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.
