In slots especially, RTP percentages are usually displayed and these can range in the mid to high 90s.
RTP is not to be confused with volatility.
It is typically given with slots.
RTP in Slots
Calculating RTP in slots is not a straightforward process.
RTP on specific slots may vary between casinos.
You may find a game that has a higher RTP in one online casino and lower in the other.
This is because when slots are supplied to operators, they can change the software to meet their standards.
This will not change the gameplay in any way at all.
Of course, in card games there are plenty of aspects that can change RTP.
These will all change the house edge and thus change the RTP percentage of each game.
What these actually do is give you the best chance of winning by statistics.
Roulette
Of course, there are plenty of table games where there is no decision-making.
You simply stake your bet and then hope for the best each round.
Roulette is a great example as it is very straightforward.
Here are some examples of the house edge in popular formats of roulette.
To keep things simple, the calculations are only done with a single and splits bet in each case.
European Roulette
There are 37 segments in European roulette, numbered 1 through 36 and including 0.
All the segments are coloured red or black apart from the 0 which is green.
These are the numbers 1 through 36, 0, and 00.
Of course, this does not mean that a game is better if it has a higher RTP.
At the end of the day, you should always remember that anything can happen in games of chance.
That is what makes them so attractive and exhilarating to play.
