Relax Gaming builds a supernatural high-variance engine across 5 reels and 15 paylines — a traditional layout that concentrates its 10,000x ceiling into infrequent but explosive bonus sequences.

Immortal 5 is Relax Gaming working against the grain — a 5-reel, 15-payline slot in an era dominated by expanding grids and ways-to-win engines. The traditional layout is a deliberate choice, not a limitation. With a 19.67% hit frequency and high variance math, the game runs cold by design, banking return mass into the bonus round where the 10,000x ceiling becomes relevant. The 96.10% top RTP is competitive, and the three-tier RTP structure is worth flagging to check at your casino. Not the most visually spectacular slot in the Relax Gaming catalogue, but mechanically honest and well-targeted at players who want disciplined variance over spectacle.
Immortal 5 is a December 2024 release from Relax Gaming built on a deliberately traditional 5-reel, 15-payline structure. In a market saturated with expanding grids and ways-to-win mechanics, the fixed 15-payline layout is a considered choice — it keeps the payout structure transparent and concentrates each spin’s value into clearly identifiable line combinations rather than diffusing it across hundreds of simultaneous ways. The supernatural theme frames five immortal characters as the high-value symbol set, each with defined individual payout rates that the 15-payline structure makes easy to track.
Immortal 5 — base game.
The three RTP tiers — 96.10%, 94%, and 86% — span a 10-percentage-point range that makes the active configuration at your casino a significant factor. The gap between 96.10% and 86% is not marginal on a high volatility slot where long dry spells already concentrate return mass into infrequent events. Verify the active version before playing. The $0.10 minimum bet is accessible for budget sessions, while the $100 maximum accommodates higher-stake play where the 10,000x ceiling translates to meaningful absolute returns.
The high-value symbol set is built around five distinct immortal characters — each with individual payout tables that differentiate their contribution to winning combinations. On a 15-payline structure, landing multiple matching high-value symbols across several active lines simultaneously produces clearly readable returns. The character design gives each symbol a visual identity that makes tracking which symbols are performing on a given session straightforward, an advantage the traditional payline format has over sprawling ways-to-win layouts.
Wild symbols substitute for all paying symbols across active paylines. On a 15-payline grid, a wild landing in a central reel position can complete combinations across multiple lines simultaneously — the fixed payline structure means the number of lines a wild completes per spin is predictable and directly calculable based on its reel position. This transparency is a practical advantage for players tracking session variance and understanding why specific spins produced their outcomes.
The free spins round is the primary vehicle for the 10,000x max win. Triggered by scatter combinations, the bonus carries enhanced mechanics — additional wild placement, multiplier activation, or expanded symbol behaviour — that elevate the per-spin payout potential substantially above base game levels. With a 19.67% base game hit frequency, the bonus trigger is the rare event the session is built around, and its outcome determines whether a session is profitable or not. Extended base game sequences between bonus triggers are by design rather than anomaly.
Immortal 5 is certified across three RTP configurations: 96.10%, 94%, and 86%. The active tier at any casino is operator-determined. The 10-percentage-point spread between the top and bottom tiers is particularly consequential on a high volatility slot — the 86% version returns meaningfully less over any session length than the 96.10% version, and the gap compounds across the variance range. Check the game information panel or help screen before beginning a session to confirm which version is active.
Most high-variance slot releases in 2024 default to expanding grids, cluster pays, or ways-to-win structures that generate hundreds or thousands of simultaneous win evaluations per spin. Immortal 5 runs against this entirely. The 15 fixed paylines produce a smaller number of evaluated combinations per spin, which means individual payline wins are larger and more meaningful relative to total bet — a $1 bet on 15 paylines means each line is valued at approximately $0.067, and a maximum-payout line win returns a much larger proportion of total stake than the same symbol combination in a 50,000-ways format where individual way values are fractional.
This structure benefits players who want to understand exactly why a spin returned what it did. The 15-payline layout allows line-by-line win attribution without needing to parse a mass of simultaneous sub-cent ways contributions. For the high volatility audience that actively tracks session variance and bonus performance, this transparency has real practical value — especially when evaluating whether a bonus round performed to expected value or ran cold.

Immortal 5 — free spins bonus.
Immortal 5 earns a 7.9/10 from SlotArk — rated Great. The 15-payline structure is a clean framework for a focused high variance slot, the 96.10% top RTP is fair, and the 10,000x ceiling has a realistic bonus-route mechanism. Best for players who value payline transparency over grid complexity and are comfortable with extended low-hit base game sequences.
Each spin evaluates 15 fixed paylines rather than hundreds or thousands of ways. Individual payline wins are larger relative to total stake than equivalent combinations in ways-to-win formats, and each winning line is clearly identifiable on the grid. The tradeoff is fewer simultaneous win opportunities per spin, meaning the base game produces wins less frequently than expanding-grid titles at similar volatility levels.
Three tiers: 96.10%, 94%, and 86%. The active version at your casino is operator-configured. The 10-percentage-point gap between top and bottom tiers is significant — check the game information panel before playing to confirm which version is in use.
The maximum win is 10,000x your total stake. It is reachable during the free spins bonus when the game’s enhanced mechanics produce maximum multiplier or wild combinations across multiple high-value paylines simultaneously.
