"Retro Bowl" is a popular mobile game that offers a nostalgic experience reminiscent of classic American football video games of the 8-bit and 16-bit eras. As of my last update in October 2023, the game primarily focuses on professional football, allowing players to manage a team, make strategic decisions, and play through seasons.

However, while Retro Bowl itself is centered around professional football, there might be interest or fan modifications introducing college football elements, such as custom team names, uniforms, and rosters representing college teams. The game’s simplicity and charm have inspired a strong community, so it's possible that unofficial mods or updates could exist to give it a college football flavor.

If you’re interested in a college football experience specifically within retro Bowl unblocked Bowl, I recommend checking the game's community forums, Reddit, or social media groups for any modifications or updates that fans might have created to simulate college football.
