Carnival Queen 2 Slot Review: Thunderkick's 25,000x Party

Carnival Queen 2 slot review: the short version

This Carnival Queen 2 slot review covers one of the most interesting Thunderkick slots of 2025. The studio released it on 27 August 2025, six years after the original street-party slot.

We rate it 9/10 and give it our Masterpiece label. The reason is simple. The game does what a high-volatility slot should do.

The 94.18% RTP is on the low side, and we cover that below. For players who want swings and a big ceiling, the design still earns its score.

Reels, rows and ways to win

The grid has six reels, and each reel shows between two and seven symbols on every spin. That gives a minimum of 5,040 ways to win and a maximum of 117,649.

Wins pay left to right on adjacent reels, with three or more matching symbols needed. The ways count changes constantly, so no two spins feel quite the same.

The symbol set is simple. Low pays are the card royals from 9 to A. Above them sit masked carnival characters in several colours, and a gold crown tops the table. Six crowns in a way pay 10x the bet.

Cascades and the Infinite Multiplier

Every win removes the winning symbols, and new ones drop in to fill the gaps. The chain continues until no new win forms.

This is the heart of the game. A short chain pays modestly, while a long chain on a tall grid can climb quickly. The base game is a hunt for that one spin where the cascades keep coming.

The Infinite Multiplier is also what gives the bonus round its weight, as the next section explains.

Exploding Wilds

The wild is a firework. It substitutes for every symbol except the bonus scatter, and it always explodes. When it lands as part of a win, the blast happens after the win is paid.

That blast does two jobs. It opens space so the reel heights can grow, which raises the ways count. It also forces new symbols to drop, which can start another cascade and push the multiplier up.

Compared with the row-and-reel destroying wilds of the first game, these feel more controlled and easier to read.

Free spins bonus

Three or more scatters anywhere on the grid start the free spins. You get 12 spins, plus 4 more for each scatter beyond the third. Four scatters give 16 spins and five give 20.

The key rule is that the multiplier is not reset. Whatever value the triggering spin reached carries into the bonus, and it keeps climbing with every cascade. It does not drop back between spins.

The round can also be extended. Two scatters during the bonus add 3 spins, and each extra scatter adds 2 more. A long bonus with a growing multiplier is where the 25,000x ceiling becomes plausible.

This is the only bonus round in the game, so there is no secondary feature to learn. Some players may want more variety. We see it as focus, because everything in the base game feeds this one round.

Bet+ options and Feature Buy

Thunderkick adds a Bet+ menu where regulations allow it. Bonus Boost costs 1.5x your bet and makes the bonus about twice as likely. Bonus Boost Plus costs 3x and makes it about five times as likely.

There are also two direct purchases. You can buy the free spins for 100x your bet. For 175x you can buy them with at least 10,000 ways active from the start.

These options are not available everywhere. UK players, for example, cannot use them. Check what your casino offers before you plan around them.

Carnival Queen 2 RTP and max win

The Carnival Queen 2 RTP is 94.18%, and the game is rated high volatility. That RTP sits below the usual range for modern slots, and it is lower than the original.

The Carnival Queen 2 max win is 25,000x your stake. On a 1.00 bet that equals 25,000. That is a theoretical ceiling reached very rarely. Treat it as the top of the range, not as a target.

Bets run from 0.10 to 100 per spin, so you can scale the risk to your bankroll. Our scoring favours high volatility and a large max win, and this game rates strongly on both.

Carnival Queen 2 demo and free play

The easiest way to judge this game is the Carnival Queen 2 demo on this page.

Use the demo to check three things. First, see how often cascades build a multiplier past x5. Second, watch how the grid height affects your chains.

If the pace suits you, you can then look for the game at a crypto casino that carries Thunderkick slots.

Who should play it

This slot suits players who like long dry stretches broken by big chains. It rewards patience and a bankroll that can absorb losing runs.

It is less suited to players who want frequent small wins or a high RTP. If you prefer low variance, look elsewhere among Thunderkick slots.

The theme works well. The street-parade setting, with fireworks overhead and spectators in the windows, feels more involved than in the first game.
