El Dorado Infinity Reels (ReelPlay): Overview

Because it’s long been linked with fortune and untold riches, the name El Dorado regularly pops up in gambling. Depending on the source, it can point to the legend of the Golden Man or the so-called Golden City. European explorers famously chased this tale as they pushed through South America, looting and pillaging along the way. In the end, they never found the mythical place—likely because it never existed. Slot players, however, get another shot at the legend courtesy of Australian studio ReelPlay.

Founded in 2014, the developer previously known as Chance Interactive went through a rebrand earlier this year and released several titles in the process—Hypernova Megaways standing out most thanks to its use of the Megaways engine, which always draws attention. ReelPlay’s latest release, El Dorado Infinity Reels, instead leans on a proprietary mechanic, and it turns out to be a pretty solid one.

El Dorado shifts, scrolls, and grows, but it begins with a 3-reel, 4-row layout set in a South American jungle backdrop. Waterfalls cascade behind the reels while a mellow pan pipe theme plays throughout. Visually, it’s polished, the symbol set is entirely original, and the overall first look is very appealing. Players can choose stakes from 20 p/c up to $/€25 per spin, with wagers split by 20 to determine coin value. It runs smoothly across devices and maintains its look regardless of screen size.

Wins are created in a slightly unusual way. The rules say all symbols act as scatters, though it doesn’t function exactly like a typical scatter setup. Rather than paylines, symbols pay in coins when 5 or more appear from left to right. Those winning clusters can also trigger the Infinity Reels mechanic, which we’ll get to shortly.

The paytable—arguably more complicated than it needed to be—includes 10 standard symbols. Six coloured gems cover the low-paying end, while 4 masks represent the premium symbols. The golden mask is the top payer at 5 times the coin value. That’s modest on its own, but the expanding reels and climbing multipliers compensate for the low base values.

There’s also the Wild Native, which assists in forming wins by substituting for every symbol except the Temple. RTP varies from 95.51% – 96.54% depending on how players handle free spins. The configuration and math model combine to deliver reasonably regular base-game hits while reserving plenty of potential for the bonus features.

El Dorado Infinity Reels (ReelPlay): Features

There’s plenty going on here, so we’ll begin with the headline mechanic: Infinity Reels. The slot starts on 3 reels. When symbols on the far-right reel contribute to a winning combination, an extra reel is added to the grid. That new reel spins, and if it extends the winning combo, another reel is added. The chain continues without a set endpoint, stopping only when no additional helpful symbols land. This can produce some hefty returns, and once the Symbol Multiplier comes into play, the potential ramps up even more.

The Symbol Multiplier is a progressive value that begins at x1, and each newly added reel increases it by +1. As with the open-ended Infinity Reels, the multiplier itself has no maximum cap.

During free spins, the Symbol Multiplier can be enhanced further. The Temple symbol is the trigger, and landing 5 or more awards 10 Free Spins. Before the feature starts, players must pick one of three choices—bank, gamble, or play. If you bank the free spins, you don’t play them immediately. Instead, the next time free spins are triggered, the Symbol Multiplier increases by +2 rather than +1. Free spins can be banked up to three times, meaning the third level increases the Symbol Multiplier by +3, and the forth level by +4.

Players can also choose to gamble the free spins. Win the gamble and the Symbol Multiplier automatically advances to the next level before free spins begin. Lose, and the free spins are lost completely.

To sweeten the deal, Reel Play has also added a separate jackpot feature. The idea is simple in principle: add at least 12 new reels in a single spin to win a jackpot worth 888 times the stake. As reels and wins accumulate, a small display in the top-right shows how many more reels you still need to reach the jackpot target. Symbol Multipliers do not affect the jackpot.

El Dorado Infinity Reels (ReelPlay): Verdict

El Dorado Infinity Reels ended up being an unexpectedly enjoyable release. The moment you hear “El Dorado” paired with rising win multipliers, Gonzo’s Quest is the obvious comparison. While there are similarities on paper, the actual experience is very different. ReelPlay has delivered something genuinely distinctive that’s well worth a closer look. Its strength lies in straightforward play that hides a collection of smart—and sometimes very rewarding—features. When a big win hits and the reels slowly scroll back, Beethoven’s 9th Symphony kicks in to give the moment a celebratory feel.

Infinity Reels is a clever mechanic, and it can create some huge sequences when it starts chaining properly. Better still, it can be just as impactful in the base game as it is during free spins. The knowledge that adding 12 new reels can land a jackpot also helps keep the game feeling fresh. On top of that, the ability to bank free spins to build a massive Symbol Multiplier adds even more long-term appeal. For players who prefer higher risk, the free spins gamble option is there too.

All things considered, ReelPlay has delivered a strong package. El Dorado looks notably better than average and brings the kind of high volatility you’d expect alongside a maximum potential of 6,250 times the stake. If the Infinity Reels idea catches on—and there’s little reason it won’t, especially with the progressive multiplier—it’s likely we’ll see it again. For now, its first appearance results in a solid slot that offers far more depth than it initially suggests. Based on El Dorado, the rebrand appears to have paid off, and it’ll be interesting to see what the refreshed ReelPlay produces next.

If you enjoy El Dorado, consider trying Giza Infinity Reels, which is ReelPlay’s second slot to use the Infinity Reels mechanic. NetEnt also uses a comparable concept in Gods of Gold INFINIREELS, which may be worth a spin as well.
