📖 Detailed Explanation
In the Sticky Coin: Hold the Spin slot's bonus round (Hold and Spin feature), the Royal Coin appears exclusively on the middle reel (reel 2) and acts as a collector, gathering the values of all other coin symbols visible on the screen.
This bonus round triggers when at least one coin lands on each of the three reels, awarding initial respins (typically 3) that reset with new coins. Only coin symbols appear, including regular prize coins (1x-15x bet), Expand Coins, Jackpot Coins, and Royal Coins. The Royal Coin locks in place, collecting values from coins on reels 1 and 3, Sticky Coins, Expand Coins, and Jackpot Coins. These values accumulate and contribute to the total bonus win at the end of the feature.
- Collection Process: Royal Coins store values from surrounding coins, which may pay out and vanish to make room for more, keeping the grid dynamic.
- Enhancements: Some sources note modifiers like Royal Collect, Booster, or Doubler on Royal Coins for extra boosts; it gathers repeatedly as new coins land.
- End Trigger: The round ends after 3 consecutive empty respins or when the grid fills/max payout (5000x bet) is reached.
- Win Potential: Combined with Jackpot Coins (Mini 25x to Grand 1000x bet) and Expand Coins (adding reel positions), Royal Coins enable massive payouts.
Sources consistently describe this mechanic across reviews, emphasizing its role in stacking wins efficiently during the high-volatility bonus.
