Hounds of Hell (Hacksaw Gaming) – Review & Demo Play

Hounds of Hell - Overview

I dropped straight into the underworld with Hounds of Hell, a 5x5 scatter pays slot where six or more matching symbols anywhere trigger wins and cascades follow. The core loop revolves around Hellhound multipliers that spread up their reel and get collected, turning ordinary drops into punchy payouts. The base game runs hot in crimson, while bonuses shift the palette to icy blue, setting the mood for those bigger moments. No wilds here, just clean pay-anywhere play and the hounds doing the heavy lifting.

The math sits in that medium-high pocket, so I expect steady clusters with bursts when the hounds align. What sells it for me is how those multipliers compound through cascades, especially when Roaring Packs kick in. It feels familiar if you play Hacksaw often, yet the reel-top collection and the pack upgrades add a fresh edge. Two free spins modes and a pre-bonus gamble round out a setup that rewards timing, patience, and a bit of cheek.

Slot Details for Hounds of Hell

RTP is 96.27% on the top setting, with alternative versions at lower rates, so I always check the paytable. Volatility is medium-high, and the hit frequency sits around 39.8%, which lines up with the flow I felt in testing. Bets run from 10p up to £100 a spin. It’s a 5x5 grid with Scatter Pays, no fixed lines, and cascades after every win. Max win caps out at 20,000x, available across base and bonuses if the multipliers stack in your favour.

Theme, Audio + Symbols in Hounds of Hell

The atmosphere is grim and focused: hellhounds frame the grid, drums thud away, and the shift to a colder look in bonuses adds bite. It’s built mobile-first and runs neatly in portrait, so quick sessions feel natural. The visual language is sharp rather than flashy, with each cascade and multiplier reveal carrying weight. I like how the soundtrack sits under the action instead of shouting over it, letting the hounds and their spreads become the star.

On symbols, 10 to Ace are the lows. Premiums are eldritch icons, with the top symbol reaching 50x for 10+ in view. Six-of-a-kind scatter wins range roughly from 0.1x to 2x, scaling to 5x to 50x for 10 or more. Special symbols matter most: Hellhounds deliver adding or multiplying bet multipliers; FS Scatters trigger the bonuses; Hellfire Orbs appear in the gamble. There are no wilds, so progress comes from clusters, cascades, and how well those hounds climb.

Bonus Features in Hounds of Hell

Hellhounds are the engine. After cascades finish, a landed Hellhound spreads to the top of its reel, revealing either adding values from 1x to 50x or multiplying values from x2 to x10. Totals above reels are collected bottom-to-top, left-to-right, then summed and applied to the stake. If two or more hounds land adjacent on the same row, they form a Roaring Pack, upgrading their ranges to 5x–100x and x3–x20. Packs persist even if cascades separate the symbols.

Hounds are Loose can fire when the grid settles with no new wins. It clears all royals so fresh drops enter, with a higher chance of Hellhounds; it can repeat within the same spin. The Bonus Gamble appears on entering a feature. I pick up to three Hellfire Orbs, each holding 2–10 free spins or a Bonus Upgrade if I started on What the Hell!. It’s not a wipeout gamble; you still play a feature, which keeps the sweat fair.

What the Hell! grants 10 free spins from three scatters. Hellhound multipliers persist above the reels for the entire round, and Hounds are Loose is guaranteed after three non-winning spins. Land two or three scatters for +2 or +4 spins. Who Let The Hounds Out?!? starts with 10 spins from four scatters or via the upgrade. First-time hounds activate Hell Reels that guarantee a Hellhound each spin on those reels; reel totals pay every spin and reset. Feature buys sit at 3x, 60x, 100x, and 250x (non‑UK).

Hounds of Hell Expert Verdict

Hounds of Hell hits that sweet spot where Scatter Pays and reel-top multipliers mesh with proper pace. The base game has rhythm thanks to the symbol clears, while the Roaring Pack spikes are where sessions turn. I rate the split free spins: persistence for compounding versus Hell Reels for repeated pressure. With 20,000x on the table and a 96.27% RTP top model, it’s a solid pick when I want volatility tied to mechanics that actually earn their keep.
