Bonus Features

Bonus Only stands out with its unique approach to gameplay, centered around triggering bonus features for all wins. Here’s a breakdown of its key bonus features:

Each bonus feature is launched with its own set of special symbols and offers a different gameplay experience, promising diverse and dynamic sessions for all players.


The symbols in Bonus Only are meticulously designed to fit the casino and dice theme, emphasizing the game’s unique approach. Here’s a closer look at the symbols:

  • Special Symbols: Vegas, Macau, Monte Carlo, and Dice – each playing a critical role in triggering the respective bonus games.
  • Dice Wilds: Acts as a wild card to substitute for any of the above special symbols and can add extra dice rolls.
