The rules
The glass starts 65% full. Drag the bottle down or right: water starts when the bottle tips far enough. Starting the flow commits at least 4% of the glass from a 14% bottle; keep tilting to add more. Release to stop, but the committed amount and drops already in the air finish falling. A pour has a three-second safety limit. Pass the shared phone only after the water settles; in a room the next player uses their own phone. Water reaching the visible rim loses the round. No names or motion-sensor permission are needed on a shared phone. Keyboard: hold the right arrow to tilt, release to stop.
What you need and how to start
Choose Overflow and start on one shared phone. You do not need to enter names or a player count. Take turns with the same phone. You can also create a room for one phone per player.
In a room, choose the game first. Everyone, including the host, taps I’m ready. The host then taps Start to begin.
