4ThePlayer has earned its place among the top slot sites due to its innovative slot mechanics and mobile-first approach, so let's see if 4K Ultra Gold is another game to add to the list of winning games? Join me as I give the game a test drive.

4K Ultra Gold is a medium-high volatility slot game, the RTP is 94%, and you play on a 6x4 grid.

A feature I'll tell you more about is the bonus round, where you get to choose Free Spins or Collect Spins. During Free Spins, Wilds turn into multiplier wilds to increase your wins. And if you select Collect Spins, a Collect Scatter lands on every spin to award every cash prize you see.

Sit tight as we start this in-depth 4K Ultra Gold slot game review.

100 Spins Test

This 100 Spins will be updated by Steve Madgwick 

100 spins is not a Real Test

We give every slot a 100 spin test to see just what it can do, or not as the case can often be - 100 spins is no reflection of the likelihood of any other 100-spin session, as RTP's are set over many millions and probably billions of spins. So this 100 spin test is just for entertainment and insight purposes

Game Data

Collected by Andrej Trajkovski


This electric and energetic slot game moves at a fast pace and has a retro, almost 80s feel to it. Expect plenty of vivid colours, sparkling gold and rapid movement while you play. 

In addition to the bonus round, the Money Ways Gold cash symbols are an exciting feature. They create 'ways wins' with cash prizes which grow bigger and bigger. You can even win all of the cash prizes in view with a Collect Scatter.

Right, let's dig deeper with this extensive slot game review.

Graphics, Music, and Sound Effects

Upon launching the game you're met with the roaring sounds of electric guitar riffs - you'll hear plenty of solos during this rock soundtrack which has a 1980s energy.

The creatives are retro and resemble classic slot machine themes. The sound effects reflect this, too, so expect an abundance of jingling coins and beeps.

Key Features

Written by Slots Content Manager Jenny Mason  

When we create our OLBG slot reviews, we follow up the summary, intro, graphics, music, and sound effects with the key game features. This info will help you decide if 4K Ultra Gold sounds like a yay or a nay.

We share many slot games reviews on OLBG and these include up-to-date info about essential features such as theme, paylines, reels, bet range, and bonuses. Don't go anywhere if you want to find out about our play experience, first impressions and our expert verdict of the 4K Ultra Gold slot game.

Theme - Retro

4K Ultra Gold has a retro feel, featuring primary colours, nostalgic fonts, and classic slot imagery. Gold is a prime focus of the game, which is no surprise, given the name. Gold is heavily featured in the symbols and features too. 

A gold colour borders the grid complete with golden stars to make it sparkle. The symbols from the highest value first are a gold dollar sign, a gold bullion, a golden horseshoe, a golden chip, and a golden bell. These are then followed by the standard symbols of A, K, Q, J and 10.


The 4K Ultra Gold slot game has 6 reels and 4 rows to play on. 


Landing winning combos is possible on 4,096 paylines for the 4K Ultra Gold slot game.


Return to Player, or RTP, as you've probably seen written on slot sites, is a way of forecasting what percentage of players' stakes will be returned to them over the long term. It's always represented by a percentage that is usually somewhere around 96%. The 4K Ultra Gold slot RTP is below average at 94%.

There are different RTP rates available, so you’ll need to check on operator sites to find out which RTP rate they're offering. To save you time, we’ve found a few different rates at some of the top UK online casinos and added these sites to the table below.

It's worth mentioning that RTP is just one consideration when deciding which site to play at. You should also look at payment options, amount of games, customer support and welcome bonuses and deals. Our casino reviews look at this info and much, much more.

If you fancy trying out more than one game you should visit this page with the slot sites we recommend.   

Stake Range

There’s a wide bet range for the 4K Ultra Gold slot game which starts at 20p and goes up to £80.

Max Win

The 4K Ultra Gold max win amount is 12,000x your stake

Wild Shape

The Wild symbol substitutes for all other symbols apart from the Scatter symbol. Wild symbols can appear on any reels 2-6. 

Free Spins

Landing 3 Scatter symbols triggers the bonus round, during which you can choose between Collect Spins and Free Spins. 

If you select the Free Spins bonus round, Wild symbols that land will transform into Multiplier Wilds, each with a random multiplier. The number of normal paying symbols on the reel is increased by the multiplier of a Wild on the same reel. Cash prizes are multiplied by the Wilds on the reels they are on. You can be awarded extra free spins if you land Bonus Scatters during this bonus round.

If you opt for the Collect Spins, only Gold symbols which have cash prize values, or Collect symbols land on the reels. There are no extra spins available for this round.

Play Experience & First Impressions

Having the choice of Free Spins or Collect Spins is a nice touch. The last 4ThePlayer game reviewed was 7 Gold Fruits where you have the choice of Free Spins or Respins. Hey, it’s always good to have options!

Here is a bit more information about the Money Ways Gold cash symbols that were mentioned in the Intro section. You create ways wins with cash prizes, and the prizes grow bigger and bigger (left to right). Their value goes all the way up to 100x the bet. You can also win all cash prizes in view with a Collect Scatter. The more Collect Scatters you land the more cash prizes can be won multiple times.

Boosting Fortunes is also a headliner feature where every Gold Cash symbol that lands on the reels is increased and they keep increasing until you win. If a Fortune symbol lands but doesn't win the Forrtue prize it is boosted for future spins.  There are 4 prizes up for grabs - the Ultra, Mega, Super, and Big Fortunes. These can land on the reels and are won along with cash prizes. 

Expert Verdict

4Theplayer is known for its innovative features and in the summary I asked if this game would be added to the list of winning games? From an originality point, I'm not so sure. The bonus round was fun and having two options to choose from added a fun element. However original headliner features were not obvious for this game. A recent title created here at OLBG was 4 Fantastic Fish Gigablox and that had the superb Gigablox mechanic with gigantic symbols appearing on the grid.

The retro style, design and music look a bit dated however this will appeal to some slot players. You can read more about 4ThePlayer slot games as I've compiled a full list of games including RTP, volatility and max win measures to help you find the right game for your needs. From this list, 4K Ultra Gold is the lowest RTP of all of the games so far. However, it's in the middle range for max win as at 12,000x it's the 13th highest max win out of the 29 games released so far.
