Diamonds Power XXL: Hold and Win by Playson represents an evolution in the Hold and Win slot category by introducing the innovative Power Bonus Symbol that fundamentally changes how bonus values accumulate. This 5-reel, 3-row video slot with 15 fixed paylines combines classic diamond-themed visuals with a sophisticated dual-bonus system that creates multiple paths to significant wins.
The defining mechanic of Diamonds Power XXL is the Power Bonus Symbol, which exclusively lands on reel 2 during both base and bonus games. When this golden diamond appears alongside any blue Bonus Symbol on reels 1 or 3, it triggers the Diamonds Power Feature. This feature immediately collects and adds the values of all visible Bonus Symbols to your current win, including any jackpot symbols present on the reels.
Critical Mechanic: The Power Bonus Symbol creates instant value collection. If you land a Power Bonus on reel 2 with multiple Bonus Symbols showing values of 2x, 5x, and 8x bet, plus a Major Jackpot symbol, the Power Bonus instantly collects all these values (2+5+8+100 = 115x your bet) and adds them to your spin win.
Playson implemented a safety mechanism: if the Power Bonus lands without any Bonus Symbols visible, the game may randomly add Bonus Symbols to activate the feature. Conversely, if Bonus Symbols land without the Power Bonus, a Power Bonus may be randomly added to reel 2. This ensures the feature triggers more frequently than pure random chance would allow.
The traditional Hold and Win bonus activates when at least one Bonus Symbol lands on each of the five reels simultaneously. This transitions you to a dedicated 5x3 grid where only Bonus and Power Bonus symbols can appear. You receive 3 re-spins, and each new symbol that lands resets the counter back to 3.
During the Hold and Win bonus, Bonus Symbols display fixed bet multipliers: 1x, 2x, 3x, 4x, 5x, 6x, or 8x your bet amount. The Power Bonus Symbol, still exclusive to reel 2, sticks to the reels and accumulates values throughout the bonus round. When the bonus concludes (either by filling all 15 positions or exhausting re-spins), all accumulated values in Power Bonus symbols are added to your total win.
Four jackpot tiers can randomly appear as special Bonus Symbols during the Hold and Win feature:
| Jackpot Tier | Bet Multiplier | Trigger Method |
|---|---|---|
| Grand Jackpot | x1000 | Random appearance as red diamond symbol during bonus |
| Major Jackpot | x100 | Random appearance as green diamond symbol during bonus |
| Minor Jackpot | x30 | Random appearance as blue diamond symbol during bonus |
| Mini Jackpot | x15 | Random appearance as purple diamond symbol during bonus |
These jackpot values are fixed multipliers of your bet amount, not progressive pools. At a 1.00 bet, the Grand Jackpot pays exactly 1000.00. The jackpot symbols can land on any position during bonus spins and contribute to the total win calculation.
For players who prefer immediate bonus access, Diamonds Power XXL offers two distinct purchase options accessible via the orange Bonus button with shopping cart icon:
The Super Bonus option significantly improves win potential because multiple Power Bonus symbols each accumulate values independently throughout the bonus round. If you land a Bonus Symbol worth 5x bet with three Power Bonus symbols active, each Power Bonus collects that 5x value, effectively tripling its contribution.
Any Bonus Symbol landing during base game spins has a chance to trigger the Pile of Diamonds Feature. When activated, the game automatically adds enough additional Bonus Symbols (and potentially Power Bonus symbols) to the reels to meet the requirement for bonus activation: at least one Bonus Symbol on each reel. This creates surprise bonus entries during regular play.
Two wild symbols appear in the base game:
Regular paying symbols include golden dice (8.00 for 3), BAR symbols (4.00 for 3), mixed card suits (1.00 for 3), and blue clubs (0.50 for 3). All pays require three matching symbols on any of the 15 fixed paylines running left to right.
The 15 paylines include three straight horizontal lines (top row, middle row, bottom row) plus twelve geometric patterns creating V-shapes, W-shapes, M-shapes, and various zigzag formations across the 5x3 grid. All paylines are permanently active and included in every bet. With a 1.00 total bet, approximately 0.0667 is wagered per line.
The bet range from 0.20 to 100.00 allows 14 different bet levels. Because jackpot values are fixed multipliers, a higher bet directly scales your potential jackpot wins. At the maximum 100.00 bet, the Grand Jackpot would pay exactly 100,000.00.
The buy bonus features become increasingly expensive at higher bets. At 100.00 bet, the Standard Bonus costs 7,000.00 and Super Bonus costs 20,000.00. These features guarantee bonus entry but not specific outcomes, so they represent high-variance plays suitable for players with substantial bankrolls who want to experience the Hold and Win mechanics without waiting for organic triggers.
Maximum value extraction in Diamonds Power XXL comes from understanding when Power Bonus symbols appear. Since they only land on reel 2 and stick during bonus rounds, every Power Bonus that lands early in a bonus game has more opportunities to collect values from subsequently landed Bonus Symbols.
The Super Bonus purchase option at 200x bet provides the best guaranteed value when seeking major wins, as multiple Power Bonus symbols create multiplicative collection effects. However, organic bonus triggers offer better value for extended play sessions, as the 70x and 200x costs represent significant portions of typical bonus payouts.
The Pile of Diamonds feature essentially functions as a random bonus trigger that reduces the actual hit frequency barrier. Players should account for this when calculating expected bonus frequency, as the published trigger requirement (one Bonus Symbol on each reel) can be artificially created by this feature even when not naturally occurring.
Diamonds Power XXL operates on version 0.366.0 with a fixed 15-payline structure that cannot be adjusted. The left-to-right payline evaluation means symbols must connect from reel 1 consecutively to count as wins. Only the highest win per payline is paid, and all wins are calculated as multipliers of the total bet amount divided across the active lines.
The bonus game mathematics favor filling more positions. A completely filled 15-position grid with average Bonus Symbol values of 4x bet would yield approximately 60x bet before Power Bonus contributions. If three Power Bonus symbols accumulated throughout the round, they could potentially double or triple this base value depending on landing sequence.
Responsible gambling notice: All pays and plays are voided in case of malfunction. The Hold and Win mechanic creates extended play sessions during bonus rounds which can consume significant time. Players should set time and loss limits before beginning play sessions, especially when considering buy bonus options that require upfront capital investment of 70x to 200x the base bet.
Among Playson's portfolio and the broader Hold and Win category, Diamonds Power XXL differentiates itself through the Power Bonus collection mechanic. Traditional Hold and Win games simply accumulate symbol values, but the Power Bonus system creates a secondary collection layer that can multiply total bonus wins significantly when multiple Power Bonuses are active.
The dual buy bonus system acknowledges different player preferences: casual players can access the feature at 70x bet with one guaranteed Power Bonus, while high-rollers seeking maximum potential can invest 200x bet for three or more Power Bonuses. This segmentation allows the same game to serve different volatility preferences through player choice rather than fixed game settings.
The visual presentation emphasizes the electrical energy theme through constant lightning effects and the orange-red color palette, reinforcing the power concept central to the game's identity. The diamond symbols themselves use the classic cut-gem aesthetic that has proven enduringly popular in casino gaming, while the golden and blue color distinction between Power Bonus and standard Bonus symbols creates instant visual differentiation of their functional differences.
