About the game
Jug Measure is a calm logic puzzle about an old riddle. A baby elephant at the waterhole wants exactly four units of water, or seven, or thirteen in its trough, but all you have are a tap, a drain and a few jugs without any markings. You can fill a jug to the top, empty it out, or pour one jug into another. A pour always stops the moment the receiving jug is full or the pouring jug runs dry, and that is the whole trick: the only amounts you can be sure of are the jug sizes and the differences between them.
Thirty puzzles grow from two small jugs to three-jug targets, a trough that adds up whole jugs, and waterholes with no tap at all where you must share out what is already there. Every level is solvable, has a move limit, and gives three stars for the shortest solution. A hint button shows the next move if you get stuck.
