About the Game

Champion of the Underworld is a Video Slot with 6 reels, 4 rows, and 4096 ways, paying from left to right. The game has 4 high symbols and 4 low symbols that may win if three or more are lined up on a payline, beginning from the leftmost position. There is a Free Spin symbol that awards Free Spins when 5+ land anywhere on the reels in the base game. There is also a wild symbol that only appears from the Wild Fight feature and substitutes all regular symbols.

Gigablox Feature

Gigablox are oversized symbols on the reels that function like individual symbols in a 2x2 to 4x4 formation. Free Spin symbols can also land as Gigablox.

Wild Fight

During any spin in the Base Game, Hades can fight all high symbols to convert them into wilds. If he wins the fight, that symbol turns into a wild for that turn. Gigablox symbols also have a chance to be converted. In Free Spins mode, Hades fights each spin and each symbol that turns wild increases the multiplier counter.

Free Spins

Land 5+ Free Spin symbols to award a corresponding amount of Free Spins. Each Free Spin symbol that lands on the reels in Free Spins adds 1 additional Free Spin. Free Spins have a multiplier counter. Each time Hades turns a high symbol into a wild, the multiplier counter is increased by 1. Turn the first 9 symbols into wilds to get an x2 multiplier and 2 extra Free Spins. Turn the next 11 symbols into wilds to get an x3 multiplier and 2 extra Free Spins. Turn the next 13 symbols into wilds to get an x5 multiplier and an extra 2 Free Spins. Turn the next 15 symbols into wilds to get an x10 multiplier and an extra 2 Free Spins. Turn the next 17 symbols into wilds to get an x25 multiplier and an extra 2 Free Spins! x25 is the maximum multiplier, after that, the counter will stop. The multiplier applies to each spin individually. Gigablox that are converted into wilds are counted by their size: a 2x2 Gigablox wild counts as 4 wild symbols towards the counter. The multiplier counter for each level is visible in the orb. Free Spins are played with the same 4096 ways and bet as the activating spin.

Gamble

When entering the Free Spins Mode, players can gamble for more Free Spins, unless they already have the maximum 20 Free Spins. Players can either gamble for a lower amount of extra Free Spins with a higher chance of success or for more Free Spins with a lower chance of success. The Gamble feature is presented as a Drawing Swords minigame. The players must choose a sword - if they choose a sword with a golden tip, the Gamble is won. If they draw a broken sword, the Gamble is lost.

How to Calculate Wins with Ways

  • To calculate the total Ways win, add all the symbol wins together.
  • To calculate a single symbol win, count the number of consecutive reels that contain the symbol, starting from the left.
  • If the number of consecutive reels containing the symbol is 3 or greater counting from the left, find the corresponding win amount in the dynamic paytable.
  • If any of the reels contain more than 1 instance of the symbols, the win will be multiplied. Multiply the number of symbols on each of the reels to get the final multiplier. For example: if the first reel contains 2 symbols, the second reel has 3 symbols and the third reel has 2 symbols, the total multiplier is counted as follows: 2*3*2=12 (total multiplier).
  • The above doesn’t include any Free Spin symbols which pay scattered.
  • Way Wins are summed together after the spin.
