"Crash Arena Turbo Stars" (also known as "CATS: Crash Arena Turbo Stars") is a popular mobile game developed by ZeptoLab, the same company behind the famous "Cut the Rope" series. In this game, players design and build battle robots from a variety of parts and then enter them into arena battles against other players' robots. The goal is to destroy your opponent's robot while protecting your own.
The game features a "dream mode" or "dream league" where players can compete in special events and challenges. This mode often introduces unique rules or conditions to the standard gameplay, making it more exciting and challenging. It's possible that "夢遊" (mèng yóu) is referring to this dream mode or a similar feature in the game, where players can engage in imaginative and creative battles with their custom-built robots.
To participate in the dream mode or any other mode in "CATS: Crash Arena Turbo Stars," you would typically need to download the game on your mobile device (it's available for both iOS and Android), create a profile, and then start building and battling your way to the top. The game is free to download but may include in-app purchases for additional parts or currency.
