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.

When choosing a site to play Iron Dog Studio slots, I always look at the "base". A reliable casino is:
Be sure to read the reviews of real visitors, it will help you make the right choice.
Start getting to know the new products through the free demo mode.
For 4 Wild Riches, this is especially important as the volatility of the slot is high and you need to get a feel for the frequency of the Hold & Win bonus. I played the demo for about three hours: the mechanics are clear, but it requires patience.
On Casinoz we offer only sites where 4 Wild Riches is running stable and without delays. At each casino on our list, you can play for money and collect your rewards in peace.
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:
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.
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):
Blank Symbols with gemstone outlines are used to fill in the unwinnable positions in the bonus game.
Super Diamond. Activated randomly, triggering the Hold & Win bonus game with all three effects at once.
Hold & Win. This is the main bonus of the slot and has 3 variants as it can be triggered by different special symbols:
On each of the reels can fall a gemstone of the same color, it is he who randomly activates the bonus game. In this case, all special symbols remain in their places and the process begins, consisting of 3 respins, the number of which is counted on the counter and resumes every time at least one new special symbol falls out. If you manage to fill all the cells of the playing field 5x3 special symbols, will be paid Grand Jackpot in the amount of x5 000 to the set bet. Similar luck in the game, activated by Ruby (with a field of 5x6), will bring double Grand Jackpot with an extravagant amount of x10 000 to the bet.
Instead of classic free spins, the slot machine emphasizes a multi-level Hold & Win bonus that offers free respins.
4 Wild Riches features fixed jackpots that can be hit during the bonus round. Their size is tied to the bet:

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.

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:
The center of the panel displays:
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.
The 4 Wild Riches mobile slot is perfectly optimized. The game loads in 15 seconds on my iPhone 13, and the control buttons are large enough not to miss. The iOS and Android versions are identical to the desktop version.
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!
The level of return to the player can be 91, 93 or 95%.
The slot has 5 reels in 3 rows and 20 fixed paylines. During the Extra Board bonus feature, the number of rows increases to 6.
Players can win a maximum of x10,000 to bet.
