Feature Highlight: Ante Bet
Ante Bet is a special betting mode where the player pays a small additional cost on top of their base bet to artificially increase the probability of entering the game's core bonus feature (usually free spins). It is a kind of 'strategic booster' offered to players who want to enjoy the highlight moments with a higher probability than a regular spin, but at a lower cost than directly buying the bonus game.
Feature Highlight: Multiplier Wild
A Multiplier Wild is a powerful hybrid wild that combines the basic ability of a wild to substitute for other symbols with a multiplier feature that amplifies the payout itself. The core of this feature is not just about connecting a broken combination, but about multiplying the value of the completed winning combination several times over, turning an ordinary win into a high-payout moment.
