Free slot: Fire in the Hole

How Fire in the Hole works

Fire in the Hole is a slot machine developed and published by online gaming provider Nolimit City. This slot was launched in 2021 and is available in many online casinos with this provider. Fire in the Hole takes us to a mining operation where treasures are hidden, and it is up to you to find them using the dynamite at your disposal!

This online game offers an original format, with 6 reels that can hold between 3 and 6 symbols. The objective in Fire in the Hole is to make connections of at least 3 identical symbols from left to right, and at each connection the symbols involved disappear to make way for new symbols that will cascade down. Each spin starts in 3x6 format, and as soon as you connect, the game round continues and a new line under the grid is unlocked, up to a maximum of 6 horizontal lines. As soon as there is no more connection, the grid returns to 3x6.

Many original features are present on Fire in the Hole, both in the base game and in the very original free spins that will make this slot extremely attractive. If you like atypical and highly volatile slots, then Fire in the Hole is made for you!

As explained above, there are many features on Fire in the Hole that will enhance your gaming experience. In addition to the connections that can expand the slot, a wild that appears randomly will also allow you to get an extra line and each wild will increase the multiplier by 1. This technology present on Fire in the Hole is called "xBomb".

Some slots are blocked by stones and are therefore inactive. The wild, represented by a detonator, will explode and all adjacent squares and squares blocked by stones will become active and will now contain a symbol.

The Wild Mining function is also available in the base game. This function intervenes when a spin loses but at least 3 identical symbols are still aligned. All the symbols on the grid explode (except wilds and scatters) and disappear to make room for new symbols and a wild one that can potentially help you make connections:

• 3 symbols aligned = 1 wild

• 4 symbols aligned = 2 wilds

• 5 symbols aligned = 3 wilds

The different symbols of Fire in the Hole

Fire in the Hole is composed of 10 symbols appearing in the base game as well as a wild mentioned above and a scatter giving access to free spins. Like many slot machines, this online game has 2 categories of symbols that you will need to connect to win: the classic symbols and the premium symbols.

The first named are the most common and the least rewarding. They are represented by the highest values in a card game, namely 9, 10, Jack, Queen, King and Ace.

Premium symbols are the most difficult to connect but they are the ones with the highest value. They are represented by objects that are usually found in mining operations, among which are :

• the pickaxe

• the rope

• the boots

• the satchel

• the lantern

The different connections in Fire in the Hole

In order to win in Fire in the Hole, you need to connect between 3 and 6 identical symbols from left to right. The longer the connection, the higher the payout. This online game does not have any predefined paylines. In fact, the connections in Fire in the Hole are adjacent, which means that the mere presence of the same symbol on the first 3 reels will be enough to win.

There are up to 729 connection lines at the start of each spin. This number can increase to 46,656 different ways to connect when the grid reaches the maximum set up, which is 6x6.

How the Fire in the Hole bonus works

Fire in the Hole has an unusual bonus feature that will make this slot very attractive. Depending on the number of scatters obtained, the starting grid will be different:

• 3 scatters = 2 lines

• 4 scatters = 3 lines

• 5 scatters = 4 lines

A new horizontal line will be added at the top of the grid and will be represented by a mine train. It will be composed of 6 wagons that will contain different symbols specific to the free spins that will be positioned above each column.

The objective of the bonus is to collect different valuable coins that will cumulate and give you your final win. To do this, as soon as a symbol appears on the grid, it will take the value of the special symbol at the top of that reel. 3 free spins are offered to you and as soon as a new symbol is collected, 3 free spins are again awarded to you. The bonus stops when 3 free spins in a row are lost.

In the Fire in the Hole bonus, there are some special symbols and features that can potentially win you huge sums of money:

• the coin: you win the value written on it (between x1 and x100)

• the multiplier: multiplies the value of all the coins on the roll (between x2 and x25)

• dynamite: will explode between 2 and 4 blocks of stone and give you more squares to get pieces.

• the bag: collects all the pieces present on the roll and frees up space on the column

• the chest: collects all the pieces present on the grid and frees up space on all the rolls

• the dwarf: collects all the pieces of the grid at each spin

A line is present at the very bottom of the slot and contains 6 safes. If a dynamite unlocks one of the chests, then that chest will collect all the symbols from its roll with each spin.

Fire in the Hole offers you the opportunity to purchase the bonus by paying 60, 157 or 500 times your initial bet. This purchase will allow you to start the bonus with 2, 3 or 4 horizontal lines respectively.
