Designed and developed by Buck Stakes Entertainment, 4 Diamond Blues Megaways is one more Megaways release to join the ever-growing Microgaming platform. Complete with scatters, wilds and other lucky symbols, this 6-reel and 117,649 ways to win game has a vintage look, but there’s nothing retro about its lucrative win potential. Just like the classic fruit theme doesn’t do justice to its skyscraping volatility. Be sure to read our full slot review before you play it, everything else that makes this game a money-spinner is noted further down this page.

4 Diamond Blues Megaways Bonus Features

As you’ll soon discover, 4 Diamond Blues Megaways is an old school kind of slot with one bonus round followed by wilds and scatters. The two other highlights in this slot include the popular rolling reels system and the persisting multiplier that only halts when you stop landing wins during free spins.

Buy bonus feature is also available for non-UK players and guarantees at least 12 free spins at the cost of 100x your stake.

Rolling Reels

The rolling reels mechanism is an integral part of the slot’s Megaways system, and the one that can generate big wins if you can match symbols on adjacent reels. Each time you form a successful payline, the winning symbols vanish from the grid, allowing new ones to fall into empty gaps and repeat the process. If it’s your lucky day, you’ll experience a train of wins on just a single spin.


You have one wild symbol included in the game’s upper bonus reel to help with winning combinations. If there’s a chance that a winning payline can be complete, the wild logo appearing as a casino chip will step in and substitute for all other paying symbols except scatters to achieve the win.


Scatters are your true friends in 4 Diamond Blues Megaways. Collecting 4 or more of them on the reels on the same spin will lead you into the free spins round, and every additional scatter landed on that same spin will boost your spin counter further.

Free Spins

You need at least 4 scatters to activate the bonus round with a minimum of 12 free spins and a persistent multiplier. Land more than 4, and for every extra scatter landed, you’ll top up your play balance with an additional 5 spins. The multiplier starts at 1x and amplifies with each win.

In this bonus round, scatters only appear on the top bonus reels and can award more free spins, from 5 to 10, if you happen to land 3 or 4 scatters respectively.

4 Diamond Blues Megaways Jackpot

Forget about the jackpots, the 4 Diamond Blues Megaways slot is offering a juicy win potential of 18,500x your stake instead.

RTP and Volatility

The development team at Buck Stakes Entertainment rated the game as a high volatility slot, and we wouldn’t have it any other way. Who doesn’t like to win big, even if only once in a while. The high RTP of 96.40% is credible but it’s also variable, so be sure to check this figure before playing.
