Odin Infinity Reels Slot Review
Odin Infinity Reels is a high volatility Norse mythology slot by ReelPlay (via Yggdrasil) with 96.18% RTP. It was the first slot to combine Infinity Reels and Megaways — reels expand infinitely to the right on every win, adding a progressive multiplier, with an 888x bonus jackpot for reaching 12+ added reels.
What is Odin Infinity Reels?
Odin Infinity Reels featuring Megaways, developed by ReelPlay (Sydney, Australia) and distributed through Yggdrasil Gaming's YG Masters program, was released in May 2021. It merged two of the most innovative slot mechanics into a single game for the first time. The base grid starts with 3 reels, each displaying 2-5 symbols (Megaways variable), creating the initial set of ways to win. Norse mythology symbols populate the reels: Odin himself (highest value), his wolf Fenrir, horse Sleipnir, ravens, and rune-inscribed stones as low pays. The Valknut wild substitutes for all regular symbols. Every winning combination triggers the Infinity Reels mechanic: a new reel appears to the right, and a win multiplier increases by 1x. If the new reel produces another win, another reel adds and the multiplier increases again — with no upper limit on expansion. If a sequence reaches 12 or more added reels, an 888x bonus jackpot is awarded on top of all accumulated wins. The Gungnir scatter triggers free spins (8, 10, or 12 spins determined by a bonus wheel), with a second wheel selecting the multiplier increment (1x, 2x, 3x, or 4x per added reel). The critical free spins difference: the multiplier never resets between spins. It persists and grows across the entire bonus round, creating exponential ceiling potential. The 20,000x hard cap (maximum $240,000 per spin) constrains the theoretical infinite expansion.
RTP, Volatility & Max Win
Odin Infinity Reels' 96.18% RTP sits slightly above the industry average. Operator-adjustable variants exist though specific reduced values aren't publicly documented. The 20,000x maximum win places it in the top tier alongside Barn Festival, Emerald King, and Great Rhino Megaways. The 28% hit frequency is noteworthy for a high-volatility slot — roughly 1 in 4 spins triggers the Infinity Reels expansion. The 888x bonus jackpot (at 12+ added reels) occurs approximately once every 63,323 spins — rare but not impossibly so. The mathematical tension is between the theoretical infinite expansion and the practical 20,000x cap: the Infinity Reels mechanic has no theoretical upper limit, but the cap constrains maximum payouts. During free spins with a 4x multiplier increment, reaching a multiplier of 20x+ is achievable through sustained winning sequences across multiple spins. The non-resetting free spins multiplier is the primary ceiling driver — without it, each spin would start fresh and 20,000x would be unreachable. The $12 max bet significantly limits absolute ceiling values: 20,000x at $12 = $240,000, compared to $2,500,000 at a $125 max bet slot with the same cap.
How Odin Infinity Reels Works
The starting grid has 3 reels with 2-5 symbols per reel (Megaways variable). Wins form with matching symbols on adjacent reels left to right. Odin is the highest-paying symbol, followed by Fenrir (wolf), Sleipnir (horse), and ravens. Six rune stones serve as low pays. The Valknut wild substitutes for all regular symbols. Every winning combination triggers Infinity Reels: a new reel appears to the right, and a 1x win multiplier is added. If the new reel creates another win, the process repeats — the reel count and multiplier both grow by 1 with each consecutive win. The sequence ends when an added reel fails to produce a win. In the base game, the multiplier resets after each complete sequence.
Bonus Round & Free Spins
A winning combination involving the Gungnir scatter triggers free spins (approximately once every 315 spins). Two bonus wheels spin: the first awards 8, 10, or 12 free spins; the second selects the multiplier increment per added reel (1x, 2x, 3x, or 4x). The critical upgrade: the win multiplier DOES NOT RESET between free spins. It accumulates across the entire bonus round. A free spin that adds 3 reels at 4x increment grows the multiplier by 12x — and that multiplier carries to the next spin. By the end of a productive bonus round, multipliers can reach double or triple digits. Retrigger: a scatter win during free spins awards 4 additional spins with no limit. The 888x bonus jackpot is available in both base game and free spins when 12+ reels are added in a single sequence.
Special Features
The Infinity Reels + Megaways combination creates a unique mathematical interaction: as reels expand, both the number of ways to win AND the multiplier increase simultaneously. Standard Megaways slots have a fixed number of reels (6) with variable rows — Odin starts with 3 reels and adds unlimited reels with variable rows, meaning the ways-to-win count grows exponentially with each addition. The 888x bonus jackpot is a cultural reference (8 is lucky in Norse and Chinese traditions) and provides a concrete aspirational target during expansion sequences. The non-resetting free spins multiplier transforms what could be a gimmicky expansion mechanic into a genuine ceiling system: persistent multiplier growth across 8-12+ spins creates the mathematical runway needed to approach 20,000x.

