The game uses a card-table perspective or a functionally equivalent single-screen layout, though the exact interface is not verified here. The objective in Fan Tan is normally to play cards into suit sequences beginning with the designated starting rank, extending upward and downward as legal cards become available.

Play proceeds by turns, with valid moves determined by the current sequences. The precise modes, scoring rules, dealing procedure, and progression system for this DOS release are unknown.

No release-specific strategy guide or verified scoring details are available. In standard Fan Tan play, consider whether a legal move opens more cards or blocks an opponent, and avoid spending a flexible card when a safer sequence extension is available.

Because the DOS implementation and rule options are not confirmed, treat these as general Fan Tan advice rather than documented game-specific instructions.
