Introduction
From its multiple integrated bonuses to its win multipliers, free spins and decent 7,500 top win, this is a seriously impressive slot with a lot to offer. Nucleus Gaming slots have quite the reputation for immersive playing experiences, so let’s explore in a bit more depth precisely what is on offer here.
Theme, graphics & soundtrack
Although Joker Gemferno doesn’t have the most intricately designed layout we have ever seen, it still delivers just enough to hold the interest of even the most seasoned slot game players. If you are looking for a classic slot with a contemporary twist and don’t mind having a mildly scary joker companion throughout, Joker Gemferno is practically tailor-made for you.
Players will find all the classic fruit symbols here, which have had a bit of a 21st-century upgrade. Additionally, players will see a selection of faceted gems on the paytable, alongside other symbols including red Xs and gold stars. The animations are seamless and the sound effects, whilst basic, do a good job of enhancing the in-game experience.
Joker Gemferno RTP and variance
Unfortunately, both the RTP (return to player) percentage and variance of Joker Gemferno are unknown.
How to play Joker Gemferno

- For players who want to customise their in-play experience, the speaker icon to the left of the ‘i’ icon will mute the soundtrack and sound effects.
- Setting the in-play stake is simple. First, use the - and + toggle buttons on either side of the line box to select the number of lines that should be in play; next, use the - and + toggle buttons on either side of the bet box in accordance with your budget.
- All that remains is to hit the spin button to start enjoying the game responsibly.
