At its core, Double Rainbow is a release produced by Hacksaw Gaming, built with crisp artwork and atmosphere. It runs on a straightforward 7 reels layout with a very high volatility profile, and an RTP of 95.82%.
Where Double Rainbow earns its keep is the feature set. Look out for scatter symbols that unlock free spins and extra bonus rounds. The very high volatility means patience is rewarded — expect quiet spells broken by bigger hits. On balance, Double Rainbow is a no-frills option worth a few spins in the demo first.
At 95.82%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
Very high volatility delivers the most extreme payout profile — long dry spells punctuated by potentially massive wins. Only recommended for experienced players with substantial bankrolls and high risk tolerance.
At approximately 1 in 10 spins, wins are infrequent. However, when wins do occur, they tend to be considerably larger to compensate.
Double Rainbow features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
