What Are RNGs in Free Slots and How Do They Work?

RNG means Random Number Generator. It is a technology that produces unpredictable outcomes for every slot spin. Casinos use RNGs in slot games to guarantee fair & unbiased outcomes. In other words, the outcomes are not predetermined or manipulated in any way.

In the case of free demo slots, gamblers experience the same game volatility, mechanics, and win potential, but without financial risk. Audit agencies like eCOGRA and iTech Labs test the RNGs of leading developers like NetEnt and Playtech to confirm provably fair games.
