About

Start with a tiny three-floor building and grow it into the landmark of the street. Fill it with shops, draw the crowds, and build all the way to the top in Building Boss Go!, the cozy building tycoon. ■ A building full of customers Cafes, bakeries, sushi bars, karaoke rooms, PC cafes, dental clinics, even a talent agency. Dozens of shops are waiting to move in. What goes on each floor is up to you. Stock products, run sales and promotions, and watch regulars appear as your shops grow. Lend a hand to busy staff for extra income, and listen to what customers say on their way out. Rain keeps people home. A rainbow brings the whole street out. ■ Decorate it your way Walls, roofs and signboards. Fences, streetlights, fountains, food trucks, pinwheel paths. Inside and out, every corner is yours to design. Collect pieces to craft interior items, fill your shops with them, and more customers will come. Add facilities like elevators, CCTV and nursing rooms to keep your tenants happy. ■ Meet your manager team Dexter is smart but still learning. Lily has a head for numbers. Max is all muscle and confidence. Justin is a hip-hop musician. Hire managers with real personalities, put them in charge of your building, and send them out to earn. ■ A street shared with neighbors Other owners' buildings line your street. Drop by to look around, and summon the ones you like as neighbors. Host a giveaway to pull in crowds, and every neighbor who visits goes home with a gift. Climb the weekly rankings by growing your building the most, and reach floor 70 to enter the Hall of Fame. ■ Season 2: Boss of the City Once your building stands on its own, head into the city. Buy buildings across town, rent vacant floors to tenants, and become a landlord. Go easy on struggling tenants, charge more when business booms, and keep risk in check with facilities and special care. ■ Take a break anytime Shops serve customers and earn on their own. Come back and a settlement report is waiting with everything you made. Earn pocket money sorting mail, packing boxes or winning rock-paper-scissors matches, and solve surprise quests from your tenants. Light like an idle game, deep like a business simulation. Open your first building today.

What's New in Building Boss Go! Idle Tycoon

3.1.0

October 12, 2026

What's New in 3.1.0 ■ Weekly Rankings (New) Compete with owners in your country on how much your building score grows each week. A new week starts every Monday at 9 AM (KST), and last week's top 100 receive rewards. · 1st: 20 Diamonds + Golden Trophy / 2nd: 10 Diamonds + Silver Trophy / 3rd: 5 Diamonds + Bronze Trophy · 4th–10th: 5 Diamonds / 11th–25th: 3 Diamonds / 26th–50th: 1,000 Cash / 51st–100th: 500 Cash · The top 3 get a Red Carpet in front of their building and the top 10 a Lobby Archway, for one week. · Tap an owner in the rankings to view their building and summon them as a neighbor. · Raising your score by illegitimate means (hacking, etc.) may result in a ban without notice. ■ Hall of Fame (New) Total-score rankings for owners who have reached floor 70. ■ Giveaway Events (New) From level 20, host a giveaway at any of your businesses. Customers increase during the event, and neighbors who visit receive interior item prizes. · Standard (1 Gold Bar, 2 h, +15 customers) / Deluxe (500 Cash, 4 h, +30) / Premium (1 Diamond, 6 h, +50) · Prize odds are shown before claiming. When the event ends you gain 1 Popularity per 3 visiting neighbors. Events can be held every 6 hours. ■ Settlement Rework & Staff Payroll · Taxes, manager salaries and business upkeep at settlement are gone. Settlement now pays income only, and higher rating grades require more operating income accordingly. · Businesses without stock (services, hospitals, offices) pay staff payroll in coins every 10 minutes automatically. If you run short, payroll falls behind (up to 3 times) and the business slows down. Nothing slows down while you are offline. · Tax and real-estate businesses and some roofs (water tank, solar, wind, lightning rod) now reduce payroll, up to 50% combined. · The Secretary Team is now the Manager Team. Managers help run your building with no salary. ■ Convenience · A sales graph at the top of the business screen shows recent sales by minute, hour or day along with business status. · Recover and Restock are merged into Clean & Restock, also available from the offline income window. · The business window gets Status, Customers and Score tabs. Sales score is now based on your best record, so it no longer drops with momentary sales. · Tap your building on the street to see your best score, this week's best-score gain and current score. · The news list shows more items and scrolls. · Send Feedback added to Options. We'd love to hear from you! ■ Visuals & Fixes · New app icon and title image; loading illustrations updated and added. · Improved layouts on tablets and foldables. · Fixed floors appearing empty or visits being blocked when visiting neighbors, the wait screen lingering after cancelling account linking, overlapping text, and more. ※ Please update to the latest version for smooth neighbor visits and giveaway participation.
