Eternal Nile (Hacksaw Gaming) – Review & Demo Play

Ace Roll - Slot Developer in Eternal Nile

Ace Roll is a new studio working under Hacksaw Gaming’s OpenRGS platform, and Eternal Nile is the first outing. The partnership gives access to broad distribution while the team pushes a mechanic-first approach anchored by EchoSpins. I rate the ambition on show here, because debut slots often play it safe, yet this one leans into multipliers and repetition rather than a plain rehash. Release lands on 05/09/2025, setting the stage for a feature-led launch with proper reach.

Slot Theme And Storyline in Eternal Nile

The theme sticks to ancient Egypt with a tidy execution: stylised card ranks and deities sit on a 5x4 set against a temple backdrop. Horus stands to the left holding a large gem, acting like a silent partner as spins roll by. Animations are smooth, sound design fits the setting, and the whole package reads clearly at a glance. It looks familiar, but the atmosphere avoids clutter, so spotting lines and repeated positions during features feels natural.

It’s the contrast that sells it for me: a calm base with clear symbols, then the screen starts echoing once Horus blinks. The art makes the repeats satisfying to track, especially when the same clusters lock and the multiplier counter starts to matter. I prefer this clean approach over excess visual flares, as it helps focus on where the money is coming from during EchoSpins and the two free spin rounds.

Eternal Nile Rules And Gameplay

The action runs on a 5x4 layout with 20 fixed paylines, paying left to right from reel one, with wins starting at three-of-a-kind. Stakes range from €0.20 to €100 per spin, covering low testing spins through to hardened sessions. Combinations rely on adjacent reels, so line management matters when eyeing medium and high symbol clusters. I found the rhythm straightforward: quick spins, crisp hit windows, and a base game that lets you set bankroll pace while waiting for Horus to flick the switch.

EchoSpins sits at the heart of the ruleset. Any spin with at least one winning payline can pair with the Eye of Horus to trigger 1 to 8 respins, mirroring the same winning positions. During those repeats, multipliers that land are banked and applied to every respin. Values can be additive (2x, 3x, 4x, 5x, 10x) or multiplicative (x2, x3). That’s where the base game’s modest hits can snowball quickly when the counter builds.

Symbols And Paytable in Eternal Nile

Premiums are headed by Hathor at 2x, 4x, and 10x for 3, 4, and 5 of a kind, with Anubis and Sobek paying 0.7x, 2x, and 6x. Bastet and Osiris sit at 0.5x, 1.5x, and 4x. High cards A, K, Q return 0.2x, 1x, and 2x, while J and 10 pay 0.1x, 0.5x, and 1x. Five wilds can reach 10x, putting it alongside Hathor at the top end for capped line hits.

The set leans on clean, readable art, so picking lines is easy when clusters land across adjacent reels. Horus’s Eye is the trigger piece rather than a payer, sitting outside the hierarchy yet shaping outcomes whenever it appears with a made line. In practice, I prized medium symbols during EchoSpins, as repeated positions let Anubis and Sobek chains hold value while the multiplier jar fills. Low ranks do their job, chipping in to keep the meter moving.

Eternal Nile Bonuses And Special Features

EchoSpins can trigger whenever the Eye of Horus lands with a win, awarding 1 to 8 respins that mirror the original winning layout. Each repeat can drop additive multipliers of 2x, 3x, 4x, 5x, or 10x, and multiplicative multipliers of x2 or x3, all of which are collected and applied to every respin in that sequence. This creates a tidy ramp where modest starters can climb fast once the board repeats and the counter stacks across the set.

Echo Passage arrives with 3 scatters and grants 10 free spins. The base rules stay intact, but the Eye of Horus shows up more often, giving the respins far more looks across a bonus. I’ve had rounds where two or three EchoSpins bursts landed, and that was enough to turn an average start into a serious push. The cadence rewards patience, as you’re playing for repetition, board lock, and compounding multipliers rather than a single explosive screen.

Temporal Duat requires 4 scatters for 10 free spins and handles multipliers differently. Every multiplier that lands is stored in a single total above the reels; when EchoSpins trigger, that full value applies to each respin in the sequence, then resets. If you want shortcuts, Bonus Buy options exist: 3x bet for BonusHunt FeatureSpins with higher bonus odds (RTP 96.36%), 129x for Echo Passage (RTP 96.20%), or 200x for Temporal Duat (RTP 96.25%), with volatility rising on the priciest pick.

Eternal Nile RTP, Volatility, And Max Win

Eternal Nile runs variable RTP settings between 94.24% and 96.18%, so I aim for the highest configuration when possible. Volatility sits high, though the 29.38% hit frequency means small and medium wins drop at a fair clip. The ceiling is set at 10,000x your bet, which pairs neatly with the EchoSpins structure when multipliers stack in step. Taken together, it’s a maths model that wants repetition and patience, then pays off when the counters line up.

Final Thoughts on Eternal Nile

What a debut this is from Ace Roll. It may look like a standard Egyptian set at first glance, but EchoSpins adds a proper layer of excitement on every swing, with additive and multiplicative multipliers keeping sessions lively. I had fun with both free spin modes, and the maths felt fair for the volatility bracket. If this is their first step, I’m keen to see where they take the feature next.
