Book of Mrs Claus Features

Like most 'Book Of' slots, this one contains a free spins feature that triggers once you land 3 or more scatters. You can trigger 10, 12 or 25 free spins by landing 3, 4 or 5 scatters respectively. At the start of free spins, there's a special symbol assigned that becomes an expanding reel throughout free spins. Each book acts as a wild and a scatter.

At the end of each base spin, you choose to respin a reel as many times as you like - but this comes at a cost. Only wins that involve the respun reels are paid. This is called the HyperSpins feature and can be found in other titles such as 9 Masks of Fire HyperSpins and Playboy Fortunes HyperSpins.

Book of Mrs Claus Review

It's the most wonderful time of the year and Santa Claus has gone missing. Fear not though, as Christmas is going to be saved by Mrs Claus and her infamous book.

Book of Mrs Claus plays on 5-reels with 10 paylines and is developed by Aurum Studios presented by Microgaming. This Christmas slot features HyperSpins and free spins leading to wins of up to 5,000x your stake.


This slot is exactly what you'd expect with a Christmas slot as the graphics are quite generic and unpolished at times. The background looks like an old Christmas card that you'd get from an elderly relative. That's not to say that it looks bad, but it doesn't look great either.

On the reels, you'll find Mrs Claus with reindeer and other strange animals that make no sense. She's joined by an owl and a fox because everyone knows they are Christmas animals. It's even more confusing that there are more suitable animals surrounding the reels, but they don't have a symbol.

As for the music, you can delight your ears with charming Christmas music - or at least mute it if it gets too much. After a few spins, you'll definitely be reaching for the mute button.


The gameplay is pretty standard for a 'Book Of' slot with a free spins mechanic paired with an expanding symbol. You'd think the additional of HyperSpins would change the gameplay drastically, but it sadly doesn't do much. You can respin a reel for a price, but that's about it.

All of the relevant buttons are at the bottom of the screen with the spin button centred. Further to the left, you'll find an additional button that leads to other settings you may need such as sound.

Win Potential

It all begins with a solid RTP of 96.50% which is over the industry standard and features high volatility gameplay leading to larger wins at a less frequent rate.

In this slot, you can win up to 5,000x your stake and nothing more. You can win this through the free spins round, but nothing more. Whilst, 5,000x your stake is a decent amount, it's low for a modern online slot.

Our Verdict

Sadly, Book of Mrs Claus fails to deliver something unique and exciting. The design is confusing and feels dated at times, whilst the gameplay is too standard.

Many developers have created 'Book Of' slots with simple mechanics but made up for it with an impressive design. If you love straightforward games and Christmas, then give this slot a spin.

For those of you wanting something more thrilling for Christmas, try Santa Stacks or Santa's Big Bash Megaways instead.
