Are these really from the original patents?

Yes · every toy is redrawn from its real U.S. patent filing (patent drawings of that era are public domain), and each round’s reveal cites the exact patent number and year. The figures are simplified re-drawings in the site’s own style, not reproductions.

How do I know which piece is right?

The missing part is shown as a dashed outline in the drawing. Match the outline’s shape, size and orientation against the detached piece options · only one fits.

What does this train?

Part-whole visual reasoning and attention to structural detail · seeing how a familiar object decomposes into its working parts · plus a little history of the toys themselves.
