1 People Voted!

4K Ultra Gold Slot is a 4ThePlayer slot launched in 2024. The game houses 6 reels and 4,096 paylines with a 94% RTP. This non-progressive slot game also features mobile, scatter symbols, wilds, bonus games, free spins. This game has a jackpot of 12,000x and is available for playing on both desktop & mobile.



Combining retro graphics and modern online slot features, 4K Ultra Gold by 4ThePlayer offers more than meets the eye. It attempts to stand out by bundling several popular types of slot bonus rounds into one big whole. Collector symbols stand side-by-side free spins and similar elements, which makes for an interesting new release.

It’s a good thing that 4ThePlayer worked hard on making the game stand out mechanically because it certainly doesn’t visually. It’s not bad-looking, mind you, it’s just that the 4k Ultra Gold slot game looks about as cookie-cutter as an online slot machine can be. It’s a vague Vegas-like theme with bright colours and even brighter lights. It may even be too bright for some players, but that’s beside the point.

Our 4k Ultra Gold slot review takes a detailed look into the game, how it works, and whether it’s worth your time and money.

The base game is exceedinly simple. 4K Ultra Gold is played on a large grid with 6 reels and 4 rows. The goal is to arrange matching symbols on 3 ore more consecutive reels, starting from the leftmost reel. The game doesn’t not have fixed paylines, which means that the row the symbols appear on doesn’t really matter. As long as you get 3 matching symbols on at least 3 adjacent reels, you win.

Some high-value symbols can win even with only two icons in a line.

Cash Symbols & Cash Collect

By far the most noticable feature in this 4ThePlayer slot are the Cash Collect symbols. They appear in both the base game and the bonus rounds and have multiple uses.

For starters, every star-shaped Cash symbol acts as a regular symbol with randomized value. This means you can collect them as you would regular symbols – by hitting winning lines. However, each symbol spawns with a randomi value. Any winning combination of Cash symbols simply sums up all of the winning symbols’ values and pays them out instantly.

Note that Cash symbols tend to be bigger on the rightmost reels. For example, Cash symbols on the first reel range from 0.6x to 2x, while those appearing on reel 3 can show 1-6x. Cash symbols on the rightmost reel appear as 10-20x, with a 100x maximum.

Additionally, these symbols can interact with a Cash Collect feature. Essentially, if the magnet-shaped Collector symbol hits anywhere on the grid, it instantly “collects” and pays out any Cash symbols currently on the board.

4K Ultra Gold Bonus Round

To activate the bonus round, land 3 or more Scatter symbols anywhere on the board. IF you do, you’ll be presented with a choice of the type of bonus round you wish to play.

Collect Spins

The first type of 4K Ultra Gold bonus round is called Collect spins. Hitting 3, 4, 5, or 6 Scatters grants you 2, 3, 5, or 10 Collect Spins, respectively.

These free-respins essentially remove all symbols from the game excelpt for Cash Collect symbols. You spin your spins and hope to collect as many of them as possible.

Also, a Collector symbols is guaranteed to hit with every spin. However, the other symbols from the game are still there – meaning the majority of reel positions are essentially blank spaces.

4k Ultra Gold Free Spins

The other type of bonus round is a more straightforward free spin round. You simply get 8, 12, 20, or 40 spins for 3, 4, 5, or 6 Scatters, respectively.

Additionally, Wild symbols during free spins will appear with multipliers between 2x and 5x. These will increase the payout of any winning line they’re a part of.

Feature Buy

If you’re not inclined to wait around for the bonus rounds to hit naturally, you can force them via the Feature Buy option.

  • 3 or more Scatters cost 50x
  • 4 or more Scatters cost 75x
  • 5 or more Scatters cost 125x
  • 6 Scatters cost 250x

After purchasing, you can pick between Collect Spins and regular Free Spins as usual.


There are 10 regular symbols in the game with varying values. Card ranks ranging from 10 to Ace are low-paying, and they’re mostly the same in terms of value with only minor differences. Casino chips and bells act as medium pays, with rewards ranging from 0.40x and 2.5x. The three high-paying symbols can also pay with only 2 symbols in a line, though the rewards are typically quite small.

The 4K Ultra Gold casino game also features quasi-progressive jackpots. Basically, hitting 3 Jackpot symbols of the same type anywhere on the table wins you the Jackpot. However, if you hit fewer than 3, each instance of a non-winning Jackpot symbol increases the corresponding pot by a small amount. However, each pot also has a hard maximum.

  • The Big jackpot starts at 50x and can grow to 300x
  • The Super jackpot starts at 100x and can grow to 750x
  • The Mega jackpot starts at 500x and can grow to 2,500x
  • The Ultra jackpot starts at 4,000x and can grow to 10,000x

4K Ultra Gold slot has an average Return to Player (RTP) rate of 94%. That’s well below the industry average and is one of the game’s biggest weaknesses. On the bright side, it doesn’t account for the increasing jackpots – the RTP value is as-is once you launch the game for the first time. It increases as you increase the jackpots, but not by much.

what we like

  • Cash Collector symbols
  • Choice between Free Spins + Collect spins
  • Quasi-progressive jackpot

what we don’t like

  • Low RTP
  • Low base payouts


The 4K Ultra Slot game from 4ThePlayer presents itself as a mishmash of different features we’ve seen in other games. The upside is that you can take your pick of the litter and enjoy the features you like the most. The downside is that none of them are particularly unique or fleshed-out.

Ultimately, the game’s RTP is its downfall. Considering just how much competition is out there in the world of online slots, recommending a game with 94% RTP is a hard sell. Its supposedly offset by the progressive jackpots. However, the pots don’t really make a big impact on most of the gameplay. You won’t see them often, and you won’t feel any better about the RTP.
