Frog Grog gameplay and paytable

There are only six symbols in the game. Four potions – Blue, Green, Purple and Red pay around the same amount, and the remaining two symbols pay well. The flower is twice as valuable as Potion symbols, and the Moth is the most precious symbol in Frog Grog.

Frog Grog is played on a 3×5 reel set, and at the heart of this game are the falling blocks mechanics. Every time you land a win, the winning symbols will disappear and will be replaced by new ones.

At the same time, the win multiplier will increase. There are five multiplier levels so you’ll need four wins in a row on the same spin to reach the maximum multiplier of 7x which will then be in effect for the next re-spin.

What’s unique about Frog Grog is that, compared to other falling blocks games, here the symbols don’t fall, but the vacant spots are instead replaced directly with new symbols. This reduces the flexibility of the board a bit, as you’re stuck with positions you initially got – unless you remove the symbols by forming a new winning payline.

There’s a Wild Frog symbol that substitutes for all other symbols. After presenting all payline wins, the Frog will remove all symbols on the same row and column except other Frogs and will remain in its place until the end of re-spins or until it forms a winning payline.

Mystery Game Bonus Feature

Apart from the re-spins and multipliers, there’s a bonus feature in Frog Grog that adds to the fun. It can get triggered randomly on any non-winning spin. The Mystery Game removes all symbols from the board except for Moth, Flower and Frog.

The symbols that are removed award wins according to the paytable, up to a symbol count of 5.

This feature won’t make you wealthy, but it’s an interesting addition to an already fun game.

CasinoWizard’s verdict: 3 out of 5 stars

Frog Grog is a fun and well-balanced game that will appeal to all falling blocks slot game fans and might attract a new fan here and there. Graphics are excellent and so are game mechanics, so there’s nothing not to like about Frog Grog.

The game offers the potential of a big win, and the big win can happen anytime, you just need luck with re-spin wins, and you’ll be on your way to the maximum multiplier.
