Demo Play: The demo mode is a perfect feature for players who want to try out a new game. This feature allows punters to play a game without spending real cash, and that’s because the demo game of a slot offers the same gameplay as the main game.

Paytable: This feature displays the value of all game symbols and allows punters to plan their games better.

Wild Symbol: The wild in the Crystal Furnace casino game is depicted by a hammer. This hammer wild can substitute for other symbols on the reels and expand to create more winning combinations on the reels. 

Bonus Features

Unfortunately, Crystal Furnace doesn’t offer much in the way of special features. There are no scatter symbols either, just the wild symbols.

Nevertheless, its sole feature, which is described below, also makes for fascinating gameplay:

Expanding Wild Respin: This feature is triggered when you land one or more wild hammer symbols on the reels. Although they only appear on reels 2, 3 and 4, wild symbols can lead to more winning combinations. That’s because as they appear, they become expanding wilds, expanding to cover that entire reel.

As the expanding wild covers a reel, the respin feature is activated, causing other reels to respin once. Each single respin leads to the formation of more winning combinations, and an extra spin is awarded for each wild that appears in that round.
