Glass Quest is a free online puzzle game where your goal is simple: drop colorful balls into a glass and fill it to the top without letting any spill over. Each level tests your aim and timing as you carefully place every ball inside the cup. One wrong move and you lose a life — and you only get five per level, so precision matters from the very first drop.

What makes Glass Quest genuinely addicting is how quickly the challenge ramps up. Early levels feel straightforward, but the angles, ball sizes, and cup positions keep shifting, forcing you to slow down and think before you drop. There are no complex controls here — just point, release, and watch the result. It sounds easy, but keeping that glass full without a single spill is harder than it looks. The hypercasual format means rounds are short and satisfying, perfect for quick sessions between tasks.

If you enjoy casual skill-based puzzle games, ball drop challenges, or precision arcade games, Glass Quest hits that sweet spot between relaxing and frustrating in the best way. It's a great pick for fans of physics puzzles, aim-and-drop games, and simple browser games that don't require any download or sign-up. Whether you're looking for a quick brain break or a free HTML5 puzzle game to sharpen your focus, Glass Quest delivers clean, satisfying gameplay every time.
