rate

To understand RTP over a long session, let's use a total deposit of NZ$1,000 as an example. At the best payout online casino in NZ an overall RTP will be around 97%. From your total bet of NZ$1,000, on average, you can expect back NZ$970. Use this simple formula to calculate it – NZ$1,000 x 0.97 = NZ$970. 

House Edge

The house edge represents the casino's mathematical advantage over the player that remains if you subtract RTP from 100%. For instance, if the casino's RTP is 97%, the house advantage is 3% (100% - 97% = 3%). The best casinos are those where the house edge number is not higher than 2%-6%.

Our team went through over 70 different brands to select our top five highest paying online casinos in NZ, including the most popular Tonybet Casino and Spinfever Casino.

New Zealand players have witnessed a number of notable wins over the years. In 2013, one NZ player won $100,000 playing roulette, and in the same year another casino customer claimed a $943,971 jackpot on Games Global’s (formerly Microgaming) Mega Moolah slot.

Mega Moolah has remained popular with New Zealand players. In 2016, one more participant won a NZ$10 million jackpot in the game. The win followed an initial NZ$1,500 payout, after which the player continued playing and eventually triggered the main jackpot.
