Understanding the Diamonds Power XXL Gameplay

The Diamonds Power XXL game operates on a 5-reel, 4-row grid with 15 fixed paylines. This 5×4 setup is standard, and wins are formed by landing matching symbols in succession from the leftmost reel to the right.

The base game flow is straightforward, focused on lining up 7s and Bells for the high-paying wins. However, the real focus is on landing the diamond Bonus symbols. The entire rhythm of the game is built around the anticipation of triggering one of its many features, making the base game feel more like a setup for the main event.

Symbols, Payouts, and Special Roles

The paytable is simple and harks back to its classic roots.

• Wild Symbol: The flaming Wild 777 is the highest-paying symbol, awarding 30x the bet for a 3-of-a-kind match (it only appears on reels 1 and 3). It substitutes for all regular symbols, but not the Bonus or Power Bonus symbols.
• High-Pay Symbol: The golden Bell is next, paying 10x the bet for a 3-symbol match.
• Low-Pay Symbols: The card suits—Purple Spades, Red Hearts, Green Diamonds, and Blue Clubs—serve as the low-tier symbols.
• Bonus Symbol: A standard diamond symbol that carries a cash value. These are crucial for triggering the main bonus.
• Power Bonus Symbol: A special diamond symbol that lands only on reel 2. This symbol is the key to the game's biggest features.

The Electric Icons: A Symbol Deep Dive

While the symbols look standard, they serve a specific purpose in this Money theme game.

Symbol	Its Role in the Game
Wild 777	This isn't just a Wild. By landing only on reels 1 and 3, its role is to bridge gaps, but it's intentionally scarce. It represents the “classic” part of the slot.
Bell	The classic high-pay symbol. It's the most valuable win you can get on a standard payline, a nod to the old-school Vegas-style machines.
Diamonds (Bonus)	These are the game's lifeblood. They aren't just scatter symbols; they are the currency of the bonus rounds, carrying tangible bet multiplier values.

How to Trigger the Bonus Game

To start the Bonus Game, you must land at least one Bonus symbol on each of the five reels in a single spin. This is a key difference from typical Hold and Win slots that require 6+ symbols anywhere.

This 5-symbol requirement makes the Pile of Diamonds Feature essential.

What is the Pile of Diamonds Feature?

This is a random “helper” feature in the base game. When one or more Bonus symbols land, they might randomly activate the Pile of Diamonds.

When this happens, the game adds a quantity of Bonus and Power Bonus symbols to the reels. This significantly increases the chance of filling all 5 reels with symbols and triggering the main Bonus Game. In the demo, you'll see this as a sudden cascade of diamonds that often leads directly into the bonus.

Inside the Diamonds Power XXL Hold and Win Bonus

This is the game's version of a Hold and Win round. Once triggered, you are taken to a new grid where only Bonus symbols, Power Bonus symbols, and blanks can land.

You start with 3 re-spins. Any new symbol that lands becomes sticky and resets the re-spin counter back to 3. The round continues until you run out of re-spins or fill the entire grid. The regular Bonus symbols land with cash values of 1x, 2x, 3x, 4x, 5x, 6x, or 8x the bet.

The Power Bonus Symbol: The Key to Jackpots

The Power Bonus symbol is the star of the show. During the Bonus Game, any Power Bonus symbols that were on the triggering spin (or that land during the re-spins) stick to reel 2 for the entire duration of the round.

This is where the game's design shines. This sticky symbol on reel 2 is not just a placeholder; it's the engine for the Diamonds Power Feature.

Vlad's Expert Tip: “My first impression was to ignore the Power Bonus symbol and just collect regular diamonds. Big mistake. The entire math of this bonus round hinges on that sticky symbol on reel 2. It's a collector. Your goal isn't just to fill the screen; it's to feed that central collector symbol with as many other diamonds as possible.”

What is the Diamonds Power Feature?

This feature can trigger in both the Main Game and Bonus Game. It activates whenever one or more Power Bonus symbols land in combination with any Bonus symbol.

When it triggers, the Power Bonus symbol acts as a magnet, collecting the values from all other Bonus symbols on the screen. This is also how you win the four fixed jackpots:

• Mini Jackpot: 15x the bet
• Minor Jackpot: 30x the bet
• Major Jackpot: 100x the bet
• Grand Jackpot: 1,000x the bet

These jackpots can land as Bonus symbols and are then collected by the Power Bonus symbol when the feature triggers. In the Bonus Game, since the Power Bonus symbol is sticky on reel 2, it repeatedly collects the values of new symbols that land on every spin, including any jackpots.

What is the Game's Volatility, RTP, and Max Win?

This is a high-volatility slot. The base game can be quiet, with small wins, but the bonus features hold the potential for massive collections.

