In Sunday City, businesses unlock as you progress along the Trophy Road. Each new level brings fresh opportunities to expand your empire with different types of businesses.

Once you’ve unlocked a business, you can buy and upgrade its parts, renovate the interior, hire staff, and purchase materials needed for improvements. Some businesses may not require certain upgrades or materials, while others rely on them heavily. When you finish all available upgrades in a business, you’ll be ready to move forward and unlock a brand-new one.

Upgrades you make doesn’t just improve the business itself—they also push your progress along the Trophy Road. Completing businesses and leveling them up is one of the key ways to strengthen your city presence and unlock even more opportunities.
