The rules
Each turn starts with a full bottle. Drag gently upward to pour; release to stop. The controls are sensitive. Pour a little or all, but some water must land in the tank. Pause and resume the same bottle. When water settles, tap Next player. Whoever overflows the tank loses. Keyboard: hold Up and release. One shared device needs no room; connected play is optional.
What you need and how to start
Play on one shared phone. No names or player count needed.
In a room, everyone taps Ready, then the host starts. Internet and JavaScript are required.
