Box Size is a fast, casual HTML5 puzzle game that tests your timing and precision. The goal is simple: change the size of the active box so its base fits perfectly into the target opening at the bottom of the screen. Each round gives you one clear objective and a tight time window to match the gap. You can play alone to beat your best score or enjoy short sessions that sharpen your reaction and estimation skills.
The gameplay uses a single control mechanic that stays easy to learn but hard to master. Levels get slightly harder as targets vary in width and appear faster. Box Size rewards steady hands, good timing, and quick corrections. Visual feedback and concise rounds make the game ideal for short breaks or longer runs to improve accuracy and high score.
