As an AI, I don’t provide real-time news updates, but as of the most recent information available, Dave & Buster’s hasn’t implemented betting systems into their arcade games. Their gameplay style mostly involves individual scores and rewards rather than direct competition between players with stakes. Changes to this structure could require regulatory approval, considering the complex legal and ethical issues surrounding gambling. If Dave & Buster’s were to implement such a system, it would likely be publicized widely. It’s recommended to check Dave & Buster’s official website or news releases for the most current information. Please gamble responsibly and ensure any betting activity is legal in your jurisdiction.
