Line Up: Dots | HTML5 Space Puzzle Game

Line Up: Dots is a premium HTML5 space-themed puzzle game built with pure HTML5, CSS3, and vanilla JavaScript. No frameworks, backend, database, or external libraries are required. Players connect numbered stars in ascending order while avoiding obstacles, using portals, and racing against the clock to complete each level.

Designed for both casual and puzzle enthusiasts, the game offers 50 handcrafted levels divided into six progressively challenging difficulty tiers. As players advance, new mechanics such as asteroid fields, portals, timers, and increasingly complex layouts create a rewarding gameplay experience.

Because the game is 100% client-side, it can be deployed instantly on virtually any web hosting service or embedded inside mobile applications using a WebView. There are no server-side dependencies, no installation process, and no ongoing maintenance costs.
