Double Rainbow (Hacksaw Gaming)

Hacksaw Gaming keeps on growing its Pocketz Series, and the newest slot to join this category is Double Rainbow.

It’s a beautifully designed slot with a get mix of colours, and this is my honest review about the slot:

Game Set-Up

It has a 7-column, 6-row game grid that you will use to match symbols in a cluster. When it comes to features, Hacksaw never disappoints and a majority of their slot titles have a lot to offer.

For Double Rainbow, the developer has included quite a number. Among them are the free spins, Cluster Pays, Buy Feature, Cascading Reels, Extra Spins, Increasing Multiplier Reel, and Multiplier Respins.

Betting and Prizes

The game offers a very diverse betting range, and I was allowed to place real money bets between $0.10 to $100 per spin.

What I love most about this slot is the fact that it offers medium volatility but still manages to pay up to 5000xs the stake.

I noticed that depending on the online casino, you can get varying RTPs of between 96.38% and 88.38%.

Double Rainbow Slot Features

Double Rainbow relies on the cluster pays system. As usual with this system, it will trigger a cascade once winning clusters hit.

To form a winning cluster, I needed at least five matching symbols landing either horizontally or vertically.

Hacksaw has used a lot of creativity here, and we also get 7 Rainbow Reels, the same number that is available on a rainbow. Whenever you land a Cloud symbol, it gives you a Reel Multiplier hence activating its reel. Reel Multipliers will be applied to the winning cluster, but only the one with a similar colour to the multiplier is.

Multiplier Clouds are another feature inside the slot. The game offers 2 types of cloud icons. Normal clouds will add multipliers of between x2, x250 to their reel, in addition to a +1 extra spin provided that all those activated reels remain in active mode.

Then there is the Double Rainbow Clouds that add between x2 and x250 multipliers, but award you +3 extra spins for the activated reels that remain active.

If you are lucky to activate the entire 7 reels, you get to trigger the Full Rainbow feature. This way, up to seven reel multipliers will get multiplied by between x2 and x10. Besides, all activated reels that are active get +5 additional spins.

Theme and Design

Double Rainbow seems to borrow from a rainbow theme and this is clear from the colours that the developer has used.

You get several symbols like unicorns, candies, coloured clouds, and rainbows among others.


Double Rainbow may give an impression of a kiddy slot, but once you get deeper into it, you will be amazed by its potential.

It’s a great addition to the popular Pocketz series, and its good payout, coupled with medium volatility makes it a slot suitable for all levels of players.
