Design and Symbols

Thunderkick’s art department has done another great job on the design, beautifully capturing the ambiance and revelry of the Carnival. Set during the evening festivities on a bustling New Orleans Street, a packed crowd of revelers nods appreciatively to music blasting from the illuminated, brightly colored buildings either side of the thoroughfare. The purple game board sits center stage with a cast of colorful characters spinning to the upbeat tunes which accompany play.

Low-value symbols are the standard 9-A Royals. Medium paying symbols are represented by 4 colorfully costumed Carnival-goers (wearing blue, green, yellow, and red). The highest value regular symbol is a glittering crown that pays 20x stake for 6 across a pay line.  The scatter symbol is the Carnival Queen herself.

Special Features

Carnival Queen benefits from Avalanche reels, increasing win multipliers, and a highly lucrative free spins bonus round.

Avalanche Feature

Rather than spinning, Carnival Queen’s reels cascade into place rather like rocks tumbling in an Avalanche (hence the feature name). After a win lands the symbols making up the win disappear and new symbols ‘Avalanche’ down to take their place. If a new win is created the cycle will repeat and will continue until no new win appears, at which point a new spin will begin.

Avalanche Win Multiplier

For each Avalanche win, the multiplier increased by 1x. This continues as long as the winning streak continues. At the end of an Avalanche feature winning streak, the multiplier will reset to 1x.

Carnival Queen Free Spins

Free Spins are triggered by landing 3 or more scatter symbols for a minimum of 12 spins. Any scatters above 3 will add an additional 4 free spins. During the bonus round landing 2 scatters will award a further 3 free spins, with any additional scatters awarding 3 additional free spins.

During the bonus round the Avalanche feature win multiplier will not reset at the end of a winning streak. This will result in much bigger wins, especially towards the end of the round where the multiplier will often reach a decent double figure.


Another benefit of the free spin round is that if a wild symbol is present on the reels after a losing spin then it will eliminate every symbol on the same reel and row. New symbols will then fall into their place offering a further opportunity to land a winning combo and start the Avalanche feature.

Carnival Queen Summary

Carnival Queen is a great slot for Thunderkick to start their year off with. It has great visuals, a funky and fun theme, some popular features, and with a 22,700x stake win possible it clearly has awesome potential.

However, given that this is only rated medium volatility (Thunderkick rate it 47/100 for volatility), the chances of getting anywhere near the maximum win are extremely scarce, to say the least!

Personally I would have preferred higher volatility to give Carnival Queen a little more edge, but as mid-range slots go, this is a good one.

Cascading (sorry Avalanche) reels with increasing reel multipliers always seem to go down well, and Thunderkick has served up their own take on this familiar mechanic with aplomb. There’s nothing ground-breaking here, but nevertheless, this is a great addition to Thunderkick’s portfolio.
