Casumo Casino has just added the brand new Halloween themed slot from Thunderkick to their casino title Frog Grog, in addition to this slot, they have just bolstered their range of online slots further with 3 new additions Heroic, It Came From the Moon and Majestic Sea.

The Frog Grog slot from Thunderkick uses a regular 5×3 reel layout and 23 fixed paylines, there is no triggered bonus round as such but several special features which can occur in the base to boost your wins, the special features include Wild Frog, Multipliers, Frog Burp and a Mystery Game.

Frog Grog Slot Base Gameplay

The base game uses a tumbling-reels like effect where any winning symbols during a spin are removed from the reels, unlike many other tumbling reel slots the remaining symbols do not drop into empty positions, instead the new symbols drop into the empty spaces created on the reels.

After every successive win, the multiplier value awarded to the win also rises, this is displayed on the left of the slot and can rise up to a maximum of a 7x Multiplier (1x, 2x, 3x, 5x, 7x).

Frog Grog Slot Special Features

Frog Wild – Frog Burp

The Frog symbol acts as a special Wild symbol, when it first lands on the reels any wins are paid out, the frog will then burp and clear out horizontal and vertical rows of symbols, new symbols will drop into place.

If any new wins are created the tumbling process continues and the now blue coloured wild frog remains on the reels until it forms part of any win.

Mystery Game

The Mystery game will trigger at random during base gameplay, once triggered this removes all of the lower-paying symbols from the reels leaving just Frog, Flower and Moth symbols on the reels.

Pays are awarded in a scatter style up to a maximum of 5 for any of the symbols removed from the reels and the multiplier also rises for the number of wins awarded, new symbols will drop into place and the normal tumbling mechanic resumes is further wins are created.


The Multiplier which is displayed to the left of the slot will increase after every successive win, it rises 1 step at a time during normal base games win, this process will also occur during the mystery game for every win that is created on the reels.

The Multiplier rises in steps starting at 1x then rising to 2x, 3x, 5x and finally 7x, once the top level is reached it will remain until no new wins are created.

The RTP ( Return To Player) for Frog Grog is stated as 96.1%.

Overall Thoughts on the Frog Grog Slot

The Frog Grog slot is certainly another visually great slot from Thunderkick with slick graphics and animations as we have come to expect, we definitely would have preferred a free spins bonus round to aim for, but if you are a fan of these simplistic style slots then it will most definitely appeal.

The Frog Grog slot appears to be fairly low variance in our playtests, with the top paying symbols awarding 10x stake wins, although with a 7x multiplier this rises to 70x, and the Mystery Feature and Frog Wilds seemed to occur fairly regularly to keep us interested.

Overall though not our favourite slot from Thunderkick, but certainly a decent option for wagering on, since there is no bonus round to worry about whilst playing.
