The Diamond Queen slot game is made by IGT - the company behind WagerWorks casinos. IGT publish the house edge of their slots games with the paytable, however if the game has a range of possible settings, this figure is usually only given only as a range. Check with the casino you are playing at to find out if they give the exact value or range of possible values. The house edge of Diamond Queen is between 3.92% and 7.03%. Unless you are playing at a casino that explicitly states the house edge they are using it would be wise to assume you are playing against a 7.03% edge.
The Queen of Diamonds has always brought wealth.
This game is a 5 reel game with 20 paylines and you can bet one coin on each payline.
The ‘Diamond Queen' symbol is wild.
There is only one bonus feature available when playing Diamond Queen and it is activated when you receive 3 of the 'Mystical Diamond Bonus' symbol on reels 2, 3 and 4. When this happens you will be awarded 3 complimentary spins. During spin one reel 2 is wild, spin two reels 2 and 3 are wild and spin three reels 2, 3 and 4 are wild. During the complimentary spins if you receive the 'Extra Spin' symbol you receive an extra free spin the same as the spin that you received the Extra Spin symbol.
Conclusion
The complimentary spins don't happen often but offer the chance of some really big wins which is exciting, but the house edge uses leaves a horrible taste in the mouth.
