Can you build the tallest tower?
A closer look at what Tower Block does, who it is for, and how it fits into your browsing setup.
Realistic physics make each placement matter: misaligned blocks wobble, lean, and can bring the whole run down. That keeps sessions tense even though rounds only take a minute or two-perfect for short breaks between tabs.
High scores save locally on your device with no sign-up required. Install free from the Chrome Web Store, pin the extension, and open it whenever you want a quick arcade-style challenge.
