The age old quest of trying to find an elusive pot of gold at the end of the rainbow is the theme on offer in Rainbow Wilds, a 5 reel, 1,024 ways to win slot from Iron Dog Studio. Played using a tumbling reels game engine, it comes with expanding and sticky wilds as well as a bonus round that awards between 14 and 20 free spins with expanding multipliers. Play on your desktop, tablet or mobile from between 20p and £100 per spin.
The design in many Irish fortune themed slots is often a little crude. You can’t say that about Rainbow Wilds though which looks terrific. The visuals are a little unusual - set against a green, lakeside backdrop, you’ll see various berries rather than the usual playing card values. They’re joined by glasses of stout, harps and hearts as well as gold birds, horse shoes and 4-leaf clovers. 20 times your stake are on offer if you land 5 clovers on adjacent reels.
As well as the standard star wild, you’ll also see expanding and sticky wilds which do exactly what they say on the tin. The sticky wild hits on the middle reel only. The expanding wilds can land anywhere apart from reel 1.
Rainbow Wilds is playing using a tumbling reels game engine - after a winning spin, the successful symbols are removed and the ones above drop down to replace them. These keep on coming as long as a new winning formation is created. Landing 4 or more tumbling reel wins in a row triggers the Free Spins feature - the more successive tumbles, the more free spins on offer:
- 4 tumbles = 14 free spins
- 5 tumbles = 16 free spins
- 6 tumbles = 16 free spins with a starting 3x multiplier
- 7 tumbles = 20 free spins with a starting 3x multiplier
- 8 tumbles = 20 free spins with a starting 6x multiplier
Every successive tumbling reel win boosts a multiplier by 1. Get on a run here and the coins can quickly build.
There’s plenty to like about this updated version of a classic slot theme. For starters, the design is very good. That counts for little if the gameplay doesn’t stack up and by and large it does here. The tumbling reels deliver a steady stream of action and there are opportunities to land a big win in the bonus round.
Get on a roll with the tumbling wins and multipliers in the feature round and the Rainbow Wilds could lead you to that elusive pot of gold – there are wins of 3,000 times your stake available in the feature when you get a 10x multiplier. If you like the theme, there’s plenty to choose from with Yggdrasil Gaming’s Rainbow Ryan a good choice.
