Gameplay and Payouts: Inside the Fu Double Luck Diamond Explosion Demo

The Fu Double Luck Diamond Explosion slot demo operates on a 5-reel, 3-row grid with 50 fixed paylines. This 5×3 setup is traditional, but the high number of paylines, combined with a very high Hit Frequency, makes the base game active. Wins are calculated from left to right, starting from the first reel.

What Do Standard Symbols Pay?

The paytable is split into high and low tiers. The high-paying symbols are thematic: the two smiling Children (Boy and Girl, which appear to be the top symbols from the reels), the Pink Drum, and the Scroll. Landing 5 of the Drum or Scroll symbols pays 3x the total bet (€6.00 on a €2.00 bet). The Gold Coins follow, paying 2x the bet for a line of 5.

The low-paying symbols are the standard card ranks: A, K, Q, and J. These require at least 3 on a payline and offer smaller, more frequent wins to maintain balance while you hunt for the main features.

What Are the Special Symbols?

This game's action is driven by three key symbols:

1. Wild Symbol: A fiery gold icon. It substitutes for all regular paying symbols to help complete lines. Its primary role, however, is to randomly trigger the Jackpot Pick Deluxe feature.
2. Prize Symbol: A blue Diamond. This symbol carries cash values or jackpot names. It is the key to the other bonus feature.
3. Prize+Wild Symbol: A blue Diamond labeled “Diamonds Explosion”. This special symbol acts as both a Prize symbol (counting towards the trigger) and a Wild symbol (substituting for payline wins) simultaneously.

The Legend of the Lucky Symbols

The Asian-themed symbols in this game aren't just for show; they tap into deep cultural traditions of fortune, making this a classic Gold slot in spirit.

Symbol	Its Meaning in Culture
Fu Characters (on background)	The “Fu” (福) character is one of the most popular in China, directly translating to “fortune,” “good luck,” or “blessing.”
Gold Coins (Sycee)	These boat-shaped gold ingots were used as currency in imperial China. They are a powerful symbol of wealth and prosperity.
Pink Drum	Drums are used in celebrations, festivals, and ceremonies to drive away bad spirits and summon good fortune.

How to Trigger the Explosion Free Games?

The Explosion Free Games feature is triggered by landing 6 or more Prize or Prize+Wild symbols anywhere on the reels in a single spin.

This isn't a typical free spins round. It's a Hold & Spin (or Link & Win) style bonus. When triggered, all regular symbols fade away, and the triggering Prize symbols lock in place. The remaining empty positions become individual spinning reels. You are awarded a number of spins (typically 3-5, though not specified on the paytable) to land more Prize symbols. Landing a new symbol resets the spin counter.

How Does the Combining Block Mechanic Work?

Here is the unique twist: when Prize symbols land adjacent to each other (horizontally or vertically), they merge into larger blocks. A 1×1 block (a single symbol) pays a prize starting at 2x the total bet.

As they combine, the blocks grow, and their potential payouts increase significantly:

• 2×2 Block: Pays 6x to 20x total bet, or the Mini/Minor Jackpot.
• 3×3 Block: Pays 20x to 45x total bet, or the Mini/Minor/Major Jackpot.
• 5×3 Block (Full Screen): Pays 40x to 80x total bet, or the Minor, Major, or Grand Jackpot.

Each Prize symbol can only be part of one shape. The feature ends when you run out of spins or fill all 15 positions.

What Jackpots Can Be Won in Free Games?

During the Explosion Free Games, you can win the four fixed jackpots by forming large enough blocks. The Mini Jackpot (10x bet), Minor Jackpot (15x bet), and Major Jackpot (50x bet) can be won from various block sizes. The Grand Jackpot (a hefty 800x the total bet) is awarded by forming the largest blocks, including the 5×3 full screen.

What is the Jackpot Pick Deluxe Feature?

This is the game's second, completely separate bonus round. The Jackpot Pick Deluxe feature is randomly triggered whenever a Wild symbol lands on the reels.

When activated, you are taken to a new screen. You must pick from a grid of icons to reveal jackpot names: Mini, Minor, Major, or Grand. The first jackpot you match three of is the prize you win. This feature guarantees one of the four jackpots.

