TheseJugs — the water jug puzzle game

TheseJugs is a free browser puzzle game. You have a few jugs of fixed size and no markings. Pour water from one jug into another — a pour runs until the source is empty or the target is full — and reach the goal amount in as few pours as possible.

There are 800 handcrafted levels, ordered easy to hard, each with a par and a three-star rating, plus a global leaderboard. It plays fully in your browser, free.
