The game has a magic-inspired theme with the background showing a candle-filled laboratory full of books of spells. The symbols on the reels are all theme-related and feature an array of brightly colored potions filled with eyes, hearts, plants, and moths. The wild symbol is a frog and it can substitute for all other symbols. Whenever a wild is part of a winning payline, the frog will burp and remove all the symbols from the row and column it appears on. The frog will turn orange and remain in place until it forms part of a new winning combo or for the rest of the round. 


Frog Grog has one main special feature. This is the  Mystery feature that triggers manually when no new dropping symbols would otherwise occur. During the Mystery game all symbols except the moth, flower, and wild frog, are removed. The removed symbols awards scatter wins according to the paytable up to a symbol count of 5. As this happens, the Multiplier also increases one step for each win during the Mystery Game. So wins can be worth up to 7x more. And since it’s triggered without a will, it’s the best when the mystery feature kicks in when the game is at the highest multiplier.
