What's New in Building Boss Go! Idle Tycoon
3.0.9
August 17, 2026
1. New System: Recommended Neighbor Summons Added a feature where you can view a recommended list before summoning and manually select the neighbor you wish to summon. 2. New System: Visit Neighbor Buildings You can now visit neighbor buildings and explore their interiors. (Note: If the user you are visiting has not updated to the latest version, entry may be restricted, or the building may appear incomplete—such as having many empty rooms and level 1 stores. Existing users simply need to change the interior of each floor or place items for it to display correctly to visitors.) 3. New System: Street Mode News UI Added a News UI in Street Mode to check announcements and user news. A news ticker will appear at the top of the screen, showing various updates from other buildings. You can also directly summon buildings featured in the news to a location of your choice. 4. Interior Change UI Improvement The UI has been improved so you can view the full list of selectable options at a glance when changing store interiors. 5. Major Overhaul of Early Main Quests To ensure smooth early growth for our players, the main questline has been significantly shortened, and various installation quests can now be completed for free. Additionally, an 'Optional Item Reward' system has been applied to some main quests. (We are positively considering expanding this reward system when revamping sub-quests in the future.) 6. Building Expansion Balance Adjustment Blueprint requirements have been eased. They are now only consumed when building 'every 5 floors (10th, 15th, 20th...)' starting from the 10th floor. Although the amount consumed on these specific floors has slightly increased, the overall blueprint requirement for the game has been vastly reduced. 7. Floor Construction UI and Cost Revamp The floor construction button now intuitively displays the construction cost in 'All Floors Mode' instead of on the roof. Furthermore, floor construction now only costs 'Coins' instead of Cash, and the required cost has been significantly reduced. 8. Cleaning System Balance Buff The amount of cleanliness restored when tapping the screen to clean stores has been vastly increased. Now, you can easily maintain cleanliness with just a few light taps. 9. Intuitive Sales Effects When an item is sold in the My Building interior mode, the item icon and earned profit will now immediately appear at the sale location. 10. Store Level Up Cost Reduction The cost required to level up stores has been significantly reduced, making growth much easier. 11. Other Improvements and Bug Fixes Fixed an issue where some name fonts did not display correctly. Various other quality-of-life improvements and balance adjustments have been applied.
