My Experiences with the Slot

Having played White Diamond much more than this slot, the prequel to this game, I used my knowledge to evaluate Black Diamond. Here’s what I think about its features.

Bet Amount: High Risk, Bigger Rewards

When I was in a more relaxed mood, I used lower stakes with this slot machine. But the multiplier was only 1x. Sliding the lever to the max, I spent more but also received a 3x multiplier and a chance to pocket the jackpots. I discovered that the max bets also increased the frequency of wilds. White Diamond has the same feature.

What are the Best Features?

Overall, I think the 3x3 grid is the most favourable element. Allow me to explain. Nine paylines cover the whole grid. Coupled with medium volatility, this added up to regular triple-, quadruple-bet wins. I found this worth it while I was chasing the jackpots. Yes, I had a one in a million chance to land them, but the fun from walking the long walk was still there.

Alternatives to Black Diamond

Black Diamond is a classic online slot in the mould of Mega Joker, which is a decent alternative. It has fewer paylines (5) and offers no jackpot, but the RTP of 99% is amazing. If you can't compromise with the number of paylines, go for Jackpot Giant, a fruit slot with 50 winning ways and jackpots.
