Soar above fluffy clouds and vibrant rainbows in Double Rainbow, a whimsical cluster pays slot with a cheerful atmosphere. This game plays out on a 7x6 grid where wins occur by landing clusters of 5 or more matching symbols, leading to cascading wins. Cloud symbols introduce reel multipliers that multiply any wins on their respective reels, and filling all reel multipliers activates the Full Rainbow feature for an additional spin with all multipliers active. The Double Rainbow feature triggers if all reel multipliers are filled twice, awarding more free spins and resetting reel multipliers at higher values for extraordinary win potential.
