Letter Grove
Read full descriptionHide full description
Letter Grove is a quiet, hand-drawn puzzle game about looking closely. Every room is full of objects that hide letters. Slide, rotate, flip and stack the pieces until the letters appear, then type them on the nine-key keypad A–I. Each key disappears once pressed, so no answer ever repeats a letter. • 45 handcrafted puzzles in 5 rooms: a bedroom, a greenhouse, an attic, a clockmaker's workshop and an old library • No math, no codes, no word lists: when the pieces are in the right place, the answer reveals itself • Many puzzles turn the 3×3 keypad into a map: follow a path, a thread or an arrow across the grid • Black-and-white ink drawings, a gentle music-box soundtrack and soft, simple sounds • A progress tree that blossoms with every solved puzzle • The first room teaches the rules and offers free hints; the later rooms are for sharp eyes • No ads, no tracking, no account, plays fully offline
