Black Diamond 25 Lines Slots

Black-Diamond-25-LinesBlack Diamond 25 Lines is the fourth game from the series with this name, and it has a modern design, more paylines than any of the others, more symbols and more features. All in all, this is the one I’d go with if I were you, but that’s because I do enjoy a slot machine with more features. The theme has remained the same, based on various gemstones and precious metals, together with the mountains from where they’re supposed to be extracted from. The developer that created this series of slots is called Top Game.

The best looking and most modern version of Black Diamond is the 5 reel and 25 line version, the one we’re reviewing here. It has wild symbols inside, scatter symbols with free spins, and a bonus game as well. A $30,000 top jackpot is on the line, the same payout as in the other slots.

Features of Black Diamond 25 Lines

While the classic variants got you only a wild symbol, the 25 Lines version also has scatter symbols, free spins and bonus games to offer.


The wild symbol remained the same as before, a Black Diamond icon that is capable of substituting for other symbols. It can substitute for the regular icons, and only for them, so bonus and scatters don’t get any help from it. It also doesn’t offer any payouts of its own in this game, the role of the jackpot trigger being handed out to another symbol.

Free Games Feature

You have the scatter symbol on the 1st and the 5th reels only, and you need it on both of them at the same time, in order to get the 10 free spins activated. The scatter symbol is the Ruby, one of the two such gemstones to appear in Black Diamond.

Bonus Game

There is a bonus game as well here, which triggers when a set of Gold Bars appears on three reels simultaneously, and on an active payline. The reels that the Gold Bars have to be on are the three in the middle (2, 3 and 4). Payouts offered by it go from 40 to 200 coins, depending on how well you do in it.

Betting options and jackpots

It’s a much more expensive slot than the others, with a lot more paylines for players to use. Each of the 25 lines gets 1 coin, so 25 coins are used when all the lines are active. As for the individual coin value, it’s at $5 for the maximum, or $0.01 for the minimum. $125 is the maximum wager here.

Since the best combo of the game offers 6,000 coins, the total jackpot value is at $30,000.

Design and symbols

There is a lot more to see in the 25 Lines game than in the other three from the Black Diamond series. A lot of things were kept the same, like the design style, the silver metal influence, the mountain ranges in the background or some of the symbols (black diamond, ruby, purple gem). There are new symbols as well on the reels, more features and it’s an overall better looking game, since the paytable is no longer placed on the same screen as the spin area.

Symbols: Black Diamond (wild), Ruby Apple (scatter), Bonus Gold Bricks (bonus), Yellow Diamond (6,000 coins), Ruby (1,000 coins), Saphire (500 coins), Purple Gem (300 coins), Blue Gem (200 coins), Opal (150 coins), Diamond (125 coins) and Silver Ring (80 coins).

Is It Worth Playing?

It’s much more expensive than the other slots called Black Diamond, but it’s also the only one with a lot of features to offer. It offers the same prize as the classics though. I for one enjoyed it the most.
