Expert opinion

The 3 Mad Frogs online slot from Iron Dog Studio will attract the attention of those who love nature and don't mind getting pleasure from feeding funny frogs. The reward will be big wins, the maximum can go up to x5,000 to the set bet. Multicolored frogs are actively gaining weight, absorbing special symbols in the form of coins and randomly activating the Hold & Win bonus game with awesome chances for prizes and jackpots. I particularly enjoyed the free spins, during which 2x Wild falls, doubling the line payouts.

How to Play 3 Mad Frogs slot online

The 3 Mad Frogs online slot has 5 reels in 3 rows and 20 fixed paylines. In order for a winning combination to count, you need to make a combination of 3 or more identical symbols located on adjacent reels without skips with a start from the first one. The game uses 3 types of high-paying symbols - Wild, 2x Wild and Frog, which give a multiplier to the bet x12.5 in case of appearance of 5 units at the same time. The rules are easy and clear, you can bet from 0.20 to 20 euros, free spins, Hold & Win and special symbols with special properties help to win.

3 Mad Frogs Symbols, Wild, Scatter

The Wild symbol is a lily leaf with a corresponding inscription. It substitutes for any non-special symbols. If the sequence of wilds is interrupted by a special symbol, the winnings are counted according to the pay table.

The 2x Wild symbol has a similar appearance to the Wild, but a different inscription - 2x Wild. It only falls out in the free spins round. All winning lines in which it participates are multiplied by 2 multiplicatively.

The Scatter symbol is a lily with the corresponding inscription. It appears on the 1st, 3rd and 5th reels. The simultaneous appearance of 3 symbols is a trigger for free spins.

The game involves special symbols with special properties, which become active during the Hold & Win bonus game. All of them have the form of coins with the image of a frog, you can distinguish them by color and inscriptions:

  • Special Gold Coin is golden in color, has a monetary value of x1 to x10 to the bet (in increments of +1) and x12 to the bet;
  • Special Red Leap Coin, a red coin that turns into a frog and jumps to random positions, turning the symbols there into Special Gold Coins or increasing the value of existing gold coins;
  • When hitting jackpot symbols, the red coin increases their face value;
  • Special Purple Increase Coin, a purple colored coin. Special Purple Increase Coin of purple color spontaneously generates cash equivalent and distributes it among Special Gold Coin symbols;
  • Special Blue Collect Coin in the form of a blue coin summarizes the monetary values of the other symbols on the field and stores them as its monetary equivalent;
  • Special Mini Jackpot Coin is a gold coin labeled Mini that gives a jackpot x15 to the bet;
  • Special Minor Jackpot Coin - a gold-colored coin labeled Minor, which promises a prize of x50 to the bet;
  • Special Major Jackpot Coin - a gold colored coin signed Major, which guarantees a large jackpot x150 to the bet.

In addition, during the Hold & Win bonus feature, Blank Symbols (lotus flower outlines) fall on the reels to indicate no-win cells.

3 Mad Frogs Bonus games

  • Coin Shower. A wonderful feature that accumulates coins dropped in the main game - they are grabbed by frogs of the appropriate color, sitting above the playing field. At some random moment, the amphibian is so full that spills 6 special symbols on the reels and thus triggers the bonus game Hold & Win.
  • Hold & Win. The bonus game is activated when 6 or more special symbols appear on the reels. I like this feature, it's all about luck. We get 3 respins, their number is shown by the counter. Those symbols that triggered the bonus game remain in their places. If at least 1 new special symbol falls out during the rotation, the number of respins is restored to the original number 3. All the dropped colored coins demonstrate their special properties. The cherished goal of everyone is to completely fill the playing field with special symbols, because in this case pays Mega Jackpot at a rate of x5,000 to the bet.

3 Mad Frogs slot free spins

The free spins round starts when 3 Scatter symbols appear on the reels. Luck smiled on me from the first spin: I got 8 freespins and during their realization I won the Hold & Win bonus game, which eventually brought x40 reward to the bet. Interestingly, the free spins can be activated once more while the freespins are in progress. When a round is in progress, the wilds are special - they multiply line wins by x2, and multiplicatively.
