Double Rainbow stands out with its innovative blend of cluster pays, cascading reels, and a vibrant multiplier system tied to seven rainbow-colored reels. These features create a dynamic gameplay experience where every spin can trigger expanding multipliers and free spins, rewarding players with potentially big wins. The combination of normal and double rainbow multiplier clouds, along with the coveted Full Rainbow feature, adds layers of excitement and strategic anticipation, making this slot both visually captivating and richly rewarding.
Double Rainbow features seven reels, each assigned one of the seven colors of the rainbow. When a cloud symbol lands on a reel, it activates that reel’s multiplier, which applies to any winning clusters matching the reel’s color. These multipliers reset at the start of each new spin, creating a fresh opportunity to build powerful combinations. The color-coded reels add a unique twist to the cluster pay mechanic, encouraging players to watch for specific reel activations and multiplier boosts, which can significantly enhance payouts during cascades.
There are two types of multiplier clouds in the game: Normal Clouds and Double Rainbow Clouds. Normal Clouds add a random multiplier-ranging from 2x up to 250x-to the reel’s multiplier and grant one free spin with all currently activated rainbow reels remaining active. Double Rainbow Clouds are even more rewarding, adding their multiplier value to all active reels simultaneously and awarding three free spins. These clouds are key to unlocking bigger multipliers and extending gameplay, making each spin potentially more lucrative as multipliers stack and spins accumulate.
The Full Rainbow feature triggers when all seven reels are activated with multipliers. At this point, all individual reel multipliers are multiplied by an additional factor of 2x, 3x, 4x, 5x, or 10x, dramatically increasing the potential payout. Alongside this multiplier boost, players receive five free spins where all rainbow reels remain active, maximizing the chances of hitting massive cluster wins. This feature represents the pinnacle of the slot’s multiplier mechanics, rewarding persistence and luck with some of the largest possible wins.
The wild in Double Rainbow is a lightning bolt that substitutes for all standard symbols, helping to complete winning clusters. This symbol increases the frequency of wins by filling gaps in clusters, which is especially valuable given the cluster pays system. While it does not have a multiplier itself, its ability to create more winning combinations synergizes well with the rainbow reel multipliers, enhancing overall win potential during both base and bonus rounds.
Double Rainbow employs cascading reels, meaning that when a winning cluster forms, the winning symbols disappear and are replaced by new symbols falling from above. This can create consecutive wins from a single spin, especially when combined with active reel multipliers. Cascades continue until no new winning clusters appear, offering extended play and the chance to build multiplier values progressively, which keeps the gameplay engaging and rewarding.
For players who prefer to jump straight into the action, Double Rainbow offers a bonus buy feature with two options. The first option costs 10x the bet and guarantees one Rainbow Spin with three activated reels starting at a 4x multiplier and at least one free spin. The second, more expensive option costs 50x the bet and guarantees four Rainbow Spins with the same starting conditions but more free spins. This feature allows players to bypass the base game grind and access the slot’s exciting multiplier mechanics and free spins directly, appealing to those who want immediate high-volatility gameplay.
