Diamond Explosion 7s at 1Win: Vintage Vegas Glamour With Three Explosive Bonus Layers
1Win adds genuine vintage Las Vegas energy to its casino catalog with Diamond Explosion 7s — a sparkling RubyPlay creation that wraps classic slot iconography in a layer of shimmering diamonds and backs it with three independent bonus systems that work during both base game and Free Spins. Released in July 2022, this 5×3 slot runs across 50 fixed paylines with an outstanding 96.82% RTP and a maximum win of 8,000x the stake. The Link It Up Explosion feature activates when six or more diamond symbols land, merging them into larger shapes for elevated payouts. The Jackpot Pick Deluxe mini-game can trigger randomly on any spin containing a wild. Free Spins deliver a dedicated Wild reel and retriggering potential. For players who enjoy a classic fruit machine aesthetic paired with a feature set rich enough to sustain long sessions, Diamond Explosion 7s delivers on every front.
What Diamond Explosion 7s Brings to the Table
RubyPlay built Diamond Explosion 7s around a deliberate tension between old and new. The symbol vocabulary — fruits, bells, bars, lucky sevens — is drawn directly from mechanical slot heritage. The golden-framed reel cabinet, the stage-curtain background, and the classic Vegas lighting effects all reinforce a presentation that looks like it belongs in a physical casino. Yet under that surface sits a bonus architecture that no mechanical slot ever contained: a Link & Win-style explosion feature, a randomly triggered jackpot pick mini-game, and a Free Spins round where an entire reel transforms into wilds.
The diamond theme connects these elements visually. Most symbols in the game are rendered in virtual diamond form — shimmering versions of the classic fruit and bar symbols that give the entire paytable a unified, premium appearance. The diamond symbols specifically are not just decorative; they are the trigger mechanism for the Link It Up Explosion feature and serve as wild substitutes throughout regular play, making them the most strategically significant symbols on the reels.
The 96.82% RTP is one of the strongest in the classic-adjacent slot category and stands significantly above the industry average — a practical advantage that makes every session mathematically more favorable than most comparable titles.

The 96.82% RTP is notably high for a slot of this format — most classic-style titles operate between 95% and 96.5%, placing Diamond Explosion 7s in the top tier of its category. Medium volatility ensures that the session experience delivers consistent activity rather than extended lean stretches, with feature triggers distributed regularly enough to maintain engagement throughout.
Symbol Structure and Paytable
Diamond Explosion 7s uses a 50-payline structure with winning combinations forming left to right from the leftmost reel. Three or more matching symbols on any active payline qualify for a payout, with diamond and logo wild symbols capable of substituting into combinations to elevate them.
Premium symbols at the top of the paytable include the lucky seven and bell, rendered in the signature diamond style that gives the game its visual identity. These deliver the highest non-jackpot payouts for three-of-a-kind through five-of-a-kind combinations across the 50-payline grid.
Mid-tier symbols are the classic fruits — watermelon, grapes, plums, oranges, lemons, and cherries — all rendered as diamond-encrusted versions of their traditional forms. Their diamond coating is more than visual: these symbols count toward the six-diamond threshold that activates the Link It Up Explosion feature.
The Diamond Explosion 7s logo wild is the most mechanically significant symbol in the game. It substitutes for all paying symbols in standard winning combinations and additionally serves as a random trigger for the Jackpot Pick Deluxe mini-game on any spin where it appears.
The Horseshoe scatter triggers Free Spins when three or more land on the reels, paying a bonus prize directly regardless of payline position in addition to activating the round.
Link It Up Explosion: The Flagship Feature
The Link It Up Explosion is Diamond Explosion 7s’s primary bonus event and the mechanic that most distinguishes it from standard five-reel classic slots. It activates when six or more diamond symbols land in a single spin — a threshold achievable across any positions on the 5×3 grid rather than requiring specific payline alignment.
How the feature works: when six or more diamond symbols trigger the event, they merge together to form larger combined shapes. The merging process creates bigger diamond formations whose prize values scale with the size of the shape created. Larger merged diamond groups deliver proportionally higher payouts than the sum of their individual symbol values would suggest — the merging mechanic is designed to reward large diamond landing events significantly.
Feature within feature: one of the most notable mechanical details is that the Link It Up Explosion can trigger inside the Free Spins round as well as the base game. This nesting capability means that a diamond cluster landing during Free Spins — already an enhanced environment due to the Wild reel — can activate the explosion feature within the bonus context, with the Wild reel’s presence potentially contributing to a larger diamond formation than would occur during base-game play alone.
Frequency: RubyPlay designed the Link It Up Explosion to trigger with meaningful regularity rather than reserving it as a rare jackpot-tier event. Sessions where the feature fires multiple times across an extended play period are part of the intended gameplay rhythm rather than exceptional outcomes.
Jackpot Pick Deluxe: Random Mini-Game With Four Tiers
The Jackpot Pick Deluxe feature adds a random bonus dimension that operates independently of both the Free Spins and Link It Up Explosion triggers. Any logo wild landing on the reels can activate it at random — the activation is not guaranteed on every wild appearance but remains possible on any spin where the wild is present.
How it works: when triggered, the Jackpot Pick Deluxe presents a coin-selection mini-game. Players choose coins from the display, with each selection revealing either a cash prize or one of four jackpot designations. Matching three identical reveals awards the corresponding prize:
| Jackpot Tier | Multiplier Payout |
|---|---|
| Mini | 10x stake |
| Minor | 15x stake |
| Major | 50x stake |
| Grand | 50x stake |
The four-tier jackpot structure provides clear outcome targets within the mini-game. The Grand and Major jackpots at 50x represent the highest jackpot picks available, and while the multiplier values are fixed rather than progressive, their random accessibility on any wild-containing spin creates persistent session anticipation — every logo wild appearance is a potential jackpot pick activation regardless of the base game context.
Free Spins: Wild Reel and Explosion Potential
Landing three or more horseshoe scatter symbols anywhere on the reels awards eight Free Spins and a direct scatter payout. The Free Spins round introduces a mechanical enhancement not available in the base game: one reel is designated as a Wild reel for the duration of the feature, filling that column position with wild symbols on every spin.
Wild reel impact: a full column of wilds across five rows creates substitution coverage across every payline running through that reel position. With 50 paylines active and a wild-stacked reel guaranteed, winning combination opportunities during Free Spins are significantly elevated compared to base game equivalents at the same symbol distribution.
Retrigger mechanic: landing three or more scatter symbols during the Free Spins round retriggers the feature, adding additional spins and extending the Wild reel period. Multiple retriggers within a single feature activation create the session’s most consistently elevated outcome environment.
Cross-feature interaction: as noted in the Link It Up Explosion section, diamond symbols landing during Free Spins can still activate the explosion feature. The Wild reel’s presence during these spins means that the wild substitutions potentially contribute to larger diamond formations than base-game triggering conditions — making diamond cluster events during Free Spins the most high-value outcomes the game regularly produces.
Visual Design and Audio
RubyPlay executed Diamond Explosion 7s’s vintage Vegas aesthetic with genuine attention to presentation quality. The golden reel frame, stage curtain background, and ambient casino lighting create a setting that communicates old-school glamour without feeling dated — the diamond rendering of classic symbols modernizes the visual palette while preserving the iconic imagery that defines the format.
Symbol animations are polished throughout. Winning combinations trigger coin-shower effects and brief celebratory sequences, while the Link It Up Explosion merging sequence delivers the game’s most visually spectacular moment as diamond clusters combine into enlarged formations. The Jackpot Pick Deluxe coin flip animations add appropriate mini-game theater.
The soundtrack creates a layered audio experience. Base game music maintains a classic Vegas lounge rhythm, with distinct audio escalation during bonus events. Beethoven’s “Ode to Joy” plays on significant wins — a touch borrowed from classic land-based slot tradition that adds memorable audio identity to major payout moments. Sound effects for individual wins, wilds, and scatters are cleanly differentiated and avoid the repetitive fatigue common in extended-session slot audio.
Turbo mode is available for players who prefer a faster spin pace, reducing animation duration without eliminating win celebration sequences entirely.

