PALM SPRINGS, Calif. -- Brian Christopher is a gaming influencer with massive followings on his YouTube channel and Facebook page. When Gaming Arts, a gaming machine manufacturer, reached out to Brian to design his own slot machine, he couldn't pass up the offer.

Interesting question- slot machines are actually based on a degree of randomness in each individual play, but the payouts when those random events produce a winning combination are controlled to ensure that only a certain percentage of money played is paid back. Typically in the high 90% range.
