Diamond Duke online slot game
Diamond Duke combines a polished presentation with high variance in a straightforward, mobile-optimised video slot. Reel combinations are only part of the appeal: the main aim is to activate both bonus wheels for a chance at multipliers reaching 100x your bet.
Theme and Storyline
Diamond Duke makes its concept apparent as soon as the video slot loads. It takes a classic slot theme and adds a small twist: instead of having the reels fill the whole display, the game presents a first-person view of the complete fruit machine.
Graphics, Sounds and Animations
Although Diamond Duke draws on retro fruit-machine design, its visual treatment is contemporary and clean. The slot uses well-crafted, colourful full high definition graphics and is suited to both mobile and desktop screens. Its audio keeps the traditional fruit machine sound effects.
Top Casinos to Play Diamond Duke:
Gameplay
Diamond Duke uses 3-reel and 5-payline gameplay, with the potential for decent payouts through its three bonus features. A winning combination must begin on the leftmost reel and show three matching symbols along an active payline towards the right.
The six regular symbols are Cherries, Grapes, Melons, Bells, Sevens and Diamonds. Diamonds carry the top symbol payout at 160x your total stake. Filling every reel position with one matching symbol awards a payout on every pay line and also grants a free spin on the Multiplier Wheel.
Use the Diamond Duke paytable to see the return for each available symbol combination. It also outlines how the three bonus features work.
Bonuses and Free Spins
All three bonus features begin when the ‘Wheel’ scatter symbols land on the reels.
Bonus Wheel: Two ‘Wheel’ scatter symbols anywhere in view award 4x your bet and 1 spin of the Bonus Wheel. Its possible outcomes include multipliers of 2x, 3x, 5x, 7x or 10x your total bet, as well as the ‘Pick & Click’ bonus feature.
Multiplier Wheel: Landing 3 ‘Wheel’ scatter symbols anywhere across the reels awards 8x your total bet, plus a free spin on both the Bonus Wheel and the Multiplier Wheel. A Multiplier Wheel result of 2x, 3x, 5x, 7x or 10x is added to the multiplier from the Bonus Wheel. In combination, the rewards can reach up to 100x your total bet.
Pick & Click: The Bonus Wheel can lead to the ‘Pick & Click’ feature, which presents random multipliers over a possible three stages. Choosing ‘Collect’ finishes the game, while ‘Upgrade’ advances you. Stage 1 offers bet multipliers between 2x and 7x; Stage 2 has multipliers between 3x and 15x your bet; and Stage 3 can provide between 5x and 100x your bet.
Bet Sizes, RTP and Variance
Stakes range from 0.05 to 100.00 per spin. The stated RTP is 96.23%, while variance is high; neither figure guarantees frequent or large payouts.
Conclusion
Diamond Duke is a measured classic video slot rather than one that pays out regularly, although its wins can be sizeable when they land. The central objective is to activate the bonus features, where the larger multiplier opportunities are concentrated.
