But truly random systems will be volatile. In terms of slot machine design, that means long dry periods of no wins (big or small) at all. If you talk to slot designers, the word "volatile" is used about every 30 seconds. The virtual reel and near-miss concepts are designed to give the appearance of a less volatile machine, which converts into a player staying on the machine longer. TLDR: fake near misses hide the actual randomness of the reward system.
