Frog Grog basic game

Frog Grog has a fun idea and atmosphere. From the name you would think that the game would involve more frogs, but instead you end up in a witch's basement. The graphics are nicely executed and the game play is entertaining in every way.

The game allows you to grab wins with various potion bottles. In addition, shelves (aka reels) display items such as a flower covered in a dome, a butterfly in its glass prison and hearts in a jar.

The game is very straightforward and easy to play, but the extra features definitely make it more entertaining and fun.

Additional features

Frog Grog has some excellent extra features that allow for some pretty big wins at best, if you're lucky.

First of all, there are respins involved. Whenever you get a win, the winning symbols fall off the shelves and new symbols fall in their place. This continues until there are no more wins. Best of all, after each win, the multiplier increases by one notch. At best, you can win up to 7 times your stake back.

There's also a wild frog, or red or blue croaker. When it appears on the reels, it removes symbols from the same row in the horizontal and vertical planes. This symbol substitutes for all other symbols and stays in place for the duration of the spin or until you get a win.

The mystery game can only be triggered on a round when there is no win. It removes all other symbols except the butterfly, flower and frog. New symbols fall in their place and the multiplier increases with each win.


The Frog Grog game has top-notch gameplay and usability, like the Thunderkick you'd expect from a game like this. You can easily play the game on your computer or mobile device, anywhere, anytime.

If mobile gaming is more your thing, just head over to the online casino via your phone or tablet's browser. There's no need to download a separate app, as the game runs directly in your browser. It is compatible with both Apple and Android devices.

This slot is overall quite entertaining and the gaming experience is always a good one.
