If you're brave enough to return to the depths of the Earth, take your chance to spin the reels of Champion of the Underworld. In this next instalment of Yggdrasil's 'of the Underworld' series, Hades will expect you on his arena alongside four brand new monsters, where two of our coveted GEMs, GigaBlox and Wild Fight, will be put into action. As you spin the underground arena machine and obtain high paid symbols, some will transform into Wilds, increasing your victories. The GigaBlox mechanic will make the payout even more spectacular, and the featured free spins mode will be further intensified by every Wild symbol, even those awarded by Wild Fight. Gamble your free spins with 2 levels of volatility and defy the depths with the buy bonus, leading you directly to free spins!
On a large 6×4 grid with a unique 4,096 paylines structure, Champion of the Underworld combines two of Yggdrasil's flagship GEM mechanics: GigaBlox creates giant symbol blocks while Wild Fight adds an additional Wild-generation layer. High-paying symbols transform into Wilds upon landing, and Free Spins are intensified by every Wild that appears, regardless of source. A gamble option with 2 risk levels offers a strategic choice before entering Free Spins.
✔️ Fans of the 'of the Underworld' series and dual flagship GEM mechanic combinations
✔️ Players who want a large-scale 4,096 payline structure on a 6×4 grid
✔️ Players who appreciate a gamble option with a choice of volatility level before Free Spins
❌ Not suited for beginners: the dual GigaBlox + Wild Fight mechanic requires understanding both systems
Grid: 6×4 · Lines: 4,096 · Base bet: €2 (min: €0.20 / max: €100) · Coins: 0.01–5 · RTP: 96% (fixed) · Hit Frequency: 25.76% · Max Multiplier: ×10,000 · Feature Buy-in: ✅ available
| ⚔️ GigaBlox™ + Wild Fight™ — Dual GEM A unique combination of two Yggdrasil flagship mechanics within a single slot: GigaBlox creates giant symbol blocks that make payouts spectacular, while Wild Fight generates additional Wild symbols through a separate mechanism. This rare pairing amplifies potential at every layer of gameplay. | 🔢 4,096 Lines — Unique Structure For the first time in the session, a specific payline count is explicitly stated — 4,096, rather than a range or Ways system. On a 6×4 grid this creates a colossal combinatorial reach, significantly exceeding the standard 20-40 paylines found in most session titles. |
| 👑 High Symbol Transformation to Wild High-paying symbols transform into Wilds upon landing, increasing the frequency of winning combinations. Free Spins are intensified by every Wild that appears — including those gifted by the separate Wild Fight mechanic, creating a cumulative reinforcing effect. | 🎲 Gamble — 2 Volatility Levels A unique strategic option: before entering Free Spins, players can choose between two risk levels through a gamble feature. This gives the player control over the balance between risk and potential reward, atypical for most slots in the session. |
In the base game, Champion of the Underworld operates at maximum combinatorial power: 4,096 lines across a 6×4 grid ensure frequent mechanical engagement, while the dual GigaBlox + Wild Fight system creates a constant flow of large symbol events. A 25.76% Hit Frequency at this scale of grid means regular, event-dense winning moments.
Free Spins with the volatility-level gamble choice are Hades' final battle on the arena: every Wild from both mechanics intensifies the round, GigaBlox unfolds at full strength, and ×10,000 alongside €1,000,000 await the champion brave enough to return from the underground depths. Feature Buy-in opens a direct path into the arena instantly.
