Hi Product Hunt, this is Brimful, from Teamz Lab. In most water sort puzzles every tube holds the same amount, so once you can see the colours the pouring is just bookkeeping. We changed one rule: every jar is a different size. A small jar will not take a big pour, so you plan space as well as colour. What is in it: - Jars from two to six measures. Each colour has exactly enough liquid to fill one jar of its own size. - Tap a jar, then tap where to pour: onto the same colour or into an empty jar. A jar never overflows. - Three colours on level 1, eight colours by level 6. - No timer, no lives, unlimited undo. - Every level starts from a solved board that was scrambled with legal pours, so it can always be finished. What it is not: it is not a ball sort game, and there is no clock to beat. You can still pour yourself into a corner. The game tells you when no moves are left, and Undo takes you back. It is on iPhone and Android, free to play and supported by ads (an ad after some level wins). There is also a browser version at tool.teamzlab.com/games/brimful/. One question: do jars of different sizes make a water sort puzzle more fun for you, or do you prefer identical tubes?
