Mega Cubes Deluxe: the Fazi dice slot with a random progressive jackpot

Developed by Fazi, Mega Cubes Deluxe is a dice-themed slot running on 5 reels and 3 rows, with 5 fixed paylines, a certified RTP of 95.48% and high volatility. The game features a randomly triggered progressive jackpot, a star scatter symbol and a colour gamble function that lets you double every win. Total bets range from €1.00 to €50.00, with a demo mode available without registration and full compatibility across mobile and desktop.

Dice on a dark background — and a jackpot with no maximum bet requirement

The paytable is built entirely around the six faces of a die, from low-value symbols (1 and 2) through to premium symbols (5 and 6), alongside a golden star scatter that pays out regardless of its position on the reels — no alignment needed. Visually, the cubes roll across a dark background with a purple glow running through it, a restrained aesthetic that makes this title instantly recognisable within the wider range of online casino slot games. Sound design is calibrated for extended play sessions without becoming fatiguing — an ergonomic detail that runs consistently through Fazi's catalogue.

The progressive jackpot is the game's defining feature. Unlike traditional jackpots that require a maximum bet or a specific symbol combination, this one triggers completely at random, at any stake level. A player betting €1.00 per spin is just as eligible as one playing at €50.00. The jackpot value is displayed in real time and increases with every spin played across the entire Fazi network, giving it a visible and continuous build between sessions. This makes it one of the few dice slots where an exceptional payout is on the table without needing to change your usual stake.

The gamble feature: double or nothing on a 50/50 call

After every winning combination, the game presents a colour gamble option: pick red or black on a randomly drawn card. Get it right and your win is doubled; get it wrong and it disappears entirely. The feature is entirely optional — declining it has no effect on normal gameplay. You can chain multiple gambles on the same win, which compounds the potential upside but also the risk of total loss at each step.

It is the only active decision a player makes in this game. On a high-volatility slot where big wins are infrequent, how you use the gamble feature can meaningfully shift the outcome of a session. A run of correct guesses on a large win can turn an ordinary session into a memorable one; a single wrong call on a substantial win can undo what took many spins to build. Testing this mechanic in demo mode before using it with real money is the sensible approach — it helps you understand the rhythm and the practical impact on your balance.

95.48% RTP with high volatility: what this actually means per session

An RTP of 95.48% places this game at the upper end of the regulated Belgian iGaming market, where the dice slot average sits between 94% and 96%. In practical terms, over a large volume of spins, the game returns a statistical 95.48p for every €1 wagered. High volatility, however, changes the real-money experience considerably: wins arrive less frequently than on a medium-volatility slot, but when they do land, their size tends to be proportionally larger.

For a player working with a session budget of €20 to €50.00, this profile means stretches of spins with little visible return, punctuated by occasional wins that can offset several losing rounds at once. Stake sizing matters here — betting too high relative to your available balance risks burning through your budget before the larger wins that characterise high volatility have a chance to appear. The demo mode is designed precisely for this: finding the right stake-to-balance ratio before any real money is involved.

Desktop, mobile and autoplay: how to set up the game

On desktop, the total bet is adjusted using the + and - buttons in the main menu, between €1.00 and €50.00. Spins are launched with the dedicated button or the spacebar. Autoplay lets you set between 5 and 1,000 consecutive spins, with configurable stop conditions: jackpot trigger, win exceeding a defined threshold, or balance reaching a chosen limit.

On mobile, the touchscreen interface replicates all the same functionality, with button sizes suited to smaller screens for smooth navigation. Visual quality and animations are maintained across all screen formats. The mobile autoplay stop conditions are identical to those on desktop — a useful feature for sessions where you are not watching the screen continuously.

Playing on a licensed Belgian gambling site: what it actually guarantees

Playing at Loco Casino, one of the regulated gambling sites operating under an A+/B+ licence from the Belgian Gaming Commission, guarantees that the RTP displayed is the game's actual certified figure — not an estimate. A licensed platform in casino Belgium dice and slots regulation means strict obligations: verified game data, responsible gambling tools and prompt withdrawals depending on the payment method selected. None of these protections apply on unlicensed platforms operating outside the Belgian regulatory framework.
