Immortal 5 Slot Review – Demo, RTP & Features

Immortal 5 is a superhero-themed online slot developed by Relax Gaming in collaboration with CasinoDaddy.

Moving away from the duo’s previous sloth-inspired releases, this high-volatility title introduces five genetically enhanced superheroes battling for massive wins across a futuristic city backdrop.

Packed with expanding Hero Wilds, Respins, selectable bonus modes, and huge multiplier potential, Immortal 5 delivers an action-packed experience aimed at players who enjoy feature-heavy slots.

Played on a 5-reel, 15 pay-line layout, the game offers an RTP of 96.10%, a betting range between €0.10 and €100, and a maximum payout of 10,000x your stake.

While the comic book heroes may be original creations, the gameplay will feel familiar to fans of Relax Gaming’s multiplier-driven mechanics.

Game Features

15 Fixed Pay-lines

Immortal 5 is played across 15 fixed pay-lines, with wins awarded for matching symbols from left to right.

The slot features:

• Betting range from €0.10 to €100
• High volatility
• RTP of 96.10%
• Maximum win of 10,000x

The five superhero premium symbols pay up to 20x your stake, while both Wild types substitute for all regular symbols and award 20x for five of a kind.

Expanding Hero Wilds

One of the game’s standout mechanics is the Expanding Hero Wild.

Hero Wilds can land on any reel and:

• Expand to cover the entire reel.
• Receive multipliers between x2 and x100.
• Combine with other Hero Wilds by adding their multipliers together.

Landing multiple Hero Wild reels can dramatically increase payouts during both the base game and bonus rounds.

Immortal Respins

Whenever one or more Immortal Wilds appear during a normal spin, the Respin Feature begins.

During Respins:

• Triggering Wilds remain locked.
• Newly landed Wilds also lock in place.
• Every new Wild awards another respin.
• Wins are evaluated after each respin.

The feature ends only when no additional Wilds land.

Immortal Silver Bonus

Landing 3 Silver Bonus Scatters triggers the Silver Bonus.

Players can choose between two different bonus modes:

Hero Mode 1

• 6 Free Spins.
• Progressive global multiplier.
• The multiplier increases whenever multiplier symbols or Hero Wilds appear.

Hero Mode 2

• 6 Free Spins.
• Every symbol position develops its own multiplier.
• Multipliers double whenever involved in a win.
• Hero Wilds collect and permanently store reel multipliers.

Before the feature begins, players receive two mystery Power-Up picks, which may award:

• +3 Free Spins.
• Multiplier Boost.
• Additional Hero Wilds.

Immortal Gold Bonus

Landing 3 Gold Bonus Scatters activates the premium bonus round.

The Gold Bonus includes:

• 6 Free Spins.
• Choice between Hero Mode 1 or Hero Mode 2.
• Two standard Power-Up picks.
• One exclusive Super Power-Up.

Super Power-Ups include:

• Immortal Transfer (extra Wild transformations).
• Starting Hero Wild Reel.
• +6 Extra Free Spins.

This bonus offers the game’s highest winning potential.

Hero Bet & Bonus Buy

Players can increase feature frequency using Hero Bets.

Available options include:

• 1.5x Bet – Higher chance of triggering either bonus.
• 5x Bet – Increased chance of triggering the Gold Bonus only.

Where available, Bonus Buy includes:

• Random Bonus Feature — 100x bet.
• Hero Spin — 500x bet.

The Hero Spin is an all-or-nothing gamble that either awards nothing or instantly pays the full 10,000x maximum win.

Final Thoughts

Immortal 5 video slot successfully blends superhero action with Relax Gaming’s trademark multiplier-heavy mechanics. Between Expanding Hero Wilds, sticky Respins, selectable bonus modes and numerous Power-Up combinations, there is always something happening once the features begin rolling.

While the original comic book characters may not have the instant appeal of famous superhero franchises, the gameplay itself delivers enough excitement to keep high-volatility fans entertained.

Players who enjoy feature-rich slots with strategic bonus choices and explosive multiplier potential should find plenty to like in Immortal 5. It may not reinvent the genre, but it offers a polished and rewarding experience that comfortably earns its place among Relax Gaming’s stronger modern releases.
