The design in Rio Riches Stacked Up is certainly colourful but it’s not quite up to the standard we’ve come to expect from the best of the Scandi developers. Flanked by a pair of carnival dancers, you’ll see A to 9 royal values alongside masks, parrots and drums. The best standard symbol is the green necklace that awards double your stake if you land 5 on a payline. Appearing on the middle reel only, the golden beach is the wild. Whenever it forms part of a winning combination, the payout gets a 2x multiplier boost and is doubled.

The main extra in Rio Riches Stacked Up is the Stacked Up feature. It’s triggered by landing 3 or more scatters on the same spin and awards 10 free spins as well as a payout of 3, 10 or 50 times your stake. On any free spin, reels can transform into wilds.

Land 3 or more scatters on the same spin during the Stacked Up feature and you’ll receive 5 more free spins on a machine with 30 extra paylines. Another 3 scatters brings another 30 paylines into play and adds another 2 free spins to your tally.

Land stacked Golden Beach symbols on reels 1 and 2 and you’ll trigger the Bonus Spin feature. This will give you a chance to land 1 of 5 potential jackpot prizes. Fill all 5 reels with Golden Beach symbols and you’ll pocket the Grand Bonus which awards a £15,000 jackpot.

Rio Riches Stacked Up is a pretty typical Ainsworth slot. The visuals are a little underwhelming and the soundtrack offers nothing to the Mardi Gras atmosphere. We found the features pretty lacklustre too. What saves Rio Riches Stacked Up is the Bonus Spin feature that can deliver some mighty jackpot prizes.

This slot didn’t really leave us in the party mood. Rio Riches Stacked Up is a game for Ainsworth fans only. If you like the theme, Play ‘N Go’s Samba Carnival should be tried.
