Quick Facts

Facts verified July 2026 against the live Chips.gg game configuration.

Game Features and Bonuses

• Layout and Cluster Pays: The game is played on a 7x6 grid. Wins are formed by landing clusters of 5 or more matching symbols, which then disappear, allowing new symbols to cascade down and potentially create further wins.

• Wild Symbol: A lightning bolt symbol acts as the Wild, substituting for other paying symbols to help form winning clusters.

• Rainbow Reels: Each of the 7 reels has an associated multiplier. These multipliers are activated by landing cloud symbols on their respective reels and apply to wins on that reel's color. Activated multipliers reset after each spin.

• Multiplier Clouds: There are two types of cloud symbols: Normal Clouds and Double Rainbow Clouds. Normal Clouds add a multiplier value (up to 250x) to their reel and grant 1 extra spin. Double Rainbow Clouds add their multiplier value (up to 250x) to all active reel multipliers and award 3 extra spins.

• Full Rainbow Feature: Activating all rainbow reels simultaneously triggers the Full Rainbow feature. This applies an additional multiplier (2x, 3x, 4x, 5x, or 10x) to all active reel multipliers and grants 5 extra spins.

Gameplay Mechanics and Strategies

• Unique Mechanics: Double Rainbow utilizes a cluster pays system combined with cascading wins, where winning symbols are removed and replaced. The core mechanic revolves around activating and building multipliers on individual Rainbow Reels through cloud symbols, which can then be boosted further by Double Rainbow Clouds and the Full Rainbow feature.

• In-Game Dynamics: The game's dynamics are driven by the accumulation of reel multipliers. Landing cloud symbols is key to increasing potential payouts, as these multipliers can significantly enhance cluster wins. The extra spins awarded by cloud symbols extend the bonus potential within a single round.

• Player Strategy: While no strategy can alter the game's inherent RTP, players might consider their betting strategy in relation to the game's medium volatility. Managing bankroll to sustain play through periods without frequent cloud symbol activations could be a consideration, aiming for the higher multiplier potential offered by the Full Rainbow feature.

Comparison with Similar Slots

Double Rainbow shares thematic and mechanical similarities with other grid slots. Hacksaw Gaming's own Harvest Wilds also features a grid layout with persistent multipliers that can grow. Another comparable title is Jammin' Jars 2 by Push Gaming, which uses a cluster pays system with cascading wins and increasing multipliers, though its focus is on roaming Wilds rather than reel-specific multipliers. Sweet Bonanza by Pragmatic Play is another grid slot with cascading wins and multipliers, but it relies on scatter symbols for its bonus rounds rather than the reel activation seen here.
