ReelPlay is one of those Australian studios that did not try to flood the market with fifty near-identical ideas and hope something stuck. The company launched in 2014 as Chance Interactive, rebranded in 2019, and built its reputation on slots that usually hinge on one strong mechanical hook rather than empty noise. Infinity Reels became that hook. The idea is simple on paper and far more lively in motion: the game starts on a compact grid, then adds a fresh reel every time a winning chain reaches the far right and continues to improve. With each extra reel, the pressure rises, the route to a bigger payout opens wider, and in many titles the multiplier climbs as well. That is why the series never feels static. It behaves like a machine that keeps leaning forward, as if every spin is trying to talk itself into becoming something larger than it first looked.
What makes the Infinity Reels line genuinely interesting is that ReelPlay did not trap the mechanic inside one theme or one tempo. Instead, the studio pushed it through lost empires, Norse myth, street-crime swagger and fantasy warfare, while keeping the core logic intact. The series at Glitchspin casino normally begins on three reels and four rows, then stretches outward whenever the rightmost side stays involved in a win. Some releases add a rising win multiplier for each new reel, others bolt on respins, free spins, bonus wheels, jackpot-style prizes or the studio’s famous Infinity Bonus. According to PlayUSA and Casinos.com, the wider framework often awards 888x the base stake once the expanding grid reaches a key threshold, which gives the series a clean identity across very different games.
El Dorado Infinity Reels and the art of making greed look organised
El Dorado Infinity Reels is the slot that explains the whole series in one hit. Its official release date on Yggdrasil’s game page is 4 March 2021, its RTP sits between 96.51 and 96.54 per cent, volatility is rated medium to high, and the top advertised win reaches €250,000. The storyline heads straight into the age of the Aztec Empire, where the promise of impossible wealth is not treated as a background detail but as the engine of the game itself. Everything here revolves around the idea of pushing deeper into a city of gold that never quite runs out of reasons to keep going.
The real strength of El Dorado is how its bonuses fit the theme without becoming clunky. The base mechanic is Infinity Reels, so the grid can keep extending as long as the win survives on the right edge. On top of that, the game offers Free Spins and a Jackpot Prize, but its cleverest wrinkle is the decision layer inside the bonus feature. Yggdrasil describes three options called Store, Gamble and Play, which means the feature is not just a dead automatic payout. It asks for a choice and turns a simple trigger into a small tension point. That matters because El Dorado is not trying to be chaotic. It behaves more like a slot about measured escalation, where every extra reel, every choice and every surviving combination nudges the round closer to a richer outcome. In the Infinity Reels family, it remains one of the cleanest examples of the formula done right.
Thor Infinity Reels brings thunder, hammers and proper volatility
Thor Infinity Reels, released on 1 April 2021, pushed the formula into louder territory. The official figures place RTP at 96.20 per cent, volatility at high, and the maximum advertised payout at €242,238. The plot is rooted in Norse myth, but it avoids turning the theme into a museum exhibit. This is not a polite retelling of old legends. It is a slot built around battlefield force, divine favour and a sense that the screen can kick open at any second if the hammers and symbols align.
Its bonus structure is much more aggressive than El Dorado’s. Thor keeps the Infinity Reels core, yet adds Infinity Bonus and Jackpot Respins as headline features. Yggdrasil states that jackpot respins work across the expanding reel layout, with hammers spread over multiple symbols on potentially endless reels. The game also awards an Infinity Bonus worth 888x the bet once 12 additional reels or more have been reached. That threshold turns expansion into a proper event rather than just a visual flourish. Every time the layout grows, the round feels like it is marching toward a second game hidden inside the first one. Thor’s appeal comes from that combination of scale and danger. The game does not pretend to be subtle. It is built to lurch from standard wins into something much fiercer, which is exactly why it still stands as one of the most memorable Infinity Reels titles.
Age of Beasts Infinity Reels twists the formula into a fantasy brawl
Age of Beasts Infinity Reels arrived on 2 December 2021 and gave the series a rougher fantasy edge. Officially, the game carries 95.57 per cent RTP, high volatility, and a top win of €197,650. The setting is a struggle for dominance in a world of magical fighters and mythical creatures, so the story is less about treasure hunting or divine intervention and more about survival inside a violent pecking order. That difference matters because the whole machine feels designed around layered escalation, not one single jackpot moment.
Its bonus package is one of the smartest in the Infinity Reels line. Yggdrasil says every Free Spins trigger comes with a Bonus Wheel feature that can award instant cash prizes, extra free spins, and symbol win multipliers, with the possibility of landing one of four larger bonus prizes. PlayUSA adds that the free spins round starts with eight spins and a 1x base multiplier, while the bonus wheels can expand the setup before the feature properly begins. On top of that, 13 additional reels unlock the 888x Infinity Bonus. The result is a slot that does not rush to the finish. It stacks systems on systems. First the expanding reels, then the trigger, then the wheel, then the spin count or multiplier upgrades, and then the hunt for the Infinity threshold. In practical terms, that makes Age of Beasts one of the most layered entries in the whole branch. It has more moving parts than Thor, but it keeps them tied to one clear goal: turn each feature into fuel for the next one.
West Coast Cash Infinity Reels proves the mechanic can swagger
West Coast Cash Infinity Reels took the series somewhere completely different. The Light and Wonder page lists the release date as 15 February 2023, while Bigwinboard reports RTP of 96.16 per cent, high volatility, and a maximum win of 20,350x the base stake. The storyline swaps myth and fantasy for palm-lined streets, hustlers, dealers, enforcers and a criminal rise-to-riches tone that feels half street saga, half exaggerated urban legend. It is a bold move because Infinity Reels could easily have stayed trapped in epic themes, but this game shows the mechanic still works when the tone turns grimier and more playful at the same time.
The feature set here is dense and probably the most technical of the group. Alongside the usual Infinity expansion and a symbol multiplier that rises by 1 each time a new reel is added, West Coast Cash runs an Infinity Bonus that pays 888x total bet if a round adds 12 or more reels. The main event, though, is LevelUp Respins. According to Bigwinboard, landing at least three Cash symbols triggers the feature, locks those symbols in place and starts three respins on a grid that only shows Cash or Special symbols. Any new Cash symbol resets the respin counter to three. When a reel fills with four Cash or Special symbols, another reel is added. Cash values begin at 1x to 5x bet, then grow as dollar signs accumulate. After six dollar signs, a symbol levels up and can increase in value or transform into one of four special characters. Hustler rises automatically, Pimp can jump by 10x to 50x bet, Dealer spreads value to adjacent symbols, and Enforcer pulls nearby values into itself. A 100x bet Buy Bonus can trigger the feature directly. This is not a tidy little add-on. It is practically a second game stitched into the first, and that is exactly why West Coast Cash still lands as one of the strongest, most muscular Infinity Reels releases.
