Blood Eternal

Blood Eternal Slot Review

Blood Eternal is a gothic vampire slot from Betsoft, released in 2017 as part of the developer's acclaimed Slots3 series. Set against a haunted mansion backdrop with rich 3D animations, it pulls players into a world of immortal creatures and dark romance. The game runs on 6 reels with 30 paylines that pay in both directions, creating a distinctive experience among vampire-themed slots.

Game Overview

Blood Eternal is built on Betsoft's Slots3 engine, which means polished cinematic visuals and detailed character animations throughout every spin. The theme centres on a centuries-old vampire tale, with gothic architecture, candelabras, and richly drawn characters filling the reels. It launched in September 2017 and remains one of Betsoft's more atmospheric releases.

• Developer: Betsoft
• Theme: Vampire / Gothic horror
• Reels: 6
• Rows: 3
• Paylines: 30 (pays left to right and right to left)
• RTP: 95.03%
• Release: 2017

The RTP of 95.03% sits slightly below the current industry average of around 96%, so it is worth factoring that into how long you expect your sessions to run. The both-ways payline structure does add genuine value by effectively doubling the number of potential winning combinations on each spin.

Symbols and Paytable

The symbol set is built around the vampire mythology. The top-paying regular symbol is the Double Bat, which counts as two standard Bat symbols when it lands. A combination of six Double Bats across a payline pays at a substantial multiplier, and because the game pays both ways, that same combination can trigger a win from either direction.

Lower value symbols feature gothic decorative icons that match the mansion setting. All symbols benefit from the both-ways mechanic, so even mid-range combinations hit more frequently than a single-direction game at the same payline count.

Features

Wild Symbol

The Wild substitutes for all symbols on the reels except the Scatter symbols. When it lands in place of a Bat symbol during a combination, it counts as a single Bat rather than a Double Bat. This distinction matters when you are chasing the top bat combinations, but the Wild remains a strong addition to most other winning lines.

Vampire Free Spins

The most significant feature in Blood Eternal is triggered by landing a Vampire symbol and a Human symbol side by side on adjacent reels during the base game. The Human and Vampire characters appear in both male and female versions, and any pairing of the two triggers the bonus. Landing them awards 8 free spins.

During the free spins round, the Vampire and Human symbols that triggered the bonus lock in place as sticky Wilds for the full 8 spins. On top of that, 2 to 6 additional random Wilds drop onto the reels at the start of each free spin. This can produce some compelling combinations, particularly when Wilds land alongside Bat symbols on multiple paylines. The feature can also retrigger if a new Vampire and Human pair land adjacent during the bonus.

Double Up Feature

After any winning spin in the base game, players can choose to enter the Double Up round. This is a straightforward coin-flip gamble, asking you to pick Heads or Tails. A correct choice doubles the win; an incorrect choice forfeits it. The Double Up is optional and can be skipped entirely if you prefer to collect wins as they land.

Double Bat Symbol

The Double Bat is one of the more unusual mechanics in the game. When it appears on a reel, it contributes the value of two regular Bat symbols to any combination it forms part of. Combined with the both-ways payline structure, landing multiple Double Bats in a single spin creates the potential for the game's largest base-game payouts.

Gameplay and Volatility

Blood Eternal plays at a medium volatility level. The 30 both-ways paylines generate regular small and medium wins, while the free spins round with random Wild placement provides the main route to larger payouts. The Double Bat mechanic adds an extra layer of potential to base-game spins without requiring any bonus trigger.

Betting starts from £0.60 per spin at minimum coin size with all 30 lines active, and the maximum stake reaches £150 per spin. The game is not structured around a progressive jackpot, so the maximum possible win comes from the combination of base-game mechanics and free spins during a high-variance spin sequence.

The pace of play suits those who enjoy atmospheric, visually rich slots where the bonus round arrives at a reasonable frequency. Eight free spins is a modest award compared to some modern slots, but the added Wilds during the round compensate for the lower spin count.

Mobile Compatibility

Blood Eternal is fully optimised for mobile devices across iOS and Android. Betsoft built the Slots3 series with cross-device compatibility in mind, so the 6-reel layout and character animations scale well on smaller screens. The control layout adapts to touch input without cluttering the display, and the gothic visual style translates clearly at mobile resolutions.

Verdict

Blood Eternal delivers a well-constructed vampire slot with a strong visual identity and a feature set that rewards patient play. The both-ways payline mechanic and the Double Bat symbol create genuine variety in the base game, while the Vampire Free Spins round offers a clear target for bonus hunters. The 95.03% RTP is the one area where the game lags behind newer titles, so it suits players who prioritise theme and atmosphere alongside competitive returns.
