Expansion of Diamonds Slot Review & Free Play

Expansion of Diamonds: Merge Diamonds and Stars for up to 500x Payouts

Synot Games is back with another classic slot entry with the Expansion of Diamonds game. Inside these reels are symbol pays up to 500x your bet, wilds that expand to cover an entire reel, and scatters that pay up to 100x rewards anywhere on the reels. Let’s go through the mechanics and features of this slot to find out whether you should play Expansion of Diamonds for free. 

The game plays out on a familiar 5-reel, 3-row setup with 10 paylines and a low to medium volatility level. Wins start at 1x your bet and can reach an impressive 500 times your bet which was a welcome addition. With fewer paylines in play, I quickly noticed that this slot leans more toward bigger payouts that don’t come around too often, even though the volatility isn’t super high here.

In my session, it took me anywhere from three to seven spins to land symbol combinations and most of them came in between 1x to 2x my bet. Even with higher symbols, I struggled to get payouts higher than 5x my bet. This slowly began draining my bankroll until I started landing wild symbols on the reels. Wilds are the star of the show here and don’t come around often but when they do, they definitely announce themselves in style. 

When a wild symbol lands, it expands to fill the entire reel. I frequently hit pairs of wilds on adjacent reels, which helped me rack up returns between 12x to 20x thanks to the generous symbol payouts in the Expansion of Diamonds slot. Since the game doesn’t include a traditional free spins feature despite having scatter symbols, these wilds carried most of the weight and even landed me a small profit now and then.  

The slot also features a gamble option that lets you double your winnings. It revolves around an upside-down card, where you have to guess whether it’s red or black. A correct guess doubles your payout with a 2x multiplier. It was a nice way to boost smaller wins, but I mostly avoided it since the wilds were already bringing in solid payouts on their own.

In my view, the Expansion of Diamonds slot delivers a quick and enjoyable gameplay loop that gets exciting once the expanding wilds start landing. The symbol payouts are much higher than what you’d find in similar classic slots, making each win feel more rewarding. If you're looking for a straightforward slot with no unnecessary distractions or just want something fun to pass the time, playing Expansion of Diamonds for free might be worth a shot.
