Hounds of Hell Slot by Hacksaw Gaming

Hellhounds That Climb

Hounds of Hell drops Hellhound multiplier symbols onto a 5x5 scatter-pay grid. Land one anywhere and it spreads upward, filling its entire reel column with multiplier values. Each Hellhound carries either an adding multiplier (1x through 50x) or a multiplying one (x2 through x10). The values collect above each reel, and at the end of the spin, all collected multipliers add together and get paid out times your bet.

One Hellhound on reel 3 carrying 5x means 5x your bet from that reel alone. But this game is built for multiple Hellhounds landing simultaneously.

Roaring Packs Change the Math

When two or more Hellhounds land on the same row in adjacent reel columns, they form a Roaring Pack. Pack members get upgraded multiplier ranges. Standard adding multipliers cap at 50x, but Roaring Pack members reach 100x. Standard multiplying values go up to x10; Pack members hit x20.

Once a Hellhound joins a Pack, it stays in the Pack even after cascades separate the symbols. And when a Pack Hellhound spreads upward, the new copies also count as Pack members with enhanced values. So a single Roaring Pack formation at the bottom of two adjacent reels sends boosted multipliers all the way up both columns.

Hounds Are Loose

When the grid settles with no new wins forming, there's a random chance to trigger Hounds Are Loose. This feature removes every low-paying symbol from the grid, dropping in fresh symbols to replace them. It fires multiple times per spin sometimes, and each trigger brings an increased chance of Hellhound symbols appearing among the new drops.

In free spins, it's guaranteed after three consecutive non-winning spins. That safety net keeps dead streaks from completely wasting bonus rounds.

Two Bonus Modes

Three scatter symbols trigger "What The Hell!" with 10 free spins. Four scatters trigger "Who Let The Hounds Out?!?" with 10 free spins. The difference between them matters more than the names suggest.

What The Hell! runs progressive multipliers. Every Hellhound value collected during the entire feature stays above the reels, accumulating spin after spin. At the end of all 10 spins, the total gets paid out at once. This mode rewards patience - you're building toward one big final payout.

Who Let The Hounds Out?!? works differently. Multipliers reset between spins but you get Hell Reels - once a Hellhound lands on any reel, that reel guarantees a Hellhound every subsequent spin. By spin 5 or 6, you could have four or five reels all dropping guaranteed Hellhounds each round. The payouts come spin by spin instead of at the end.

Both modes retrigger with additional scatters: 2 for +2 spins, 3 for +4 spins.

The Bonus Gamble

When you trigger either bonus, you can gamble before it starts. Five Hellfire Orbs appear and you pick up to three. Each contains 2 to 10 extra free spins, or a Bonus Upgrade that immediately converts "What The Hell!" into "Who Let The Hounds Out?!?" with a full 10 spins.

The gamble adds a genuine decision point. Picking one orb is relatively safe. Three orbs is greedy. And the Bonus Upgrade changes the entire bonus structure mid-trigger. You can gamble once per bonus entry and once more after an upgrade.

Buy Bonus Pricing

Four tiers reflect the different entry points:

• Bonushunt FeatureSpins at 3x bet (5x higher bonus trigger chance)
• Howling FeatureSpins at 60x bet (guarantees 3+ Hellhounds per spin, no scatters)
• What The Hell! at 100x bet (direct entry)
• Who Let The Hounds Out?!? at 250x bet (direct entry)

The 250x buy for the upgraded bonus is expensive but skips the gamble risk entirely. At €0.10 base bet, that's €25 per feature entry. The 60x Howling option is interesting for players who want Hellhound action without committing to a full bonus - guaranteed multiplier symbols every spin at €6 per spin on minimum bet.

Base Game and 39% Hit Rate

The 39% hit frequency is unusually high for a Hacksaw slot with a 20,000x ceiling. Nearly four in ten spins return something. The base game doesn't feel nearly as punishing as Hacksaw's typical output. Low-pay symbols all share identical payouts (0.1x for 6 symbols), and five high-pay tiers range from 0.3x to 2x for minimum clusters. Small wins land often enough to sustain sessions.

The 20,000x cap itself is among the highest Hacksaw has offered without a jackpot system. Getting there requires multiple Roaring Pack Hellhounds with x10 or x20 multiplying values spreading across full reel columns during a bonus mode. Rare, but the path is mechanically clear.