The RTP (Return to Player) is stated to be 95.7%. This is a fairly average figure, especially for a game with four fixed jackpots. The Max Win is tied to the jackpots and the collection potential, with the Grand Jackpot offering a 1,000x prize on its own.

The “Super Bonus” Paradox: Is 200 Bets Justified?

This is the real question I had testing the demo. The standard Bonus Buy costs 70x and gives you a Bonus Game with at least one Power Bonus symbol. The Super Bonus Game costs 200x—a massive jump—to guarantee at least three Power Bonus symbols.

Is it worth it? Honestly, it's a paradox. Three sticky collector symbols on reel 2 sound incredible. They would collect every single new diamond that lands. But at 200x the bet, the pressure to perform is immense. You need to land multiple jackpots or a screen full of high-value symbols just to break even. The 70x buy feels more balanced and is, in my opinion, a more practical way to experience the feature. The 200x buy is a pure “go big or go home” gamble.

Using the Bonus Buy Feature in the Demo

The best use of the Diamonds Power XXL free play version on Respinix is to test this exact buy feature. You can't get a real feel for the 70x vs. 200x dilemma without trying it.

Playing the demo allows you to run simulations. Try 10 standard buys at 70x and see the average return. Then, try 10 Super Bonus buys at 200x. This is the only way to build an instinct for the game's rhythm without risking any real money. It’s a perfect tool for strategy testing.

The Case Against Classic Themes: Is It Just Another Reskin?

Let's be blunt: the market is flooded with Playson slots that use the “Hold and Win” mechanic. When you first load this game, it's easy to dismiss it as another clone, a simple Retro-style slot with a new coat of paint.

And if you only look at the 777s and Bells, that argument is valid. However, the criticism falls apart when you look at the mechanics. The trigger (one symbol per reel) is different. The Pile of Diamonds pre-feature is a new layer. And the sticky collector Power Bonus symbol on reel 2 is a significant twist on the standard formula. It’s not just “Hold and Win”; it’s “Hold, Stick, and Collect.” This design choice makes it a very different beast from a simple spin-and-collect game.

Power Core: 3 Details You Might Have Missed

After spending time in the demo, a few subtleties stood out.

1. Wilds are Deceptive: The 777 Wilds only land on reels 1 and 3. This is intentional. It prevents easy 5-of-a-kind wins and forces the game's focus away from paylines and toward the scatter-based Bonus Game.
2. Reel 2 is Everything: The entire game, including the Super Bonus Buy, is built around reel 2. This central reel is the “Power” reel. Always watch it. A Power Bonus symbol here in the base game is more valuable than any 777.
3. Bonus Triggers vs. Power Triggers: You can trigger the Diamonds Power Feature (the collection) in the base game without triggering the Bonus Game. This can lead to nice “consolation” prizes, where a Power Bonus symbol on reel 2 and a Major Jackpot symbol on reel 4 land together for an instant 100x win.

Vlad's Expert Tip: “Don't get fixated on the 15 paylines. They are almost irrelevant. This is a bonus-hunt game. Your entire focus in the demo should be on understanding the cost-benefit of the 70x buy. For my money, it's one of the more interesting bonus buys Playson has released.”

Slots to Play if You Like Diamonds Power XXL

If the layered Hold and Win mechanic is what you enjoy, there are several other free demo slots on Respinix that hit a similar note.

• Mustang Gold: A Pragmatic Play classic. It features a similar “Money Collect” mechanic where specific symbols collect cash values on the screen, including jackpots.
• Money Train 3: If you want to see the “Hold and Win” concept pushed to its absolute limit, this Relax Gaming slot is the benchmark. It features over a dozen special modifier symbols in its bonus round.
• Le Bandit: This Hacksaw Gaming title has a unique “Golden Squares” collect feature that feels spiritually similar to the Diamonds Power mechanic.
• Pink Joker: Another slot from Playson that blends Classic slot visuals with a modern Hold and Win bonus, giving a good feel for the provider's general style.

You can browse hundreds of other games with different mechanics and styles in the full slot themes library to find your next favorite.

This game… it grew on me. I came in expecting a lazy, re-skinned classic slot and found a surprisingly intricate jackpot machine. Playson didn't just re-use their Hold and Win; they added new triggers, a pre-feature, and a sticky collector that fundamentally changes the bonus round's strategy.

Is it for everyone? No. If you want simple payline wins, this isn't it. The base game is a grind. This is a slot built for players who like high volatility and complex, layered bonus rounds. It's a typical Playson product in that it's polished and mathematically focused, but it's one of their more creative mechanical experiments. For me, it's a definite recommendation, but only if you have the patience for the bonus hunt.
