Nitropolis 4 Slot Conclusion

If you enjoy animal-themed slots that offer immersive and rewarding gameplay, Nitropolis 4 slot is the ideal choice.

Nonetheless, exploring this version and discovering its new additions is fascinating, especially for those who have been playing the other versions in the Nitropolis series.

So what is different in Nitropolis 4? Well, firstly, this version takes place in a different location, on an oil rig of sorts, where the team is on a mission to search for riches under the ocean. While the gang is the same in all versions of the Nitropolis series, ELK Studios has included a new bonus feature; the nitro multiplier.

If you are lucky enough, this feature randomly triggers multipliers of up to x12, which can combine with other multipliers available in that round, leading to massive potential wins. Another unique feature of this slot is its x50,000 max win, an upgrade from the previous x10,000 max win in Nitropolis 3.

Familiarize yourself with this new version without wagering any cash on the demo mode. Available on or any other website that offers ELK Studios games, the free Nitropolis 4 test mode enables you to learn the ropes before you start playing the real money version. With a fixed 94% RTP, decent base game, generous bonus game features, intriguing visuals, and 5 bonus buy options, it is clear why this slot is steadily growing in popularity.
