Reels, Paylines, or Grid Mechanics
Double Rainbow employs a 5×4 grid layout where players can adjust their bet up to five coins per line across thirty-five active paylines. This flexibility caters to different player preferences while providing ample opportunities for matching symbols to form winning combinations.
Wins are calculated by landing three or more identical symbols starting from the first reel, with each consecutive match on adjacent reels adding value to the payout. The game features four progressive jackpots, triggered randomly when five of a kind wins land in any position across all five reels. A unique feature known as ‘Double Up’ is available for triggering this jackpot win by doubling any standard or scatter symbol.
Core Gameplay Mechanics and Flow
Gameplay begins with players choosing their preferred betting range from 0.01 to 5 credits per line, while the option of up to ten bet levels offers a comprehensive experience catering to various player budgets. A unique feature called ‘Rainbow Bet’ allows for wagering on any specific position across all five reels, ensuring consistent wins.
Double Rainbow slot utilizes an innovative ‘Free Wheel Spin’ mechanic where players can unlock free spins by achieving three or more rainbow wild symbols within the first two rounds of play. Once triggered, these symbols begin to accumulate and transform into wilds at random intervals during subsequent plays.
Wild Symbols, Scatter Symbols, and Special Icons
Double Rainbow incorporates a unique ‘Rainbow Wild’ symbol that becomes active after triggering its feature with scatter symbols placed on reels 1 through 3 or when three consecutive rainbow wilds land in any position across all five reels. This symbol acts as both a multiplier (x2) and a free spin trigger.
Players can also win up to fifteen additional spins for matching combinations of double rainbow icons within the main game, boosting their potential payout opportunities significantly with each activation.
Bonus Features and Bonus Rounds
Double Rainbow is rich in exciting bonus rounds offering varied levels of risk versus reward. One such feature is ‘Rainbow Double’, activated by landing at least one rainbow wild symbol during regular spins or when the ‘Free Wheel Spin’ condition triggers five consecutive rainbows across reels 1 to 5, respectively.
In these bonus games, up to ten free spins can be gained for every three of a kind won that meets specific requirements (three red diamonds and two yellow topaz wins). Double Rainbow’s diverse array of potential winning combinations provides an excellent opportunity to maximize profits with the correct strategy application during regular play or when participating in available bonuses.
Free Spins Mechanics and Variations
Double Rainbow’s progressive jackpots offer four distinct categories – Mini, Minor, Major, and Mega Jackpot – triggered by five of a kind wins that fulfill specific criteria for each level. A separate jackpot meter tracks accumulation towards these levels as players wager and engage with the game regularly.
Upon completing one round within Double Rainbow gameplay sessions lasting under an hour or accumulating ten accumulated bonus credits over multiple rounds completed between hours, all earned bonus cash amounts can be exchanged at any given time during ongoing session progress without forfeiting current active winnings.
