How do you get arcade on jingle brawl?

Jingle Brawl does not have an "arcade" mode. It is a rhythm game with a focus on competing against other players in real-time.

If you're looking for a similar game with an arcade mode, I recommend checking out games like:

* Beat Saber: A VR rhythm game with an arcade mode that features various challenges and levels.

* Dance Dance Revolution: A classic arcade game with a variety of gameplay modes, including arcade mode.

* Guitar Hero: A rhythm game series that features an arcade mode where players can compete for high scores.

* Audiosurf: A rhythm game where you can create your own tracks using your music library and play them in an arcade mode.

These are just a few examples, and there are many other rhythm games with arcade modes available.
