Operation Diamond Hunt Mini-Max Overview

Operation Diamond Hunt Mini-Max is a spy-themed slot from Kalamba Games, launched on 11 May 2023 according to Kalamba’s own portfolio. It is the Mini-Max edition of the 2019 Operation Diamond Hunt: six reels in a 3-4-5-5-4-3 layout with 3,600 ways. Kalamba rates it 9/10 for volatility, lists a hit frequency of 39.3% and a maximum coinciding win of 25,000x. SlotCatalog gives an RTP of 94.08%.

Symbols and the Wild

The reels are set in a gilded palace hall. Card ranks from 9 to A in diamond lettering make up the low symbols; the high ones are luxury items – a diamond watch, a roulette wheel, a golden pistol, a sports car and a yacht. The secret agent is the Wild. In our screenshots three cars paid 14.00 at a bet of 50, and a larger combination with the Wild on reel 4 paid 210.00 – 4.2x.

HyperBet: Three Gold Symbols

The HyperBet panel on the left shows the pistol, the car and the yacht in gold. You raise it with the arrow buttons to turn up to three of these symbols gold; according to the game description, this raises the stake and the potential wins.

The Cashpot

The Cashpot on the right has three prizes that scale with the stake: at a bet of 2 they read Platinum 20,000, Gold 400 and Silver 40, and at 50 they read 500,000, 10,000 and 1,000 – 10,000x, 200x and 20x. According to a published player win report, 16 gold symbols triggered the Silver prize and 22 gold symbols the Platinum.

Big Win Replays

The Big Win Replay panel lists the game’s biggest recorded multipliers: x10459, x10038 and x2180. The x10038 entry matches a reported €20,000 Platinum win on a €2 bet.

Diamonds and Free Spins

The blue diamond marked BONUS is the symbol to watch – one of our screenshots shows it on reel 2. According to the game’s published description, diamonds collected in the bonus game award free spins, and the round chases Wild multipliers for bigger wins. The same description names the three Cashpot levels as individual bonus jackpots.

Buy Bonus

A Buy Bonus button sits under the reels. Kalamba calls this HyperBonus: it takes you straight into the free spins round. Kalamba also lists a gamble feature for this edition, which the 2019 original did not have.
