So my question is:
(1) Is there a logical reason behind why slots make x10 feel easier to achieve?
It looks easier
but, it is not actually that easy. But it is possible because of the way it is designed. You have shorter time to wait for your spin result and without analysis, you go on another spin. You might be lucky being consistent to get x10, the logical reason there is the luck that has been randomly configured on the machine that generates combinations of symbols/figures. So you can go on it 10 times on the spot and you are successful but this is most likely not the same with sports. If you have a bet on football, it takes 90 minutes to FT and most games on your bet won't start same time (for parley). Except you go live or you bet on visual soccer but by any means, you still need analysis and the time of
playerplay is still longer than a slot spin.
