The Rainbow Wilds slot game can be found at casinos offering Iron Dog software. Iron Dog are one of the smaller software providers currently on the market, but the appear to be a subsidiary of the far larger and better established 1x2Gaming. They do not offer a full casino platform, but primarily seem to be used as a bolt on package for extra slots games. Iron Dog do publish the Return to Player (RTP)/House Edge information for their slots games within the game paytable. As such we know that the house edge for Rainbow Wilds is 4%.
Rainbow Wilds consists of 5 reels, 4 symbols high with possible 1042 different win ways.
The Golden Clover – The most valuable symbol in the game offering no special features is the “Golden Clover”. Reveal 3 and you will multiply the bet by 50, 4 and you’ll multiply it 150 and 5 “Golden Clover” symbols will multiply the bet by 400.
Wild – The “Star” symbol is Wild, substituting for all symbols other than additional Wild symbols. Wild “Star” symbols only appear on reels 2 to 5.
Sticky Wilds – The “Pot of Gold” symbol is a Wild symbol that sticks in place if it is part of a winning combination after other symbols have gone. It will, however, tumble down if the symbols underneath it disappear. It acts as wild for all symbols, excluding other wilds.
Expanding Wilds – During any spin Wild symbols can randomly expand to fill reels 2,3,4 or 5.
Free Tumbles – Whenever you land a successful Way Win, all the symbols involved will disappear and new symbols will drop down in their place, giving you another chance at winning on a single spin. There is no limit to the number of times this can happen, and wilds will also be active during the feature.
Free Spins – You are awarded free spins based on the number of successive tumbles that you land on a single spin. 4 tumbles in succession will win you 14 free spins. 5 tumbles in succession will win you 16 free spins. 6 tumbles in succession will win you 16 free spins plus a 3x starting multiplier. 7 tumbles in succession will win you 20 free spins plus a 3x starting multiplier. And finally, 8 tumbles in succession will win you 20 free spins plus a 6x starting multiplier. This maximum number of spins you can win is 20 and the largest starting multiplier you can win is 6x.
Rainbow Wilds sees us enter the well-trodden slots world of the leprechaun. We have 4 Leaf Clover symbols and pints of beer, along with golden harp symbols and the leprechauns themselves sitting to either side of the reels. The game looks OK, but there’s nothing here that will blow you away. Wilds have been used to their full capacity, with all sorts going on in the main game, from expanding reels to stickies. Despite the number of wilds on offer there is no bonus round to play, other than the free spins. There are no animated sequences either, which means that Rainbow Wilds has little to offer outside of the main game. The house edge is a fairly average 4%, meaning that there is some value on offer here, but you’ll find better if you shop around.
