Frog Grog Video Slot Review By Thunderkick Frog Grog video slot is available at Vera&John Casino and powered by Thunderkick software. This online video slot has 5 reels, 3 rows and 23 paylines and is available on desktop, mobile and tablet devices.
The slot is set in a science lab with lots of bottles of potions. I found the images pretty boring overall, they all looked very similar. There is also no free spins feature, however there is a mystery game, multiplier and a frog burp feature. The reels do not spin in the usual manner and the symbols drop from above. The symbols are of different bottles and colours of potions, the moth, the flower and the frog, which is the wild symbol. When the symbols drop from above and there is a winning combination, those symbols will disappear and more will drop down to replace them. There is a multiplier which increases one step each time new symbols are dropped in. The wild frog symbol substitutes for all other symbols. After wins have been paid, the frog will remove all symbols on the same row and column, except other frogs and it will then remain for the rest of the game or until it is part of a winning combination. The mystery game is triggered at random when no new dropping symbols can occur. The mystery game removes all symbols except for the moth, the flower and the frog. Symbols that are removed will award prizes according to the paytable up to a symbol count of 5. The multiplier will increase one step each time new symbols are dropped in. After the mystery game is finished, the multiplier increases one step for each win during the mystery game but does not increase beyond the final multiplier. Overall I found this video slot boring and it is not one that I will play again. I have to admit that the multipliers are quite good and I really did like the colours of the images.
