block stack: runner 3d is a minimalist arcade experience focused on timing, balance, and quick reactions. Control a moving block as it travels forward through narrow paths filled with shifting shapes and rising obstacles. Stack blocks carefully to pass through gates, gaps, and elevated platforms while keeping your structure stable. Each run challenges your precision as the speed increases and the path becomes more complex. Clean visuals and smooth motion create a calm yet intense atmosphere where every move matters. Collect points, survive longer runs, and improve your control skills with each attempt. Simple one-touch gameplay makes it easy to start, while smart level design keeps every run engaging and rewarding.
