Theme and Graphics

This highly-stylistic game sees a series of brightly coloured and differently cut gems, which stand out against a starkly black background. The reels have a gold outline and above the reels the game logo appears, also in gold. The gems in the reels include rubies, amethysts, emeralds, diamonds, beryls, garnets and sapphires. The musical score has a futuristic, electronic sound. The association with gems and luxury lifestyles makes it a popular choice in slot games, and if you like the gem theme you’ll find many other games with a similar stylistic theme.

Poly Diamonds RTP and Variance

RTP: 95%
Volatility: Medium-high

The game’s return to player (RTP) is 95%, around the slot industry average and nothing to get too excited about. However the game’s medium to high volatility ensures a thrilling ride, and makes it perfect for high rollers and experienced slot players who prefer to walk on the wild side than stick in the slow lane. 

How to Play Poly Diamonds

  1. Navigate to the lower right-hand side of the reels and choose a coin value of between 0.01 and 1.00.
  2. After you’ve selected a coin value, look to the left and choose a bet level of 10-100. These 2 amounts will be multiplied together to give an overall bet, which applies across the 27 paylines. 
  3. Either side of the spin button are 2 useful function buttons; a max bet and an autospin function.
  4. To the top left hand corner are the game settings, including a volume control and full screen option, as well as access to the paytable. 
  5. When you are ready to get started, simply hit the large spin button that you will find located directly below the reels. 

Please play Poly Diamonds responsibly by setting yourself an affordable and sensible budget for each play session. Never chase losses and ensure you stick to your limits. When the fun stops, stop.

Poly Diamonds Bonus Features 

Bonus Game/Free Spins

The free spins bonus game is activated by landing 3 or more ring scatters. The number of free spins awarded is as follows:

3 Ring Scatters = 10 free spins
4+ Ring Scatters = 15 free spins

Expanding Wild

The wild symbol substitutes for all other symbols with the exception of the scatter. It also expands up and down the reel that it lands on AND triggers a respin with the expanded wild held in place. Any wilds that land during a respin will also expand, but will not trigger another respin. 

Overall Poly Diamonds Review

This is a gorgeous-looking game with bold, sparkly graphics, set perfectly against a luxurious black background. But looks aren’t everything and most players, us included, are more interested in how good the bonus features are. The free spins feature doesn’t offer anything extra, but players can enjoy up to 15 free spins. More exciting perhaps is the respin feature that always comes with a stacked wild. The game has an uninspiring RTP, but the medium to high volatility ensures excitement. And the best news is… you can enjoy Poly Diamonds for free here at Slots Temple, where you can access it from a screen of your choice, whether you want to play in the palm of your hand on your mobile phone, or you want to sit up at a desktop computer.

Also available for free, this slot game blends the gem theme with renaissance art and is one of the highest rated slot games of all time. It’s also just one of hundreds of slot games that has a free spins bonus at its core.
