Expert opinion

I tested the Mad Cabs Hold & Win online slot from Iron Dog Studio and was impressed by the original street cab racing theme and dynamic gameplay. Against a backdrop of neon lights and upbeat rhythms, reels with car symbols spin, but most of all we are waiting for coins and other special symbols that promise generous rewards. The maximum winnings are up to x5,000 on the bet, and the Hold & Win bonus game really keeps you in suspense.

How to Play Mad Cabs Hold & Win slot online

The Mad Cabs Hold & Win slot machine has 5 reels in 3 rows and 10 fixed paylines. Winning combinations are formed from left to right on neighboring reels starting from the leftmost and consist of 3 or more identical symbols. The maximum multiplier to the bet of x20 gives 2 symbols - Wild and Pink Car, but only if they fall out in the amount of 5 pieces. The game uses:

  • expanding Walking Wild;
  • Collection feature;
  • Hold & Win bonus game;
  • Coin Shower feature;
  • Jackpots and special symbols.

Bets are allowed to be placed between €0.20 and €50. I think the simple rules make the game accessible to a wide range of users.

Mad Cabs Hold & Win Symbols, Wild, Scatter

The Wild symbol can substitute for any non-special symbol. It is a high-paying symbol. In the base game it can randomly turn into a Walking Wild - gaining the ability to move to the left, turning all symbols in the row into Wild. If the Walking Wild expands into a regular Wild, it increases its multiplier. If a Special Bonus Symbol gets in the way of a Walking Wild, the Walking Wild takes its value and adds it to the spin win total. I liked such wide powers of the wild, they significantly increase the size of the reward in the main game.

Special Bonus Symbol - Gold Coin. It has a certain monetary value in the range from x0.5 to x3 in increments of +0.5, from x3 to x10 in increments of +1 (counted by the bet). Appears in the main game, moves to a spot above the field, where it accumulates until a random moment when the Coin Shower feature starts. In the Hold & Win bonus game, it gives a win equal to its value.

There are several types of special symbols during the bonus:

  • Special Collector Symbol - green square with the inscription Collect, performs the features of a collector, i.e. collects the values of bonus symbols and displays the amount of winnings;
  • Special Mini Prize Symbol - gold coin with the word Mini in the center, promises a jackpot x25 to the bet;
  • Special Minor Prize Symbol - gold colored coin with the word Minor in the center, promises a x50 jackpot;
  • Special Major Prize Symbol - a gold colored coin with the word Major on it, guarantees a x250 payout to the bet.

In addition, in the course of the Hold & Win bonus feature, special symbols may appear on the field, indicating the multiplier that will be applied to subsequent symbols that fall into this cell. All of them have the same designation: Special (multiplier value) Multiplier Symbol, differing only in the size of the multiplier to the bet:

  • x2;
  • x3;
  • x4;
  • x5:
  • x10.

Blank Symbols also fall out during the bonus game. They have the form of a wheel and are used to mark the cells without winning.

Mad Cabs Hold & Win Bonus games

  • Coin Shower. Activated randomly. It manifests itself as falling on the playing field accumulated bonus symbols in the amount sufficient to start the game Hold & Win. A prerequisite - the presence of at least 1 special bonus symbol on the reels.
  • Hold & Win. To start the feature it is necessary that 6 or more special bonus symbols fall on the field. We get 3 respins, the appearance of each new special symbol resets the counter. During the game, only bonus symbols, symbols with multipliers and empty symbols fall out. All the symbols (except blank symbols and Special Collector Symbol) are fixed in their places. If you manage to fill all the cells with special symbols during the bonus round, a whopping Mega prize of x5,000 to the bet will be paid out. I like this feature - it gives you a real chance at prizes and keeps your attention until the last one.
