📖 Detailed Explanation
The Expand Coin is an exclusive feature in the Sticky Coin: Hold the Spin slot's bonus round (Hold and Spin), where it adds extra rows to specific reels to boost winning potential.
Landing an Expand Coin, marked by an up arrow, during the bonus expands the reel it lands on. It adds one extra position, with reels 1 and 3 able to grow by up to two additional rows (increasing them to a maximum of 5 rows total). This expansion creates more spots for coins, enhancing chances to fill the grid and trigger jackpots or larger payouts.
After expanding, the Expand Coin awards a random prize between 1x and 15x the bet or transforms into a Jackpot Coin. The bonus round, triggered by at least one coin on each of the three reels, gives initial respins (typically 3) that reset with new coins; only coin symbols (including Expand, Royal, and Jackpot) appear.
- Expands reels 1 and 3 by up to 2 rows for more coin positions.
- Pays 1x-15x bet or upgrades to Jackpot Coin post-expansion.
- Increases grid-filling potential, aiding max 5000x win.
- Available only in Hold and Spin bonus, not base game.
This mechanic adds thrill, as seen in player examples where an Expand Coin extends the bonus on a near-full grid, potentially securing a Grand Jackpot. Combined with Sticky Coins (1-3 spins) and Royal Coins (collect values), it elevates the Hold and Spin experience in this 3-5-3 Gamzix slot with 45 ways.
