Champion of the Underworld Review

Last Update: 29.09.2022. Author: SlotCatalog.

Apparently, Yggdrasil is starting an ‘of the Underworld’ slot series, and Champion of the Underworld seems to be the first installment. They have a few related releases from before though, but not with that exact wording in the title. In addition to Wild Fights at random times in the base game, you also get a dynamic grid experience via the Gigablox symbols.

They don’t really change the grid though, as they count as 1x1 sized symbols when part of anything. The 6x4 reels setup with 4,096 win ways is something this developer does well, and the cartoonish underworld visuals displays a massive arena where different ungodly creatures duke it out with Hades himself. The 10,000x potential is solid, and this is a game well worth checking out.

Champion of the Underworld Slot Features

You get Gigablox symbols up to size 4x4 on each spin, and the Gigablox symbols are broken down to regular 1x1-sized symbols if part of a win. The 4 demon-like premium symbols pay between 1 and 2 x your stake for 6 of a kind wins, and the Skull Wild steps in for pay symbols to help complete wins.

You get the Wild Fight feature at random times in the base game, and you will then see Hades fight any premium symbol in sight. The symbols turn wild if Hades wins, and this includes Gigablox symbols.

You need at least 5 scatters on the same spin to trigger the Bonus Round, and scatters can also come in the form of Gigablox. Each triggering scatter awards +1 free spin, and you can gamble for up to 20 free spins if you wish. The gamble is a sword pick game that comes with 2 tiers, and you risk losing the whole bonus round if you lose.

You get the Wild Fight feature on every bonus round spin, and the win multiplier counter increases by +1 each time Hades wins. You need 9 symbols transformed to wilds to get an x2 multiplier, and 11 more to get to x3. Further, you need 13, 15 and 17 more transformations to get an x5, x10 and x25 win multiplier, respectively. You also get +2 extra spins per upgrade.

On a final note, non-UK players and anyone eligible, can take advantage of the Bonus Buy option. You can pay 90x your stake for 5 free spins, or 1,000x your stake to get the maximum of 20 starting free spins.

The 200 Spins Champion of the Underworld Slot Experience

You get to see a few base game wins, before we purchase the top-tier bonus round at 0:50 into the 12-minute highlights video. As you probably understand, the feature went on for quite a while, and you can see for yourself how we fared by hitting the play button below.

Review Summary

We like the idea and concept this Yggdrasil release is built around, as it’s not too hard to imagine nasty creatures in the underworld duking it out tournament style for entertainment and hierarchy-climbing. The execution is pretty solid as well, and Champion of the Underworld comes with engaging visuals and scary looking multi-eyed monsters.

The soundtrack became a bit too repetitive after a while though, but Gigablox and random Wild Fights keeps the base game varied and interesting. The bonus round varies a lot as well, and starting with a larger number of spins is a huge advantage when it comes to climbing the multiplier ladder. The 10,000x potential is decent enough, and overall Champion of the Underworld is a decent installment in the Gigablox/Wild Fight range.

Pros

  • Up to 4x4-sized Gigablox
  • Wild Fights at random times
  • FS w/ increasing wild fights multiplier
  • Win up to 10,000x your stake

Cons

  • Adjustable RTP ranges

Monsters vs Gigablox - is inspired by the 80s video game, Rampage, and this Hot Rise Games release comes with a 6x6 grid with 50 win ways. Gigablox up to size 6x6 can appear in all stages, and you get a chosen rampage monster wild in the bonus round. The max win is 3,116x your stake.

Champion of the Underworld SlotRank Calculation

SlotRank - is the rank of the game popularity in the specific market. We are calculating SlotRank based on the gathered data from the online casinos. Daily our crawling system scans thousands of casino sites. From each casino sites we are getting list of games, lobbies screenshot, and list of games in the lobby. Important parameter of games popularity is average games position in the casinos lobby. To calculate Average position in the casinos lobby (APL) for Champion of the Underworld, we are using formula:

APL i = (4i + (281i - 1i) * 151 i) / 281i = 150.477

Where:
281 - quantity of valuable casinos with high weight in the United Kingdom. (Each casino gets weight. Casino weight is relevant to estimation of Internet traffic)
4 - Summa of positions in the casinos lobby
1 - Quantity of casinos that put game into the lobby
151 - We put size of casino lobby as 150 games. 151 - means that game is not in the lobby.

For the SlotRank calculation we are using SlotRank Value (SRV) parameter. SRV is sum of points that game gets for positions in the casinos lobby + points for presence in casinos + very minor value for game release date.

SRV i = 747.244i + (13.021 / 5000)i + ((0.1 * 19264)i / (5000 * 36500)i) = 75.264

SlotRank - is position in the game list sorted by SlotRank Value. Points that Champion of the Underworld gets for positioning in lobby:
747.244 = SUM ((151- Lobby Position)* CRV)
CRV (Casino Rank Value). CRV - is casino weight coefficient from 0.1 to 1 that gets each casino according to their traffic estimation.
Lobby Position - position in the casino lobby. We are measuring position for TOP 150 games. Highest position means that game placed on top left position in the casino lobby.
