About this game
Water Pouring builds on the classic water jug problem: the containers have fixed capacities, and you must reach a target amount through filling, emptying and pouring. A pour continues until the source is empty or the destination is full. Think about the space left in each jug, then experiment with the order of operations.
How to play
- Choose a difficulty, then check the jug capacities and the target amount.
- Select a jug to fill or empty it. To pour, select the source and then the destination jug.
- Measure the target amount using the available actions. Undo or restart to look for a solution in fewer steps.
Questions parents ask
Is Water Pouring a water jug puzzle?
Yes. You use jugs with fixed capacities to measure an exact amount. Each pour ends when the source is empty or the destination is full; you cannot stop at an arbitrary mark.
Can we play this at a restaurant while waiting for food?
Yes. Use one phone to discuss the next fill, empty or pour. There is no countdown, so it is easy to put the game down when food arrives.
Is this a quiet waiting room game for parents and kids?
Turn off sound and music and compare the amounts together. We suggest ages 6+ with a grown-up helping read the target and jug capacities.
Is the water jug puzzle free and does it need an app?
It is free to play in your browser on a phone, tablet or computer. No app installation or sign-in is needed to solve a puzzle.
Can we play while waiting in line or share one phone?
A parent and child can take turns choosing the next action on the same screen. Pause the activity and put the phone away whenever the line moves.
