General Overview

Frog Grog is a Thunderkick slot with 23 fixed lines and 5 reels. This is the company’s second try at eerie themes, which has come out unsurprisingly well. Being optimised for both desktop and mobile play, the game looks beautiful across platforms and is loaded with many features, including symbols that fall from above and explode, forming new and more valuable payouts free of charge. To get to know Frog Grog better, below is the full overview, with highlights and bet settings.

Features and Bets

Following Thunderkick’s tradition, the total stake ranges between 0.10 and 100 credits regardless of the number of lines, which remain fixed. As you set it up, note that the slot is played at a medium variance and has a RTP of 96.1%.

Symbols and Bonuses

Frog Grog presents 6 potion symbols, among which are the high-paying Moth and Flower symbols, worth up to 10x the total bet. Each one needs a minimum of 3 of a kind to trigger a win, starting from the leftmost reel, as usual. To compensate for the smaller wins, all the 6 regular symbols appear stacked, or drop from the top down, creating new winning opportunities and free re-spins.

As part of the Dropping symbols feature comes the progressive multiplier. It increases one step – from x1 to x2, x3, x5 and x7 – each time new symbols are dropped in, generating more winning potential and chances at big wins. This is a typical feature among slots with the cascading feature, among classics like NetEnt’s Gonzo’s Quest, which started the trend.

Wild symbols are in the mix as well, appearing as frogs. Like regular wilds, they can substitute for the rest. However, unlike typical substitutes, they remove all symbols on the same row and column, creating free space and room for new symbols. As that happens, the frog turns blue and remains in its position for the rest of the game round or until it becomes part of a winning combo.

And that’s not all, because Frog Grog also comes with the Mystery Game. It’s a random feature and can kick in on any spin, removing all low value symbols from the screen and adding them into a boiling pot to award the player with rewards equal to each symbol count. In other words, the more of the same type of symbol you have on the screen, the more you win, based on normal payouts.


Frog Grog is a Thunderkick powered video slot with 5 reels and 23 lines with stacked symbols that drop from above. Each (Wild) win explodes, creating spaces for new symbols and increasing the win multiplier up to x7. The Mystery Game can also creep in at any time, awarding scattered payouts.
