Novomatic/Greentube’s retro cabinet and dice-charged stepper thrills Description

Silver Lux Extra Dice drops you in front of a gleaming, old-school slot cabinet framed by the soft blur of a bustling gaming hall. The look is unmistakably classic: a compact grid and a crisp set of fruit-machine staples, with a twist that sits right above the reels—a Dice zone that springs to life when the core bonus kicks in. It’s a neat bridge between yesterday’s stepper charm and a modern layer of features that bursts like a firework when the right symbols click into place. Built by Greentube for Novomatic, this installment continues a broader Silver Lux lineage that plays with retro aesthetics while adding contemporary mechanics. Under the glass, the machine keeps everything immediate and readable: 3 reels, 3 rows, and 5 paylines that pay left to right. Stakes are equally straightforward, with a total bet ranging from €0.50 to €100 per spin, so you can spin at your pace. The backbone of this slot rests on a calibrated mix of classic paytable action and feature spikes: Extra Dice wilds with multipliers (x1, x2, x3, x5) that can combine up to x15, a Respin Feature that chases a third scatter, a Free Spins Dice Feature with progressive multipliers, and the headline attraction, the Silver Lux Linked Progressive Jackpot with two levels, Grand and Major. On the numbers side, the game is tuned for punchy swings: volatility is High, and the RTP is 93.70%, a figure influenced by the progressive jackpot contribution. It all comes together as a classic-first experience that doesn’t shy away from modern thrills—like seeing multipliers stack or the jackpot lights flash—while keeping the core rhythm of a traditional stepper intact.

Graphics and Symbols in a classic casino hall vibe with dice flair

Design and Atmosphere

The cabinet look is front and center: polished metal trims, glassy reel windows, and a blurred backdrop that suggests a lively casino floor without stealing the spotlight. Colors lean on bold reds and deep blues, with sevens and BARs glowing like neon icons. The aesthetic choice is deliberate: high-quality visuals framed in an intentionally generic, arcade-true presentation that lets the mechanical feel shine. The Dice area perched above the reels is the signature flourish—it lights up during the main bonus, reinforcing the “extra dice” promise right where you can’t miss it.

Sound Effects and Soundtrack

Audio follows the visual philosophy: classic, unobtrusive, and intentionally generic. It supports the cabinet feel without layering on cinematic cues, keeping attention on reel stops, symbol hits, and the moment those dice-driven features come alive.

Features and Bonuses with multipliers up to x15 and linked progressives

Extra Dice Wilds with multiplicative power up to x15

The wilds are the engine of the game. Extra Dice wilds can land as x1, x2, x3, or x5, and when two of them contribute to a line win, their values multiply each other for a combined boost up to x15. That alone gives even classic 3-of-a-kind hits a fresh spark. Land three wilds on a payline, and you unlock a special prize schedule that includes both fixed awards and jackpots: - 2x + 3x + 5x — Grand Jackpot - 2x + 3x + 1x — Major Jackpot - 2x + 1x + 5x — Major Jackpot - 1x + 3x + 5x — Major Jackpot - 1x + 1x + 5x — 75x the bet - 1x + 3x + 1x — 45x the bet - 2x + 1x + 1x — 30x the bet - 1x + 1x + 1x — 15x the bet It’s rare to see a 3x3 stepper lean this hard into wild logic, and the multiplicative twist makes simple lines feel delightfully volatile.

Silver Lux Linked Progressive Jackpot: Grand & Major

The jackpot layer comes in two flavors: Grand and Major. These are part of the Silver Lux Linked Progressive Jackpot, meaning the pots grow as play continues. Prize sizes can scale with stake, and the €100 maximum bet aligns with the upper range of the displayed jackpot values. When wilds land in the right 3-on-a-line configuration, the cabinet-style lights metaphorically flash, and those linked pots become the star of the show.

