Two Double Diamonds and a blank on the payline pay nothing: the wild in Double Diamond needs a Bar, a Seven or a Cherry beside it before it doubles or quadruples anything. My 300 spins at 1.00 went from 200.00 to 171.00, and the best line was three Double Bars at 25x, twice.
RTP rests at 95.44%, and I get 3 rows on each of the 3 reels and a sole payline. I played 300 spins at a stake of 1.00 credit, starting from a balance of 200.00 credits.
Symbols are composed of Cherries and Single, Double and Triple Bars at the bottom end, while bigger returns come from the high pay symbol - the Seven. Three Triple Bars pay 40x the stake, three Double Bars 25x and three Single Bars 10x. The Seven is the most valuable ordinary symbol. Three Cherries pay 10x the stake, two Cherries 5x and a single Cherry 2x, whatever reels they land on. The Seven will pay 80 times the stake for three of a kind. A mix of non-matching Bars on the payline makes an Any Bar win, which pays 5x the stake.
The Double Diamond symbol is the Wild, and it substitutes for any symbol. It only counts when the rest of the line holds a matching non-blank symbol or a Cherry, so two Double Diamonds next to a blank pay nothing. It fills in for a Cherry only when a Cherry is on the payline on another reel. Only the highest winner on the line is paid.
Unexpectedly, there is no main feature at all. Of my 300 spins, 39 paid, and none of them returned less than the stake. There are no free spins, bonus round, jackpot or feature buy. Over the session I wagered 300.00 credits and won back 271.00, a session return of 90.3%.
If a win contains one Double Diamond, it triggers a multiplier of x2 attached to that win. With one Double Diamond beside a Single Bar and a Triple Bar, the 5x Any Bar win doubles to 10x the stake.
Two Double Diamonds trigger x4, and three Double Diamonds award 1000x the stake. The doubled Any Bar landed six times in my session, and an Any Bar with two Double Diamonds paid 20.00 credits once, on spin 102.
The Minty Breakdown: The whole game hangs on one line, and at the top of it players are looking at returns of up to 1,000 times the stake in the base game. No three-Double-Diamond line landed in my 300 spins, and neither did a line of Sevens or Triple Bars.
I could have placed that figure in the opening line of the review. My biggest wins were two lines of three Double Bars at 25x, 25.00 credits each, on spins 111 and 214.
Another vital component of Double Diamond’s playability is the returns available during the base game, and by equipping the game with no bonus feature, symbol values have kept respectable value. The balance peaked at 232.00 credits on spin 119 and dropped to its lowest point of 166.00 on spin 78. That holds interest high during the base game. My longest run without a win was 30 spins, ending on spin 160, and I finished the session on 171.00 credits. Make no error.
