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.

FAQs

1.

Progressive jackpots (Mini, Minor, Major, Grand) activate only on maximum bet spins via random triggers or bonus rounds like free spins/pick games. Landing specific bonus symbols unlocks pick features where gems reveal jackpot values, with daily/hourly bonuses boosting accumulation.​

2.

Three or more free spin symbols award bonus rounds with multipliers and retriggers, where wilds substitute across paylines for frequent medium wins. Auto-spin and VIP meters enhance session length, tying into the classic diamond mining theme with escalating rewards.​

3.

The 5-reel setup uses traditional paylines but adds progressive jackpots, free spins, and magic spins for entertainment value without real money cashouts. RNG ensures fair payouts while paytables detail symbol values from low cherries to high diamonds.
