Page updated July 2026
Diamond Empire is a classic-style slot released under the Microgaming umbrella, built around an Art Nouveau aesthetic and a relaxed, understated soundtrack. It keeps things simple on the surface — a 3-reel, 3-row grid with 15 paylines — but hides some genuinely serious potential behind that minimalist exterior.
Diamond Empire goes for a classy, old-world elegance rather than the flashier visual style common in many modern releases, and that restraint carries through to the paytable too. Five regular symbols — single bars, double bars, triple bars, cherries, and sevens — make up the bulk of combinations, with sevens the most valuable of the standard set. The real interest lies in the diamond symbol, which acts as both a multiplier and a wild, substituting for everything except the scatter. Landing diamonds alongside regular symbols multiplies the win: two regular symbols plus one diamond doubles the payout, while one regular symbol plus two diamonds quadruples it. A full line of diamonds pays out at a substantial rate in its own right, and because that combination can theoretically repeat across all 15 paylines simultaneously, Diamond Empire's true ceiling reaches an eye-catching 10,000 times the stake.
Diamond Empire returns 96.04% to players over the long run, a solid, slightly-above-average figure that puts it on fair footing compared with the wider slot market.
This is rated a high-volatility slot, and the diamond multiplier mechanic explains why: most spins will land fairly modest combinations of bars and cherries, while the real upside is concentrated in the rarer moments when diamonds stack up across several paylines at once. There's also a bonus wheel, triggered by landing three scatter symbols, which awards a single spin with multiplier prizes up to 888x — adding a second route to a big result outside the base game entirely.
That 10,000x ceiling is genuinely rare for a slot built on such a stripped-back 3x3 grid, and it's almost entirely a function of the diamond multiplier stacking across all 15 lines at once. Exact stake limits for Diamond Empire aren't published in our data, so it's worth checking the in-game betting panel directly to confirm the range available at your chosen stake level.
Diamond Empire is a lesson in not judging a slot by its simple exterior — behind the restrained Art Nouveau styling and stripped-back 3x3 grid sits one of the more surprising max win figures around, courtesy of a diamond symbol that multiplies rather than just substitutes. With a 96.04% RTP and high volatility, it's a strong option for players who enjoy classic slots with real teeth.
