Diamond Queen is a five reel and three row online slot game from IGT. If you have ever been to a land-based casino, you may have played this classic. There are 20 pay-lines on this highly volatile game which has an RTP of 94.89%.
Features include Free Spins, Scatters, all Wild Reels and Wilds and you’ll see the Queen, wizards, diamonds, tiaras, sceptres, page boys and playing card symbols across the reels.
Diamond Queen launched in May 2012.
Diamond Queen is one of our favourite IGT’s slots. It’s a real classic, and would fit in to any Best IGT Slots list in our view.
This is already a hit in many land-based casinos- you have probably seen it if you have ever been to Las Vegas. It has a magical fairy-tale theme, with gemstones, diamonds and tiaras (it’s along the same lines as IGT’s Da Vinci Diamonds slot in this respect).
There’s a 1,000 coin jackpot which you trigger by landing five Diamond Queen logos. The bets go from 0.20 a spin to 200.00 a spin (in your home currency).

The main draw in this slot game are the Mystical Diamond Free Spins which you can set off by landing three Mystical Diamond Bonus symbols on the middle reels (2, 3 and 4).
– This nets you three free spins and if the Extra Spin symbol appears on reel 1, you get one more free spin (you can collect up to 20 free spins this way, giving you a target of 23 free spins to go for).
– PLUS (and here comes the interesting bit), the free spins bonus round starts with reel 2 completely wild for the initial spin.
– The 2nd spin has wild 2nd and 3rd reels and the 3rd free spin has the 2nd, 3rd and 4th reels wild.
As you can imagine, this results in quite a bit of “kerching, kerching, kerching” action. This is what makes this game so appealing.
Diamond Queen is high volatility (a high variance slot). So this means that you may have to get through some slow patches (make sure you have enough bankroll to cover these). But when it does start to pay out, this slot can go on a nice run.
The bonus feature doesn’t come along as often as other slots, but when it does, it’s generous.
All in all, we’d say that this slot is Diamond, but then we like high variance slots. It is certainly one of IGT’s most entertaining games in our book, and fits well with IGT’s other classics like their Siberian Storm Slot Machine, Cleopatra and the Treasures of Troy Slot.
