Classic English dictionary sources
Build 194 and later contain 97,566 English headwords, plus the original recovered glossary. Earlier test builds differ. Lookup is offline; no network or installed iOS dictionary is required for bundled entries.
Coverage
The historical game-validation list is separate and broader than this reference. An accepted spelling may lack a verified definition. Listed forms and possible base forms are labelled; base meanings do not establish every possible use of a searched spelling. Legacy entries and saved discoveries, including FRIS, are preserved. Spanish interface controls do not translate English definitions or gameplay.

Definition-backed new games · build 195 beta
Build 195 introduces a versioned list of 42,435 four-to-eight-letter English words. Every newly scored word on that policy carries a real source meaning or an explicitly source-listed form and base-word explanation. This smaller playable list is separate from the broader 97,566-headword dictionary. Names, abbreviations and unverified historical entries are not automatically admitted.
Existing unversioned saved games keep their original rules and are labelled Legacy save. They may still contain historical entries without verified definitions; those discoveries and existing scores are preserved. Start a new game to use the definition-backed policy. Exclusion from the new list is not a declaration that a term is linguistically invalid. Controls may be Spanish; definitions and playable vocabulary remain English. This beta information does not mean build 195 is publicly released.
