Symbols and Payouts of the Book of Mrs Claus

With so many Christmas slots in the Ontario market, each one has to work harder to grab your attention. We took a look at the payouts and features of this one to see what’s involved.

The Symbols

The low-paying symbols are card symbols decorated with Christmas items, while the high-paying symbols are Mrs Claus and her animal helpers. Her book is the scatter symbol.


There are 10 fixed paylines, and only the highest win on each line is paid. Books pay on any position, but other wins are paid from left to right.

Min/Max Bet, Autoplay Option

You can choose your coin size, ranging between $0.01 to $0.50 per coin, with one to five coins bet per line. So your minimum bet would be $0.10, while the maximum bet is $25. You can use the autospin feature to play between 10 and 100 spins.

Book of Mrs Claus RTP

The RTP of this slot is 96.31%, but 96.50% with respins. Ideally, players should always look for High RTP slots!


This slot has high volatility

Jackpot and/or Maximum Win

You can win up to 5,000x your bet in this slot.

A Festive, Basic, Base Game, Book of Mrs Claus didn’t impress us with its base game payouts or basic stats, as they’re similar to many other slots. However, the maximum win is decent and might help you feel like it’s Christmas if you get it.

Game Features

Although the base game doesn’t do anything new, the game features tell a different (Christmas) story.

Wilds, Respins, and Other Features

Your wild symbol is also your scatter symbol, namely the red book. It substitutes for all symbols and can pay up to 100x your bet if you land five or more.

Respin Feature

Book of Mrs. Claus Respin Feature Ontario
Additional 10 Free Spins

You can respin any single reel after spinning all the reels. Each reel will have a different cost to respin, but if you know your paylines, you can spin a reel to try to land that winning payline if the other four reels are in the correct place.

Extra Spins

You can win between 10 and 25 extra spins if you land three or more scatters. It’s also possible to land 10 more extra spins if you land another three scatters during your extra spin rounds.

Expanding Symbols

Before your extra spins are activated, a random symbol will be chosen to become an expanding symbol during the extra spins. If this symbol lands in a winning payline, then all the same symbols on the reels will expand to cover the entire reel.

Book of Mrs Claus Sound & Graphics

While the graphics are filled with cute animals and 2D art, they look slightly outdated.

Slightly Outdated, But Nice Graphics

While we feel the quality of the graphics can use a facelift, it provides cute 2D art, which follows the theme of Santa’s jolly wife. However, it doesn’t provide anything unique in the sound or graphics.

If Your Game is Interrupted, Here are the Solutions

While you play slots, there are times your game is interrupted. We look at what solutions you can use in the case of an interrupted game.

  1. If your game is interrupted, then you can reopen the game within the casino’s grace period to complete any unresolved bets.
  2. If you don’t complete unresolved bets in the given grace period, the bets will be refunded, and the casino will void any possible winnings.
  3. All plays and pays are void in the case of a game malfunction.

Microgaming introduced an interesting respin feature that makes the gameplay infinitely more interesting. It has high volatility, as well as a decent RTP. While we would appreciate a higher bet limit, the maximum win of, 5000x your bet is excellent. 

The slot has cute graphics, but the quality isn’t as crisp as expected from a slot released in 2021. However, the unique gameplay makes this slot worth trying, and we rated it 8/10.
