That kind of pattern makes me wonder, are these games secretly rigged, or is this just how slots work because of the RTP (return to player), which is usually around 97% or even lower?
When you're playing slot, just have it at the back of your mind that you're taking risk, because you cant afford to make any progress without going through the normal and usual procedures, which is in the attempt of trying your luck playing it, this is not what you may have to develop any skill for before been able to play it, slot is ore of what we can play even as a beginner and catch the fun and forget about RTP being rigged or not, because some are wining big by luck.
