Two-player games on one device

Bottom line: NoCharge’s two-player mode is Pass & Play: two humans, one screen, no network, no account, no AI opponent. The device passes between turns — either through a handoff screen that hides hidden information or a simple “next player” handoff for open boards. NoCharge saves one bounded match record per game, and never player names or match history.

What “two players” means here

• Exactly two humans, taking turns on one device.
• No server, no lobby, no online matchmaking, no cross-device sync.
• No computer opponent. AI is a possible future mode, explicitly separate.

Handoff screens

NoCharge’s shared handoff component is the boundary between turns. For open-board games (Gomoku, Nine Men’s Morris, Checkers) it names the next player over a visible board. For hidden-information games (Battleship when it ships) it hides the board. Either way there is no timer, no “quick, it’s your turn” pressure, and no habit loop.

What NoCharge saves

One most-recent match record per game under nocharge:passplay:match:*: mode, result, score, and timestamp. That is the entire persistence model. Names live in page memory only; a reload resets them. The Privacy page lists the keys, and Clear game data removes them.

What NoCharge does not offer

• Online multiplayer of any kind.
• Player ratings, Elo, or “best on the device” leaderboards.
• Match history or replays.
• Notifications or streaks for Pass & Play.

These are intentional absences, not missing features — see the Pass & Play explainer for the reasoning.

Choosing a game

• Open board, strategy: Gomoku (five in a row), Nine Men’s Morris (mills), Checkers (when it ships).
• Hidden information, bluffing: Battleship (when it ships).
• Quick rounds: Last Token, Tic-Tac-Toe.
