Interested in some new online slots? Well, you are in luck! Several industry leading online casinos have rolled out new and exciting slot games this month. Below is a list of some of our favorite recently released games for August, 2023

DraftKings

Black Diamond

Upon entering the Black Diamond online slot game, it shows a minimum bet of $2.25. The max bet stands at $6.75.

From Everi Digital, Black Diamond is a traditional 3x3 slot game. It offers nine paylines.

Payouts start at 9 for any three Bars. They go up to 15,000 for three Black Diamonds (at less than max bet).

Progressive jackpots come from max bets.

A Minor jackpot pays up to $499.99 for three Black Diamonds on paylines 1-8 with a max bet. The Major jackpot pays up to $49,999.99 with three Black Diamonds on payline 9 with a max bet.

The Black Diamond symbol also serves as the game's wild — except for multipliers.

You'll get 2X multipliers from two or more 7s and Bars on a payline. A single bar or 7 offers 3X multipliers. The 77, 777, and Double Bar symbols offer 5X multipliers.

The multipliers max out at 30X.

Black Diamond serves as a perfect option for beginners with a sizeable bankroll.

Try the demo version first before getting started.

Reign of the Mountain King

Another new online slot at DraftKings is Reign of the Mountain King. This version is a follow-up from SG Digital's Rise of the Mountain King.

There's a minimum bet of $0.10 and a max bet of $10. So, this might be a better choice for those with a smaller bankroll.

The game has five reels, three rows, and 10 paylines. You'll need to get three or more matching symbols, starting from the left, to win.

9, 10, J, Q, K, and A offer payouts from $0.50 to $5.00.

A shield, ax, and three character symbols payout from $2.00 to $20.00.

As with most online slots, the game pays out for the highest winning combination. Wins on separate paylines get added together, as well.

The Mountain King symbol also serves as the game's wild. Any three wild symbols that appear on reels 2, 3, and 4 triggers a Respins Bonus.

Multipliers come from ONE wild in any four or five of a kind. Other wild multipliers may apply to a three-of-a-kind. They start at x5 and go to x8, x64, and x512.

A bonus round offers chances at multipliers with wild symbols on reels 2, 3, and 4.

In the base game, you may also collect up to three GEM symbols. They come with multipliers of x2, x3, x5, and x8.

The return to player (RTP) value of Reign of the Mountain King stands at 96%.

Diamond Fruits Megaclusters

From Big Time Gaming, Diamond Fruits Megaclusters is one of the more unique new online slots.

The game offers five reels, five rows, and an RTP of 96.23%.

There are six 3D fruit symbols, plus a diamond. Five or more matching symbols that appear horizontally or vertically generate payouts. The symbols may be large or come within smaller megaclusters.

A minimum bet starts at $0.20 and a max bet tops out at $60, making this a decent option for any bankroll.

The symbols come from the foreground on each spin, paired with electronic dance music. Winning clusters also "react" and new symbols take their place, giving you more chances.

Thus, a winning symbol gets replaced by four smaller ones. This process repeats until there are no more winning combos.

The wild substitutes for all symbols. Three or more "reactions" trigger a Wild Canon Bonus, adding anywhere from five to 15 wilds.

Eight reactions trigger eight Free Spins. (Any extra reactions might trigger more free spins, too.)

Win multipliers begin at one and may increase with every reaction.

So, this is a great game if you catch a hot streak.
