How Double Rainbow works

Every week in the online casino world, new slot machines are offered to the gaming community. The various providers use their imagination to come up with themes that have, in some cases, never been used before. In this review, we will introduce you to Double Rainbow. This slot is a creation of Hacksaw Gaming and was released in March 2022.

The main theme of this slot machine revolves around rainbows... and unicorns. A theme that is not often used in the online casino world and that's why this creation is so talked about.

A 7-column starting grid with 6 symbols inside awaits you in Double Rainbow. The graphics of this slot machine are quite nice and the musical atmosphere is quite catchy.

Double Rainbow is a slot machine that doesn't have a bonus feature to speak of, but you will still be able to unlock a feature during your pay spins.

However, even though these are not bonus games as we know them in the online casino world, we decided to present this feature in the part where we talk about the bonus.

Connections on this slot machine work in a cascading fashion, which means that a game round only stops when no more connections are possible on that round. When a connection occurs, the connecting symbols disappear from the starting grid and are replaced by new symbols.

Double Rainbow is a free slot machine to try at Lucky7Bonus. On this slot, you will be able to play between €0.10 and €100 per game spin. However, depending on the platform you go to, the stakes may change.

The different symbols of Double Rainbow

Double Rainbow by Hacksaw Gaming is a slot machine that features several different symbols. First of all, you have a wild symbol, represented by a lightning bolt with "wild" written in a rainbow on it. This symbol allows you to connect with all the other symbols in the slot, except the one that allows you to have the feature.

Thus, the Double Rainbow wild symbol has no value, it just takes the value of the symbols it connects with.

It's very rare in the online casino world, but Double Rainbow is a slot machine where there is no payout difference. All the symbols on this slot have the same value. In total, there are 7 different symbols in this slot and they are represented by candies of different sizes.

The colors, meanwhile, represent all those of a rainbow. The following two screenshots show the values of each symbol in the Double Rainbow slot. The values shown are for a starting bet of 1 euro.

The different connections of Double Rainbow

Double Rainbow's starting grid is not the most common in the online casino world. So, with its cascading connections, Hacksaw Gaming has decided to implement cluster connections for this slot.

That is, for a connection to occur, at least 5 of the same symbols must touch each other from top to bottom and/or from left to right. The more common symbols you have in a cluster, the bigger the cluster will be and the bigger your final win will be.

For those who do not understand how clustered connections work, the following screen explains it perfectly. In the top starting grid, you have the example of a connection that works with clusters.

The starting grid at the bottom shows a connection that does not work.

How the Double Rainbow bonus works

As explained in the introduction of this slot machine, there are no bonus features as they are usually known in the slot game world. However, it will still be possible to unlock free spins on this slot.

So, every time a sun symbol with a cloud appears on a column, it will color the column. When it first appears on your screen, it will give you four free spins and also appear with a multiplier.

Different multiplier values can appear: x 2, x 3, x 4, x 5, x 10, x 15, x 20, x 25, x 50, x 100, x 250. Each time a new cloud will appear, it will give you 1 extra free spin.

It will also be possible to get a double rainbow. This symbol multiplies the value of the column in which it appears. So, if it appears in a column where a multiplier x 10 is already present, it will multiply the value of the latter.

The multipliers that can be given are: x 2, x 3, x 4, x 5 and x 10. Just like the other symbol, each time this symbol appears, it will give you extra free spins. There are three of these.

Finally, one last thing to know during these bonus games, if you manage to get all the columns lit, then you will see all your multipliers multiplied by x 10. In addition, the slot will give you 5 extra free spins.

It is very important to understand how the connections work during these free games. Every time a cloud appears on a column, it will give you a new color. Only the color that connects and is already revealed allows you to see your win multiplied.

To understand, we will give you an example. In the following screen, you can see that the orange color has been revealed. So you can also see that it is part of a connection. This gain will be multiplied by the value displayed in its column, i.e. x 4. Also, no matter where in the column the connection takes place, your win will still be multiplied if the color has been revealed.

For example, the orange connection in the previous screen takes place in the orange column. However, if this connection takes place somewhere else than in the orange column, your win will still be multiplied, since the orange color is already revealed.

Another example is if you connect the purple symbol, which is not revealed, then your win will not have a multiplier. Another thing to know is that if your purple connection is in a column where a multiplier is already present, then your win will not be multiplied.

It will be possible for you to access the kind of free games present on Double Rainbow, but once again, these don't work as we are used to.

You have two choices.

  • The first one will cost you 10 times your starting bet and will give you the right to 1 free spin guaranteed with 3 colored reels in x 4. So what will change is not that you will activate the bonus, but that each spin will now cost you 10 euros.

  • The second one will cost you 50 times your starting bet, give you the right to 4 free spins with at least 3 colored reels in x 4. Just like the other one, this option will increase your game spin from 1 euro to 50 euros.

Our opinion on Double Rainbow

Our opinion on Double Rainbow is quite positive. First of all, we must underline the magnificent graphics that are present on this slot. These will allow you to travel in the middle of the unicorns' world and its childish universe. Something very rare to be underlined, but the animations are also of very beautiful quality.

While playing this slot, it may be hard to see how much volatility this slot has. However, once you start getting a lot of clouds on a single spin and high multipliers, then you understand what Double Rainbow is capable of.

When you play this slot, you can win up to 5,000 times your original bet. Even though Double Rainbow is a fun slot to play, it can get boring quickly, as it lacks a bonus feature or in the base game.

Another small negative point of Double Rainbow is its theoretical return to the player. On the vast majority of slot machines that are present in the online casino world, it is around 96%. Unexpectedly, on Double Rainbow, the RTP is 94.4%, which places this slot in the low average.

In spite of a few shortcomings, Double Rainbow remains an excellent achievement from Hacksaw Gaming where you can get the maximum win on any round of the game.
