Frog Grog Slot Review

Frog Grog is a nice and nifty new slot machine which has been released by Thunderkick. The slot is all about witchcraft, and wizardry, lotions and potions, frogs and fantastic fun-filled gaming. Frog Grog is a wonderful 3D slot machine, with plenty of awesome graphics and animations abound.

The 5 reels themselves are designed as a bookcase which holds 15 vials of frog grog (whatever that happens to be), sitting before a vat of bubbling liquids. Ideally timed for a pre-Halloween release, the question is whether Frog Grog will turn out to be a trick, or a treat?


Thunderkick started up in 2012, and they are one of the smaller casino software developers you will find online. That being said, they are rapidly gaining popularity and are known for their stunning 3D graphics, awesome animations, and out-of-the-box thinking when it comes to slots.

Each game which has been developed by Thunderkick contains stuff you probably won’t have seen before, or that are new to Thunderkick games. That all adds up to make their slots quite unique from one another. Frog Grog is in much the same vein, with its magical multipliers, and dropping symbols.


How to play

Located below the vat and the bookcase-style reels are the wagering menu bar. Rather disappointingly, it has not been designed in accordance with the rest of the slot. It is not thematic in the slightest.

However, the menu bar does allow you to choose total bets which stem from $0.10 per spin, up to $100 per spin. Curiously enough, there are 23 paylines on the reels of this slot machine game, but the wagers don’t equate to the number of lines you play with.


Dropping symbols: Frog Grog features an avalanche reels style structure. This means that when winning symbols appear on paylines, they will be removed from the reels (after paying out their prize) and replaced by new symbols.

In this manner, it is possible for players to bag multiple winning combinations with just a single spin on the reels.

Multipliers: With each new winning combination you bag with the multiplier feature, you will bag an increasing multiplier. Landing 1, 2, 3, 4, or 5 wins in succession can see you pocket 1x, 2x, 3x, 5x, and 7x multipliers on those wins, respectively. The multiplier resets when you no longer win.

Wild symbol: The frog with the “W” across his chest acts as Frog Grog’s wild icon. It can substitute for all other symbols in the game, without exception. As far as wilds in online slot machine games go, this one is pretty drab and dull. Is it your basic wild, nothing more, nothing less.

Mystery Game: It is entirely possible that when no new symbols appear on the reels, that a Mystery Game may be triggered. In this feature, all symbols apart from the moth, flower, and frog icons are removed from the reels, leaving you with bigger wins to snap up.

Maximum pay-outs

As good as those special symbols can be, none of them can reward you with considerable wins. In fact, in order to bag those wins, you are going to need to land the moth icons on the reels.

They are the best paying symbols in the game, and can see you pocket as much as 10x your total bet, if you can land 5 of them on any active payline. The biggest drawback with this slot is that the non-progressive jackpot doesn’t really seem to justify the expense of making bets on the game.

Fortunately, the regular wins in this game occur often enough that you aren’t relying solely on a jackpot win to make your fortune.


Frog Grog is quite different from many other Thunderkick slots as we’ve said. It has a multiplier and avalanche feature which makes this Thunderkick game go with a bit more of a – well, a kick actually. All the same, the jackpot is petite and that is troublesome for some players.

You can find this new slot machine at all good casinos offering Thunderkick software. Many NetEnt powered casinos tend to offer Thunderkick software, too, so they could be worth checking out if you wish to play the Frog Grog slot.