Common Misconceptions
What Players Say About Odin Infinity Reels
Odin Infinity Reels generates enthusiastic discussion from players who experience the reel expansion mechanic. The visual spectacle of watching the grid grow rightward with each consecutive win — from 3 reels to 5, 7, 10+ — creates excitement that fixed-grid slots cannot replicate. The 888x bonus jackpot at 12+ reels serves as a visible target during expansion sequences, with community members tracking reel counts in real time during streams. The non-resetting free spins multiplier is the feature that generates the most excitement in community discussions, with forum posts detailing multiplier accumulations across entire bonus rounds. The primary criticism is the $12 max bet: players who appreciate the mechanic wish they could stake higher, and the absolute ceiling of $240,000 is modest compared to $125 max bet slots with the same 20,000x cap. ReelPlay's low brand recognition means many players discover the slot through streams or recommendations rather than browsing. Community consensus: a genuinely innovative slot limited by its bet range.
Session Notes
Odin Infinity Reels sessions demonstrated the Infinity mechanic's practical range. The 28% hit frequency meant roughly one in four spins triggered reel expansion. Most expansion sequences added 1-2 reels before stopping — producing modest returns of 2x-8x with small multiplier increments. Sequences reaching 4-5 added reels were less common (approximately once every 30-40 wins) and produced 15x-35x returns. Our longest base game expansion reached 7 added reels (total 10 reels) with a 7x multiplier, returning 52x before the sequence ended. The 888x jackpot at 12+ reels was not triggered during testing. Free spins triggered once via scatter win (12 spins, 2x increment). The non-resetting multiplier accumulated across the round: productive spins added 2-4 reels each, growing the multiplier to 18x by spin 9. The final three spins at 18x+ multiplier produced our strongest returns. Total free spins payout was 347x — our session peak. The visual experience of watching the grid expand rightward was genuinely engaging, especially during longer sequences.
Expert Assessment
Odin Infinity Reels is the most mechanically ambitious slot in Yggdrasil's distributed catalogue — the first and still the best combination of Infinity Reels and Megaways. The unlimited reel expansion with progressive multipliers creates a visual and mathematical experience no fixed-grid slot can match. The non-resetting free spins multiplier provides genuine 20,000x ceiling potential. The 888x bonus jackpot at 12+ reels adds a concrete aspirational target. The $12 max bet is the critical limitation — this mechanic deserves a higher bet range. For players who value mechanical innovation over bet flexibility, Odin delivers a unique experience.
Is Odin Infinity Reels Worth Playing?
Odin Infinity Reels represents what happens when slot designers prioritise mechanical innovation over commercial convention. The Infinity Reels + Megaways combination — unlimited reel expansion with variable rows, progressive multiplier, and an 888x bonus jackpot at 12+ reels — creates a slot experience that no fixed-grid game can replicate. The non-resetting free spins multiplier transforms the bonus from a set of independent spins into a cumulative journey where each productive expansion raises the floor for everything that follows. The 20,000x cap provides genuine ceiling potential. The honest limitations: the $12 max bet constrains absolute payouts to $240,000 (compared to millions at higher-stake equivalents), the 96.18% RTP is only marginally above average, and ReelPlay's brand obscurity means many players will never discover it. For players who value mechanical novelty — watching a slot physically grow, tracking multiplier accumulation, reaching for the 888x jackpot threshold — Odin Infinity Reels is among the most innovative designs in the current slot landscape. For players who need high bet limits or brand recognition, the limitations are structural.

Frequently Asked Questions
What is the RTP of Odin Infinity Reels?
Odin Infinity Reels has a default RTP of 96.18%. Operator-adjustable variants likely exist per industry standard. The default is marginally above the industry average.
How do the Infinity Reels work?
Starting with 3 Megaways reels (2-5 rows each), every winning combination adds a new reel to the right and increases a win multiplier by 1. If the new reel produces another win, another reel adds. There's no upper limit on expansion. In the base game, the multiplier resets after each sequence; in free spins, it never resets.
What is the 888x bonus jackpot?
If a single expansion sequence reaches 12 or more added reels, an 888x bonus jackpot is awarded on top of all other wins. It's a fixed bonus (not multiplied by the round multiplier). Probability: approximately 1 in 63,323 spins.
What is the maximum win?
The maximum win is 20,000x your total bet (hard cap of $240,000 per spin). At the $12 max bet, this equals $240,000. The theoretical infinite expansion is constrained by this cap.
How do the free spins multiplier increments work?
Before free spins, a bonus wheel selects the multiplier increment: 1x, 2x, 3x, or 4x per added reel. At 4x, each reel addition grows the multiplier by 4 instead of 1. The multiplier never resets between free spins — it accumulates across the entire bonus round.
Who made Odin Infinity Reels?
Developed by ReelPlay (Sydney, Australia) and distributed through Yggdrasil Gaming's YG Masters program, released May 2021. ReelPlay invented the Infinity Reels mechanic. Odin was the first slot ever to combine Infinity Reels with the Megaways engine.
