Clean Stack

Place moving blocks with exact timing and keep the tower balanced.

Created for simple, satisfying interactions, this extension brings a compact experience directly into your browser. Its interface keeps the focus on the essential action while providing clear feedback and responsive controls throughout every session. The Chrome Web Store version makes the experience instantly accessible whenever you want to play. Open the extension, begin a new attempt, and get straight into the action without complicated menus or unnecessary steps. Every element is designed around clarity and consistency, creating a lightweight experience that is easy to understand but increasingly demanding to master. Short attempts can quickly turn into extended sessions as you try to improve your result. A block moves continuously from side to side above a growing tower. Click at the right moment to place the moving block onto the top of the structure. Precision determines how much of the block remains. Any portion extending beyond the previous block is cut away, leaving a smaller platform for the next placement. As the tower grows, the available surface becomes increasingly narrow. Small positioning mistakes can quickly make future placements more difficult, turning every click into an important decision. The objective is simple: build the tallest tower possible. Find a consistent rhythm, improve your timing, and keep each new block aligned as accurately as you can. One missed placement can end the run, so maintaining precision becomes increasingly important as the height increases. Try again, refine your timing, and beat your previous tower record.
