I’ve played Fortune Gems 500, and I can confirm that JILI increased the volatility compared to the original version. It's quite noticeable if you’re familiar with the first game. You can find the
jili slots section. The description provides general information but doesn't list a specific volatility figure. In practice, I’d characterize Fortune Gems 500 as having medium-to-high volatility. The base game can be pretty quiet, so you need patience to wait for a decent bonus round. However, when it hits with good, high-value symbols, the payout can be substantial. The "500" in the name refers to the maximum multiplier on the base deposit, which gives you an idea of the potential payout. If you liked the rhythm of the original, approach the "500" version with a larger bankroll, as dry spells can last longer.
