There is quite a few mad scientist themed slot games on the market, and now Thunderkick is adding to that list with their latest offering, Frog Grog! If you love being transported to a magical world full of potions and spells, this could definitely be the game for you. Could you cast a magic spell that will result in some big cash wins? It really is entirely possible with this fun and bright slot game that features lots of cool bonus features that will help you cast that all-important spell.

Our Verdict:

Frog Grog is a game for every slots player to enjoy as you can get started mixing potions in the lab for just 10p per spin and this rises up to £100 per spin. This is certainly an eye-catching game as you'll be transported to the lab with different coloured neon potions in the background. The 5 reels, 3 rows, and 25 fixed paylines are slightly different in this game as they look like shelves in the lab, and on these reels, you'll find lots of symbols that will grant you big multipliers in the Dropping Symbols feature.

Wild Symbol:

Nearly all online slot games feature a wild symbol, which is always a welcomed added feature to a game as it replaces nearly all symbols on your reels to create big winning combinations. In the slot game Frog Grog, the wild symbol is the wild frog himself, and you cannot miss him when he lands as he is almost neon in colour! This frog wild will replace all other symbols to create more winning combinations. What's more, in this slot game he will take away all of the symbols in the row and column that he lands on for more symbols to fall into their place.

Dropping Symbols:

The Dropping Symbols are always a fun feature when playing slot games and go down a treat with gamers which is no surprise considering it can bag you lots more wins. When you are lucky enough to land a winning combination on your reels, the symbols that are part of that winning combination will then be removed, and new symbols will take their place as they fall down from the top of the slot game. As these symbols drop down onto your reels, you can then create more winning combinations, and this will carry on until you are out of winning combinations.

Mystery Game Feature:

The great thing about Frog Grog is that even if you don't get a winning spin, you may still be in for a treat which doesn't happen too often with online slot games. Each time you are unlucky and don't get a winning spin, the Mystery Game feature will be randomly triggered, and all of the symbols on your reels, excluding the moth, flower, and wild frog symbol are taken away from your reels. This means that new symbols can replace these lower value symbols and you will hopefully bag yourself some more high value winning combinations!
