The available description identifies Jigsaw! as a puzzle title, but does not reliably document its exact screen layout, piece-handling rules, scoring system, time limits, or level structure.

The objective is therefore best recorded only at a high level: complete a jigsaw-style picture. Specific controls, progression mechanics, game modes, and victory conditions are unknown for the supplied DOS version.

No version-specific strategy can be verified from the available information. In general, inspect the complete image when possible and group pieces by edges, colors, or recognizable patterns, but these suggestions are not documented mechanics for a confirmed release.
