"The 777 Diamonds slot game from MrSlotty is an elegant affair with dazzling symbols on the reels, plus a blanket of gemstones glittering underneath the diamond-framed 5x3 reel set. A classical piece of music plays in the background while arcade-style sound effects are heard when spinning the reels. Our 777 Diamonds slot review explores the gameplay and bonus features. We also recommend the best online casinos and share the potential payouts, so you can make an informed decision before spinning for real money".

Hannah Smith’s take

"We found the 777 Diamonds online slot to be reminiscent of an old-school classic with 70’s style graphics and a rather plain backdrop. All the symbols are made out of gemstones, with premium payouts awarded by a black diamond of up to 1,000x your bet. Other symbols include a pair of cherries, a four-leaf clover, a gold bell, a trio of diamonds, a pair of gold jewels, and a diamond-encrusted number seven. A triple BAR represents the scatters, while a trio of diamond-encrusted lucky 7s acts as wilds. MrSlotty’s slightly over-complicated betting options confused us initially, but we soon got the gist. 777 Diamonds slot has 25 adjustable paylines and a lower-than-average 94% RTP rate".

Hannah Smith’s take

"The RTP rate is lower than average, at 94%. Triple BAR scatters trigger the 777 Diamonds free spins; land 3, 4, or 5 scatters to receive 1, 3, or 10 free spins, respectively. Every winning spin offers you the chance to gamble with your current win amount. Guess the next card's color to double your win and guess the suit to quadruple your win. But guess wrong, and you lose your current win amount".

Volatility

What does volatility mean?
What does volatility mean?Slot volatility indicates how large and how frequent you can expect payouts to be. The lower the volatility, the more frequently a game pays out, but the payouts will be on the smaller side. The opposite is true for high volatility - the game pays out less often, but the payouts are larger.

Hannah Smith’s take

"All wins are multiplied by the coin value bet per line; 1 coin = $0.01, and values range from 1 to 100. 777 Diamonds slot has 25 adjustable paylines".

Hannah Smith’s take

"The free spins round triggered by scatter symbols brings a break from standard spins, giving you up to 10 free games with no additional cost. Another fun touch is the built-in gamble feature, which lets you risk your winnings after any successful spin — guess the next card correctly and you can double or even quadruple your payout. These simple but engaging mechanics give 777 Diamonds a layer of excitement beyond its elegant retro look".
