Thor Infinity Reels Slot Review
Weapons stand half-swallowed by fog on a frozen Norse battlefield, waiting for a fight that never quite arrives, and that’s an honest picture of how Thor Infinity Reels plays. This is a slot that runs on patience rather than fury: most spins settle quietly, and the whole game is built on the rare round that decides not to stop.
ReelPlay built this one around their Infinity Reels mechanic, the same engine that powered West Coast Cash Infinity Reels, reviewed here in 2022. The numbers make an unusual shape: 96.2% RTP, low volatility and a max win of 6,055x the bet, with stakes from 0.20 to 40 per spin. Low variance paired with a ceiling that size is a rare combination, and the growing reel set is the reason it works.
Base Game & Features
Every spin begins on three reels and four rows. Symbols pay from left to right, and they all pay as scatters, so a win needs the same symbol on consecutive reels starting from the leftmost. The Hammer is the exception: it counts wherever it lands and needs at least five participating symbols to factor in.
Pays are calculated by multiplying the number of participating symbols by that symbol’s value from the paytable. Wins are multiplied by the base bet, which is the total bet divided by 20. Coinciding wins for different symbols are added together.
The headline numbers for the regular game:
- RTP: 96.2% (96.6% when buying the bonus)
- Volatility: low
- Hit frequency: 13.64%, roughly one spin in seven
- Max win: 6,055x the bet
- Stakes: 0.20 to 40 per spin
The Infinity Reels Mechanic
If the rightmost reel improves any symbol combination on a spin, an extra reel is added to the right and spun. If that new reel improves things again, another arrives. The chain only stops when a reel fails to add anything, and there’s no limit on how many can stack up.
That’s the entire engine: a win that keeps growing buys the grid more space to grow in. Wins are only calculated once no extra reel is added, so a single round can run through a dozen or more spins of its own before it settles. Nothing is paid until the chain breaks.
Each new reel also bumps the Symbol Multiplier by one. It starts at 1 in every game round, climbs with every reel added, and again has no cap. The multiplier applies to all symbol wins except the Hammer, which plays by its own rules entirely.
The two systems feed each other. A long expansion chain doesn’t just widen the grid, it multiplies whatever that chain eventually pays, so a five-reel run collects its prize at 5x rather than 1x. The Symbol Multiplier resets to 1 at the start of each new game round.
Thor himself is the wild, standing in for every symbol except the Hammer. The Hammer is the scatter: it doesn’t pay like the other symbols, it counts wherever it lands, and it’s the key to the respins round covered below.
Thor Infinity Reels Bonus Respins & Infinity Bonus
Bonus Respins
Six or more Hammer symbols anywhere in view trigger the Bonus Respins. You get three respins, all Hammers lock in place, and every remaining position spins again. Land a new Hammer and it locks too, resetting the respin count back to three.
The round then plays out step by step. Each respin either adds a Hammer, which locks and resets the count, or it doesn’t, which burns one of the three. Fill a reel with four Hammers and another reel is added to the right and spun, so the round can keep expanding sideways for as long as the Hammers keep coming. When the respins run out, every Hammer on the grid awards the prize printed on it.
The round has its own set of rules that cut against the rest of the game. Thor is absent throughout. Regular symbol pays don’t apply, and the Symbol Multiplier doesn’t touch Hammer prizes. The bonus ladder looks like this:
- Grand Bonus: 2,000x total bet
- Major Bonus: 250x total bet
- Minor Bonus: 50x total bet
- Mini Bonus: 10x total bet
- Standard Hammer prizes: 1x to 100x total bet
None of the bonuses are progressive, and all of them can be awarded more than once in a single round, so a reel-filling run of Hammers can stack several ladder prizes together. Respins play at the bet of the triggering spin.
The Infinity Bonus
Reach 12 or more added reels in a single game round, in normal play or during the respins, and the Infinity Bonus pays 888x the total bet. The Symbol Multiplier isn’t applied to it, so the prize is a flat 888x. Twelve reels is a long way from three, and that’s the point: it’s the reward for the rare round that simply refuses to stop.
Buy Bonus
Where the jurisdiction allows it, the Bonus Respins can be bought for 100x the bet. The purchased spin is guaranteed to trigger the round, arriving with between six and 15 reels and between seven and 24 scatters already in play. The Infinity Bonus can fire from the triggering spin too, which is the only route to buying your way near the 12-reel threshold.
The buy tiers at a glance:
- Cost: 100x bet per spin
- RTP when buying: 96.6%
- Triggering spin: six to 15 reels, seven to 24 scatters
Our Honest Verdict
Overall Rating: 7.6/10
Playing this is a lot like standing in that fog waiting for the thunder: long stretches of quiet, then a round where the reels keep coming and everything changes. The reason to pick it over plainer Norse slots is that tension, and low volatility means you get to feel it without funding it with a huge bankroll.
Its best trick is the way one mechanic feeds itself, since every added reel both widens the grid and raises the multiplier on whatever it eventually pays. Its worst is the feature everyone buys in for: the respins ladder stops at 2,000x with the multiplier excluded, so the game’s signature round pays less than its quietest one can.
It’s for players who like a build, who enjoy watching a small win talk itself into something bigger. Anyone chasing a single headline jackpot will find the ladder too modest. But for the patient, Thor’s slow storm is well worth standing in.
