Get ready to party Brazilian style in Festival Queens, a 5 reel, 40 payline carnival-themed slot powered by 2 By 2 Gaming. Goodies on offer in this fiesta include transforming symbols, a pick me bonus and a feature round that awards up to 20 free spins with a doubling 2x multiplier. Join the action from between 40p and £160 per spin.

The design in Festival Queens has a real carnival feel – joining the lower value spade and heart symbols are tambourines, drums, masks and fireworks. Better still are the quartet of carnival queens who award between 30 and 200 coins if you manage to land 3, 4 or 5 on 1 of the 40 paylines. The top paying symbol is the Festival Queens logo which awards 1,000 coins for a 5 symbol combo.

There are some nice animations to herald each winning spin, all backed by a bouncing soundtrack, samba style drums and call and response vocals. It all comes together rather nicely. Look out for the wild – it can hit on reels 2, 3, 4 or 5 and replaces all other symbols apart from the Carnival symbol.

Land 3, 4 or 5 of those Carnival scatters anywhere on the reels and you’ll trigger the Festival Free Spin Bonus feature and with it 10, 15 or 20 free spins. Before the free spins start, pick 1 of 4 boxes to reveal a Festival Queen. Whenever she forms part of a winning combination during the free spins, that payout will be boosted by a 2x multiplier and doubled.

There are a couple of other features worth noting too – on each spin, stacks of mysterious white masks can land. They can transform into all other symbols apart from the wild and scatter and help build some big winning combinations. The Mystery Masks are in play during the free spins round too.

You’ll see that red boxes can sometimes appear at random above the reels. Once you’ve collected 5 of them, you’ll trigger the Pick a Mask Bonus feature – just choose from 1 of the 5 boxes shown to reveal cash, a multiplier or win all prizes.

As you’d hope from a party-themed slot, there’s plenty to enjoy in Festival Queens. The design is good and the soundtrack bops along nicely. The features aren’t bad either. The Mystery Masks can help things along but the best opportunities come in the free spins round. We found it a hit and miss affair, missing totally sometimes but on other occasions winning over 80 times our stake on a single free spin. We’d put the variance in the medium range.

We were pleasantly surprised by Festival Queens. Combining a party vibe with some good bonus rounds, this Brazilian-themed slot is an all-round entertainer. If you like the theme, I recommend Play ‘N Go’s Samba Carnival.
