Introduction
Diamond Heist is a recent 2020 robbery-themed release from Core Gaming. It’s a 6x4 slot, giving it an edge over the typical slot format with its six reels and 4096 betways.
Players will find the balance, stake and win at the bottom of the screen, but the user controls are to either side of the reels. Bet adjustment is to the left, and the main spin, autospin and game options are to the right. At the top of the reels you’ll find five hanging pots - the ‘Must Go Pots’.
This game has regular symbols, Bonus symbols and Wilds. There are four diamond-themed base game symbols: a diamond necklace, ring and a pure diamond, plus the Diamond Heist symbol. There are also six lower-value playing card symbols from 9 through to A, and a Bonus symbol, the diamond bandit. The wild will substitute for any symbols bar the bonus to help create winning combinations, and they can appear on the all reels except the first.
Theme & Graphics
This slot takes on a robbery theme reminiscent of those bank robber and jewellery heist movies with action and suspense as you wait and wonder whether the balaclava-clad bandits will get away with their loot.
A jewellery vault provides the landscape for the game, with drawers to either side where the diamonds are stored and CCTV cameras overhead. Rays of light shine into the darkened room and draw attention to the large reels dominating the center stage. The aesthetics are good quality and help cultivate the essence of the theme, bringing players into the middle of the heist action.

Diamond Heist RTP & Volatility
This has a decent 96.1% RTP, which we’d consider average for such a themed slot. It’s of medium volatility, so players could expect some variation in terms of win sizes and frequency, but generally speaking there should be some medium-sized payouts at a somewhat consistent frequency - more regular than a highly volatile slot.
How to Play Diamond Heist
1. Ensure you’re familiar with the game rules and paytable.
2. To play, simply adjust your bet on the right-hand side of the reels using the +/- buttons.
3. Once you’re happy with the stake, hit the green spin button on the right.
4. Autoplay is also available for players to select a number of automatic spins.
Bet Sizes & Paytable Wins
Bets start from just 0.10 and go up to a maximum wager of 10.00 coins.
The Diamond Heist logo pays from combinations of two at 2.00 up to combinations of six for 50.00x the bet, followed by the diamond, necklace and ring. The card symbols pay for combinations of three to six, with the most valuable being the A at 0.20x for two up to 1.60x for six.
Diamond Heist Bonus Features
Mystery Safe Deposit Boxes
This slot adds a little suspense with random Mystery Safe Deposit Boxes can that land on the reels. When that happens, the box will open and it’ll show any symbol of the same kind from the game’s paytable and will guarantee a win being awarded.
Free Spins
Three, four or five and above Bonus symbols will trigger free spins, with 8, 10 and 12 freebies granted respectively. For this round, any cascade will result in the loot on the conveyor belt being moved closer towards Flash Freddie (the bandit). It’s also possible to find a mystery deposit box in this round for mystery cash, extra free spins or a multiplier increment. There’s also a gold mystery deposit box for extra free spins, a multiplier increment or random wilds, providing extra boosts to payout potential during the round.
Must Go Pots
These are the progressive jackpots with tiered values that are guaranteed to be won prior to reaching the specified values displayed. If the pots start flashing randomly, a touch keypad will be displayed for the player, where they’ll be asked to enter a four-digit code in an attempt to unlock the diamond vault. The code is random, and it’ll change for each attempt. Guess correctly and you’ll win one or more of the five progressive jackpots displayed. Guess incorrectly and the vault will remain locked.
Our Verdict
The quality aesthetics and almost comical Flash Freddie make this an entertaining slot to enjoy. We like the themed bonus elements, in particular the Cascading Reels during free spins and the progressive jackpots, giving players more chances to win and the anticipation of bigger prizes on offer. The varied bonus features add to its longevity, with a decent RTP and medium volatility to keep gameplay both interesting and hopefully rewarding for longer.
The low 0.10 starting wager is sure to appeal to the casual players and those keen to keep the risk level low. The maximum 10.00 coin wager isn’t as high as some slots, so the highest of high rollers are unlikely to find it as satisfying, but this bet can still result in some generous payouts.
There’s enough in this slot to set it apart from the crowd, from the six-reel and 40960-payline format to the novel bonus features. It’s a fun, easy-to-play kind of slot that still packs a reasonable punch where prizes are concerned.
Another glitzy gem of a game is the Da Vinci Diamonds free slot, an IGT offering with 20 fixed betways and five reels. This comes with tumbling reels, scatters, free spins and up to 5,000x your wager with five-of-a-kind symbol combinations.
