Frogs and science are tied at the hip, as kids have dissected the reptiles for decades, learning about their ooey gooey insides and ability to make girls shriek. The Frog Grog slot by Thunderkick is a game that ties in with this, as you're working in a crazy scientist's lair to concoct some potions to help build your bankroll. The game has a great theme that's dark without being scary, and the features are simple but give it some staying power.
Frog Grog is a 5 reel, 23 payline video slot that takes place in the scientist's lair. The game sees you mixing frogs with other potions in order to create some winning potions. The game has a giant pot in front of you, with various potions on a shelf making up the reels. The game's symbols include a blue potion, green potion, purple potion, red potion, plant in jar, and butterfly in cage. You'll also find a color changing frog that serves as the game's wild symbol. This wild sees the frog belching fire to clear the reels, giving you a chance to win more prizes.
The features in Frog Grog include the wilds mentioned above as well as cascading wins, which you see in a few slots every now and then. The cascading reels replace the game's winning symbols on a spin with new ones on a re-spin that doesn't cost you any extra money. Unlike most of these games though, symbols stay in place rather than falling down, which makes this feel different from most similar games I've tried. There's also a mystery game that pops up randomly and pulls the low-paying symbols and pay you for them, boosting the win multiplier in the process, before you're given the re-spin. These features combine to give Frog Grog a posted return to player percentage (RTP) of 96.1%, which is average for an online game.
The overall experience is good with this game, as the look is nice and the cascading reels will keep you sticking around for a while. I found that the game plays perfectly on the smaller screens of smartphones and tablets. It does also look really good on your regular computer screen, and is immediately accessible. If you're feeling magical and looking for a chance to boil some frogs, then Frog Grog is a game that's well worth your time and money.
