About Tridentia Slot

Tridentia slot is a jackpot slot game developed by Blueprint Gaming, who are known for their epic fleet of Jackpot King slot games. Tridentia is inspired by the Greek god of the sea, and Poseidon himself may make an appearance on the reels. Played on a five reel, three row setup, with ten paylines, this is a classic slot concept at first glance, but the addition of the huge jackpot plus an epic free spins bonus make this casino game anything but basic.

Visually, Tridentia slot is certainly stunning, with the reels being submerged deep underwater at the bottom of the ocean. Flanked by regal stone pillars, you’ll certainly know you’re in the presence of the ocean’s royalty, and the mythical-themed symbols add that extra element of mystique. The high paying symbols can be very rewarding - land five of Poseidon's golden tridents for 500x your bet. Play Tridentia slot on mobile, desktop or tablet.

Tridentia Slot Special Features

Posedion Expanding Wild
The mighty Poseidon lives up to his reputation in Tridentia slot, possessing not only the ability to substitute for all other symbols (except Bonus), but to expand to cover entire reels as well.

Tridentia Free Games
Land three or more Bonus Scatter symbols on the reels to trigger the Free Games bonus. Up to twelve free spins will be awarded. Each time one or more Expanding Wild symbols appear on reels 2, 3 or 4, the symbol upgrade feature will come into play, as Poseidon will upgrade a symbol at random, turning it into the next highest-paying symbol. This increases the value of any potential line wins that may be achieved. The Free Games bonus can also be retriggered if one to three Scatter symbols are landed.

Jackpot King
Tridentia slot, like many Blueprint titles, is plugged into the lucrative Jackpot King, a progressive jackpot that can be triggered by any spin at any stake. Look out for golden crowns, because if five are landed on the reels, the Jackpot King feature will commence. You’ll then be tasked with making your way as far up the Cash Trail as possible, for the chance to spin the Wheel King. This is where the game really makes a splash, as the Wheel King awards colossal multipliers or even the progressive jackpot sum.
