How does train movement affect gameplay or fairness?
It doesn’t influence the fairness in the slightest. The game’s Random Number Generator and the end result are all determined on the casino’s protected servers. Your phone is essentially a fancy screen. The train’s movement might make you tap a control by mistake, so using a ‘spin confirm’ setting can be a smart move. The result is determined the moment you initiate the spin, even if your signal drops a second later.
