Double Rainbow Symbols & Payouts

The symbols

The Double Rainbow online slot has seven reels and six rows. The symbols are made up of different-coloured shapes: red square, orange circle, yellow triangle, green heart, blue star, pink moon, and purple flower. The symbols all carry the same values.

The wild is represented by a lightning bolt. You’ll see other symbols like the Double Rainbow Cloud and the Normal Clous while playing the Double Rainbow slot machine, but more on those in the Game Features section.

Paylines

There are no fixed paylines on the Double Rainbow online slot. To complete a win, you’ll need to form clusters of five or more matching symbols in vertical or horizontal positions. Multiple wins during the same round are added together before being paid out.

Min/max bet, autoplay option

The bet choices of the Double Rainbow slot machine vary between 0.10 and 100.00. If you’re a fan of autoplay, you can choose between 10, 25, 50, 75, 100, 500, or 1,000 consecutive games. To set your loss and win limits, you’ll need to click on the ‘Advanced’ banner. You’ll also be able to set the feature to stop automatically if you hit the special feature. To end the autoplay early, simply click on the stop button that overlays the spin one.

RTP

The Double Rainbow online slot has a standard RTP of 96.38%. This changes to 96.42% when buying 1 Rainbow Spin and to 96.32% when purchasing 4 Rainbow Spins.

Volatility

The Double Rainbow slot machine has medium volatility.

Maximum win

You can win up to 5,000x your stake on the Double Rainbow slot machine. This translates to 500,000 coins when playing with a maximum bet. You won’t find a jackpot feature within the game.

Win up to 500,000 coins on the Double Rainbow online slot

Hacksaw Gaming has given the Double Rainbow slot machine symbols which all pay the same. While I like this feature, I think it takes away from the adrenaline of landing higher paying symbols. However, standard RTP and medium volatility paired with cluster pays give you a good chance of winning, so it’s not that bad. A maximum win of 5,000x may seem low compared to other games, but it can still give you a tasty reward.

Game Features

Wilds 

The Double Rainbow online slot’s wild substitutes for all paying symbols to increase the odds of you completing a cluster.

Cascading Reels

Each cluster triggers the Double Rainbow slot machine’s cascading reels. This is when winning symbols are removed from the reels to make space for new ones to fall. If new clusters are formed, the feature repeats. If none are achieved, the feature ends.

Rainbow Reels

Each reel has a Reel Multiplier that is applied to all wins of its reel colours when a multiplier cloud activates it. The Double Rainbow slot machine has two kinds of multiplier clouds:

  • Normal Cloud: Activates the Reel Multiplier and adds 2x, 3x, 4x, 5x, 10x, 15x, 25x, 50x, 100x, or 250x. You’ll also get one extra spin where all Rainbow Reels remain active.
  • Double Rainbow Cloud: This cloud adds a multiplier of 2x, 3x, 4x, 5x, 10x, 15x, 25x, 50x, 100x, or 250x and rewards three extra spins with active Rainbow Reels.

Full Rainbow

When all seven Rainbow Reels are active, the Double Rainbow online slot rewards the Full Rainbow. All Reel Multipliers are multiplied by 2x, 3x, 4x, 5x, or 10x and you’ll get an additional five spins with all the Rainbow Reels active.

Bonus Buy

You can choose to purchase 1 Rainbow Spin for 100x your stake and 4 Rainbow Spins for 500x your stake through the Buy Bonus button at the bottom of the screen. Remember that the RTP changes to 96.42% and 96.32% respectively when making use of this feature.

Multiply the Double Rainbow slot for big rewards

The Double Rainbow online slot may look simple, but it’s full of surprises. You’ve got the wild in the base game – standard. Then there are the Rainbow Reels – basically each reel has got a multiplier of between 2x and 250x which is triggered by the Multiplier Clouds. Complete the full rainbow for the ultimate prize. I love it – well done Hacksaw Gaming!

Spin over the Double Rainbow slot machine

You’ll find the Double Rainbow online slot’s audiovisuals to have a cute fantasy theme. The brightly-coloured symbols sit on top of a rainbow and are surrounded by clouds and unicorns. As for the music, it’s quite mellow and sweet. A tad childish, but it works.
