Do You Have the Luck of the Irish?

The luck of the Irish is a very popular slot theme, which isn’t too surprising. After all, when it comes to free online slots, a bit of luck is always useful! The game is filled with Irish-themed graphics and symbols that include lucky charm necklaces, four-leaf clovers, Celtic patterns, a pot of gold, a green top hat and a green concertina. Of course, not all symbols are made equally - and the ones you will want to look out for are the wild, which is represented by a leprechaun, and a scatter that is represented by a rainbow.

The wild can be used to replace all of the other symbols on the reels (other than the scatter), and the scatter will trigger payouts if there are at least two of them on the reels. This is a really easy way to boost your winnings, so it is definitely worth keeping an eye out for the scatter! The other symbols in the game will also pay out cash prizes if there are two or more of them on one payline, and you can decide how many paylines you want to work with. You can also use between one and ten paylines, so you can either be a big spender and use all lines or you can go for as low as 1p per spin.

Bonus Feature

Merkur's Under The Rainbow comes with a bonus feature that can be triggered by the scatter symbol - simply get two matching symbols on an active payline to win ten free spins. This feature isn’t particularly life-changing or exciting, but it can be a useful way to boost your winnings. There are also two double gamble features that you can use to gamble your winnings for a chance at an even bigger prize. The first feature is a fairly basic card feature that most players will recognise, while the second feature offers a range of different prizes that you can hedge your bets with.


Overall, Under The Rainbow is a perfectly enjoyable game with a few good features and enjoyable graphics. The Irish theme is pretty generic, but that isn’t to say it is a bad theme at all - and the gameplay itself is fluid and enjoyable, if a little basic. It may not be a particularly original slots game, but it is still a lot of fun. And if you like a good jackpot, that may tempt you to play. Under The Rainbow can be played on desktop, mobile and tablet devices, so you can play it on your preferred device at any time you want.
