Slotmill brings you a little colourful burst today with its latest Irish-themed slot that goes by the name of Rainbow Rush. It's just in time for Paddy's Day, and hopefully, it’ll line your pockets with enough spare change to buy a few pints of stout. Wild symbols can expand to the bottom of the grid and there are some gold ones that can head off in both directions and bring you a multiplier. There are also some free spins hidden away in this little pot of gold.
Full review continued below ↓Lots of Irish-themed slots are making their way to the front of the queue this March with various features and bonuses available. Slotmill seems to be playing it fairly safe with this creation, as wild multipliers and free spins appear to be the order of the day.
The 20 paylines in Rainbow Rush can create basic wins using royals, pictures and wild symbols, with the wilds and leprechauns offering the best value at 20x for a group of five. To be honest, even the royals are fairly well received, as long as a group of four or more drop onto the reels, they should get you a profit.
Regular wild symbols will hand you a payout in their own right, and they'll substitute for the other symbols. Some wild symbols might have an arrow pointing downwards, and these will expand to the bottom of the grid to become a large wild stack. If a gold wild stands on the reels, it will expand upwards and downwards, and also bring you a multiplier.
The free spins bonus requires three scatter symbols to get things going, and while you play for free, you'll have a better chance of seeing those expanded wild symbols. If one of the triggering symbols is a super bonus, then you'll play the upgraded version. This means that any wild that lands will be of the golden variety.
If you'd prefer to go straight to the bonus game, you need to put your hand in your pocket and find 100x to open the door to the feature. For 400x, you can play the super version. There are other options to buy wilds etc., and Burst Mode doesn't require you to watch the game take place, as you can simply see the results instead.
Not all wilds are standard! Some will simply substitute for regular payers, and others will expand downwards to create a stack. However, you might see some golden ones land, and these can expand in both directions and also fetch you a multiplier. The additional boost to your winnings can grow up to 6x.
Three bonus symbols will trigger the standard version of the free spins game and you see the base game mechanic continue. You get a better chance of landing wild symbols, but not much else changes. If one of your triggering symbols is a super bonus, then you are assured of all wild symbols that land being golden. Buying your way into these games is also possible for 100x and 400x.
I like it when a game keeps things simple, but it has to offer some decent potential, and this is done happily through those regular paying symbols. Even the royals can get you a decent return, and there are three types of symbol that can produce the game's 20x top prize for a five-of-a-kind. I witnessed the bonus game come to life a few times as I tested this game, and it didn't seem to be timid or reluctant to show me the bonus features. My wins during the bonus rounds were fairly substantial and always over 40x.
The birds are singing, the sky is blue, and everything feels distinctly happy. There doesn't seem to be much attention paid to the rainbow aspect, but it does make an appearance on the wild symbols. As you spin these reels, you can listen to some traditional Irish music that helps lift the mood, even if the wins aren't living up to expectations. It looks good on mobile phones, and that's great news if you like to play while on the move.
Rainbow Rush is a fairly typical slot, but it does stand out slightly from the rest, thanks to its expanding wild symbols that do their best to bring you big wins and mix up the gameplay a little. It doesn't take long to work out what's happening, and there's nothing here to baffle you in any way. It's great for newbies, and even those with a bit more experience will probably find a few moments here to enjoy.
