Immortal Romance December 7, 2018 Bingouncle Immortal Romance is one of the most popular online slot games ever to be produced by global software giant, Microgaming. Its free spins bonus uses a similar game mechanic to Thunderstruck II except, instead of the Great Hall of Spins, you have The Chamber of Spins. This means that as you make progress in the game and, therefore, continue to trigger the free spins bonus, more options become available to you. And, once all four options are unlocked, each time that the feature is activated, you get to choose which of the four character’s bonus you wish to play. For example, Michael’s special feature is Rolling Reels while Troy’s Bonus uses Vampire Bats to add win multipliers of up to 6x.
