The six-reel structure includes a horizontal reel above positions 2-5, adding four extra symbol positions. Main reels fluctuate between 2-7 symbols (reels 1 and 6) or 2-6 symbols (reels 2-5), creating the variable ways system. Cascading mechanics trigger after every win—symbols disappear, new ones drop from above (and from the right on the top reel), potentially creating consecutive wins from a single spin.
Bonus Features That Define the Experience
Three distinct mechanics layer together. Cascading Wins activate automatically after any winning combination—symbols vanish, replacements fall, and the process repeats until no new wins form. During base game cascades, payouts accumulate normally without multipliers.
Super Gem Bonus triggers when the Super Gem mystery symbol lands on the horizontal reel. All visible gem symbols (clear diamond, orange, purple, green, and blue gems) instantly transform into a single randomly selected gem type. The Super Gem itself also converts, potentially filling the entire screen with matching high-value symbols before payout calculation.
The main attraction: Free Spins Bonus activates with four or more Pot of Gold scatters. You receive 12 initial spins, plus five additional spins for each scatter beyond the fourth. Here’s where Rainbow Riches Megaways separates from competitors—the win multiplier starts at 1x and increases by 1x after every cascade during free spins. The multiplier never resets between spins, building throughout the entire feature. Land three extra spin symbols (+1, +2, or +3) on the top reel to extend the round. Retriggers are possible by landing four more scatters during the feature.
🎯 Expert Tip: The unlimited multiplier during free spins creates exponential win potential—early cascades establish the multiplier foundation, while later cascades benefit from accumulated multipliers reaching 20x, 50x, or higher.

The clear diamond pays from just two symbols (2x stake), offering more frequent small wins. All other symbols require three matches minimum. Card symbols carry Celtic-themed styling that matches the Irish countryside backdrop.
Buy Features and Bonus Bank System
Three purchase options bypass natural bonus triggers. Buy Pass costs 100x stake for immediate access to 12 free spins with the unlimited multiplier, raising RTP to 96.66%-96.86%.
Take a Chance offers three risk levels: 25% success probability for 25x stake, 50% for 50x stake, or 75% for 75x stake. A wheel spin determines the outcome—success awards 12 free spins, failure loses the stake. This feature maintains 100% RTP across all risk levels.
The Bonus Bank system lets you redirect wins toward Buy Pass cost. Toggle between three modes: Bank Wins Off (normal play), Bank All Wins (every win funds the bonus bank), or Bank Small Wins (wins of 3x stake or less accumulate). Banked funds convert to cash if you exit the game, preventing forfeited value.
💡 Strategy Consideration: The 100% RTP on Take a Chance makes it mathematically neutral—your choice between risk levels depends purely on bankroll management and session length preferences rather than house edge differences.
