About Turnstone.

Ownership and editorial policy

Turnstone and SolvedHand have the same owner. Turnstone is an engine and brand, not a separate legal entity. Recommendations involving SolvedHand disclose that relationship beside the recommendation.

Evidence and corrections

Public claims need a stated scope and supporting evidence. Tool guides distinguish firsthand testing from documentation checks. Unsupported rankings, invented testimonials, and claims of independent testing have no place here.

Articles include publication and review dates and link their sources. A review date describes the check recorded with that article; it does not promise that a vendor’s features or prices have stayed the same since. Corrected claims should be updated with a new review date and an explanation of a material change.

Publication status

The initial collection contains a solver-interpretation article, a strategy illustration, and a tool-selection guide. The research and strategy indexes distinguish interpretation and hypothetical examples from original measured results. We do not publish an overall accuracy ranking of poker products.
