Diamond Dozen Slot Review

Upon closer look at the Diamond Dozen Slot Review we see a well established slot game from RTG. Released years ago and still popular.

Established in 2010

Even though this slot has been around since 2010 it still has quite a following.

As part of their original releases for the Real Series video slots, this game still has many fans.

General Theme

The overall general theme of the game is a young couple and their courtship.

We he bring her a rose, or possibly place a ring on her finger? Will he get white diamonds or blue diamonds.

Spin to find out.


The game is a 5 reel video slot and has 20 paylines.

Choices in bet limits are generous as you can bet as low as $0.01 and as high as $5.00 per line.

The RTP on this game is 95% although I have seen a few site rate it a bit higher, but we think the 95% sounds correct.

Review the Slot Game Symbols of Diamond Dozen

The Diamond Dozen slot game symbols fit the theme extremely well.

You have the man as well as his sweetheart the blonde woman. There is a rose, presumably what he is carrying when he shows up for a date, and then there is the change purse she carries when they go out. Then there is the diamond engagement ring.

To fill out the rest of the regular game symbols are the A, K, Q, J, 10 and 9, each of them also having diamonds in them.

You will also see White Diamonds and Blue Diamonds as special symbols, see below for their explanations.

Game Symbol Match Payouts

When matching game symbols appear on paylines you will win the following payouts.

  • Gentleman Match 5 for 2000, 4 for 500, 3 for 100 or 2 for 5.
  • Woman, if you match 5 for 1000, 4 for 300, 3 for 75 or 4 for 3.
  • Diamond Ring matches 5 for 500, 4 for 200, 3 for 50 or 2 for 2.
  • Rose or the purse match 5 for 300, 4 for 50 or 3 for 20.

  • Q, J as you match 5 for 150, 4 for 20, 3 for 5
  • 10, 9 match 5 for 100, 4 for 15, 3 for 5.
  • White Diamonds if you match 5 for 3000, 4 for 1000, 3 for 200, and 2 for 10. Land 1 for 1.
  • blue Diamonds if you match 5 for 100, 4 for 10, 3 for 3, and 2 for 2.

Matches are counted left to right only on a payline. Symbols must be like symbols only.

White Diamond Symbols

The white diamond symbol will substitute for any symbol on the board, except blue diamonds.

This can certainly increase your wins.

White Diamond Delight Feature

Any time you get 3 or more white diamonds on the game board, you trigger the white diamond delight feature.

You then select the diamonds 1 at a time and they transition into a multiplier. Multipliers are from 1 to 10.

Once they are all selected, the multipliers are multiplied, left to right to come up with a final multiplier for the feature. That multiplier is multiplied by the bet that triggered the feature.

This feature can really be a nice win to boost your balance.

Blue Diamond Scatter

The blue diamond symbol is the scatter.

Landing a blue diamond n a winning payline will multiply the bet.

Blue Diamonds Free Spins

Plenty of diamonds to be had and when you get 3 or more blue diamonds on the game board the free spins are triggered.

During free spin rounds all wins are doubled.

The number of blue and white diamonds is increased during the free spin rounds raising your chances of wins. Free spins can be won during free spin rounds.

Progressive Jackpot

Yet another game from RTG that comes with the random progressive jackpot ticker.

The jackpot can be won at the end of any round totally at random. We have seen this climb well into the 5 figures. The day we reviewed the game it was a bit over $8000.

Instant Play Not Available

This particular game is not available for instant play in the browser version of the gaming suite.

It is available in the full download suite of games at any of your favorite RTG casinos.


To conclude we have mixed feelings about this game honestly.

We have always enjoyed the game and remember playing it years ago when it was released. We still like it today and enjoy playing it. The jackpot is nice.

Bonus rounds and free spins are triggered frequently enough in most gaming sessions, and the freedom in the bet amounts are nice also.

The fact that it currently is not available to those who like to play on the go, any time any where from the browser is certain a drawback. We would rate the game higher if it were available in the browser.

If you don’t mind the download option, you might find the game worthwhile. We actually like the feel of the download games at times, but understand some players may not like this option.
