General description

«Rainbow Wilds» doesn't have a gambling feature. Please read about bonus options and special symbols below in the review by


Creators of this video slot have imaged berries, a glass of beer, a harp, a heart, as well as golden pendants in shape of a bird, horse shoe and four-leave clover at the reels. Same icons may follow each other at the reels, but they rarely make long vertical stacks.
Now about different types of Wilds, which replace other symbols:
  1. Wild (a star) drops out at all reels, except the first. It appears more often during Free Tumbles.
  2. Sticky Wild (a pot of gold) shows up only at the third reel. It remains at the screen even if it takes part in combination, but falls down for one cell.
  3. Expanding Wild (W in front of star) can be found at the second-fifth reels. It expands and loads whole reel.
No one of the Wilds brings payoffs on its own.
