Tower Builder HD is a free arcade game for Android developed by Dumitru Hristov. The game is all about building the highest medieval tower without a crane. To achieve this, you have to drop new pieces onto the previous ones as accurately as possible. The game ends when you drop a blackrock piece, which doesn't fall on the previous piece.

To build the tower, you must drop the pieces accurately while ensuring that none of the overhangs break off. Each new piece you drop will be the same size as the previous one, and the smaller they get, the faster they move before you drop them, making it harder to be accurate. Your game achievements are visible and bring eternal glory, and your builder's craft protects the city.

Tower Builder HD is a challenging game that requires precision and concentration. It's perfect for those who enjoy arcade games and want to test their building skills.
