Elena Castillo

Elena Castillo is a senior crossword puzzle editor with more than seven years of experience in mobile word games. She specialises in grid-fill word puzzles of the type pioneered by Words Mobile, the developer behind Crossword Quest. Her role on Crossword Quest Answers is to verify every level answer, maintain the searchable database of 20,000+ levels, and ensure that every page on this site reflects the current state of the live game.

Crossword Quest presents a distinctive challenge compared to traditional crossword formats: rather than solving across and down clues, players connect letter tiles to fill predefined grid shapes. The game’s levels span simple 4-letter words at the beginner end to complex 8-letter fill-ins requiring knowledge of less common vocabulary. Elena evaluates each level with a focus on the letter set provided — understanding which fills are possible given the available tiles is the core skill the game develops.

With over 20,000 levels in the Crossword Quest catalogue, maintaining a complete and accurate answer database requires systematic verification rather than ad-hoc spot-checking. Elena maintains a structured workflow: new levels released in app updates are captured within 48 hours, and any player-submitted correction is cross-referenced against the live app before the database is updated. Every level on this site carries Elena’s personal verification.

Elena has a background in English language teaching, which gives her an advantage when evaluating the vocabulary range of Crossword Quest’s later levels. Words Mobile tends to introduce more specialised terminology — scientific names, formal registers, archaic terms — in levels beyond 10,000. Elena flags these for additional verification and often provides contextual notes where a word’s meaning is not immediately obvious from the game’s presentation.

In addition to level answers, Elena manages the site’s word search tool, which allows players to look up any answer word and find every level where it appears. This reverse-lookup feature is especially useful for players who recognise a specific word from a previous puzzle but cannot recall which level it came from.

Elena also monitors the Words Mobile developer’s update cadence. Crossword Quest receives irregular content drops — sometimes 50 new levels at once, sometimes 500 — and Elena tracks the release notes and level-count changes to ensure the site’s coverage stays current. She is reachable through the contact page for correction reports or to flag a specific level that appears out of sequence or incorrectly labelled.