Respin Feature for a second chance at Free Spins

Two Dice scatters on the reels don’t just tease a miss; they lock in place and trigger the Respin Feature, spinning the remaining reel for a fresh shot at the third scatter. On a compact 3x3, that single extra roll feels tense and satisfying—like nudging a cabinet reel and hoping for the perfect click.

Dice Feature: Free Spins with progressive multipliers up to x5

Land 3 Dice scatters and you activate the Dice Feature (Free Spins). A dedicated Dice Reel above the grid determines the number of rounds—from 3 to 6 Free Spins. During the feature, all wins are multiplied by x2 to start, and that boost applies broadly—including all jackpots except the Grand and Major. Retriggers are possible: each time you refresh the bonus, the Dice Reel awards +1 to +6 Free Spins and steps the feature multiplier forward through x2 → x3 → x4 → x5. Once x5 is active, no further retriggers occur. It’s a clean, progressive ladder that balances brevity with spike potential.

Gamble Feature and quality-of-life controls

After certain wins, you can opt into a Gamble Feature for a double-or-nothing shot; it’s toggleable in the settings if you prefer to keep outcomes settled. For comfort, you also get Autoplay and sound controls. There’s no dedicated Turbo/Quickspin button, but you can stop the reels instantly with a double-tap on Spin, which feels satisfyingly cabinet-like in practice.

Statistics and Math for players who like the numbers

RTP

The game runs at an RTP of 93.70%, which is below the market average due to the contribution supporting the linked progressive jackpots. Practically, this means sessions can lean toward the long-game chase of features and jackpots rather than steady, small-cycle returns.

Volatility

Expect pronounced swings. The slot is tuned to High volatility, pairing a compact paytable with multiplier spikes, feature bursts, and jackpot shots. It’s ideal if you enjoy tension between quieter spins and powerful jolts when wilds or scatters align.

Paylines and Win Mechanics

The layout is intentionally simple: 3 reels, 3 rows, and 5 fixed paylines, all paying left to right. All regular wins require 3-of-a-kind, keeping reads instant and the rhythm unmistakably classic.

Bet Limits and Accessibility

Stakes are clear-cut and approachable: €0.50 minimum bet and €100 maximum bet per spin. Whether you prefer relaxed spins or a bolder profile, the range supports a wide variety of pacing.

Conclusion: classic stepper charm with modern jackpots and dice twists

Silver Lux Extra Dice nails the cabinet fantasy while adding just enough modern sauce to stay fresh. The standout is the Extra Dice wild system with x1/x2/x3/x5 values multiplying up to x15; on a 3x3 grid, that’s an exciting lever that can turn simple lines into highlight moments. The Respin Feature keeps the pace snappy when two scatters land, and the Dice Feature Free Spins offers a neat progression with its x2 → x5 ladder and quick-hit round counts. Add the Grand and Major linked progressives, and you’ve got a classic machine that can still light up a room. On the flip side, the RTP of 93.70% is below average, and the High volatility means you’re signing up for pronounced peaks and valleys. The audiovisuals are intentionally generic—on theme for a retro cabinet—but they won’t dazzle those seeking lavish presentation. For players who love stepper slots with meaningful modern twists, though, this is right on the money. If this flavor hits, consider these kin: - Wheel of Fortune Diamond Spins 2x Wilds (IGT) — retro styling, a progressive jackpot accessible via a wheel bonus, and multiplier wilds for classic-meets-modern moments. - Multi6Bells (Stakelogic) — adjacent “pay anywhere” feel with bonus symbols, a Multiplier feature, and a progressive prize; a different layout but a similarly punchy feature spine. - 40 Super Roll (EGT Digital) — 40 lines, a Gamble Feature, and 4 progressive jackpots, skewing toward quick-hit play with a broader reel canvas. For a compact, vintage-styled slot that can still surprise with multiplier fireworks and jackpot drama, Silver Lux Extra Dice is an easy recommendation—especially in demo mode, where you can throw the dice on every feature with pure, carefree curiosity.
