One of the four initial elements, fire may be both fascinating and dangerous. There's nothing to be scared of, though, as in these slots fire is something that can help you trigger some nice wins.
You are likely to find fire symbols in virtually any kind of slots, including the classic ones, which are also sometimes based on fire. However, most of those symbols appear in video slots themed around some abstract things like the elements, the dark magic, or the devils. Sometimes, fire is also featured in slots based on nature: most likely, you are going to see them in volcano themed slots.
Anyway, fire is always good for slot players, as it is usually used as a high paying symbol and sometimes also clears up the reel screen to trigger a respin or two. Bonuses featuring fire may be particularly interesting and exciting, as besides triggering nice cash wins, fire symbols will also add some good animations and effects to the gameplay.
