Like the Spider-Man: Attack of The Green Goblin slot, Fantastic Four relies on the original comic books as its source material rather than the most recent Fantastic Four movie or the film of the same name released in 2005.
That's probably for the best, since the 2023 Fantastic Four was almost universally panned by critics and the original is over a decade old. The game instead uses photorealistic 3D renderings of the characters, and they look great...even though the Human Torch's reel icon looks angry all the time.
With the exception of a little jingle during the intro and after wins, Fantastic Four is completely silent. A rousing superhero movie style score might have helped to establish a bit of ambience but, if it really bothers you, you could always find the movie soundtrack on Spotify while you play!
All the graphics looks nice, although it has to be said that the game will probably start to look a bit dated in years to come. Also, the wild 4 icon looks way too much like the A symbol, which can be confusing when you're waiting to see if you've won or not.
