Bottom line: The handoff screen is NoCharge’s shared component for two players on one device. It hides the board before a turn change so a player with hidden information (ships, letters, planned strokes) cannot see the next player’s move, shows whose turn is next, and continues only when the next player taps the button.
When it appears
- Hidden-information games (for example Battleship when it ships): the screen replaces the board; the next player taps Continue to reveal only their side.
- Open-board games (Gomoku, Checkers, Nine Men’s Morris): the screen briefly identifies the next player before the shared board returns.
Every Pass & Play game page embeds the same component, so the behavior is consistent instead of per-game.
What it never does
- It does not show the previous player’s private information after the pass.
- It does not save names, timing, or pass counts. Nothing about the handoff itself is persisted.
- It does not include a timer, a “hurry up” message, or a score for passing speed.
- It does not handle network turn-taking; this is strictly local.
Limits
The screen protects the boundary between turns, not the room. It cannot prevent a player across the table from glancing at a shared open board, and it is not a network privacy feature. For true remote play, NoCharge intentionally offers nothing — that is out of scope by design.
