Gigablox Symbols

The Champions of the Underworld online slot has a Gigablox symbol which can go up to a 4x4 size on every single spin. 

Should the Gigablox symbols form part of a winning combination, they will be broken down into 1x1 average-sized symbols before being counted.

Wild Fight

This feature can trigger randomly during the bonus and the base game. When it is active, Hades will fight any high-value symbol in view, and if he wins, the high-value symbol he was fighting turns into a wild symbol, including Gigablox symbols.

Free Spins Feature

The Free Spins feature is the bonus round; you trigger it by landing 5 or more scatter symbols.  

The number of Free Spins you receive will be determined by the number of scatter symbols that triggered the game, with each scatter symbol worth 1 Free Spin. 

So, if the bonus game is triggered by 5 scatter symbols, you will receive 5 Free Spins. If your Free Spins are less than 20, you have the option to gamble for more.

If you choose to gamble, the game will present you with a collection of 10 swords. Pick a sword to reveal whether it is a golden sword, in which case you win the gamble. However, you lose all of your Free Spins if you pick a broken sword.

The Free Spins also have a win multiplier. For example, if Hades transforms a symbol into a wild, your multiplier will increase by 1+. 

  • 9 Transformed symbols reward a 2x multiplier
  • 11 transformed symbols award a 3x multiplier
  • 13 transformed symbols award a 5x multiplier.
  • 15 transformed symbols reward a 10x multiplier
  • 17 transformed symbols reward a 25x multiplier.

The progress is not stackable, so after transforming 9 symbols and receiving a 2x multiplier, you then have to transform 11 symbols to receive the 3x multiplier, instead of simply landing 2 more.

Additionally, these symbol transformation milestones award 2 extra Free Spins.

Champion of the Underworld RTP

Return To Player (RTP): 96.0%

The RTP is a theoretical value and is shown as a percentage. It’s used to describe the percentage of money wagered a particular casino game may pay back to players over a certain period of time.

For example, if a game had a RTP of 92%, in theory, this would mean that for every £100 wagered, the game could return £92 back to players in potential winnings. However, it is important to note that winnings are completely random, and players are not guaranteed to receive this.
