Champion of the Underworld GigaBlox Wild Fight Slot Review
The dead have packed the stands of a ruined colosseum, translucent spirits stacked in teal gloom between weathered columns, braziers burning orange over drifts of bone. Champion of the Underworld GigaBlox Wild Fight is that rare arena slot where the resident god earns his keep in the base game rather than waiting for the bonus to justify him. A follow-up to Hades Gigablox, it puts Yggdrasil’s god of the underworld to work on the natural reels, and the busier arena is the better for it.
The specs are chunky: 96% RTP, super high volatility, a 6×4 grid with 4,096 ways to win, and a hit rate of roughly one spin in four. Lucky Neko GigaBlox and 777 Volt GigaBlox cover similar ground elsewhere in the studio’s catalogue. This one shares its arena with none of them, and the difference is Hades himself.
Base Game & Features
Wins come from landing three or more identical symbols on adjacent reels, starting from the left. If a reel carries more than one copy of the winning symbol, the copies multiply: two on the first reel, three on the second and two on the third would count as a 2x3x2, or 12x the standard win.
Free Spins symbols are the exception, paying scattered rather than on the ways. Stakes run from 0.20 to 100 per spin.
The paytable splits into four high symbols and four low symbols. The highs are the arena’s monsters, and they’re the ones Hades is interested in fighting. Their values, shown as multiples of the default 2.00 stake, are:
- Top high symbol: 2.00 for six, 1.00 for five, 0.50 for four, 0.25 for three
- Second high symbol: 1.50 for six, 0.75 for five, 0.40 for four, 0.25 for three
- Third and fourth high symbols: 1.00 for six, 0.50 for five, 0.30 for four, 0.20 for three
- All four low symbols: 0.50 for six, 0.25 for five, 0.15 for four, 0.10 for three
Gigablox
On every spin, two or more reels connect to create at least one giga reel. Any symbol can arrive this way, sized 2×2, 3×3 or as large as 4×4, and the Free Spins symbol is no exception. Once the reels stop, each Gigablox splits back into its individual symbols, so a 4×4 block is effectively sixteen symbols working the 4,096 ways at once.
The splitting is what makes the mechanic more than decoration. A 3×3 Gigablox of the top symbol landing across the first three reels is nine matching symbols before the multiplication rules even get involved, and the same block of Free Spins symbols can carry a bonus trigger on its own.
Wild Fight
At random on any base game spin, Hades can step down and fight the monster symbols. It’s a simple duel: if he wins, the defeated symbol turns into a wild for that turn. Gigablox symbols can be converted too, so a single victory can flip a 3×3 block of monsters into a 3×3 block of wilds.
The wild itself only ever appears through Wild Fight, and it substitutes for any high or low symbol during the pay cycle. There’s no wild on the natural reels, which keeps Hades’ interventions as the only route to them.
Champion of the Underworld GigaBlox Wild Fight Free Spins & Bonuses
Free Spins
Landing five or more Free Spins symbols anywhere on the reels starts the round, and you get exactly as many spins as symbols landed. The count works by symbol size, so a 2×2 Gigablox of Free Spins symbols counts as four.
Every Free Spins symbol that lands during the round adds one more spin, and the session runs on the same 4,096 ways and the same bet as the triggering spin. The machine and its background change for the duration, so there’s no mistaking which mode you’re in. The reels keep the same six-by-four layout, but everything around them shifts to mark the occasion.
Multipliers
Inside the round, Wild Fight triggers on every single spin rather than at random. Each successful fight adds a point to the multiplier progress counter, and Gigablox conversions count by size: a 2×2 Gigablox wild is worth four points. The ladder, with two extra spins awarded at every level, looks like this:
- 9 successful Wild Fights: 2x multiplier, +2 spins
- 11 successful Wild Fights: 3x multiplier, +2 spins
- 13 successful Wild Fights: 5x multiplier, +2 spins
- 15 successful Wild Fights: 10x multiplier, +2 spins
- 17 successful Wild Fights: 25x multiplier, +2 spins
The multiplier applies to each spin individually and is held for the whole session. 25x is the ceiling; once it’s reached, the counter stops. Each level tracks its own progress, so the climb is cumulative rather than reset, and every wild Hades creates along the way feeds it.
Gamble
On entering Free Spins, there’s a chance to gamble the session for more spins. It’s a sword-drawing game: pick one sword out of ten, where the golden sword wins and the broken one loses.
There are two gamble levels to switch between, each with its own risk and reward, and you can move between them for each game. Lose the gamble and the entire Free Spins session is gone, so the choice is a real one.
Buy Bonus
A buy button sits alongside the reels and leads straight into Free Spins, skipping the scatter hunt entirely. There are two entry points:
- 5 free spins at the lower price
- 20 free spins at the higher price
Our Honest Verdict
Overall Rating: 7.7/10
Playing this is mostly waiting in Hades’ arena for the fights that matter. Gigablox land every spin and most do nothing, the god himself only climbs into the ring occasionally, and the base game rarely pays enough to write home about. The one reason to be here is the bonus, where the fighting never stops and every victory counts towards something that sticks.
The free spins ladder is the best thing in the game, and it’s not close. Because progress never resets and each level hands back two more spins, a good round feeds itself: climb past 10x and the session stops wanting to end. Most rounds won’t get that far, though. Seventeen successful fights for the full 25x is a tall order, and the top symbol paying just 2x for six of a kind means the base game won’t rescue a session that never reaches the arena’s main event.
This is one for players who enjoy a long build and can sit through a cold streak, and for anyone already fond of Gigablox. It isn’t built for steady small wins, and that’s not a flaw so much as the whole design. The underworld rewards patience here, and there’s real treasure at the bottom for those willing to dig for it.
