Free slot: Hellcatraz

How Hellcatraz works

Hellcatraz is a unique slot machine in the online casino world. Indeed, mixing the graphics of the video games of the 1990s and an original soundtrack, this slot is very appealing to players. In a setting depicting Alcatraz, the most famous prison in the United States, you can walk away with the jackpot. In fact, this Relax Gaming slot machine can win you up to 51,840 times your starting bet.

Hellcatraz is a large-format machine since it is composed of 6 vertical columns and 6 horizontal rows. Free spins can be obtained on this slot machine which is also packed with features for your paid games. It is a cascading slot machine, which means that every time you make a connection, the slot machine makes the symbols that connect disappear and new ones appear. The game round ends only when no connection is made.

When you arrive at the Hellcatraz Slot Machine, you have a choice of two game modes: "mixed mystery symbols" or "lockdown mystery symbols".

The "mixed mystery symbols" is the less volatile of the two game modes. With each new round, brown squares will appear on the screen with numbers inside. The number can be between 1 and 5. With each connection made during a game round, the number inside each square will drop down from 1, and when it reaches 0, a mystery symbol will be revealed.

The second game mode is the "lockdown mystery symbols". The latter is the more volatile of the two. As in the previous mode, numbers will appear in each round of the game. But unlike the other game mode, each square that appears will have the same number. Therefore, if all the connections necessary to reveal the mystery symbol are made, you have a good chance of winning the jackpot.

The different symbols of Hellcatraz

Hellcatraz is a slot machine that contains two premium symbols. They pay the most on this slot machine.

• The prison guard

• The prisoner

The starting bet for the value of each symbol is €0.10.

In addition to two premium symbols, you also have 7 other symbols that pay less.

• The shark

• The guard's badge

• Handcuffs

• The star

• The heart

• The four-leaf clover

• The purple diamond

Hellcatraz is a slot machine that also contains a wild symbol. The wild symbol replaces all the symbols on the slot machine, but has no value. Its value will change depending on which symbol it connects.

The different connections of Hellcatraz

Hellcatraz is a slot machine that does not contain any connection lines. The connections on this slot machine are made only when at least one symbol appears in the first three columns. The connections only work from left to right, as you can see in the following screen. The more a symbol appears on the starting grid, the more money you will earn on the connection.

Hellcatraz contains 46,656 different payment lines.

How the Hellcatraz bonus works

Relax Gaming is a slots creator who loves long bonuses. In fact, to get the bonus on Hellcatraz, you will need to have accumulated 2,000 keys during all your sessions on this slot machine, just like on Marching Legions. Whichever mode you choose to play in the first place, you will need to accumulate 2,000 keys.

As soon as you get 2,000 keys, you are entitled to 5 free spins. As in the base game, squares will appear at each turn to reveal a symbol. However, they come directly with the number "0", which means that you don't have to make any connections for the symbol to be revealed.

On Hellcatraz it is possible to get additional free rides. In addition to the boxes with the number "0", other boxes with the number "2" may appear. If you make two connections in one round, each square with the number "2" will give you an extra round.

If you don't want to "farmer" the bonus on Hellcatraz, you can always buy it. Indeed, the "buy bonus" option is available on this slot machine. Unlike many slots where the purchase costs on average 100 times your initial bet, on Hellcatraz it will cost 200 times your initial bet.
