Frog Grog is one of most original and creative titles released by Thunderkick is some time. This slot is themed on a witch’s lair and contains 5 reels and the unusual number of 23 paylines for you to play with. The slot also offers up a rather nifty set of graphics and animations, with the reels themselves represented by cabinets of potions. Frog Grog can see players able to bet anything from a floor of just 10p per spin, although if they wish to push the boat out, players can wager as much as £100 a spin on this game. The top prize is fixed at 1,000 coins, and in order to win it, players need to line up 5 of the butterfly potions on any payline in the game.

Special features

This is a slot which contains a Dropping Symbols feature. The feature can see any winning combinations you encounter disappear from the reels, with those symbols replaced by new ones. An increasing multiplier can be added to every consecutive win you pocket, resulting in wins being magnified by 1x, 2x, 3x, 5x, or even 7x the normal rate of pay.

Frogs are wilds and can replace all other symbols in this slot. There is also a Frog Burp bonus, which can see all symbols on the same row or reel removed, and become wilds for that particular spin.

Bonus features

A Mystery Game bonus can be triggered at random in this slot, particularly after a non-winning spin. It is not guaranteed to occur after every non-winning spin, though. When this feature is triggered, players will find that all symbols save for frogs, flowers, and moths disappear from the reels, boosting your chances of landing a win.


This is certainly and creative and inventive slot. Due to the presence of the Dropping Symbols feature, there is no free spins bonus in this game. That is hardly the end of the world, though. Frog Grog seems to be remarkably fine without one, and the slot is still very much enjoyable.
