WordForge

WordForge is a free browser game where you build English words from a hand of letter tiles and battle with them. Every word gets a rarity from a 25,000-word dictionary (N, C, R, SR, UR, LG), based on CEFR level and word frequency. Common words are N; rare words like "ephemeral" hit UR or LG for up to 8x points, and words of 7+ letters get a one-tier boost. Modes: AI battles (5 difficulty levels), online matches, and private rooms for 2–4 players. Every word you forge is saved as a collectible card. A study mode has level-based vocabulary quizzes (A1–C2). No install and no sign-up; it runs on phone, tablet and PC. The UI is mainly Japanese, but the words are English. Made solo by a university student in Tokyo, Hakki. Feedback welcome: yantatsuki@gmail.com
