About This Content

FlashBoss - English Core: 1,000 English words for German, Japanese, Spanish, Chinese, Russian and Arabic speakers

Fibonacci spaced repetition and boss fights.

Who this course is for: you speak German, Japanese, Spanish, Chinese, Russian or Arabic, and you want to learn English. Every card teaches one English word — with a translation, a translated example sentence, and study notes in your language. The whole game interface speaks your language too. This page is in English, but the course is not: it meets you in German, Japanese, Spanish, Simplified Chinese, Russian or Arabic from the first card. Arabic, written right to left, plays in the new FlashBoss window.

Who this course is NOT for: native English speakers. It teaches the first 1,000 words of English — words you already know. Your English packs are Adept and Advance, included in the base game, or any of the 'Roots Packs'.

In this pack:

  • 1,000 high-frequency English words in five tiers

  • Translations, example translations and study notes in German, Japanese, Spanish, Simplified Chinese, Russian and Arabic — every card, no gaps

  • 38 reference lessons — word order, articles, tenses — readable in German, Japanese, Spanish, Simplified Chinese, Russian or Arabic

  • Spoken audio for every word and example sentence

  • American English base with a full British spelling option

  • Boss fights guard every gate: no cluster is cleared until its hardest words are mastered

The full word list and all reference lessons for every FlashBoss pack are available on the website, along with a playable boss-fight demo.
