What Is the Double Rainbow Slot?
Double Rainbow is part of Hacksaw Gaming’s “Pocketz” series—slots designed for vibrant mobile play and quick, rewarding action. Released on 9 March 2022, this 7-reel, 6-row cluster slot trades traditional paylines for a more engaging “cluster pays” mechanic.
Double Rainbow is a prime example of Hacksaw's commitment to innovative and mobile-friendly designs. To score a win, you’ll need at least five matching candy symbols connected horizontally or vertically.
The game’s standout feature is its Rainbow Reels—seven in total—each capable of collecting reel multipliers that can lead to massive payout potential. With a maximum win of 5,000x your bet, this isn’t just a cute slot; it’s one that can deliver serious excitement.

The slot uses a cluster pays system. When a winning cluster forms, the cascades feature is triggered. To form a winning cluster, a minimum of 5 matching symbols must land in adjacent horizontal or vertical blocks. These candy-like symbols replace the regular pay symbols, which all have equal value. Clusters of five symbols pay 0.1x your bet, while clusters of 15 or more can bring in 50x your bet.

The Red Square Candy, Orange Circle Candy, Yellow Triangle Candy, Green Heart-shaped candy, Blue Star Candy, Pink Moon Candy, and Purple Crown Candy symbols are the games low paying symbols. Below is the paytable for these icons based on the maximum wager placed.

Special Symbol
The Thunderbolt with the word wild on it is the game's wild symbol. This icon can replace all other symbols on the reels.
Cloud Symbol
The real magic begins when Cloud Symbols appear. When a cloud symbol lands on a reel, it activates the corresponding rainbow-coloured reel multiplier, giving that reel a multiplier boost. The normal cloud symbols also add a multiplier of anything between 2x and 250x, plus one additional spin. Furthermore, Normal Clouds also ensure that all currently activated rainbow reels remain active during the free spin, enhancing the potential for consecutive wins.
Double Rainbow Cloud Symbol
The Cloud with Two Rainbows represents the game's Double Rainbow Cloud icon. This icon gives you an additional spin, whereby all activated Rainbow Reels stay open. Furthermore, it offers multipliers ranging from 2x to 250x.
Full Rainbow Feature
Activate all seven reels, and you’ll unlock the Full Rainbow feature. Here, every reel multiplier is multiplied again by x2–x10, plus you get +5 extra spins. When the Full Rainbow feature is activated, all individual reel multipliers are further multiplied by an additional factor of 2x, 3x, 4x, 5x, or 10x, creating the potential for massive payouts.
Bonus Buy Feature
For players who want to skip the base grind, Double Rainbow includes two options for the bonus buy feature:
- 1 Rainbow Spin (10x bet) – Guarantees one spin with three active reels and multipliers starting at x4.
- 4 Rainbow Spins (50x bet) – Guarantees four spins with the same setup but more extended potential.
These Rainbow Spins add extra thrill for players who prefer to jump straight into the colorful chaos.
