Review of Rainbow Riches Cluster Magic Slot

Could the famed luck of the Irish be on your side when you take a spin on the Rainbow Riches Cluster Magic slot online? This classic Irish-themed game presents a 4×4 symbol grid that expands to an 8×8 grid on winning rounds.

To secure a win, you’ll need clusters of five or more matching symbols. Winning symbols disappear in a cascading reels feature, and consecutive cascades unlock a free spins round.

During the bonus round of the Rainbow Riches Cluster Magic slot machine, the gameplay intensifies with the activation of sticky wilds, extra wilds, or win multipliers.

Undertake on a Journey to the Emerald Isle

Many of us are acquainted with the Rainbow Riches series of online and mobile slots, a highly successful range, with this game offering a new twist. Fans of Irish-themed slots games will appreciate the adherence to the classic design seen throughout the series.

The Rainbow Riches Cluster Magic online slot grid is set against lush green fields, adorned with wishing wells, pots of gold, a quaint house, and a vibrant rainbow arcing across the sky. Among the lower-value gems, you’ll find toadstools, lucky clover, and the cheerful leprechaun.

Although offering no direct payouts, the pot of gold and the rainbow serve as wild symbols, substituting for others to create clusters.

A traditional Celtic jig soundtrack ensures that the Rainbow Riches Cluster Magic slot machine couldn’t exude more Irish charm if it tried.

Like other games in the series, this one comes from Barcrest, a UK-based company with a rich history of supplying games to land-based, online, and mobile casinos.

Collect Those Clusters

The betting options range from 0.20 to 50.00 per spin, with Barcrest offering a high average return to player percentage of 96.34%.

Utilizing a cluster pays mechanism, a prize is won by forming clusters of at least five matching symbols connected either horizontally or vertically. The game also features cascading reels, removing winning symbols to allow new ones to drop down and fill the spaces.

The payout depends on the symbols forming the cluster. Refer to the included paytable for detailed information regarding symbols, their values, and potential payouts.

Expand the Grid

While the base games of the Rainbow Riches Cluster Magic slot machine unfold on a 4×4 grid, the real magic triggers upon achieving a win. With the disappearance of winning symbols, the grid expands before new symbols drop down, expanding to a 2-4-6-6-4-2 configuration.

Having an extra symbol in view enhances the likelihood of landing another cluster, leading to continued expansions upon successive wins. After the sixth consecutive win, all 64 spots on the Rainbow Riches Cluster Magic online slot grid become active. Achieving six cascades in a single round also initiates the free spins feature.

During the free spins on the 8×8 grid, a randomly selected modifier remains in play throughout. A bonus wheel spin dictates the modifier received, with the option for a respin if unsatisfied with the outcome.

Wilds remain in place, with two additional wilds added for each cascade in a series, up to a maximum of 12. Landing 12 wilds on the grid of the Rainbow Riches Cluster Magic slot machine triggers an extra four free games. Infinity Spins can be earned, where an escalating multiplier applies to wins during consecutive cascades over eight free games. Each winning spin adds another game to the total, with a cap of 250 spins.

The Wild Rain modifier introduces four to 16 wild symbols in specific patterns on each spin. Reaching six consecutive cascades adds an extra four spins to the total.

Chase the Rainbow

The original Rainbow Riches online slot from Barcrest has been a staple since 2009. This five-reel, 20-line game remains popular due to features like a bonus trail and prize multipliers offered by wishing wells and pots of gold.

Explore the Rainbow Riches Reels of Gold online slot from Barcrest to unveil dual sets of reels, one with three symbol rows and the other colossal reels with 12 rows. Activating several bonuses, such as wild butterflies, stacked wilds, and respins with multipliers, is possible with the assistance of a fairy.
