Luma begins as a word game, not a lesson. The learning layer follows the words you naturally discover, so your vocabulary list grows from real puzzle moments instead of a generic stack of flashcards.
Every word you find can enter your personal bank automatically. Search the collection, favorite words you want to revisit, and open an entry for definitions, examples, pronunciation, and available etymology or synonym notes.
This makes the bank a record of vocabulary you have actually encountered while solving, rather than a list chosen without context.
Crick surfaces words that are due for review. Correct answers move farther into the future; missed answers return sooner. You can use flashcards or the SRS quiz depending on how actively you want to recall each word.
The mastery view groups progress from CEFR A1 through C1 and counts reviewed knowledge rather than treating every word you have merely seen as mastered.
English learners can use the definitions and level grouping to understand difficulty. Fluent speakers can collect unfamiliar roots, rare-but-fair words, and word families without turning the game into homework.
Luma also supports English, Arabic, and Persian interfaces, including right-to-left layouts where appropriate.
