Slot Design

4 Diamond Blues Megaways online slot has a highly unusual gameboard, consisting of 6 reels, 2 to 7 rows and up to 117,649 Megaways™.

Because the symbols take a different amount of rows, the rows can range anywhere from just 2 to 7 on the same spin.

As you can see in the picture above, reel 2 has 6 rows, reel 3 has 6 rows as well, but reel 4 has 7 rows, while reel 6 has 4 rows.

There’s a bonus reel on the top that adds additional symbols to reels, 2,3,4 and 5.

This is thanks to the Megaways™ feature that offers up to 117,649 payways on a single spin.

The game has an RTP of 96.40% and variance set to HIGH, but the buy free spins feature which offers at least 12 free spins for a 100x price gets the RTP up to 96.48% which isn’t a big deal.

The minimum bet per spin is 0.10$ and the maximum spin is 20.00$, making this slot perfect for those players looking for a low wagering slot.

In terms of design the game looks great, the sounds and music are very well picked, resembling a diner of some sort as you can hear people talking in the background.

During gameplay the game often advertises the maximum win of up to 18,500x the bet.

In addition, the game shows that the average prize during free spins is 92x, but the cost to buy the feature is 100x, so it’s up to the player whether they want to risk it.

Slot Features

  • Megaways™: The payways in this online slot vary from spin to spin and can be seen on the top left of the screen.

As you can see from the screen, there are 15,120 paylines in this spin, but this number always changes. The maximum number is 117,649. Wins occur with symbols appears on adjourning reels.

  • Rolling Reels™: This feature triggers after every win on the board, replacing the symbols and adding new ones for a chance for consecutive wins. During free spins each consecutive win adds a x1 multiplier for each win. The multiplier remains through the whole feature and it’s unlimited.

  • Free Spins: Landing 4 scatters, which is the Diamond symbol, awards the player 12 free spins. If the triggering scatters are 5, the free spins are 17 and if the triggering scatters are 6, the number of free spins is 22. During the feature landing 3 additional scatters adds 5 extra spins and landing 4 additional scatters adds 10 additional spins. The game advertises that the average pay during free spins is 92x.

During our testing we did not reach these values, and most of the winnings we achieves were in-between 35x and 77x. We triggered the free spins 9 times in close to a 1000 spins.

  • Buy Feature: This feature costs 100x of the current bet, and guarantees you a spin with 4 scatters and 12 free spins. Any additional scatter adds 5 free spins on top of the 12. We bought this feature 8 times at max bet and did not make up our credits but once.

The winnings came to around 154x, but did not make up for the total amount of credits spent and won from the 8 features bought. Clearly this is a hit or miss, so proceed with caution. In some countries this feature is not available.


4 Diamond Blues Megaways is one of the best slots we have tested in terms of visual presentation.

The game has Rolling Reels™, Free Spins with unlimited multipliers and Megaways™ with up to 117,649 paylines.

On top of everything, the maximum winnings achievable are18,500x the bet or 370,000$ at max bet of 20.00$

Definitely on our recommended list, as this online slot gave us fun times and it was quite entertaining.

Perhaps it was the unusual gameboard, or the classic theme or just the overall vibe and music.
