Questions
Which Four in a Row rules are used?
Two players alternate dropping a token into a nonfull column of a 7×6 board. It settles in the lowest empty square. Four consecutive tokens horizontally, vertically or diagonally wins; a full board without a line draws. This uses original generic styling.
How does computer play work?
Opponents run only in a bounded local Web Worker. Checkers, Reversi, Four in a Row and Mancala use limited search; other games use simple legal heuristics or dice. Difficulty adjusts search depth where applicable, not dice odds. These are practice opponents, not expert play.
Can I play on a phone?
Yes. Tap enabled squares, tokens or turn actions. Wide boards scroll inside their play area; zoom enlarges small targets, and full screen has a visible exit. Player numbers and symbols accompany colors.
Will my game restore automatically?
Returning to this game restores its own validated browser-local board and recent undo history when storage is available. Normal games never open automatically from the homepage. Restart and New game ask before replacing unfinished progress. Clearing site data removes saves.
Is my board sent to a server?
No. Moves, dice history and saved boards stay on this device. No account, online session or upload is used. Analytics receives no board positions or game history.
