Frog grog Slot Review

Frog Grog by Thunderkick takes you on an unforgettable voyage into the wizard’s lair. Abracadabra! And you are transported into a ‘well-equipped’ sorcery lab filled with quirky symbols including fire-breathing frogs, enchanted flowers, magical books, and potion bottles. 
The slot is set on a 5x3 grid and features 23 non-adjustable paylines. Its average 96.10% RTP and low volatility ramps up your chances of landing the 1,616x max win. The video slot offers innovative features including the Dropping Wilds and Increasing Multipliers, as well as other interesting features which we’ll be talking about shortly.

Frog Grog Theme and Graphics

If there’s one feature that sets Thunderkick slots apart from others, it has to be the sheer quality of the visuals and animation. Frog Grog is no different in this regard. The slot backdrop is set in a sorcerer’s lair, and the reels are set against a row of wooden shelves with a large cauldron at the bottom.
In line with the magic theme, the icons are inspired by occult symbols such as the frog itself- a popular ingredient in potent potions, coloured potion vials, flowers and a caged moth. Close to the reel, you’d find a wooden chest with a magical spell book and other artefacts like keys, candles, and bird cages. The soundscape is upbeat and when spinning the reels, you might hear a villain laughing, but there’s nothing to worry about. Perhaps.

7 Major Slot Symbols and Their Features

Frog Grog features 7 main symbols- the wild, the caged moth, thistle, and four coloured potion bottles. There are no scatters in this game.

The wild is represented by an orange fire-breathing frog, and it can substitute for other symbols in the game. When you land a winning combination, the frog spouts fire and takes out all the signs along that column and reels. The wild is then stuck to that position throughout the game, or until it is part of a winning combination.

Moth in a jar
The caged moth is the most valuable symbol in the game.

Coloured potion vials
There are 4 different coloured potion vials in the game- red, blue, green, and purple bottles, all are low-value symbols.

Enchanting flower
This is represented by a thistle enclosed in a jar, it is one of the higher paying symbols in the game.  

Frog Grog Paytable: Symbols and Multipliers

With 3, 4, or 5 moth icons you can earn 0.8x, 1.7x, and 10x your stake. The thistle rewards you with 0.6x, 1.2x, or 6x your stake for a combination of 3, 4, or 5. The potion vials are the lowest paying symbols, offering between 0.2x and 3.5x your bet for a combination of 5. 

Frog Grog Slot RTP and Volatility

This slot has a 96.1% RTP which is average for a video slot and considered appropriate for experienced players. It has low volatility which means that you stand a chance to claim frequent wins when you play for real money. The max win can be as high as 1,616x which is not the highest we’ve seen but is certainly worth something.   

Frog Grog Bets and Paylines 

Frog Grog is set on a 5x3 grid and offers 23 non-adjustable paylines displayed on the paytables. To view the paytables, click on the Menu tab on the left part of your screen. Unlike other slots where the paylines can be adjusted, this one features 14 different bet amounts and the bet size ranges between $0.10 and $100. 

Special Bonus Features and Combinations

Frog Grog features a number of special features that tilts you closer to that 1,616x max win.

Dropping Symbols
If you have ever played slots with cascading reels, then you should be familiar with this feature. Once the frog symbol appears on the reels and starts to burp, all the symbols in the row and column are replaced with newer signs, increasing your chances of landing a juicy win.

Frog Burp
The frog wild can replace all other icons in the game. The Frog Burp feature is activated once the frog icon is part of a winning combo. Once triggered, the fire-breathing frog razes down all other icons on the same column and row, and then the colour transforms into blue. The blue frog then remains in place till the round is over or till it is included in a winning combination.   

Mystery Bonus Round
As the name suggests, the mystery symbol is triggered at random. Once triggered, the reels become neon blue. After all the icons have dropped on the reels, they all disappear again, leaving only the wild and high paying symbols- like the moth and thistle. Even better, you are rewarded with the equivalent payout amount for the signs that were replaced. Here’s how. If there are five red potions close to other icons before the Mystery Round is triggered, you earn 3.5x your total bet. The same payout for creating a combination of 5 red vials. This applies to other icons in the game.

At the leftmost part of the reel, you’d find a vertical neon pink counter that displays 5 multipliers- 1x, 2x, 3x, 5x, and 7x. The multiplier moves one step higher for every win landed during the Mystery Bonus Round.

What We Think About Thunderkick’s Frog Grog

Although there are no scatters or free spin features, Frog Grog is still quite entertaining. In addition to the attractive bonus features, the graphics, soundscape, fair 96.1% RTP and low volatility make your voyage into the wizard’s den more exciting. Take note that the highest value symbol is just 10x your stake, which is quite low. However, the developers make up for this with the 7x multiplier that increases your chances of landing the 1,616 max win.

Until recently that is. The year 2016 is seeing much more activity from this game provider, with already several new games released, but hardly any one of them making a bit hit as yet. I am a great fan of Thunderkick games, Fruit Warp made me as such, but there hasn't been any new game that comes even close to it as yet. Personally, I think Thunderkick is being too timid by staying in their 'comfort zone', never daring to take any high risks, never daring to come up with a good high-paying game, or one that can keep any player's interest going. Thunderkick is 'moving too cautiously'. Isn't it time to 'start living dangerously'? Yeah, I agree with Nick Jonas when he sang those words in his song 'Eat Cake By The Ocean'.

Frog Grog is one of these latest releases from Thunderkick. The graphics are simple and nice, appearing differently from the usual, a typical Thunderkick trademark which I do like, but sad to say, it still isn't perfect. The active icons are a little bit too small, as compared to the win multipliers to the left of the play area, which are much too big unnecessarily. And there's too much of the background scenario too, which aren't doing much. The Play area should have been the top priority and be given more viewing space than it currently is.

The Frog is the Wild symbol, appearing first in orange, then turning blue after clearing some symbols, but is an absolutely dumb Wild symbol which doesn't pay for itself, doesn't double any wins, doesn't become stacked, doesn't expand, but only to substitute for all other symbols. What a waste of Wilds! And what a waste of winning chances for players too! Why the designers have to do this, I just cannot figure out. But then again, most of their games are like that, hence they cannot be big hits. When orange in colour, and after winning symbols have been paid for, the frog would burst out its flame to clear all symbols on the same row and column, letting new symbols drop into the vacated positions, for new winning chances. It's called 'Dropping Symbols', as opposed to 'Rolling Reels', because the reels do not roll down in this game, only new symbols would drop down. Some may like this, some may not, but I personally feel that rolling reels have more advantages.

There are no Scatter symbol and there are no Bonus symbol either. The only special feature in the game is the Mystery Game feature, randomly activated with any non-paying spin. All symbols would be removed from the play area, getting paid for each of them, except for the Frog, Flower and Moth symbols, which would remain. New symbols would then drop down into the empty positions and any new wins are then paid. Wins with up to 7x multiplier are possible. The other symbols in the game have very low values, which I don't like at all. The highest paying symbol is the Moth, paying only 10x the total bet for 5 of them. The Flower pays 6x, the Heart pays 3.5x, and the rest paying from 3x down to 2x the total bet for 5 of each kind. Sheesh! With such a very low paytable, coupled with the 23 fixed paylines, no big wins seem possible at all!
