Find The Treasure With Rainbow Gold
UK developer IronDog has slowly been building their slot empire. They recent got a leg up by moving onto the Quickfire software platform and signing a content deal with Video Slots Casino. Their latest slot release is called Rainbow Gold and should make them a household name if fans pick it up.
The graphical style used here gives it a similar look and feel to slots like Finn and the Swirly Spin from NetEnt and Leprechaun Hills from Quickspin, where the reels spin against a natural background of hills and lush forests while a magical leprechaun joins you on the screen. Often times it feels like you are playing a premium mobile game when you are spinning the reels here.
IronDog have certainly locked onto a great look that should endear them with many slot fans who aren’t familiar with their output. The 96% RTP used here is just about spot on. Instead of paylines we see IronDog use a 1024 ways to win system which works perfectly on the slot’s large 5×4 reels.
Free Spins And Free Tumbles
The main bonus feature used in Rainbow Gold is a two tiered system. The Tumbles feature is the foundation here. It is feature where each time a winning combination forms, the matched icons disappear and the icons above the formed gap drop down to potentially make another combination.
These Tumbles can occur multiple times in a row and this is how you access the free games feature. When you register at least 4 consecutive Tumbles in a row, you will instantly win 14 free spins. You can keep getting better features added to the free spins the more consecutive Tumbles triggered the feature. With 8 consecutively triggered Tumbles you can win 20 free spins that also include an active 6x win multiplier for the duration of the spins.
The Special Wild Trio
Rainbow Gold features 3 wild symbols that can appear on the reels. The basic wild is a star shaped icon and it will show up as a substitute icon on reel 2 to 5. They can show up more often during Tumbles.
Sticky Wilds only appear on reel 3 and when they land on the reels as part of a winning combination, they will remain in place after the Tumbles feature clears the winning icons, potentially granting you another wild win. Finally there are the expanding wilds represented by a colourful W icon. When they land they can expand across the whole reel area. They also show up more often after Tumbles.
