Diamond Dozen Slot Game Review

Diamond Dozen Slots Review for 2018

RTG's Diamond Dozen slot machine clings to the old adage that diamonds are a girl's best friend; play this slot right, and you'll probably agree. In format, the Diamond Dozen slots are strictly old business with five reels and 20 paylines and a max bet of one credit per line, but the game looks very fresh with its skyline backdrop and sparkling symbols.

Players can enjoy the elegant Diamond Dozen online slots for as little as a penny or can bet all lines at the max denomination of $5 for the top shelf price of $100 per spin. This gives choosy players a huge amount of control over the total amount of money that’s going out per spin, that’s great for players that like to play at a level they are most comfortable with. The good news is that regardless of how high (or low) you're rolling at your Diamond Dozen slots casino of choice, all players are eligible for the game's random progressive jackpot. Many slots will exclude players that don’t bet the maximum while playing from the progressive slot.



The Diamond Dozen slot machine gets its bling from the white diamond wilds, blue diamond scatters, jewelry, a sharp-dressed couple and a bevy of bejeweled 9-A symbols. The Diamond Dozen slots share the wealth, too, with several worthwhile payouts. The biggest prize is 3000 coins for five white diamond wilds, and while it's not the largest jackpot out there, the fact that the game also offers several other 1000+ coin prizes, two bonuses and a progressive jackpot makes it a pretty appealing play. Players aren’t going to get rich from a single jackpot, but it’s possible they can cash in nicely from a stream of them one after another.

30 Second Guide

Diamond Dozen has a glamorous theme with an old-school design style that fits the pattern of many popular online slots games from Real Time Gaming. It has five reels that can have a maximum of 20 lines active for combinations that start from the first reel on the left and continuing to the right.

The golden buttons make it simple to set the bet and the number of lines before spinning to get the winnings. Help is provided by wild symbols, shown as the large white diamond, and scatters represented by the blue diamond that can award free games.

At any Diamond Dozen slots casino, three consecutive blue diamond symbols on an active payline triggers 12 free spins at 2x. It also awards the player with a scatter pay of 2-100x their total bet. Additionally, three or more white diamond wilds trigger the special Diamond Delight online slots feature wherein players click on each wild to reveal a number between 1 and 10; those numbers are multiplied by each other and then the line bet to determine your final prize. What's extra cool about the Diamond Dozen slot machine is that the Diamond Delight feature can also be won during your free spins, and since more diamond symbols are added in the bonus round, doing so is especially easy.

To sum it up Diamond Dozen is all about building up jackpot and bonus combos rather than releasing massive prizes to players. There is a pretty small progressive jackpot, as well as a bunch of bonus and prize features that can really add up quickly. Players that give the slot machine a try will be surprised at how often they are winning, and that’s the main reason it’s such a fun option to consider.

Cherry Red and Slots Oasis offer the Diamond Dozen online slots to all their eager players (even Americans). We rate this classy game a sparkling 9 out of 10.

Jackpot Breakdown

The Random Jackpot is always shown on the main screen. While it starts at $1,000, it can quickly increase to go up to about $10,000 as players place their bets. Winning it is kept very simple since any spin can trigger the jackpot randomly, without having to get certain symbols.
