How to Operate the Reels and Play

Before discussing the game mechanics, we need to look at the different key symbols and bonuses that you can win.

  • Wild – the golden skull symbol is the wild icon. Unlike other slot machines, it does not randomly appear on the reels. It works in conjunction with another symbol called the Mystery Symbol. The wild replaces other symbols automatically. It changes to a symbol that can possibly create a combo. Now, if you are lucky enough to turn the symbol into a wild one, all the symbols from the first reel on the same row will turn into wild. So, if you have a Mystery symbol on row one, third reel that morphs to a wild, the symbols on the first and second reel on the first row will change and get replaced with wild symbols, making it easier for you to create winning combos.
  • Scatter – the scatter is the golden keyhole. If you manage to land this three times, one for reel 1, 3, and 5, you will receive eight free spins. The free spins will automatically trigger, which means you cannot accumulate them.
  • Mystery Symbol – it is represented by the golden grimoire, and it lands randomly on reel 3, reel 4, and reel 5. If you land it, it will transform to either a wild or another symbol. If you have several of these symbols, all of them will transform into the same thing. If the mystery symbol transformed into one that is the same as the first symbol on that particular row, all other symbols from the first row to the one that changed will become the same.
  • Free Spins – while playing the free spins bonus, the Golden Grimoire free slot machine will spin eight times. Each spin has no cost to you, but it will use the same bet amount that triggered the free games. During this round, you may also get a chance to land the mystery symbol that will stick on the grid.
  • Sticky Feature for the Mystery Symbol – this can only appear between reels 2 and 5 in the free spins round. It is the same mystery symbol, but it will stay in its position until the free spins are gone. Also, this symbol can transform into a different symbol on every spin.

To play Golden Grimoire slot online, you must first select the value of your coin. You will find this control button at the bottom right of the grid. You can choose between €/£0.01 and €/£2 per coin.

The next step is to choose how many coins you are willing to risk. The Level button is the one you have to use to make this change. It is found at the bottom left. The maximum you can bet per spin is 200 coins.

Despite the slot Golden Grimoire slot machine having 40 pay lines, it will only charge you with 20 lines. In terms of currency value, below is an example:

  • Coin Value = €/£2
  • Level = 10 coins per line (200 coins total bet)

In this case, the total bet for the round is €/£400. But if you switch the coin value to the lower one, for example, €/£0.05, the number of coins you bet will remain the same, but it will cost you only €/£10 (200 x 0.05)

The next thing to do is to spin the reels and wait for your luck.

Game Payouts and Winning Combinations

In the game, you will win a prize or coins, if you successfully manage to land at least three symbols of the same kind from left to right. The symbols must be on adjacent reels. If you land three same symbols, but they start from the middle reel, you will not win a prize. They have to start from the first reel. All the values of the symbols are found in the game paytable. The payouts are shown in coins, not currency. These values must then be multiplied by the bet level.

Number of Appearance in a Pay Line SYMBOL
Red Gem Green Gem Blue Gem Purple Gem
5 100 75 40 30
4 30 25 20 15
3 10 8 5 5

Here is an example of a win. If you landed three Red Gem symbols on a pay line, and you wagered €/£2 as coin value at the Bet Level 2, your total win is 20 coins (10×2). Since each coin is valued at €/£2, the money that will reflect on your balance as a win is €/£40 (€/£2 X 20 coins).

One of the tips that you can implement in a game like this is to wager an amount that you can maintain consistently for long play. What you want is to make sure that you give yourself a chance to spin more times, and then eventually land the scatter symbol and the golden grimoire symbols. These are the two symbols that can significantly improve your winning odds.

This slot machine has a low to medium variance. What this means is that it is difficult to land a huge win, but smaller wins are quite regular.

Playing Golden Grimoire Slot Online for Free and for Real Cash

You can play for free with the demo version that you can access from our site, and you can use this opportunity to practise and then devise a strategy before you invest real cash. The demo version is completely free, and no registration or download is required.

If you want to play free Golden Grimoire slots with real cash, you can choose from our list of casinos that offer this game. Before you start playing with real money, you have to register at a casino and add your payment details. Once you complete your first deposit, you can start spinning the reels of the Golden Grimoire. Moreover, you can get a nice welcome bonus from the casino.

It is also best if you first review the casino’s policies, such as what payment methods are accepted, what countries players are accepted, and if they have bonuses. Should you decide to take advantage of a bonus, you must carefully read the terms and conditions of the promotion before you opt-in.

Mobile Compatibility

To play on mobile, you need to access the game either from a demo version or from a casino website. The game has no app, and you have to launch it from a browser. Some casinos, however, require that you install their app. In that case, you have to do that. The Golden Grimoire casino slot machines are accessible on all types of devices, provided that a web browser is used.


The Golden Grimoire slot machine makes it tougher to land a wild symbol, considering that the titular symbol can transform into anything like low or high-value symbols. But when it does, you get more rewards than in an average slot machine that lands wilds randomly.

One great thing to look forward to is the scatter symbol, which gives you eight free Golden Grimoire slot spins. During this round, the mystery symbol sticks in its position. After that, it changes in appearance or symbol at every spin, giving you more chances to land a win.

The game also offers players a variety of options on betting. The coin sizes are flexible enough, and you can also adjust how many coins you want to bet per spin, thus also increasing the value of your wins.
