Expert opinion

The online slot 4 Wild Riches from Iron Dog Studio is a real treat for those who love gems and pure excitement. Unlike many of the studio's games, there is no overloaded plot: all the attention is focused on the 5 reels filled with bright crystals. The music is cheerful, modern, and each "skid" is accompanied by spectacular animation. The exciting Hold & Win bonus is presented in three variants, and the main reason why I hung out in the slot for a couple of hours is the solid winning potential of x10,000 to the bet.

How to Play 4 Wild Riches slot online

The 4 Wild Riches video slot uses a grid of 5 reels in 3 rows with 20 fixed paylines. In order for a win to be counted, 3 or more of the same symbols must appear on adjacent positions in the order determined by the pay table, starting from the leftmost reel. Two symbols are paid maximum if they fall out in the amount of 5 pieces (Wild and Diamond) - in this case a multiplier x50 is applied to the bet. Winnings for coins are taken into account after the payouts for lines. Features used in the game include:

  • Hold & Win;
  • unlocking additional rows;
  • additional spins;
  • additional payouts;
  • Super Diamond.

Rubies, Emeralds and Sapphires falling in the base game move to gems of the corresponding color above the reels and simultaneously replenish the stock and size of the diamond with the crown and Super inscription, which spontaneously triggers the Super Diamond feature. In my opinion, the game rules are simple, making the slot accessible to a wide range of gamers. You can bet on a spin from 0.10 to 2.40 euros.

4 Wild Riches Symbols, Wild, Scatter

The Wild symbol is a picture with the image of three gems and the corresponding inscription. It can substitute for any non-special symbols. It is a high-paying symbol. During the Hold & Win bonus game, special symbols become active ( depending on the bonus option):

  • Ruby, which is a Special Red Extra Board Gem and adds 3 rows to the playing field;
  • The Emerald, which is a Special Green Extra Spins Coin that gives +1 respin;
  • Sapphire (Special Blue Extra Pays Gem), which adds a random multiplier to the bet ranging from x2 to x10 in increments of +1 to at least 1 special symbol, excluding jackpot symbols;
  • Gold Coin, which has a cash value in the form of a multiplier to the bet of the following sizes - from x1 to x10 in +1 increments;
  • Several Special Jackpot Coins with jackpots of different sizes.

Blank Symbols with gemstone outlines are used to fill in the unwinnable positions in the bonus game.

Strategy: How to Win at 4 Wild Riches slot

I've noticed that the slot likes to "rock". That's why you should focus on a long session, quick "rush" rarely works here. Try not to bet a lot at once, start with the minimum.

And do not forget that no strategy will not help you win often and a lot. Only luck works here.

4 Wild Riches Interface

The interface of the 4 Wild Riches slot is simple and intuitive - I figured out the controls in a few minutes. The main controls are:

  1. Menu (opens the rules, payout table and settings).
  2. Sound (allows you to turn on and off music and effects). Bet (changes the size of the bet).
  3. Spin (starts one spin).
  4. Auto Play (automatic mode with selection of the number of spins).

The center of the panel displays:

  • current balance;
  • the selected bet;
  • the amount of the last win.

I tested the slot in manual and automatic modes - spins start without delays, bets change quickly, the interface is not overloaded with details and allows you to focus on the game.

Should You Play 4 Wild Riches Slot for Real Money?

4 Wild Riches is a solid high quality video slot for those who don't like unnecessary fuss with the plot, but come for the big wins. Unfortunately, the game does not quickly give access to its riches. So, to start the bonus, I had to spin the reels 250 times, and in the end the Extra Spins feature brought me only x18 to the bet. But don't forget that everyone's luck is different, so try and hope to win!
