The opening guide frames the archive as a study of shape, sequence, and search across three classical Chinese puzzle systems.
Why These Three Puzzles Belong Together
The source book presents Tangram, Nine Linked Rings, and Huarong Dao as a compact survey of Chinese recreational intelligence games. They are not variations of one puzzle. One is a dissection set, one is a mechanical sequence, and one is a sliding-block board. Their shared value is that each makes abstract structure visible through play.
This archive keeps that structure visible for modern readers. Instead of reproducing source pages, each guide explains the puzzle system, names the mathematical idea behind it, and points back to the relevant source range.
Shape, Sequence, and Search
- Tangram studies how seven pieces preserve area while changing outline, meaning, and symmetry.
- Nine Linked Rings studies how a physical object can be read as a chain of states with recursive rules.
- Huarong Dao studies how a small board creates a large space of possible moves.
How Source Material Is Used
Every page in this library is edited English prose based on the source corpus. Page ranges and chapter identifiers remain visible so that claims can be checked, corrected, and expanded without turning the public site into a transcription dump.
When a claim depends on convention, such as a move count or historical date, the article states that constraint rather than presenting a single number as universal fact.
