Champion of the Underworld

An underworld arena forms the stage for Champion of the Underworld, Yggdrasil Gaming's 6-reel, 4-row slot, complete with ghostly onlookers seated beneath stone columns, drifting turquoise flame effects and piles of skulls scattered around the panel. The presentation leans dark and theatrical throughout.

Wins land across 4,096 ways whenever three or more matching symbols appear on adjacent reels from the first one, and the reels themselves can merge on any spin to form oversized GigaBlox symbols ranging from 2x2 up to 4x4 in size, each one broken back down into ordinary symbols for the purposes of paying out. Eight symbols make up the pay table: four card suits pay 0.5 times the stake for six of a kind, and four creature symbols pay 1 to 2 times the stake at the same six-symbol count. A skull acts as the wild and substitutes for any other symbol on the board.

Wild Fight can fire at random in both the base game and free spins, pitting Hades against every high-paying symbol currently in view; each one he beats turns wild, GigaBlox symbols included. Five or more scatters in view — whether standard size or GigaBlox — trigger the free-spin round, with each qualifying scatter worth one spin. On entry, players below 20 total spins can gamble for more by drawing one of ten swords, a golden sword adding spins and a broken one forfeiting the round entirely, across either of two available gamble levels.

Inside free spins, Wild Fight fires on every single spin, and each symbol it turns wild also advances a multiplier ladder: nine transformations reach x2, another eleven push it to x3, thirteen more to x5, fifteen more to x10, and a final seventeen to x25, with two extra free spins awarded at every step along the way. A direct buy-in costs 90 times the stake for five free spins, or 1,000 times the stake for twenty.

Bets span 0.20 to 100 a spin. High volatility applies throughout, per Yggdrasil Gaming's own rating, and the maximum win tops out at 10,000 times the stake. RTP defaults to 96%, with three lower configurations down to 86%, and hit frequency lands at 25.76%. The combination of random Wild Fight hits and a climbing free-spin multiplier means big results tend to arrive in a single extended bonus round rather than trickling in across the base game.
