Play Under the Rainbow for Free

Under the Rainbow is the latest in a long line of slot machines which look to the Emerald Isle for inspiration. Let's face it, nothing quite gets you in the mood for some spins of a slot machine than a game that is filled up with luck-bringing charms and other titbits related to the Irish folklore and legend. As such, players can expect to come across some iconic symbols, including four-leaf clovers, lucky charm necklaces with Celtic-style patterns, green top hats, an emerald green concertina, and a glowing pot full of gold.

As legend has it, there will always be a pot of gold waiting at the end of every rainbow. Well, punters might also be able to find their own small fortunes thanks to two special icons in this slot machine – the rainbow scatter and the wild leprechaun. Both of these symbols are bestowed with some helpful gameplay characteristics to give players that little bit of bonus boost.

For a start, the leprechaun character is a wild symbol that will substitute for all other game symbols whenever there is a chance to create a winning line (expect for the scatter). The scattered rainbow, on the other hand, will pay wins whenever two or more appear in any position on the reels.

Besides from the scatter symbol, all other icons pay their wins when two or more appear on an active payline. The number of paylines that are placed can be chosen by the player by simply toggling the options in the control panel. Spinners can play with 1, 3, 5, 7 or 10 paylines with the following bets staked on each active line: 0.01, 0.02, 0.05, 0.10, 0.20, 0.50, 1.00 and 2.00 credits. So, players can go all out for a total maximum bet of 20 credits while it is just as possible to play with wagers as little as 0.01 per spin.

Whenever a successful sequence is hit, a line bet multiplier will be applied to the value of the bet on the payline in question. You can see all of those potential wins in the paytable below:

The rainbow coloured scatter symbol awards total bet wins of 20x, 50x, 100x and 500x whenever two or more appear on the reels regardless of payline position. But not only that, this icon will also award a round of 10 free spins should three or more show up. This bonus feature is fairly straightforward in the grand scheme of video slot machines, with no mind-blowing special features other than the fact that extra wild leprechauns may be placed on the reels for more chances to complete winning combinations.

If you aren't entirely satisfied with your wins from any spin, then you may be able to gamble your prize for even bigger winnings. There are actually two different gamble side games available in this Merkur Gaming slot machine, the first of which is a simple card gamble in which punters have to correctly guess the colour of a playing card to double their winnings. The other gamble game is a little bit more interesting, presenting a ladder of different prizes in which punters may rise or fall, offering a degree of insurance in case the gamble is unsuccessful.

As far as Irish themed slot machines go, Under the Rainbow is a perfectly satisfactory effort by Merkur Gaming. The reels are suitably pleasant to look at with symbols that are designed with some simple 3D animations, while there are also some free spins and a gamble options to keep things reasonably interesting. Although, having said that, there isn't anything particularly mind-blowing to set this slot machine apart from the many other lucky Irish gambling games out there.
