  • Wild: Deco Diamonds is all about the wild symbol, and it’s the key to unlocking the re-spins and the bonus wheel. The fun begins when there are at least two wild symbols on the reels. Those reels will freeze while the others spin again. As long as new wilds are added to the reels, the re-spins will continue.
  • Scatter: There is no scatter symbol in Deco Diamonds
  • Bonus: If there are three or more wild symbols on the reels, it will trigger the bonus wheel. The bonus wheel has three levels, Silver, Gold, and Diamond. The level is determined by how many wild symbols are on the board to trigger the feature. One nice feature that each time a wild symbol lands on the reels, a tab pops open on the top of the reels to let you know what bonus feature is unlocked.

The multipliers that can be won with the Bonus Wheel are as follows:

  • Silver: 5x, 8x, 18x, 58x, or 80x
  • Gold: 8x, 18, 58x, 98x, or, 588x
  • Diamond: 18x, 58x, 98x,588x, or 1,000x

The silver and diamond wheels also include a space that would move you up to the next level.


Microgaming, along with Just For The Win, developed Deco Diamonds with HTML5, which means that it will work amazingly on any web-based platform. The game has a soundtrack that works well with the Art Deco theme and overall makes for an enjoyable playing experience.
