Theme and basic information

The Griffin’s throne slot was released in 2020 by the big famous company IGT that is well-known on the market. The slot has a very attractive design, and its theme refers to Ancient Greek mythology. The perfectly-implemented animation looks impressive and, I suppose, an unusual interface makes players more involved in the gameplay process.

Likewise, it has a very lucrative maximum possible winning that equals 25,000x and some fascinating features that I will elaborate on below.

As for the theme, it is not extraordinary, but it is made with a new vision and it makes the slot, I’d say, special.

In the middle of the screen, you will be able to see a mythical creature that is half an eagle and half a lion, it is actually called the Griffin. It is the main character of the slot. Besides this creature, there are some attributes of the Ancient Greek mythology represented including a helmet of an unknown warrior, a sword and a shield, a magnificently-looking temple, an ancient pitcher and the sun.

Game play

Initially, this slot has 5 reels and 4 rows, but the number of reels and rows can be changed up to 5 reels and 12 rows if the Sun Scatter lands on every reel at the same time.

There are 30 paylines in the slot, and this amount can be changed as well. It can be set up to 90 active paylines which can bring you quite a big possible winning if you will be lucky enough.

The line wins pay from the left to the right side. And the line wins will be multiplied by coin value during the gameplay.

The total bet can be adjusted depending on your preferences. The minimum bet size is 0,75 euros and maximum bet can be set to 2250,00 euros. So that this slot doesn’t offer appealing variants for those players who love to make small bets, though highrollers will be fully satisfied by offered options.

Slot symbols

There are 11 paying symbols in this slot and 3 special ones like Wild, Scatter and the Sun symbol that triggers a 12-row height reel. The highest paying symbol has a picture of the Griffin.

The lowest paying symbols are almost all royals except for Ace that pay up to 50 coins on one win line. The Scatter symbol has its own particular reward that can be considered the lowest one and it equals up to 20 coins in the case you collect all 5 Scatter symbols on the reels.

So, the highest win per line equals 125 coins or 1.66x your bet, which is not the best possible result, but it is fairly appropriate for satisfying gameplay experience.

The Wild symbol looks like a sign Wild on the purple background. As usual, it substitutes for all symbols except the Scatter and the Sun symbols.

The Scatter symbol, in its turn, has a picture of an ancient Greek temple on it. And its wins are multiplied by total bet. As I’ve mentioned, the Scatter has its own scale of rewards that you are able to find in the Paytable tab of the game.

Slot Bonus features

If 3 or more Scatters appear on the reels you will be awarded by Free spins. In case it happens in the base game you will get 10 free spins.

During the free spins round, the number of paylines and the height of the reels will be increased. So, there will be 90 active paylines and 12 symbol-high reels in the Free spins bonus round.

While the Free Spins Bonus round is active, the free spins can be retriggered if two or more Bonus Scatter symbols appear on the reels:

  • you will get 3 additional free spins if the number of landed Scatters equals 2

  • you will get 10 additional free spins if the number of Bonus symbols landed equals 3,4 or 5

It is said in the rules that free spins are played at the same coin value as the triggered spin.

A special bonus game is not offered in this slot.

Special features

The Multiplier feature that is triggered by one or more Sun symbols can be considered a special feature. In this case, the reel on which the Sun symbol is landed transforms into 12 rows/symbols high Golden Pillar.

The Sun symbol can land on all 5 reels at the same time. Consequently, the grid can become 5x12.

It is said in the rules that the Golden Pillar reels contain Wild symbols and 2x, 3x, 5x and 10x multipliers only. Multiplier symbols are wild and substitute for all symbols except Bonus, Sun, Wild, 2x 3x, 5x and 10x. The reels automatically respin once. After the respin in the base game, a number of symbol positions corresponding to the total number of Griffin, Wild, 2x, 3x, 5x and 10x symbols on the reels may transform into Wild symbols. Random Wilds can land on positions not containing Griffing, Wild, 2x, 3x, 5x or 10x.

During Free Spins Bonus that happens after the Multiplier feature, 6 to 13 symbol positions may transform into Wild symbols. And random Wilds can only appear on positions not containing Griffin, Wild, 2x, 3x, 5x or 10x symbols.

2x, 3x, 5x and 10x substituting in a line win multiply that win by 2,3,5 and 10 respectively. If more than one multiplier symbol substitutes in a line win, that win is multiplied by the sum of the awarded multipliers.

The full information regarding the Multiplier feature is given in the game rules.

There is no progressive jackpot in Griffin’s Throne slot.

RTP and volatility

The RTP of Griffin’s throne slot has a range of possible coefficients that can be set individually by a casino itself. So, it ranges from 93% to 96.05%.

It is very important to check an RTP level of this slot before you start to play, because 96.05% is an appropriate coefficient for safe game play and 93% is a questionable choice, it is much less than the average level on the market.

The volatility of this slot is medium-high, so it means that the big payout will be given with lower frequency.

The hit frequency of Griffin’s throne slot is unknown.

Graphics and sound

The graphics of the slot is quite remarkable. It looks unusual and memorable. The unique-looking Griffin and slot’s grid make us more involved in the game play.

The sound effects also have top-notch quality.

So that, I’d say, that the graphics and sound add just positive emotions to the general experience of a player.


I’m going to elaborate on the pros and cons of the slot.

The pros of the slot include:

  • nice animation

  • high-quality sound

  • big possible winning

  • big free spins multiplier

  • html5 is supported

The cons of the slot include:

  • ranging RTP level that can be set from 93% to 96.05% which is a very low level

  • not unique theme

  • medium-high volatility

In my opinion, Griffin's throne is quite an interesting slot with some extraordinary features and good implementation that was created with the help of new technologies. Moreover, it offers a big possible win and engaging free spins multiplier. But the slot has a couple of disadvantages which are a quite low RTP level and high-enough volatility.

So that I would recommend this slot to those of players who love risky games with a big possible winning.
