GreatSlots review · Ruby Play · 2022
Diamond Explosion 7s looks like a classic sevens-and-fruit game, but the feature load is much heavier than the theme suggests. Wilds, prize symbols, free spins, and jackpot-style pick moments give it more pace than a basic 50-line slot.

GreatSlots score
4.2/5
Best for
players who want sevens and fruit with bonus depth
A feature-heavy classic slot for players who want familiar symbols with a bigger modern win ceiling.
Diamond Explosion 7s is a Ruby Play fruit-and-diamond slot with 50 paylines, medium-high volatility, two free-spin styles, and an 8,000x max win.
Diamond Explosion 7s uses five reels, three rows, and 50 fixed paylines. The symbol set is familiar, with fruit, sevens, and diamonds, but the game adds more feature symbols than a normal classic slot.
The upside comes from several routes rather than one main bonus. Scatters award free spins, Diamond Prize symbols can move the game into an explosion-style feature, and wilds can trigger a pick event. That makes it busier than it first appears.
Diamond Explosion 7s suits players who enjoy classic slot symbols but do not want classic slot limits. The RTP and max win make it more serious than the theme might suggest.
Players who want a very clean low-stakes slot may prefer Joker Pro or Sizzling Hot because Diamond Explosion 7s carries more feature detail and a higher minimum bet.
The mobile version is readable, but the feature icons matter. The grid itself is simple, while the paytable helps explain how the diamond and wild features differ.

RTP guide
RTP is useful only when it is read with volatility, max win, feature access, and the exact game version being reviewed.
Bonus guide
Free spins matter most when the trigger, retrigger rules, multipliers, and symbol upgrades are clear enough to compare before play.
Jackpot guide
Jackpot-led slots can be appealing because of the ceiling, but the review needs to separate jackpot upside from base-game value.
Megaways guide
Megaways slots need a different comparison because changing reel heights, cascading wins, and free-spin multipliers can reshape every round.
