What we think about Diamond Mine Megaways slot

A faithful recreation of Bonanza Megaways, with all the magic of the original bonus features

Is Diamond Mine Megaways the right slot for you?

Megaways slots are some of the most popular games at PlayOJO online casino. They're bursting with special features, and Diamond Mine Megaways is no different. You can expect up to 117,649 ways to win, as well as free spins, a progressive win multiplier and a big max win worth up to 10,000x your stake.

This is Blueprint Gaming's first ever Megaways game, and they've created a tribute to Bonanza, the original Megaways game that started it all. When I first loaded up the game, I was struck by the similarities between the two. However, you can expect improved graphics and animations in Diamond Mine Megaways.

When you play Megaways slots, it's important to remember that the number of rows changes with every spin. Also, there's a horizontal reel above the rest of the reels. If it sounds confusing, don't worry; you can play the Diamond Mine Megaways demo to test it out for yourself. When playing for real money, always follow responsible gaming guidelines.

Game features

Megaways reels

The Megaways reels are unique because they change every single time you spin. There are six vertical reels, each with between two and seven symbols. With each spin, the number of symbols on the screen and the number of ways to win change.

Cascade wins

You land wins in Diamond Mine Megaways by matching symbols across adjacent reels from left to right. Every time you win, the winning symbols explode and are removed from the reels. New ones fall down to take their place in an exciting cascade, potentially leading to new wins.


Wilds in Diamond Mine Megaways only appear on the horizontal reel. As in other Megaways slots, they'll substitute for paying symbols, creating winning lines if you're lucky.

Mystery symbol

The TNT symbol appears anywhere across the reels, exploding to reveal a mystery symbol. Will it be one of the low-ranked symbols or perhaps a high-paying diamond? Whatever happens, there's a good chance it could land you a big win. The only symbol it can't reveal is the scatters.

Free spins

In Diamond Mine Megaways, scatters are big sacks filled to the brim with gold coins. Landing four or more anywhere on the reels will trigger the exciting free spins bonus. You get 12 free spins as standard, but an additional 12 are all yours for each additional scatter you land.

During the free spins, the winning potential is cranked all the way up, thanks to a progressive multiplier. This starts at 1x, and increases by one for each new win. Your multiplier will be in effect until the end of the bonus round, making it very exciting to play.

While the free spins may not trigger very often, it sure packs a punch when it hits. I had a lot of fun with it when I played Diamond Mine Megaways for this review. On top of that, it's possible to unlock more free spins during the bonus, with three scatters giving you five extra and four giving you ten.

Big Time Gaming really knocked it out of the park when they released Bonanza back in 2016. It kick-started the Megaways craze and has led to countless successful games based on it. Diamond Mine Megaways may be the updated version, but it's still worth checking out the original if you haven't already.

PlayOJO Megaways

That's right, it's our very own, totally exclusive game that you can only play here at PlayOJO. This slot, developed by IronDog, features a crazy number of ways to win as well as an exciting bonus round, where the number of rows is maxed out, and there's a progressive win multiplier.

My verdict

Bonanza is one of my favourite online slot games, and it's loved by players all over the world. The unique features may have become more commonplace thanks to the Megaways format taking off, but it's still a lot of fun to play. One downside of the original game is the slightly outdated graphics.

Blueprint Gaming has taken the classic formula and given it a brand new look, creating a game that's even better than the original. I had a lot of fun spinning the reels and watching for cascade wins and a free spins round that features a multiplier which keeps climbing higher and higher.
