Key Details:

• Hit Frequency: 33.33%​

The symbols include lower-paying card suits (clubs, diamonds, hearts, spades) and higher-paying thematic icons like necklaces, potion bottles, skulls, and treasure chests. The Serpent Wild symbol plays a central role in the game’s features.

• Gold Coins & Progress Bar: Gold Coins may randomly appear on symbols, provided there are Serpent Wild upgrades yet to be unlocked. Collecting these coins fills the Serpent Wild progress bar:​
  • 30 Gold Coins: Unlocks Upgrade 1
  • 60 Gold Coins: Unlocks Upgrade 2​
  • 90 Gold Coins: Unlocks Upgrade 3​

Once all upgrades are unlocked, the progress bar transforms into a sixth reel, which does not contain any card suit symbols.

• ​Serpent Wild Upgrades:

  • Upgrade 1: Transforms the Serpent Wild into a 1×4 Super symbol.

  • Upgrade 2: Adds a random multiplier (x2, x3, or x5) to the Serpent Wild.​
  • Upgrade 3: Turns the Serpent Wild into a Locked Wild that remains on the reels until it participates in at least one win followed by a non-winning spin. For consecutive wins, the multiplier increases by +1. If the Locked Wild is on reel 5 and hasn’t been part of a win, it may randomly move to one of the first four reels.
• Multiplier Stone: If a Serpent Wild with a multiplier lands without triggering a win, it may store its multiplier in the Multiplier Stone above the reels. This stored multiplier is added back to the Serpent Wild the next time it appears, potentially increasing the payout.​
• Serpent Respins: If the Serpent Wild lands without forming a win, it may randomly highlight one type of symbol on the reels. All matching symbols lock in place, and a respin is triggered. Respins continue as long as new matching symbols land, culminating in potentially significant wins.
