Thor Infinity Reels Game Review
Thor Infinity Reels earns its 6,055x ceiling the hard way. Every winning connection bolts a fresh reel onto the right edge of the grid and pushes the multiplier one step higher, so the payout only grows while the wins keep landing. There are no free spins to fall back on. Developed by ReelPlay and distributed through Relax Gaming, this 2021 video slot runs at 96.20% RTP by default and rises to roughly 96.6% if you buy the bonus. It is a high-volatility Norse slot built around one idea, and how much you enjoy it depends on whether that idea clicks for you.
In short: Thor Infinity Reels is a ReelPlay video slot from 2021, distributed by Relax Gaming and still in wide rotation as of 2026. Default RTP is 96.20%, rising to about 96.6% with the 100x bonus buy. Volatility is high, the max win is 6,055x, and the headline mechanic is Infinity Reels: a new reel is added on every winning connection and the multiplier climbs with it. There is no traditional free-spins round. It suits players who enjoy an escalating-streak build and can sit through dead spins waiting for a chain to grow.
A quick note on who made it, because sources disagree. Thor Infinity Reels is a ReelPlay title, developed by the studio behind the Infinity Reels engine, and it reached players through Relax Gaming's distribution network (the Silver Bullet / powered-by program). Depending on which lobby you open it in, you may see either name in the credits. Both are accurate. We flag it here so the provider label does not confuse you into thinking there are two different games.
This review covers what the mechanic does on the reels, where the 96.20% figure sits against comparable slots, how the max win is structured, whether the demo is worth loading, and what the 100x bonus buy really costs. The timeline is short and worth stating plainly: launched exclusively on February 8, 2021, widely released across Relax Gaming lobbies through spring 2021, and still demo-playable and stocked in casino lobbies as of 2026. If you came looking for a traditional free-spins bonus, the honest answer up front is that this game does not have one, and that shapes everything else about how it plays.
96.20% RTP and High Volatility, Explained in Numbers
Start with the return figure. The default RTP is 96.20%, which sits just below the loose 96% benchmark most players use as a pass line, and a fraction under the ~96.5% you will find on many Pragmatic Play and NetEnt headliners. Buying the bonus lifts the return to around 96.6%, which is a rare case of the buy option improving your theoretical edge rather than shortening it. Both figures come from SlotCatalog and clashofslots listings, not from the developer's own marketing.
What High Volatility Costs a Bankroll
Volatility is high, and the Infinity Reels design makes that concrete rather than abstract. Because the payout only escalates when wins chain together, most spins end after one or two connections and pay little or nothing. The math holds the big money back for the rare runs where reels keep stacking. A $0.40-per-spin player can sit through a long, flat stretch and then catch a single sequence that returns a session's worth of bets. That is the trade. Dead spins are the price of the occasional escalation. Budget for it: a $20 bankroll at $0.40 a spin buys 50 spins if nothing lands, which is a realistic dry run before a meaningful chain appears.
How the Infinity Reels Mechanic Actually Plays
The base grid is 3x4 with no fixed paylines. Land a winning connection and a new reel appears to the right, the winning symbols lock, and everything respins. Each added reel raises a running win multiplier by one. Keep connecting and the grid keeps widening, in theory without limit. The chain only stops when a respin fails to add a win.
In practice, most chains are short. You will add one reel, maybe two, and the sequence dies. The appeal is the tension of the streak: every locked win is a chance the next respin extends the board and bumps the multiplier again. Add 12 or more extra reels and the game pays an 888x jackpot, which is the standout moment the whole design is built toward.
The 888x Jackpot, Four Fixed Levels, and the Scatter Rounds
Supporting features fill the gaps around the central mechanic. Six or more hammer scatters trigger Jackpot Streak Respins. A Hold & Respin round awards cash prizes up to 100x. There are four fixed jackpot levels at 10x, 50x, 250x, and 2,000x, plus a Thor Wild and a Mjolnir Scatter driving the round triggers. It is a busy feature set stacked on top of one idea. The 888x reward for adding 12-plus reels is the true headline, and the fixed jackpots and Hold & Respin cash prizes are what most winning sessions are actually built from.
The 6,055x Max Win and Where It Sits
Maximum win is capped at 6,055x your bet. For a high-volatility slot in 2026 that is a middleweight ceiling. It clears older grid slots comfortably but trails the five-figure and six-figure caps now common on volatile Pragmatic and Nolimit City releases. On a $0.40 spin, hitting the cap returns $2,422. On a $10 spin, it is $60,550.
How Realistic Is the 6,055x Cap
Be realistic about the odds. Reaching 6,055x requires an exceptionally long reel chain, and the volatility profile makes that a rare-of-rare event. Most winning sessions here are built from modest chains and the mid-tier jackpots, not from touching the ceiling. Treat the max win as the theoretical top of the range, not a target you are playing toward.
Demo and Free Play Before Real Money
Load the demo first. This matters more than usual here, because the Infinity Reels rhythm is unlike a standard spinning slot, and the long gaps between meaningful wins can catch new players off guard. A few minutes in free play shows you how often chains actually extend and how the escalating multiplier feels in real time, without spending anything.
Finding a Working Demo in 2026
Most casinos that carry the game offer a no-registration demo on play credits, and as of 2026 the title still sits in Relax Gaming lobbies, so a working demo is usually two clicks from any Relax-powered site. Use it to decide whether the high-volatility pacing suits you before you commit real money. If a flat five-minute stretch with nothing landing would frustrate you, the demo surfaces that fast, and it is better to learn it for free.
The 100x Bonus Buy and What It Costs
You can skip the wait and buy the feature directly, priced at 100x your stake. At $0.40 per spin that is a $40 purchase; at $2 it is $200. As noted, buying nudges the RTP up to around 96.6%, so the option is mathematically kinder than most buys. That does not make it cheap. A 100x price tag is steep, and with high volatility the variance on a purchased feature is wide. You can drop 100x and see the feature return far less.
Where the Bonus Buy Is Blocked
The buy is not available everywhere. It is disabled in the UK and some other jurisdictions where regulators restrict bonus-buy mechanics, so whether you even see the button depends on your location and licence. If you play from a market where it is blocked, that is a fixed limitation of the game there, not something a casino can toggle on for you.
Where Thor Infinity Reels Fits
Play Thor Infinity Reels if the escalating-reel streak is the kind of tension you enjoy and you can sit through dead spins waiting for a chain to build. Skip it if you want a classic free-spins bonus, a high max-win ceiling, or steadier pacing. The 96.20% base RTP is fine but not generous, the 6,055x cap is modest for the volatility, and the absence of a free-spins round is a genuine structural gap rather than an oversight. Rating it 7 out of 10: a sharp central idea, an honest set of trade-offs, and a mid-tier ceiling.
Because provider libraries vary, look for it under both ReelPlay and Relax Gaming when browsing a casino's lobby. For more from this distributor, browse our Relax Gaming slots catalogue. If you like this developer's grid-based approach to Norse mythology, the Thor 10K Ways slot is another ReelPlay Thor title with a different engine and a different feel, and it is worth a look before you settle on either.
