📖 Detailed Explanation
In the Sticky Coin: Hold the Spin slot's Hold and Spin bonus game, several types of special coins appear to enhance winning potential.
The bonus triggers when at least one coin lands on each of the three reels, awarding initial spins that reset with new coins. Only coin symbols spin during this feature, including:
- Royal Coins: Appear exclusively on the middle reel and collect values from all other coins on the screen, such as Sticky Coins, Expand Coins, and Jackpot Coins. The total is added to the bonus win at the end.
- Expand Coins: Land only in the bonus and add an extra row (up to two on reels 1 and 3, max 5 rows total). They then award a random prize from 1x to 15x the bet or transform into a Jackpot Coin, increasing win ways.
- Jackpot Coins: Award one of four fixed jackpots—Mini (25x bet), Minor (50x), Major (150x), or Grand (1,000x)—adding jackpot excitement.
- Prize Coins: Standard coins with values from 1x to 15x the bet that stick and accumulate toward the total win.
- Sticky Coins: Can persist from the base game or appear anew, staying for 1-3 spins to help fill the grid.
These coins create dynamic gameplay, with Royal Coins gathering values, Expand Coins growing the grid, and Jackpots offering massive payouts up to the 5,000x max win. The round ends after three spins without new coins or when the grid fills.
