Hacksaw Gaming take you to the gates of a fiery underworld with their Hounds of Hell online slot. Demonic dogs guard a 5x5 grid of high card emblems and ritual symbols which pay in any places. In common with most games from this developer, Hounds of Hell is packed with fiendishly good bonus features.
Cascades trigger on every win, which can lead to further wins as new symbols appear. The Hellhounds spread across reels and carry multipliers, while several can land at once to boost those values. Hounds can trigger another cascade on random non-winning spins, and there are two levels of free games bonus rounds. Hellhound multipliers build throughout the free spins with the hounds loose at all times in the top-tier feature.
This is a highly volatile game with average returns of 96.27% at the best online slots sites. You can unleash the Hounds of Hell on desktop or mobile devices for wins of up to 20,000x the total bet.
Fantastic animations and a haunting soundtrack bring the guardians of the gateway to Hell to life. Hounds snarl and snap to the sides of the grid, moving to the top if you play on an Android, iOS, or Windows mobile. A blood-red, Gothic stairway leading to who knows what horrors is in view behind. Symbols on the grid continue the theme, with spikey metallic styled high card icons, pentagrams, ghostly skulls, and staring eyes among them.
Entry to Hell costs from 0.10 to 100.00 with up or down arrow buttons next to the bet indicator making it easy to pick a level to match your bankroll. Various bonus buy options improve the odds of features or unlock them right away.
Symbols pay when at least 6 of the same type land in any places on the 5x5 grid and the 3 lines on the control panel open a paytable which details how much each is worth at the current stake. Payouts range from 0.10 – 5x the bet with the lowest value symbol in 6 – 10+ positions, to 2x – 50x for the staring eye.
Autoplay and Turbo options are available from some territories, but like the bonus buy features, these are unavailable to UK players.

The popular Cascades mechanism features here, with winning symbols removed from the reels and those above dropping down to take their places. New symbols appear from above and if this forms another win, you get another cascade, and so on until there’s no further win.
Hellhounds can land on any spin, staying on the reels until any cascades have come to an end. They then spread upwards, if possible, to fill any rows above, revealing multipliers at the top which combine and then apply to the win. There are two types of multipliers. Adding versions increase the combined values by 1+ to 50+, while Multiplying versions boost the values by 2x to 10x.
If more than one adjacent column and row holds Hellhounds, they trigger the Roaring Packs of Hell feature with higher multipliers. Adding values are now from 5+ to 100+ and Multiplying values increase to 3x to 20x. Once part of the pack, a Hellhound remain so, even if it ends up separated from others over any cascades.
Randomly, a Hounds Are Loose feature triggers at the end of cascades. All playing card symbols are removed and new symbols drop in, which can lead to another win and start the sequence over again. There’s an increased chance that the new symbols will include Hellhounds, although wins from this are not actually guaranteed.
What The Hell! uk free spins begin if 3 FS bonus symbols land at once. You get 10 spins, with any 2 or 3 FS symbols adding 2 or 4 to the total respectively. Hellhound multiplier values build above each reel for the duration of the free games and add together at the end. If you have 3 consecutive non-winning spins, Hellhounds are guaranteed to appear on the grid.
Land 4 FS symbols on a base game to get the enhanced Who Let The Hounds Out!?! feature. These play out in the same way as the What The Hell! round, but once a Hellhound lands on a reel, at least one will appear on the same reel for the rest of the feature. Multipliers above the reels are paid on each free spin before resetting, ready for the next Hellhound to add their values.
Before either free spins feature starts, there’s the option to gamble for the upgraded feature or extra spins. Take the gamble and you are presented with 5 Hellfire Orbs. Pick 3 of these to reveal from 2 to 10 extra spins, or if you trigger the What The Hell! feature, an orb can also reveal the Who Let The Hounds Out!?! bonus games.
With fabulous graphics and multiple features, the Hounds of Hell slot machine is a thrilling journey into a demonic world. Perhaps a wild symbol would have improved things even further, but it’s a minor point.
What you have is a fast-paced game where cascades can lead to multiple wins in a row, and Hellhounds can build multipliers through a sequence. Free spins with extra Hellhounds and ever-increasing multipliers are where you have the best chance to grab the highest wins. Be careful with the gamble option though, as you could find an orb that takes you right back to the base games.
