Frog Grog is an online slot by Thunderkick. The game, which uses a 5×3 layout with 23 paylines, is set in what looks like a witch’s cabin with shelves of different coloured potions and vials. The reel itself acts as the shelves and with each new spin, the potions and vials, the slot’s symbols, disappear and are replaced by new potions and vials that drop from the top of the screen.

Frog Grog is pretty popular among Thunderkick fans due to its high-quality visuals, unique theme and fun gameplay mechanics. If you want to find out more, just continue reading.

How To Play

Before you can visit the witch’s cabin to brew some potions, you’ll need to register and deposit at an online casino offering the game, which we touch on at the end of the review. Once you’ve done that, you can launch the game and adjust your bet by clicking the casino chip and then a pre-determined amount or you can hit the spin button and kick-start the game.

In addition, you can also enable the autoplay feature, allowing you to select the number of times you want the reels to automatically spin.

Special Features

Frog Grog

The Wild symbol is represented by a frog. It substitutes for all symbols and when it lands, the frog symbol will display any winning combinations before removing all symbols from the same row and column and will stick to the reels until it forms a winning combination. However, a frog symbol cannot remove another frog symbol from the reels, even if they share the same column or row.


Frog Grog has a multiplier feature where each successful combination increases the multiplier by one point. When you land a winning combination, your multiplier will increase by one point and for each subsequent winning combination before the next spin, your multiplier will continue increasing from x1 to x2, x3, x5 and finally x7. However, each new spin resets the multiplier counter.

Mystery Game

You can randomly trigger the mystery game on an unsuccessful spin. When this happens, the Mystery Game removes all symbols except for the moth, flower and frog. The symbols removed will pay out according to the slot’s pay table, providing you with a guaranteed win.

Frog Grog’s Multiplier feature applies during this bonus round so players can make some big wins!
