Discover one of the latest slot machines from casino software provider Hacksaw Gaming: Double Rainbow. Online for around 1 year, this slot machine focuses on a theme that has been little exploited by casino game developers, that of children’s games and fantasy. The slot machine’s childlike appearance and theme do not make it an extremely popular game with players. However, Double Rainbow has a very interesting cascade feature which, combined with multipliers, offers a real chance of winning.

In this article, we’ll take a look at the game’s cascading system and the various bonus features that characterise this slot machine.

The world of Double Rainbow slot

The world of Double Rainbow picks up on the theme and elements of early childhood, with rainbows, clouds and unicorns. The gamble taken by developer Hacksaw Gaming is a risky one, as casino players are adults and therefore not very attracted to this kind of theme. However, with this slot machine, the publisher is extending its range and offering casino games for all tastes.

The graphics are very well done, with very girly pastel colours, and the symbols are sweets in different colours. The game is punctuated by visual animations and sound effects to provide an immersive and relaxing gaming experience.

How does the Double Rainbow slot machine work ?

The Double Rainbow game is characterised by a cascading action that differs slightly from the mechanism of more classic machines of Hacksaw gaming slots such as Chaos Crew slot. The grid has 7 reels and 6 rows, with the cascade configuration the reels don’t spin to generate symbols, but symbols fall from the top to the bottom to fill the spaces.

When the player forms a winning combination in a cluster, the symbols involved disappear and new ones replace the empty spaces. If new winning combinations are formed after the replacement, the process of disappearance and replacement is repeated. This can result in a series of successive cascades of paying connections that is not limited in number. 

The cascade feature adds a dynamic and exciting dimension to the gameplay by offering more chances to win in a single round. The cascades stop when it is no longer possible to form winning combinations with those on the grid.

To play and start receiving your first winnings, you need to place a bet of at least 20 cents up to a maximum of €100. Once you have set your bet, simply click on the arrow on the left to start the game.

Double Rainbow symbols

The Double Rainbow paying symbols take the form of sweets, of which there are 7, like the 7 colours of the rainbow. So you’ll get a blue star-shaped candy, an orange one, a red one, a purple tulip-shaped candy, a green heart-shaped candy, a pink moon-shaped candy and a yellow triangular candy. It also has a Wild symbol that replaces certain symbols to form winning combinations.

The special feature of Double Rainbow’s gameplay is the payout. Hacksaw Gaming has made the original choice that all symbols pay out in the same way. The winnings are calculated according to the number of symbols that make up the combination. The more signs there are, the higher the payout.

Possible connections at Double Rainbow

Connections on Double Rainbow are formed in clusters and not on a fixed payline. To make a winning combination, the player must get at least 5 identical symbols touching to receive 1x his bet, so he can make clusters of up to 15 elements that will pay 50 times the starting bet.

The symbol cluster can be located anywhere on the grid and can be vertical or horizontal. Once the combination has been paid, the symbols that make it up disappear and the cascades start to form new ones.

How the Double Rainbow bonus is triggered and how it works ?

Once again, Double Rainbow stands out with a bonus feature that takes the form of multipliers rather than free spins. Bonus features are activated according to the bonuses obtained on the grid. During the free spins, the winning combinations are formed differently: a colour is given and only symbols of that colour will be paid. The winning colour changes each time a new bonus symbol appears.

Each reel has a multiplier that is activated when the bonus symbols appear. You will therefore have 2 bonus features: 

  • Multiplier Clouds

This single cloud symbol will activate the associated multiplier on the reel where it appears, then randomly add x2, x3, x4, x5, x10, x15, x25, x50, x100 or x250 to it. The rainbow cloud symbol will offer a free spin and add a multiplier on all active reels in the grid and 3 extra spins.

  • Full Rainbow

If during your game session you manage to activate all 7 reels then you trigger the “Full Rainbow” feature. In this configuration, you’ll see all your reel multipliers multiplied by x2, x3, x4, x5, x10 and you’ll get 5 extra free spins.

The game allows you to buy these bonuses to get them faster, with 2 different packages. The first package costs x10 for 1 free spin with 3 activated reels and an associated x4 multiplier. A second package offers the same content but on 4 spins for 50 times the initial stake.

This bonus feature offers a maximum win of x5,000.
