The river ends at the edge of the paper. Does that mean a piece is missing? At the fictional Kawa House gallery, a new label accuses a conservator of losing part of a painting. As catalogue editor, you inspect the measurements, the maker’s note and three display proposals. Two simple folds reveal a second view, and a different way to understand the work. The Folded River is an original, English-language print-and-play mystery inspired by Japanese folding screens. It combines document-based deduction with a reversible paper reveal. It is a modern fictional paper study, not a traditional Japanese ritual or a replica of an antique screen. No Japanese knowledge is needed. PLAY: 1-3 players, recommended age 13+. Four connected investigation stages, three progressive hints per question, complete solutions and an ending. An optional expert case uses the same evidence to investigate the studio’s record. No game master, external research, app, internet connection after download or extra payment. TIME: Estimated 30-50 minutes for the main game, plus 10-20 minutes for the expert case. Cutting and folding: about 3-5 minutes. These are design estimates; blind human playtime has not been measured. There is no timer. PRINT: Choose A4 OR US Letter. Print one 7-page game version, single-sided on ordinary paper, at 100% / Actual Size. Fully solvable in black and white. You need scissors, a pencil and a table. No card stock, glue, backing board, transparency or double-sided printing. Paper handling is part of the game; phone-only play is not intended. FILES: Start guide (2 pages); A4 game (7 pages); US Letter game (7 pages); progressive hints (12 pages) plus offline HTML; solutions and ending (4 pages); expert case (1 page); expert hints and answer (4 pages); terms (1 page). Eight PDFs, 38 pages in total, plus HTML, FAQ, README and font licences. Print only ONE game version: 7 sheets. All other files can be read on screen. BEFORE YOU BUY: This is a digital ZIP download. No physical items are shipped. Extract it and open 00_Start_Here.pdf. The puzzles and ending stay the same on replay. Generative AI assisted the writing, puzzle design, original illustrations, vector diagrams and layout. Digital checks were performed. Physical printing, blind human playtesting and independent native-English editing have not been performed. Playtime, difficulty and commercial quality have not been independently validated. USE: Private play for the buyer and a group of 1-3 together. Reprints for that group are allowed. No redistribution, resale of files or printouts, public uploads, commercial events or repeated institutional use. Spoiler-free impressions and a photo of the cover are welcome. Please keep full puzzles, the completed fold, answers and ending private. For defects, contact this BOOTH shop with the filename, page and device details. Payment options and availability depend on BOOTH and your payment provider; worldwide checkout is not guaranteed.