How Do the Jackpot Multipliers Work?

The most exciting part of the Jackpot Pick Deluxe feature is the potential for multipliers. With each pick before you secure your third match, a multiplier of x2, x3, x5, or x10 may also be revealed.

If a multiplier is revealed, it is applied to the jackpot you win. This means winning the Grand Jackpot (800x) could potentially be boosted to 8,000x (800x * x10), which aligns with the game's stated maximum win.

Vlad's Expert Tip: When you're playing the Fu Double Luck Diamond Explosion demo, pay close attention to the Wilds. The Jackpot Pick feature is not tied to the value of the line win. A single Wild on a non-winning spin can still trigger the 800x Grand Jackpot. This makes every Wild symbol that lands a high-potential event.

What is the Fu Double Luck Diamond Explosion RTP and Volatility?

The Fu Double Luck Diamond Explosion slot uses a mathematical model identical to other games in RubyPlay's “Diamond Explosion” series. The theoretical RTP is 96.82%.

This RTP is well above the 96% industry average, which is a strong positive. The volatility is rated Medium-High.

What Does the 8,000x Max Win Mean?

A 96.82% RTP with Medium-High volatility means the game is designed for exciting swings. You can expect periods of smaller wins, punctuated by significant payouts from one of the two bonus features. The Hit Frequency is a remarkably high 48.24%, meaning nearly 1 in 2 spins should result in some kind of win, keeping the base game engaging.

The game's Max Win potential is capped at 8,000x the bet. This is most realistically achieved through the Jackpot Pick Deluxe feature, by combining the 800x Grand Jackpot with the maximum x10 multiplier.

Hidden Synergy: Prize+Wilds and the Jackpot Pick

Let's talk about the Prize+Wild symbol. Most players will see it as a convenient 2-in-1 symbol, which it is. But its true power is subtle. Because it also counts as a Wild, it contributes to the random trigger chance for the Jackpot Pick Deluxe.

Here's the synergy: while you are trying to collect 6+ Prize symbols to trigger the “Hold & Spin” bonus, you are also increasing your chances of randomly triggering the other jackpot bonus. This dual-function symbol is the bridge that connects the two separate feature paths. I’ve noticed in the demo that spins with 3 or 4 Prize+Wilds feel electric, as you know you are close to one bonus (Explosion) while actively rolling the dice for the other (Jackpot Pick).

The Counter-Argument: Is the 800x Grand Jackpot Too Low?

So, here's a thought. Seeing “Grand Jackpot” and “800x” in the same sentence can feel… anticlimactic. Many modern Money-themed slots offer “Grand” prizes of 2,000x, 5,000x, or even 10,000x. Why is this one 800x?

The argument against it is clear: the top named prize feels achievable, but not life-changing. It’s on par with a great line hit in other games.

However, this critique misses the point of the game's design. The 800x Grand Jackpot is not the max win. It's the top prize in a feature that can be multiplied by 10x. The real Grand Prize is 8,000x. RubyPlay has simply shifted the excitement from winning the jackpot to the multiplier reveal within the pick bonus. The 800x prize in the Explosion Free Games is the “base” Grand, while the 8,000x version is the “Deluxe” Grand.

How Does the Buy Feature Work in the Demo?

The Fu Double Luck Diamond Explosion slot demo includes a Buy Feature option, allowing you to bypass the base game and trigger the Explosion Free Games immediately.

This feature costs 100x your total bet. For example, at the default €2.00 bet, the Buy Feature costs €200.00. Using this in the demo is an excellent way to understand the Combining Blocks mechanic without waiting for the 6-symbol trigger, which can take time.

Vlad's Expert Tip: Before you ever consider using a Buy Feature for real, you must test it in the demo. Use it 5-10 times. See how often that 100x cost returns 20x, and how often it returns 200x. This gives you a true feel for the feature's high volatility, which is often much more aggressive than the base game.

