Bu Oyun Hakkında

FlashBoss — Learn German vocabulary through spaced repetition and boss fights

Master 3,000 words through native example sentences, Fibonacci-timed review sessions, and battles that prove what you know. Built by a CELTA-certified language teacher. Suitable for ages 12+. No subscription.

The Core Loop

Each day, you'll review flashcards using a Fibonacci-based spaced repetition system. Cards you know well appear less often; cards you struggle with come back sooner. Maintain your daily streak to build momentum, or use the Grimoire to bank extra days of practice as "Drive" — insurance against life getting in the way.

Boss Fights

Vocabulary is organized into thematic clusters, each guarded by a boss. Defeat the boss to purge your deck of mastered content and advance through tiers. One step forward, two steps back: An incorrect answer pushes you toward the edge, a correct answer drives you forward!

Choose Your Master

Six masters offer different philosophies and session limits:

• Luna — Gentle and encouraging, limits daily Grimoire sessions to prevent burnout

• Claude — Analytical and precise, unlimited sessions for the self-directed

• Odiin — Stoic warrior-poet, unlimited sessions for the dedicated

• Shen — Wise and measured, moderate session limits

• Kitsune — Playful trickster, unlimited sessions with a mischievous edge

• Aquila — Noble and disciplined, moderate session limits

What's Included

The base game includes German Core and Esperanto Core — 1000 words each with full example sentences and text-to-speech audio pronunciation. FlashBoss is designed to get you from zero to interacting in the target language. Additional vocabulary packs are available as DLC.

Why Terminal?

FlashBoss runs in a terminal for that retro aesthetic and lightweight footprint. Language education shouldn't require expensive equipment.
