Clean Blox | HTML5 Block Puzzle Game

Video Demo

Clean Blox is an addictive, minimalist block puzzle game written in pure, modern HTML5 and Canvas. Players drag color-coded shapes from a bottom tray onto a dynamic glowing grid to complete full rows or columns. Designed for maximum retention, it features smooth visual effects like animated particle explosions, floating score texts, dynamic starfields, and web-synthesized retro sound effects. With no third-party game frameworks or external library dependencies (no Phaser, no Construct, no Pixi.js), the code is lightweight, extremely fast, and easy to reskin or integrate into WebViews, Ad networks, or gaming portals.
