Double Rainbow Slot Review – Hacksaw Gaming

It has been nearly 3 weeks since my last Hacksaw Gaming slot review, the most recent was for the game titled ‘Bowery Boys’. Which has a max win capped at 10,000x and a massive range of unique features. Today we are learning all about ‘Double Rainbow’, which is available to play now.

Well if you love unicorns, rainbows and sparkles you will love this new slot release. This game shows off a colourful paradise in the clouds, with what looks like the rainbow road from Mario kart and an adorable unicorn character on the left side of the reel set. Symbols are represented by different shapes with one of each colour of the rainbow.

Double Rainbow has a setup of 7 reels by 6 rows, this includes cluster pays of 5 or more matching symbols. This slot is high variance with a set RTP of 96.38% and a max win capped at 5,000x. You can bet from £0.20 – £100.

Double Rainbow Pay Table & Symbols

There are 10 symbols in total, this includes 7 regular symbols. These are represented by red, orange, yellow, green, blue, pink, and purple shapes. In addition to these regular symbols are a normal cloud, a double rainbow cloud, and a wild symbol. The highest paying symbol is any regular symbol, all pay 0.10x – 50x for clusters of 5x -15x. Wilds substitute for all symbols.

Double Rainbow Features

There are 7 rainbow reels, one for each colour of the rainbow. Each rainbow reel has a reel multiplier that applies to all wins of the rainbows reel colour while the reel is active. Reels are activated when a cloud symbol lands, resetting during spins. When a cloud lands on a reel it will reveal a multiplier value and add to the reel multiplier.

The double rainbow cloud will add a multiplier to all active reel multipliers. Possible multipliers are 2x, 3x, 4x, 5x, 10x, 15x, 25x, 50x, 100x or 250x. Also awarding 3 extra spins where all active rainbow reels are active.

When all rainbow reels are activated the ‘Full Rainbow’ feature is triggered. All reel multipliers are multiplied by 2x, 3x, 4x, 5x, or 10x. Also awarding 5 extra spins on all activated rainbow reels.


Overall, I think this slot is such a fun release by the studio and includes a unique reel mechanic. Including a max win capped at 5,000x and multipliers up to 250x. Be sure to try out the game for yourself on release and check out our exclusive casino offers.
