Graphics and Theme

When it comes to the theme for this slot, it is all about creating the atmosphere of a classy night out in an American city like Los Angeles, where money is no object. The designers achieve this in various ways. One of them is the background they use: a glittering bay with dotted sailboats and a lofty silhouetted skyline.  You could imagine this as any big exciting American city.  The board is encased, quite fittingly, in a gold case. Normal symbols are numbers and letters studded with a generous helping of diamonds.  Specials, on the other hand, comprise of both a male and female celebrity, gold and diamond rings, purses, and a romantic red rose. The various jewels’ frequency and stunning appeal give the whole game a feeling of value and high status. The music sounds like various instrumentals from Frank Sinatra’s ballroom songs.

How To Play Diamond Dozen Slot

Real Time Gaming makes setting up and playing Diamond Dozen easy with a range of betting options provided along the screen’s bottom. Using this menu, players can set the bet per spin and win and loss limits. Once these parameters are set, players may spin the reels. This can be done either by using the manual spin button or by setting up automatic spins. To win, players must match symbols across pay lines from left to right.

Diamond Dozen Slot Features

The most useful bonus to know about for this game is the Wild feature, a common feature of most online slot games. For this game, the white diamond symbol represents the wild. It has the ability to step in for any other symbol bar the scatter to help players win combinations. Its other ability concerns triggering the diamond delight feature. If you manage to land three of these symbols on the reels simultaneously, you will trigger this feature. When activated, each white diamond yields a random number between one and ten, by which the total winnings up to that point are multiplied by, acting as a single very influential bonus.

The other symbol to look out for is the blue diamond, representing the scatter for this game.  If three or more of these symbols appear on the reels, you will activate the free spins game. For the free spins game, players are given 12 free spins. All of the winnings earned during this feature are doubled at the end. The frequency of both the white and blue diamonds for the free spins round is also increased for the feature duration. This means players are more likely to trigger wins and add to their winnings pot.

There is also a progressive jackpot for this slot, which can be won on any spin of the slot completely at random. As you will notice from the number in the middle of the screen at the top, the progressive jackpot is always growing with other people’s wins. Only 1.5% of the total return to player percentage is contributed to the random jackpot.

That is the extend of the bonus features for Diamond Dozen. However, with a lot of high-value symbols and a high probability of triggering the features that there are, you are likely to do just fine without the need for an overabundance of features.
