Double Rainbow

Unicorns are pretty cute to start with but Hacksaw gaming have dialed the cute up to 173 making my little pony look like a bunch of grouches in this rainbow chase of a slot. You can take home as much as 5,000 times your stake while playing the 7 by 6 reels on this particular offering. Be sure to make ample use of the free spins and the multipliers when you see the clouds moving in.

How to Play

Perhaps it’s time to start a new genre of slots and call them Rainbow Casino Slots because it seems that Hacksaw gaming are onto something. That Unicorn in the corner certainly knows something we don’t. How else would you explain that expression? Stakes can be set in the 0.20 to 100 range. There is also an option to buy rainbow respins (more about that later) as well as setting the autospin to as many as 1,000 spins without you having to lift a finger.

Double Rainbow Gameplay & Features

There are plenty of options for winning combination on this slot. Lots of colourful symbols to match up. In total there are 7 different symbols. You need to group at least 5 to win although the payback in that case will be rather low. Because of the size of the grid you can match up quite a lot and should you match as many as 15 of the same symbol you could win as much 50 times your stake.

Each time you land a winning combination, the winning symbols disappear and new ones cascade into place. This can set off a chain reaction of wins without you having to spin the reels much.

You’ll want to look out for clouds because they are what make rainbows. When you land a cloud, the rainbow colour of that reel lights up and gains a multiplier as well as a free spin. If you land a cloud somewhere else, you will gain another free spin. If you land a cloud in a reel that is already lit, then the multiplier simply increases. Besides the regular cloud symbol there is also a double cloud symbol that will both turn on the rainbow colour in its reel as well as increase the multiplier in all of the other lit rainbow coloured reels.

Should you manage to turn on the bright rainbow colours in all of the reels that little unicorn will probably not know what to do with itself out of sheer pleasure. On top of that all of the multipliers will increase by between 2x and 10x and you will get another 5 free spins.

Double Rainbow RTP & Volatility

Double Rainbow has a Return to Player rate of 96.38% and Medium Volatility.

Double Rainbow Verdict

If you are looking for something lighthearted with plenty of action then Double Rainbow is probably right what you after. Even though you will stay with more or less the same screen, the rainbow multipliers and the cascading effect ensure that there is almost always something going on.
