Foldhouse
A block puzzle that carries a real Japanese floor arrangement as its rule.
What it's about
Foldhouse is a premium block puzzle for people who like block-builders but are done with the casino-reel vocabulary of the genre mainstream. The mechanical core is the shukugi-jiki rule — a real geometry constraint from Japanese tatami residential tradition: four mat corners must never meet at a single point. You place mats across five historically researched worlds — from the Kyoto townhouse (Kyō-Machiya) through the tea ceremony hut (Chashitsu) and the temple sub-room (Otera) to the travelers' inn (Ryokan) and the old farmhouse (Kominka). Terms like heberi (border), hanjō (half-mat) and tokonoma (alcove) arrive with their first translation in parentheses, without lecturing.
What makes it different
What sets Foldhouse apart: the rule is engine, not theme. Tatami tiling is mathematically NP-complete — difficulty comes from the geometry itself, not from synthetic difficulty tiers. World transitions aren't reward animations; they're a single solo note followed by three seconds of silence. Combo streaks earn 200 milliseconds of audio mute instead of sound escalation — silence as feedback, not confetti. Each world changes only the lead instrument (solo koto in the Kyoto townhouse, shōmyō fragments and a temple bell in the Otera, solo shakuhachi in the farmhouse); the geometry rule stays identical — temple included.
Style, pricing, values
The visual direction is hand-painted top-down: a muted earth palette, patina, Tanizaki shadows as substance. Audio is solo koto and solo shakuhachi, world-specific, with a native Japanese audio reviewer sign-off. The Y1 MVP listing is Foldhouse: Igusa — five worlds, 80–100 levels, six to nine hours of play. The full version unlocks after the first world (the first world plays free as a demo), optional expansion packs — no subscription, no loot boxes, no energy timers, no push notifications, no tracking. Foldhouse is built as a platform for culturally grounded geometry rules from global material traditions — future editions ship as standalone apps.
