Frequently asked questions

How strong is the AI opponent?

Stockfish is one of the strongest chess engines available, capable of playing at superhuman strength - most implementations let you adjust the difficulty/depth so beginners and experts alike can find a suitably challenging game.

What are PGN and FEN, and why would I want to export them?

PGN records the full move history of a game (useful for reviewing or sharing a complete match), while FEN captures a single board position as text (useful for setting up or sharing a specific position). Both are standard chess notations recognized by virtually all chess software.

Can two people play against each other on the same device?

Yes - alongside playing against the AI, local two-player mode lets two people share one screen and take turns.
