“What A Delicious and Gruesome Grog, Let’s Feed it to the Clueless Frog” ~ Thunderkick

Frog Grog is a 3-row, 5-reel, 23-fixed payline slot. Its symbols consist of colourful potions, moths, flowers, hearts and frogs, and they all appear to be sitting neatly on a wooden shelf. Glowing Multipliers (1x – 7x) line the left side of the screen. An enormous cauldron with glowing yellow grog rests just beneath the shelf. The potions themselves give off an eerie glow lending to the overall mystical mood. Frog Grog’s graphics quality is what we’ve come to expect from Thunderkick’s 3D slots – stunning! Like many Thunderkick slots, Frog Grog displays cash values for Balance, Win and Total Bet at the very bottom of the slot screen. The bet options are simple and straightforward. Select a Total Cash Bet ranging from 10p – £100 at LeoVegas online casino. Frog Grog’s Paytable lists potential wins in cash as well. These values change to reflect the Total Cash Bet selection allowing players to see how much cash there is to be won.

All of this online slot’s 7 symbols reflect the theme. The only special symbol is a Frog Wild which can substitute for any regular symbol, however, it cannot form its own winning combinations. It is also integral to the Wild Frog Feature. Frog Grog’s 6 regular symbols, listed in order of highest to lowest value, include: Moth, Rose, Heart in a Jar, Eyeballs in a Jar, Green Elixir and Blue Elixir.

Wild Frog Burp FeatureFrog Grog’s gameplay is left to right along 23 paylines. That’s 23 ways to win. Get 3+ of any regular symbol, starting from reel 1, to win. To profit along a single payline, get 4+ Roses – Moths or 5+ of any regular symbol. While that may sound rather low when compared to some other slots, keep in mind that Frog Grog’s Bonus Features work to boost wins. Multiple wins along differing paylines are allowable which also boosts those numbers. Total wins are displayed in the ‘win box’ beneath the reels.

The highest paying regular symbol is the Moth which awards a pay of (80p, £1.70, £10) for a Total Cash Bet of £1. This symbol gives Frog Grog the potential to award up to 10x the Total Bet for a 5 of a kind match. That can be as much as £1.000 when the max bet of £100 is selected. The next highest paying symbol is the Rose which awards a pay of (60p, £1.20, £6) for a TB of £1 potentially awarding as much as £600 for a 5 of a kind match. According to Thunderkick, the max prize for Frog Grog is 1616x the Total Bet which amounts to as much as £161.600 when the max bet is selected.

Frog Grog Bonus Features

Dropping Symbols & Win Multipliers: In similar fashion to the online slot Esqueleto Explosivo, winning symbols disappear and new symbols drop down from above. Each consecutive win raises the Win Multiplier (1x, 2x, 3x, 5x, 7x), that can be seen left of the reels, by 1 step. That multiplier is then applied to the next consecutive winning combination.

Wild Frog Burp Feature: The orange Wild Frog burps removing all symbols that share the same row and reel. It transforms into a blue Wild Frog which remains in place until either it is part of a new winning combo or the round ends.

Mystery GameMystery Game: This Feature randomly triggers during gameplay at the conclusion of a round. All symbols, except for the Roses, Moths and Frogs disappear. The removed symbols are matched up awarding wins of up to 5 of a kind.
