@Kelvin It really depends on what games you are playing. As I mentioned before, for example, hacksaw is so volatile, which basically means that the chance of hitting big wins is higher, but it comes with the cost of fewer wins in general. Don’t let RTP (return to player) fool you. It can be exactly the same but still have a very different gaming experience. 

Good tip for this! In pragmatics and few other providers, when you open the game you can see the volatility scale from 1-5. The more volatile, the less wins and bonuses BUT can pay a lot more when it hits.
