Frog Grog is a 5 reel, 23 payline slot powered by Thunderkick. Playable from 10p to £100 per spin across desktop, mobile and tablet devices, the game is set in a science lab where magical potions can bring you fortune. It has no free spins feature but benefits from dropping symbols, a multiplier up to 7x, a burping frog and a Mystery Game.
Thunderkick slots are often quirky but they all feature superb design and animations – Frog Grog is no exception. Set in a science laboratory which wouldn’t be out of place in a Harry Potter film, there are candles and books surrounding the reels. Set inside a set of shelves, symbols on the reels include different coloured potion bottles with moths, plants and hearts inside them.
Frog Grog benefits from a Dropping Symbols feature – when you get a winning combination, the contributing symbols are removed from the reels. New symbols appear giving you the chance to win time and time for each spin. As a result, the Multiplier feature triggers with consecutive wins increasing the multiplier from 1x to 2x to 3x to 5x to 7x!
The frog symbol is the wild and substitutes for any other symbol – when part of a winning combination, you will trigger the Frog Burp feature where the frog removes all symbols on the same reel and row. The frog turns blue and becomes wild and remains for the rest of the spin or until it’s part of a winning combination.
Finally, there’s a Mystery Game feature which is played randomly when you don’t get a winning spin – all symbols except for the wild frog, flower and moth disappear from the reels thus increasing your chances of winning big. The Multiplier feature applies so consecutive wins will increase the multiplier up to 7x.
Frog Grog is certainly a little odd but it’s actually a very good game – the win potential is definitely there as you can win up to 1,616 times your stake on each spin (with the 7x multiplier of course). I consider it to be a medium to high variance game which has a lot going for it despite the lack of a free spins feature. If frogs are your thing, Novomatic’s Frogs Fairy Tale is recommended – if you like dropping symbols, Esqueleto Explosivo (by Thunderkick) is well worth trying.
