Hottest 666 Demo & Review

Hottest 666 review

Hottest 666 is a neon 5x3 classic with an inventive bonus. When the bonus is triggered (by scatters or bonus buy), a pre-bonus round runs on a three-reel machine that decides the number of free spins, the number of playing fields and the multiplier, each up to 6.

During the pre-bonus, you can buy a respin or a +1 boost for any of the three values, which lets you shape the bonus at a cost. The free spins themselves feature Wild Rain, which sprinkles wilds across the reels. Hitting 666 in the pre-bonus is the dream scenario. BGaming rates it very high volatility with a 6,600x maximum and a 96% RTP. Free spins arrive about once every 150 spins.

Hottest 666 RTP, volatility and max win

RTP: the default return to player is 96.00%, meaning that over a very large number of spins the game is designed to pay back around 96.0 units for every 100 wagered. Some casinos may run a lower configuration; the info screen inside the game shows the exact figure. How RTP works.

Volatility: Hottest 666 is a very high volatility slot. Most sessions will be dominated by small wins and dead spins, with the bulk of its return concentrated in rare bonus rounds. A short session can easily lose its whole budget without a meaningful hit – the demo is the safest way to see how swingy it really is. Volatility explained.

Max win: the maximum payout is 6,600x the stake. What max win really means.
