How We Test the Chance of Winning
As previously discussed, casinos are allowed to change the odds of winning on many of the top games — and GrandWin has lowered those odds a lot.
They can do this by changing the return-to-player or RTP. If an RTP is lower, it gets harder for you to win — and the more the casino keeps.
We run our test by reviewing the same 10 slots at every casino and seeing how their RTP compares to the highest return possible for each game.
Check out the full breakdown just below. Swipe to see how competing casinos rank.
When you swipe through, it’s clear how big the gap is between GrandWin and the other casinos.
While playing slots the game’s RTP setting is the factor that will have the most impact on your odds of winning.
If you are looking for casinos that give you the best odds of winning you can see them at the top of our list of the best casinos.
If you don’t know this, You WILL lose:
Almost all slots have various RTP option.
Basically the two versions might look exactly the same but the winning chances aren’t the same so one can actually be more profitable.
Like Gates of Olympus from Pragmatic Play. You’ll find an option with 96.50% RTP as well as one with 94.50% RTP.
The variation may not stand out but in reality it actually affects your odds.
What really matters is getting a handle on the edge the casino holds at that casino.
The House Edge is:
100 % – 96.50 % = 3.50 % for the good version.
And:
100 % – 94.50 % = 5.50 % for the bad version.
What that shows is that every time you spin (on average) 3.50% goes to the casino in the high-RTP version and in the worse RTP version, 5.50% goes to the casino.
If you break it down a $100 bankroll gets you about 2,857 spins at 3.5 cents and 1,818 spins with the lower RTP setting. What that gets you is roughly 1,000 spins if you go with the high vs low RTP — and a lot of extra chances to win big on Gates of Olympus.
