Slot machine details and review Poly Diamonds
Poly Diamonds is one of the titles from Czech developer Kajot Games, combining the traditional concept of a four-reel slot with modern visuals and a few surprising features. At first glance, the game looks like another classic fruit slot β but instead of fruit youβll find sparkling diamonds and luxury symbols that give this otherwise conservative format an interesting visual twist. Poly Diamonds has 4 reels and 3 rows, making it a classic slot, but it features 81 paylines, which means more frequent wins and easy-to-follow gameplay.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
A slot machine with low to medium volatility.Wins are fairly frequent and sometimes even a higher win. The game has a more balanced course without major fluctuations, suitable for players who want more frequent wins but also the chance to win more. More about volatility here.
Slot theme and symbols
Poly Diamonds feels elegant, clean, and subtly luxurious. The whole game is built around glowing gemstones, gold and silver elements, gentle animations, and a stylish backdrop. That sets it apart from classic fruit machines β here everything has a diamond shine and a sophisticated edge. The symbols on the reels include blue, yellow, purple and red diamonds, hearts and other shapes. The soundtrack is understated and never gets in the way β snappy spins and a soft electronic loop in the background. The sounds arenβt intrusive and help support the luxury atmosphere. The WILD symbol substitutes for other symbols (except the bonus Scatter) and helps create winning lines. If youβre lucky, you can also spin Scatter symbols, which bring plenty of fun with Free Spins. An RTP of around 95% is standard, though the competition sometimes offers more.

WILD symbol
The game also offers substitute bonus WILD symbols, which stand in for all other symbols except Scatter symbols to create the highest possible winning combination according to the Paytable. When a WILD symbol appears, it replaces all other symbols on the reel where it lands, and then all remaining reels spin once for free. If a WILD symbol appears again after this spin, it will once more replace all other symbols on its reel and can help form winning combinations, but no further free spin will be awarded!
Scatter symbol
The game features a bonus Scatter symbol. Landing three Scatter symbols anywhere on the reels during play triggers a bonus round with ten bonus spins. Four Scatter symbols trigger a bonus round with fifteen free bonus spins.
