Fat Lady Sings is a 5-reel, 25-payline slot game focused around the titular “Fat Lady” that’s used in opera productions and shows.

You can access the game on many different casinos, like Mecca Bingo!

In general, it’s very similar to other games of the same type – you set bets with the “Coins” option and the “Lines” setting (or just use “Bet Max” to automatically fill out every payline) and begin spinning to see what you get!

There’s also an Autoplay option to skip the betting process entirely, letting you keep a chain of identical bets going.

Interactive Features

Like many online slot games, Fat Lady Sings has its share of bonuses you can activate. Slots players favourite part of a video slot is generally the bonus feature options.

There’s the Wild symbol, which is based after the game’s own logo. It substitutes for any other normal symbol in the game and can give you a winning combination by completing a payline so that it counts.

More of them are added if you activate Free Spins: you’ll even sometimes get stacked Wilds on the second and fourth reels, giving you a huge boost to your chances of winning.

The Masks symbol is the Scatter symbol. When you get three of them in a spin, regardless of their place on the reel, it activates the Free Spins bonus.

There are three major prizes, all of which you’ll win some variation on:

  • A random bonus multiplier.
  • A random amount of free betting money.
  • A random number of free spins .

These amounts are decided with a minigame. When you pick High, Medium or Low tones three times, and the Fat Lady will sing, breaking one of the containers that’s shown each time.

There’s also the unique “Gamble” feature that activates every time you hit a winning combination.

Clicking this button will give you a chance to massively increase your newly earned winnings at the cost of wiping them out entirely, too.

All you have to do is choose a card: if you get the colour right, you win twice as much, or four times as much if the suit is correct too. Get them both wrong, and you go back to the main game with none of those winnings.

Paylines and Stakes

As mentioned before, Fat Lady Sings has 25 paylines, although you aren’t forced to bet on all of them.

You can choose the exact number you want to bet on, this will reduce the cost of your overall bet while lowering your chances to get a winning combination. Pick the coins per spin that you’d like to wager, the more you stake, the higher the win.

The minimum bet size in terms of coins is 0.01, with the maximum being 0.25.

The game’s RTP is a decent 96.54%, with a default jackpot of around 3000 coins (although it can quickly rise as high as 100,000 coins).

Fat Lady Sings Slots Graphic Design

The design of Fat Lady Sings is very opera-inspired, taking place on an ornate wooden frame with very flashy, stage-style designs.

The symbols themselves – especially the character pictures – take a lot of inspiration from opera stereotypes. This makes the theme very clear even after a quick glance.

The pitch minigame that you play to earn free spins is also nicely designed. The game never deviated from its art style unless it absolutely must.

What Symbol Triggers the Fat Lady Sings Slot Bonus Free Spins?

As mentioned, the mask symbol is the scatter symbol. If you get three or more, you will unlock the bonus free spins. You will be awarded a random number of free spins, a random multiplier and random payout.

You could get upto 30 free spins and. a 5x multiplier on this feature.

Fat Lady Sings Slot on Mobile Phone

You can play Fat Lady Sings on multiple mobile casino sites and apps – any site that offers it and has its own app should have it available for you.

All the bonuses and gameplay features are generally the same, so there won’t be big differences between each of the versions.
