Diamond Dozen

How to play

The Diamond Dozen slot action takes place on five reels and three rows, with 20 adjustable paylines. Look out for easy gameplay here, especially if you’re used to playing online slots.

You can select the number of paylines and your bet level before spinning the reels. You can choose between one and 20 paylines before you start playing, while your bet level has to be between €0.20 and €5. The bet level is mostly ideal for lower-budget players. Therefore, we imagine that the high rollers among you will not enjoy this one at all.  

You can click on the spin button after setting your bet levels. You can also go for autoplay if you want to play the game while you’re on the move. All winning combinations pay from left to right, except the scatters.

Symbols and payouts

The symbols on the reels of the Diamond Dozen slot fit the glittery and shiny theme that the game presents. The special symbols include the wild, which is the white diamond, and the scatter, which is the blue diamond. The wild will give you 3,000x, 1000x, 200x, 10x, and 2x your bet per line for landing five, four, three, two, and one across the reels. Then, the scatter will give you 100x, 10x, 3x, and 2x your total bet for landing five, four, three, and two.

The highest paying symbol is the man offering 2,000x, 500x, 100x, and 5x your bet per line for landing five, four, three, and two symbols on any of the paylines. Next is the woman offering 1,000x, 300x, 75x, and 3x your bet per line, and the diamond ring symbol with 500x, 200x, 50x, and 2x.

Then, the rose symbol will give you 300x, 50x, and 20x your bet per line for landing five, four, and three symbols across the reels. The purse symbol offers the same payout.

The game features low-paying symbols including A and K which will give you 200x, 25x, and 10x your bet per line, while Q and J will give you 150x, 20x, and 5x your line bet. Finally, 10 and 9 will give you 100x, 15x, and 5x for hitting five, four, and three of a kind.

Best Diamond Dozen bonus features

Although the slot is a bit old-school, you can look forward to some exciting rewards as you play. The Diamond Dozen bonus features will give you lucrative payouts and add some dazzle to the simplicity.

The slot features a wild which can replace all other symbols on the reels except the blue diamond scatter. It can help you land winning combinations.

Then, we have the Diamond Dozen free spins feature giving you a fun bonus round. If you land three or more scatters, which is the blue diamond symbol, from left to right on the reels, you win 12 free spins. During the free spins round, you get more blue diamond and white diamond symbols, as well as a 2x multiplier on all your wins.

Finally, the Diamond Delight feature is triggered when you land three or more white diamond symbols anywhere. If you touch each white diamond, you trigger a combination and it will reveal a number between one and 10. The number will be multiplied by your wins.

RTP & volatility

The Diamond Dozen RTP is set at a 97.50% RTP, which is way higher than the average for most slots out there. So, you can look forward to fairly good returns as you play the game. It also features low volatility, which means you can get frequent wins as you play this slot.
