Rainbow Wilds

By Matthew Kennedy | Updated 10 June 2026

Iron Dog Studios is one of those names that is slowly carving out a space for itself in the competitive iGaming industry.It is, therefore, somewhat confusing that while developing a reputation for original and exciting software, that this developer would release Rainbow Wilds, a slot game in the somewhat stale and overused subject of Irish Luck.However, if you thought Iron Dog was just going to release a slot like every other, well, you’re wrong, but probably not by much.

About the slot

Playable from 20p to £100 a spin on all compatible desktop, mobile, and tablet devices, there is no denying this slot looks great, in fact, it may do a better job of bringing the theme to life than any other that has attempted it.That being said, the likes of clovers and horseshoes on the reels make it clear that you’re not dealing with anything particularly new in terms of artwork here, it just happens to be drawn better than most, something we’ve come to expect from Iron Dog.

Gameplay

Rainbow Wilds has a Tumbling Reels features, also known as an Avalanche or Cascading Reels feature, that sees winning combinations disappear to be replaced by other symbols for consecutive wins.These are doubly exciting here, as four or more tumbles and you trigger the free spins feature, with 14 spins for four tumbles. Make your way up to eight consecutive tumble wins, and you will trigger 20 free spins with a 6x multiplier thrown in for good measure.Each successive tumble increases the multiplier, so if the reels land in your favour here, it can lead to some really impressive wins.Rainbow Wilds is not the most unique of slots in terms of content or gameplay, but with a striking design and an excellent free spins game, it certainly commands the attention.
