Deco Diamonds (Microgaming) – Review & Demo Play

How to Play Deco Diamonds

I launch Deco Diamonds, set my bet with the Bet control, and keep all 9 paylines fixed. The paytable sits in the menu, so I check it first to see symbols, payouts, and feature rules. Stakes range from 0.10 to 50 credits per spin. I hit the large Spin button to run the 5x3 reels, or use Autoplay for 10, 25, 50, or 100 spins with Quickspin for faster rounds. Feature tabs above the reels pop up when a trigger lands, adding clear feedback.

Game Symbols in Deco Diamonds

The reels carry classic fruit machine icons with a Deco sheen. Cherries, plums, lemons, and watermelon form the lower tier, while bells, 7s, and diamonds are the premium set. The higher-value diamonds, 7s, and bells arrive as 3-symbol stacks, which helps land fuller lines when the grid lines up. This stacked behaviour matches the game’s land-based feel and pairs neatly with the respin mechanic when Deco Diamonds symbols show up across several reels.

The Deco Diamonds symbol is Wild and substitutes for all other icons. It also drives the features. Hitting 2, 3, or 4 Wilds awards a respin with those reels locked; new Deco Diamonds during the respin stick and grant another go. Land 3, 4, or 5 on the same spin and the Bonus Wheel launches as well. Five Wilds on a payline pays 1,000x your bet, which is the top line win on the paytable.

Deco Diamonds Paytable

Five-of-a-kind pays are straightforward. Deco Diamonds Wilds pay 1000x bet for five on a line. Among premiums, diamonds pay 100x, 7s pay 50x, and bells pay 25x. Among the fruit, watermelon pays 12.5x, lemons pay 10x, plums pay 7.5x, and cherries pay 5x for five. Diamonds and the Wild can also award wins from two of a kind on a payline, which helps pepper small hits between the more volatile feature-driven outcomes.

How to Win in Deco Diamonds

Wins form from left to right on any of the 9 fixed paylines. Most symbols need three or more matching on a line, while the diamond and the Deco Diamonds Wild can pay from two. Line wins apply the paytable multiplier to your total bet. The stacked premium symbols raise the chance of multi-line connections, and the Wild’s ability to substitute is central to completing those lines, especially when respins lock reels carrying Deco Diamonds symbols.

Bonus Features in Deco Diamonds

Respins trigger when 2, 3, or 4 Deco Diamonds symbols land. Those reels with Deco Diamonds lock while the others spin again. Any fresh Deco Diamonds that arrive become sticky and add another respin. The sequence ends when no new Deco Diamonds appear or the grid fills. Because reels holding Deco Diamonds stay fixed, it’s common to chain a couple of respins together and set up the Bonus Wheel trigger on the same sequence.

The three-level Bonus Wheel appears with 3, 4, or 5 Deco Diamonds. Silver offers 5x, 8x, 18x, 58x, and 80x. Gold offers 8x, 18x, 58x, 98x, and 588x. Diamond offers 18x, 58x, 98x, 588x, and 1000x. Press Stop to end the spin and take the bet multiplier. Landing a level-up segment upgrades the wheel from Silver to Gold or Gold to Diamond, which is where the largest multipliers sit.

RTP (Payout) and Volatility – how it affects your game in Deco Diamonds

Deco Diamonds runs with an RTP of 96.03%, which sits just over the long-term average. The slot is high volatility, so in my sessions the base game can feel sparse before features hit. Betting is simple due to fixed paylines; I move stakes within the 0.10 to 50 credits range without juggling coin sizes or lines. Autoplay options suit set-and-forget play while you chase stacked symbol hits and Deco Diamonds triggers.

The top possible prize per spin is 2,323x your bet, achieved through the feature mix and the Bonus Wheel multipliers. There’s no free spins round, but the respins and wheel create swingy peaks when multiple Deco Diamonds cluster. In practice, I look to combine stacked premiums with Wild substitutions in the base, then rely on respins to pin those positions and give the wheel a shot at a larger multiplier.

The 200 Spins Deco Diamond Experience

I ran a 200-spin session at 1.00 credit per spin after checking the paytable. The first block of spins delivered only a couple of small fruit line wins, which tallied with the high volatility. On spin 22 I hit a respin but it fizzled. A bigger hit arrived on spin 31 at roughly 20x. The mechanical tabs above the reels helped signal feature moments cleanly without cluttering the screen.

On spin 62, three Deco Diamonds landed, which granted respins and launched the Bonus Wheel. The respins yielded 12.50, and the Silver wheel stopped on 8x, for a total of 24x on that sequence. Across the full 200 spins I saw eight respins, five Big Wins, and two Bonus Wheel entries. I didn’t reach the Diamond Wheel level, but the upgrade tiles keep the sweat going when the pointer flirts with them.

By the end, my balance ticked up to 2,043 credits from a 2,000 starting stack. The stacked symbols and Wild behaviour carry the base, while Deco Diamonds symbols are the heartbeat of the game. The mix of respins and the three-tier wheel gave me regular shots at mid-range payouts, with the top multipliers feeling rare but within reach when several Wilds lock across the reels.