Uncovering the Secrets of Fu Double Luck

• The “Diamond Explosion” Engine: This isn't a one-off game. It runs on RubyPlay's “Diamond Explosion” engine. You can find the exact same math and features in “Diamond Explosion 7s” (a classic 7s-themed slot) and “Diamond Explosion Sweet Love” (a romance-themed slot). This game is the Asian-themed variant of this successful mechanic.
• The Hit Rate Illusion: A 48.24% hit rate sounds incredible. But remember, this includes all wins. Many of these will be micro-wins (less than your bet) from 3-of-a-kind J symbols. This high frequency is a “player retention” tool, designed to keep your balance steady while you hunt the two big bonuses.
• Dual Jackpot Access: The most unusual aspect is having two distinct bonus rounds that can both award the four jackpots. This is a rare design. Most slots, like the popular Mustang Gold from Pragmatic Play, have a Pick Bonus for jackpots and a separate Free Spins round for multipliers. This game makes everything about the jackpots.

Slots with Similar Mechanics to Fu Double Luck Diamond Explosion

If you enjoy the dual-bonus or “Hold & Spin” mechanics in the Fu Double Luck Diamond Explosion free play demo, you'll find similar experiences in these demo slots available on Respinix:

1. Mustang Gold (Pragmatic Play): This is a classic example of the genre. It features a “Money Collect” feature (similar to the Prize symbols) and a separate “Jackpot Reveal Bonus Game” (a pick-and-click bonus) triggered by a specific symbol combination.
2. Chests of Cai Shen 2 (Pragmatic Play): Another Asian-themed slot that features a random “Jackpot Bonus Game” triggered by Wilds, where you pick to match three “Fu” babies for one of four fixed jackpots.
3. King of Giza: Mega Cash Collect & Link (Playtech): This game is all about the “Hold & Spin” mechanic, but it uses the “Cash Collect” symbol to gather prizes, similar to how Fu Double Luck gathers prizes with its blocks.
4. Duo Fu Duo Cai Flower Riches (Light & Wonder): For a pure Asian jackpot slot feel, this game also features a pick-and-click jackpot bonus triggered by Wilds, fitting the Gold and Treasure themes.
5. Almighty Zeus Empire (Microgaming): This mythology-themed slot also uses a Wild-triggered pick bonus to award one of four fixed jackpots, mirroring the Jackpot Pick Deluxe feature.
6. Area Link Bank Boss (AreaVegas): A modern take on the Hold & Spin, the “Area Link” feature shows how sticky-symbol bonuses are evolving, much like RubyPlay's “Combining Blocks.”
7. Le Bandit (Hacksaw Gaming): For a different style of “symbol collect,” this Hacksaw slot uses “Golden Squares” and collect symbols, offering a high-volatility alternative.
8. YoDragon (PopOK Gaming): If the vibrant Asian theme is what you enjoy, this dragon-themed slot offers a different, but equally colorful, aesthetic.
9. Pirots 2 (Elk Studios): To see a complete contrast in game mechanics, try this ELK Studios release. It uses the “CollectR” mechanic, where birds hop around to collect symbols, showing a totally different approach to “prize collection” games.

Final Thoughts on the Fu Double Luck Diamond Explosion Game

So, what's the final verdict on the Fu Double Luck Diamond Explosion game?
It’s chaotic, in a good way. It’s not a simple, relaxing spinner. This is a game for players who want action. You are constantly on the lookout for two different triggers. The random Jackpot Pick from the Wild symbol provides a jolt of excitement that breaks up the base game, while the 6+ Prize symbol hunt builds a different, more sustained tension.

Honestly, this is a hallmark of RubyPlay design. They build slots that are feature-dense. The combining blocks in the Explosion Free Games are a fantastic visual and mechanical hook, turning a standard Hold & Spin into something more tactical.

Is it for everyone? No. If you prefer one massive, hard-to-hit bonus, this might feel fragmented. But if you enjoy demo slots where something is always about to happen, this is a perfect fit. The high hit rate and dual-feature paths make the Fu Double Luck Diamond Explosion slot demo an engaging experience. I'd recommend it, especially for testing the 100x Buy Feature to see the block mechanic in all its glory.