Strategic Approaches for Diamond Explosion 7s
Diamond Explosion 7s runs on certified random generation. No spin outcome is influenced by previous results. Strategic value applies to session structure, stake management, and feature interaction awareness.
Diamond symbol monitoring. The Link It Up Explosion requires six diamonds to trigger. During base-game play, spins where four or five diamond symbols appear signal proximity to the explosion threshold. Recognizing these near-trigger spins helps calibrate stake-timing decisions — some players prefer to maintain or briefly increase stake when diamond frequency is elevated within a session.
Wild appearance awareness. Every logo wild is a potential Jackpot Pick Deluxe trigger. Since the activation is random rather than guaranteed, the only structural approach is maximizing the number of spins containing wild appearances. Longer sessions at consistent stakes produce more cumulative wild occurrences and more Jackpot Pick Deluxe opportunities.
Free Spins extension value. Retriggers during Free Spins extend the Wild reel period and create additional Link It Up Explosion opportunities within the bonus context. Sessions where Free Spins retrigger twice or more produce the longest continuous Wild reel coverage and the highest probability of in-bonus explosion triggering.
RTP-based bonus utilization. At 96.82% RTP, Diamond Explosion 7s offers the strongest theoretical return among the classic-style slots reviewed in this catalog. Using 1Win welcome bonus funds and weekly cashback credits here delivers better mathematical value than applying those funds to lower-RTP titles. The bonus balance effectively supplements an already favorable base return.
Bet range flexibility. The $0.50 to $100 bet range covers every budget tier. At $0.50, the 8,000x maximum win ceiling delivers $4,000; at $100, it reaches $800,000. Players whose session goal centers on significant absolute payouts benefit from stakes toward the upper range within their bankroll tolerance.

How Diamond Explosion 7s Compares to Similar Games
Diamond Explosion 7s vs. Double Hot. Both are classic-aesthetic slots with multiplier mechanics available at 1Win. Double Hot uses a full-board identical symbol trigger for its 2x multiplier; Diamond Explosion 7s spreads its bonus potential across three independent systems triggered by different symbol events. Diamond Explosion 7s carries a significantly stronger RTP at 96.82% versus Double Hot’s 96.07%, and the jackpot pick mini-game adds a dimension entirely absent from Double Hot’s feature set.
Diamond Explosion 7s vs. Fortune Five Double. Fortune Five Double’s x2 multiplier symbol applies during standard payline play; Diamond Explosion 7s’s Link It Up Explosion requires a six-diamond cluster event. Both include jackpot tiers — Fortune Five Double’s are triggered by red seven paylines, Diamond Explosion 7s’s activate via wild-triggered random mini-game. Diamond Explosion 7s’s 96.82% RTP is stronger than Fortune Five Double’s 96.11%.
Diamond Explosion 7s vs. Japanese Coin: Hold the Spin. Japanese Coin concentrates its highest payouts inside the Hold the Spin respin sequence and tiered Free Spins; Diamond Explosion 7s distributes its bonus potential across three independent trigger mechanisms active throughout every session. Japanese Coin’s 96.01% RTP is below Diamond Explosion 7s’s 96.82%. Players who prefer structured bonus progression favor Japanese Coin; players who prefer multiple independent bonus layers active simultaneously favor Diamond Explosion 7s.
