Frog Grog Online Slot

Bookmark

A magical science lab or that of a mad scientist is always an excellent setting for an online slot, and that is exactly what this 5-reel, 23-payline slot from Thunderkick has to offer. The lab may be a bit eerie, but the winning potential that the game offers is certainly far from creepy, and definitely not something you’d want to run away from.

Set in a science laboratory, this 5-reel, 23-payline slot from Thunderkick may not have a bonus round, but has a couple of interesting features that set it apart from other slots. The laboratory that serves as the setting for this quirky slot is one you won’t be surprised to see in a Harry Potter film.

Candles, books, skulls, and empty bird cages all add to the eerie atmosphere of the slot. The slot may be a bit odd, but it certainly offers excellent winning potential. Mix magical potions until you find the perfect combination that will have you winning a huge payout. You can play the game on all desktop, mobile, and tablet devices.

Gameplay begins with setting your bets. You may start by clicking on the button with the number 1 on it. This allows you to set the amount you want to wager on every spin from 0.10 to 100. You may then set the reels into motion by clicking on the Spin button at the rightmost end of the control panel. For a chosen number of uninterrupted spins, click on the button in the middle. You may set 5, 10, 25, 50, 75, 100, 250, 500, 1000, 5000 automatic spins.

Feature Symbols

You will not see any of the familiar playing card symbols in this game, as all base game symbols are theme-related. There are only six standard base game symbols in this slot. They are represented by a green potion, a blue potion, a pair of eyeballs preserved in a jar, a heart in a jar, a flower swaying inside a jar, and what looks like a firefly inside a glass container.

The game’s Wild symbol is represented by the frog itself. This symbol can substitute for any of the other base game symbols to help you land winning combinations. Other than that, the symbol also removes all the other symbols in the row and column on which it lands, and other symbols will fall into place.

Bonus Rounds

One of the slots most interesting features is the Dropping Symbols feature. Instead of the usual spin of the reels, the symbols that form a winning combination all drop from the reels, and new symbols drop into place from above the reels. This gives you a chance to land more wins without betting more money, and the symbol drop process continues until there is no longer any winning combination formed.

The feature even has an added bonus: The multiplier for all winning combinations you land will increase with each new drop, up to a maximum of 7x.

The game also has a Mystery Game feature. This bonus feature is randomly activated on every non-winning spin. All standard base game symbols will be removed from the reels, with the exception of the flower, firefly, and Wild symbols. This gives you a much better chance of landing high-value wins, with only two high-value symbols and the Wild left on the reels.
