How to test the Chance of Winning?

As described earlier, casinos can manipulate the odds of winning on almost all slots — and Cosmicslot Casino has lowered your odds a lot.

They do it by changing what's known as the return-to-player or RTP. When RTP is lower, your odds of winning drop — while the casino makes more.

We measure this by reviewing the same 10 popular games at each online casino and comparing their RTP settings with the top available RTP for each game.

Look at what we found below. Swipe to the right to check out how other online casinos did.

If you swiped through, you can see how big the gap is between Cosmicslot Casino and the best casinos.

If you play slots the configured RTP setting is the thing that will have the most impact on your odds of winning.

If you want to spend money at casinos offering you the best odds you can see them in our list of the [CASINO-TOPLIST-PAGE "top-rated online casinos".

If you don’t know this,You WILL lose:

Most virtual slots offer different RTP versions.

Basically what you see on screen show no visible difference but one is more generous meaning your chances are better with one.

Like Pragmatic Play’s Gates of Olympus. It comes with one version of 96.50% RTP plus a 94.50% RTP version.

The change in RTP could look minor but in reality it changes things.

The key thing is knowing what the House Edge is for the slot.

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 with every bet (on average) the house edge is 3.50% on the good one but you lose 5.50% on the bad version.

If you run the numbers that same $100 would give you 2,857 spins with the better edge versus 1,818 spins with the lower RTP setting. What that gets you is a difference of nearly 1,000 spins if you play the good vs the bad RTP version — and with that way more shots at a big win on Gates of Olympus.
