Spooky Coin: Hold The Spin Slot by Gamzix

Blood-red quilted leather, cobwebs across the corners, and a 666 Wild where every other coin game puts 777. Gamzix dressed their Hold The Spin engine in Halloween skin and gave it a cross-shaped layout - three rows on the outer reels, five on the center. That odd grid shape means 45 pay ways instead of the usual line structure, and the middle reel carries the density. High-pays are carved pumpkins, ghosts with stitched grins, witch hats, and bubbling cauldrons. Low-pays are fruit symbols sewn together like Frankenstein's grocery list - cherries, lemons, plums, oranges with visible thread lines.

Coins land during the base game with random values between 1x and 15x. Any of them can stick around for up to 3 spins, and the counter tracks separately per bet level, so switching stakes doesn't wipe your sticky positions. A Royal Coin on the center reel combined with coins on just two of the three reels fires the Collect feature - the Royal grabs every coin value on the grid and dumps it into your win. Get coins on all three reels instead and you're into the bonus. Three respins, each new coin resets the counter, standard Hold The Spin rules. But the Expand Coins make this version different. They only show up during the bonus and add one extra cell to whichever outer reel they land on, stretching it from 3 rows toward 5. Maximum two expansions per side reel. After expanding, that coin turns into either a 1-15x prize or a Jackpot symbol.

Four fixed jackpots: Mini at 25x, Minor at 50x, Major at 150x, Grand at 1,000x. Only available through Jackpot Coins in the bonus round, so the path to Grand runs through landing enough Expands to open the grid, then hoping those converted positions pull the right tier. There's also a Heap of Coins feature that randomly dumps enough coins to force a bonus trigger - purely luck-based, no way to influence it, and that decorative coin pile above the reels is just set dressing.
