Fire Queen is developed by WMS and is based on the Double Money Burst engine. The reels are arranged in three symbol blocks; the main reel set has the 3×6 layout, and both the mini reels feature a 2×2 configuration. With 100 fixed paylines that run across the reels in different patterns and manners, the slot provides potentially big wins, and every spin that you make can produce multiple winning combos at a time. A line bet is the only user-configurable betting option that lies in the range between $0.01 and $1 (per two lines); therefore, a total bet can vary between $0.5 and $100 per spin.

Bonus features

The slot has a wild symbol that appears stacked. This means that the wild may form a long vertical array of six, seven or more symbols on top of each other and occupy an entire reel, which usually results in one or more winning combinations. Besides, hitting 5 wilds on a payline awards up to $800. If the wild appears in any position on a small reel set, it will duplicate itself to the same position on the other small reel set.

A free spin feature can be activated in two different ways. The first, and simpler, method is to get four identical symbols on a mini reel or three Feature symbols scattered in any position. If this is the case, you are awarded 5 initial free spins. Another method, which will earn you 20 initial free spins plus the maximum of $10,000, is to get four matching symbols on a mini reel and three scattered Feature symbols on the main reel. What is more, every Feature symbol that comes in excess of what is required to trigger the free spins, gives you five extra spins complementary to the initial amount.
