Stellar Diamonds by Playtech pairs familiar fruit symbols with a cosmic backdrop and five reel-specific features. Diamonds act as wilds, but they can also open safes, activate multipliers or start free games.
Among our slot games, this one gives us a reason to watch where a symbol lands. The same Diamond can produce a different effect on each reel.
A purple space backdrop surrounds a reel set filled with cherries, lemons, bells and red sevens. The blue Diamond stands out against these traditional symbols, matching the illuminated reels that signal a Blue Hot Zone.
Feature icons above the columns make their roles visible. The presentation mixes a classic fruit-machine appearance with a galactic setting, keeping the symbols large and easy to distinguish.
Before a base-game spin, one or more reels can turn blue. A Diamond landing on a highlighted reel guarantees its associated feature. Diamonds on other reels can still trigger features, but activation is not guaranteed.
A Diamond on reel one can activate SAFE, presenting twelve safes to open. Each reveals a prize label, and finding three matching labels awards the corresponding prize.
Mini, Minor, Major and Grand begin at 10x, 20x, 50x and 100x total bet respectively. Diamonds on reels one and five can increase their values. These prizes are awarded through SAFE.
When reel two’s feature activates, the entire reel fills with x2 Diamond wilds. Winning combinations that use them are doubled.
Reel four’s feature fills that reel with x3 Diamond wilds. Wins using them are tripled, while combinations containing both x2 and x3 wilds receive a combined 6x multiplier.
Reel three’s feature awards five free games and expands the grid to five rows with 50 paylines. Reels two and four remain Blue Hot Zones, allowing Diamonds to trigger their multiplier features.
Symbols marked +1 or +2 add that many free games. SAFE, Prize Wheel and the reel-three feature do not activate during this round.
Reel five can turn into a wheel awarding 5x, 8x, 10x, 15x, 25x, 40x, 80x or 120x total bet. It can also award entry to SAFE or Free Games.
The base game uses five reels, three rows and 25 paylines. Matching symbols form line wins, with the Diamond helping complete combinations as a wild.
The main change arrives during free games, when two additional rows open and the payline count doubles. We also have guaranteed Hot Zones on the two multiplier reels throughout that feature.
We think Playtech’s reel-by-reel feature arrangement is the strongest part of Stellar Diamonds. Once we know which column does what, the Blue Hot Zones make each spin easy to follow.
The expanded free games give the multipliers more room to work, while SAFE and Prize Wheel add variety to the base game. Within our online casino, it offers a familiar fruit-slot appearance with more features to learn than the symbols initially suggest.
