FlashBoss combines spaced-repetition vocabulary drills with boss-fight encounters across four languages, from beginner to advanced proficiency. Players work through daily lessons featuring words in context, then face ranked battles that test retention—the game's core appeal lies in making rote memorization feel like progression through a familiar RPG framework. It's designed for language learners seeking structure without the friction of blank flashcard management.

I have started this game with a little knowledge of German I started by doing the BossFight which i found a good challenge. I also do the daily lessons and have found this good with good example sentences. A good way to learn new words and to see them used in sentences. i would recommend this to start learning a new language.
works well on linux, the UI is def a unique and welcome simplification on the old DOS console RPG menus, I quite like it and will def use this over ANKI just due to the pre prepped "cards". 100% a learning tool i would recomend.
This game has been really well thought out. After about 9 hours I’m still remembering the words from earlier levels, which shows how well the mechanics stick with you.
It’s simple to start but gets properly challenging, and it has that classic “one more try” loop that keeps pulling you back in. The boss fights are a lot of fun too and break things up nicely. Really fun little game.
Latin, the first dead language Latin Core is live: the first thousand words of Latin, in the FlashBoss way — 20-word clusters, spaced repetition, a boss at the end of every cluster. We rehearsed the method on two constructed languages, Esperanto and Toki Pona, and learned how far it stretches. Latin is the first language with no living speakers to check us, and the answer is the same. Built to read Latin Core has one purpose: reading real Latin. It is the first 1,000 lemmas of a 2,000-word course — the vocabulary that carries you into actual sentences from the first tier, with grammar introduced step by step and example sentences that never use grammar you have not been taught. In the pack 1,000 high-frequency Latin lemmas across five tiers, in themed clusters Long vowels marked with macrons on every headword Translations and study notes on every card in English, German, Japanese, Russian, Simplified Chinese and Spanish 22 reference lessons — declensions, conjugations and core grammar, tier by tier — readable in the same six languages Every word and every example sentence spoken by a neural voice in Classical (restored) pronunciation Boss-fight graduation: no cluster is cleared until its hardest words are mastered Latin arrives speaking your language Study Latin through whichever of the six you call home: the translations, the study notes and the lessons are all there, on every card, from the first tier. Coming next Latin Pareto 1 — tiers 6 to 10, the second thousand — follows next week and completes the course. About the screenshots Our screenshots lag behind the game. If a pack's page lists a language in its description and its artwork, that language is in the pack, even where a screenshot has not caught up. Where a screenshot or the website disagrees with the description and the artwork, the description and the artwork are right.
English Pareto 1 and Pareto 2 are live — and will be discounted with all currently available FlashBoss content during the Autumn Sale. Russian joins as the sixth and final interface language. This is the third major announcement in two months — and the last of the Year of the Horse.Two English bundlesThe complete English course now comes as two editions at one price: the American English Bundle speaks the built-in American voice, and the British English Bundle adds the English (F) voice DLC, which turns every spoken and written word British.Latin — the real thing — this ThursdayLatin Core releases this week: a 1,000-word reading course in actual Latin, classical pronunciation, macrons on every headword, its own trained voice. Not to be confused with Latin Roots, which is an English vocabulary pack built from Latin parts.The next five ThursdaysThis Thursday — Latin CoreThen — Latin Pareto 1Then — Swahili CoreThen — Swahili Pareto 1Then — Swahili Pareto 2After that, you decide: Indonesian or Ancient Greek. Vote in the comments.The update cycle is finishedFlashBoss has been updating on a regular basis for the last six weeks, leading to frequent downloads. Thank you for your patience in the meantime.The biggest change of the cycle lives under the hood: FlashBoss now ships a GPL rebuild of Piper TTS, and on top of it we have begun training voices of our own. Our Esperanto and English (F) voices have been trained in house, as have our classical Latin and Swahili voices to come. Thanks to the Piper project, and to Mozilla and the volunteers of its Common Voice project, whose recordings teach these voices to speak. Hear them all on the voices page. The same engine drives the PiperTTS window: press Ctrl+P on any screen, paste any text, and hear it read aloud, or save the audio to keep.Bugs or content errors will be addressed promptly if reported at: the report page.Good luck to each of you with your learning endeavours,— Master Odiin
French Pareto 2 is live. The last 1,000 words of the French line — Core, Pareto 1 and Pareto 2 now carry French out to 3,000 words.What is in it1,000 words across five tiers and forty clusters, each cluster closed by a boss fight. 566 of them are nouns, every one carried with its article and colour-coded by gender, so le and la are learned with the word instead of after it. Verbs, adjectives and 88 set expressions make up the rest.The notes start flagging register at this level: when a phrase is tu, when it is vous, when it is soutenu. It is the point in French where that begins to decide things.In your languageLike the rest of the French line, every card meets you in German, Japanese, Spanish or Simplified Chinese — translation, translated example sentence, and study notes. Or play the whole thing in English. The lessons come in all five.Pareto 2 follows Pareto 1. If you are starting French from nothing, French Core is the front door.
