How to test the Chance of Winning?

As described earlier, casinos are allowed to change your chance of winning on some of the top games — and GrandWin Casino has lowered your odds a lot.

They're able to do this by tweaking a setting called the "return-to-player" (RTP). The lower the RTP, your odds of winning are lower — while the casino makes more.

We measure this by looking at the same 10 popular games at each casino and comparing their return-to-player settings against the highest RTP offered.

See the full results listed below. Swipe to the right to check out how the others fared.

With a quick swipe, you'll quickly see how big the gap is between GrandWin Casino and the other casinos.

While playing slots the assigned RTP is the feature that can have the biggest impact on your chance of winning.

If you're looking for casinos that give you the best odds of winning you'll fortunately find them inside our list of today's top online casinos.

If you don’t know this,You WILL lose:

Most online slots often have different RTP versions.

In other words each version appear to be no different but the winning chances aren’t the same so one can actually be more profitable.

Take a game like Gates of Olympus. The game has a 96.50% RTP version along with a lower one at 94.50%.

That tiny difference doesn’t seem like a big deal yet it changes things.

What’s most important is checking what the House Edge is 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.

To break it down on an average spin 3.50% goes to the casino on the version with better odds but in the worse RTP version, 5.50% goes to the casino.

If you break it down 100 translates to roughly 2,857 spins on the high RTP setting versus 1,818 spins with the lower RTP setting. It comes out to around 1,000 more spins between the two versions — that’s a lot of extra chances to win big on Gates of Olympus.
