- Paste one of the codes below exactly as shown (case-sensitive, mixed case).

When Do New Build a Tower Codes Drop?
The Build a Tower dev drops codes at version milestones (T4UPDATE for 18,000 Cash, T5UPDATE for 38,000 Cash as the biggest stacker), and starter or identity drops (Tower for 20,000 Cash as a launch-period bonus).
🎮 About Build a Tower
Build a Tower is a Roblox building sim where you stack floors, add themed rooms, and race rival players to have the tallest tower with the most income per minute.
T5UPDATE drops 38,000 Cash (the biggest stacker), Tower drops 20,000 Cash, and T4UPDATE drops 18,000 Cash.
Cash pays for new floor slots and themed room upgrades, so stacking all three codes on a fresh account gives a serious head start on the tower-height race.
No older codes have rotated to expired yet in this cycle, but the dev drops new codes at each Tower update version milestone.
All codes in this list are case-sensitive and released by the developers of the game. Codes can expire without warning; if one shows invalid, it was already rotated out.
