Rio Riches Stacked Up Slot Machine

Ever wondered just how many jackpots you could fit into a single slot? Well, Ainsworth are testing the limit in one of their latest releases, the Rio Riches Stacked Up video slot. Part of the popular new Stacked Up slot series, the Rio Riches Stacked Up gambling game is offering players the chance to land not one or two jackpots, but five staggering bonuses all in one game.

Whether you’re searching for top graphics or impressive bonuses, you’ll hit the jackpot (in more ways than one!) in this brand-new release from well-established slot developers Ainsworth. From your mobile device or on your desktop with no download needed, this slot is set to wow with mega bonuses, progressive jackpots, and a festive dose of free spins.

Join the Party in Rio

If you’ve ever been to a festival in Rio, then you’ll know that pretty much anything goes, especially when it comes to the famously flamboyant Rio Carnival. Ainsworth have not been shy in taking a leaf out of Rio’s book when it comes to flamboyancy in their new Rio Riches Stacked Up slot, but then Ainsworth are well-known for their interesting takes on top themes.

In the free Rio Riches Stacked Up slot, players are whisked away to the wonders of Rio, with exciting symbol designs, glorious sunsets, and a taste of that Rio wonder. The well-designed 5x3 reels layout boasts a 50 payline and a great set of symbols. These include the vibrant toucan, musical maracas, and beautiful jewellery.

This all combines to make an exciting slot, and a great addition to the well-stocked library of Ainsworth games. Standing alongside the Glitter Jewels slot in the Stacked Up collection, it also makes for yet another series of slots under the Ainsworth banner.

Stack up Your Wins

The whole concept of the Rio Riches Stacked Up is centred around the Stacked Up game feature, which provides the key excitement in the slot. Like other slot machines from Ainsworth to feature a bonus style that runs through multiple games, the whole design of the Stacked Up feature is pretty exciting and very in-depth.

The Stacked Up feature is triggered when three of the scatter symbols land on the reels. This starts up the main feature where players get an initial 10 free spins to play with. Who doesn’t love a good dose of the classic free spins bonus? Those free spins then have the chance to evolve, with the addition of random wilds, extra triggerable free spins, and the ability to turn the 50 payline slot into a 150-payline slot!

While these bonuses aspects are exciting, they don’t account for the five mega jackpots waiting. These consist of three set bonuses (mini, minor, and maxi) and two progressive jackpots (major and grand). The bonuses are triggered via the sunset symbols, of which there are two variations: the normal sunset and the golden sunset. Different combinations of these trigger different jackpots, with the grand jackpot triggered when four reels of normal sunsets appear with the addition of the middle reel being filled with golden sunsets.

A Festival of Fun

The Rio Riches Stacked Up slot delivers on bonus features, with some impressively different ways to win on the reels, but it also delivers on ease of play. The slot is laid out like most classic slots with a 5x3 reels set, and the control panel located at the bottom. In the standard game, there are 50 paylines, with the transformation via the bonus adding another 100 to the game. If you’ve experienced any of the latest releases from Ainsworth, then the likelihood is, you’ll be quite familiar with the overall gameplay.

When it comes to placing a bet, the choice is down to you whether you want to go all in and play for real cash, or just check out the excellent design and gameplay with a spin for free. If you’re not sure which is right for you, then it can help to check out the RTP of the slot and have a look at the volatility. For Rio Riches Stacked Up, the slot offers a 90% RTP and a medium volatility; this may be a little too risky for some players.

From One Festival to Another

If the festivities of Rio Riches Stacked Up have got you in the spirit to party, then don’t worry, there are plenty more festival slots out there to check out. Carnival in Rio, by Gamesys, is different take on the famous Rio Carnival, with a matching 50 payline and medium variance to Rio Riches Stacked Up. There are free spins on the table, stacked wilds, and a whole extra row to play with, making this slot one worth checking out.

For those players keen to pay a visit to a different festival, then the Festival of Lights slot from Blueprint may just be a winning slot to check out. If you don’t mind taking a slight hit to the payline count and going down to 40, then this vibrant slot is an excellent choice.

Unleashing the Spirit of Rio

Rio Riches Stacked Up is a wonderful new slot from Ainsworth, offering up a great mix of new game features and excellent modern designing. The symbols are unlikely to win the competition for the best among the most recent online slots, but they do work well, delivering a modern feeling slot that complements the advanced bonuses very effectively.

While the design of the slot is good, the bonuses are where the party is really at in Rio Riches Stacked Up. The Stacked Up feature would easily survive as a standalone bonus, but with the addition of the mega list of jackpots, Ainsworth are really out to impress with Rio Riches Stacked Up. Despite the return to player percentage being quite low compared to other similar Ainsworth slots, Rio Riches Stacked Up has a lot going for it. Want to check out the thrills of Rio? Look no further than this top new gambling game.
