Frog Grog Slot Overview
Frog Grog is a magical brewing slot from Thunderkick. It takes you into a sorcerer’s lair. Potions bubble in a cauldron, and a grumpy frog sits on the reels. Skeletons, candleholders and old spell books surround the action.
The game plays on 5 reels with 23 paylines. Thunderkick lists a 96.1% RTP and low volatility, so wins tend to land fairly often. Its main features are Wild Frogs, a rising multiplier and a Mystery Game.
The star of the show is the frog itself. When it lands, it lets out a big burp that clears symbols from the reels. It’s not the most pleasant sound, but it can lead to some tasty wins.

Theme and Design
Frog Grog has a dark, witchy look with a playful twist. Glass bottles of blue, green and purple potion fill the reels. A moth, a thistle, a beating heart and a pair of eyeballs add to the creepy ingredients list.
Enchanting background music sets the mood. Thunderkick is known for quirky, polished games, and Frog Grog fits that style. It’s spooky without being scary, so it suits most players.
Paylines, Betting and RTP
Frog Grog has 23 paylines across 5 reels. That’s an unusual number, but it works well with the game’s dropping symbols.
Thunderkick lists the RTP at 96.1%, which is right on the online average. The game is rated low volatility. That means smaller wins come along more often, rather than rare big hits.
Our original review listed a bet range of 0.10 to 100 per spin. Check the help screen at your casino for the exact limits.
Frog Grog Symbols
Our original review listed these symbols:
- Frog: the wild, which substitutes for all other symbols.
- Moth and thistle: two of the special brewing ingredients.
- Beating heart and eyeballs: spooky mid-value symbols.
- Blue, green and purple potions: the potion bottle symbols.
Frog Grog Bonus Features
Frog Grog packs three linked features into its base game. Thunderkick lists them as Wild Frogs, a Mystery Game and an increasing multiplier.
Wild Frogs
The frog is the wild symbol. It substitutes for all other symbols to help complete wins.
When the frog appears, it burps. Our original review said the burp clears every symbol in the frog’s row and column. New symbols then drop into the gaps, which can create fresh winning lines.
Dropping Symbols and the Multiplier
Every time you land a win, the winning symbols disappear. New symbols drop down to replace them, giving you another chance to win on the same spin.
Each new win in a row raises the multiplier. Our original review said it starts at 1x on the first win. It climbs to 7x by the 5th win in a row.
Mystery Game
The Mystery Game can trigger at random when no more symbols can drop. Our original review said the frog throws symbols into the bubbling cauldron.
The removed symbols then pay out as if they formed wins, up to 5 of a kind. When the Mystery Game ends, the multiplier increases for each win it produced. It means even non-winning symbols can pay, which is rare in slots.
How to Play Frog Grog
- Check the help screen: confirm the bet range at your casino.
- Set your stake: bets ran from 0.10 to 100 in our original review.
- Spin the reels: wins pay on 23 lines.
- Watch for frogs: their burps clear rows and columns.
- Build a chain: each win in a row raises the multiplier.
Who Is Frog Grog Best For?
Frog Grog suits players who like frequent wins and unusual features. The low volatility makes it a relaxed game for longer sessions.
It’s a good fit if you:
- Enjoy quirky themes: a burping frog and a witch’s lair.
- Like chain reactions: dropping symbols can link several wins together.
- Prefer lower risk: low volatility means a steadier balance.
If you’re chasing huge wins, a high volatility slot may suit you better.
Tips for Playing Frog Grog
- Watch the multiplier: it grows with each win in a row.
- Enjoy the burps: frogs clear space for new symbols.
- Look out for the Mystery Game: it can pay even without a normal win.
- Pick a steady stake: low volatility suits long sessions.
- Set a budget: decide your limit before you start.
Understanding Low Volatility
Volatility describes how a slot pays out. Low volatility games pay smaller wins more often. High volatility games pay less often, but the wins can be bigger.
Thunderkick rates Frog Grog as low volatility. Combined with a 96.1% RTP, that makes it a fairly gentle game on your balance. It’s a good choice if you want to play for longer on a smaller budget.
Frog Grog vs Other Brewing Slots
Witches, potions and cauldrons are a popular slot theme. Most games use them for free spins rounds. Frog Grog does something different by putting all its features into the base game.
| Feature | Frog Grog |
|---|---|
| Paylines | 23 |
| Free spins | None |
| Wild feature | Burping frog clears its row and column |
| Multiplier | Rises with each win in a row |
| Special bonus | Mystery Game |
How the Features Work Together
Frog Grog’s features are linked, which is what makes the game fun. A single spin can use all three.
First, a win starts the dropping symbols and the multiplier. Then a frog might land and burp, clearing more space for new symbols. When nothing else can drop, the Mystery Game may step in and pay out the leftovers.
Each new win in the chain raises the multiplier. So the longer a spin keeps going, the more each win is worth. That’s how small wins can build into something bigger.
Who Should Skip Frog Grog?
If you love free spins rounds, Frog Grog may not be for you. It has none at all. Players chasing huge jackpots may also prefer a high volatility game with a bigger top prize.
