Seishin - Zen Puzzles

A quiet room for your attention. Seishin is a brain training game built around one short daily practice: three different puzzles, about three minutes, then you are done. No endless feed, no session that never ends — a small, finishable ritual. SIX PUZZLES, SIX SKILLS One Stroke — trace a single unbroken path through every cell, in order. Planning and spatial reasoning. Waterway — rotate the pipes until water reaches every channel. Planning and spatial reasoning. Stone Path — study a pattern, then rebuild it from memory. Pattern recognition and memory. Hue Recall — hold one colour in mind, then find it again with hue, saturation and brightness. Memory and focus. Triplets — spot the sets where every trait either matches or differs. Pattern recognition and focus. Squares — divide the board into exact rectangles, one clue each. Logic and spatial reasoning. A DAILY PRACTICE, NOT A GRIND Each day draws three different games and puts them in order. Finish the run and the day is yours. Because the games rotate, you never drill the same skill twice in a row — and when you want more, every puzzle stays open to play freely. SKILL TRACKING THAT MEANS SOMETHING Six scores — Focus, Memory, Planning, Spatial, Patterns, Logic — each moved only by the games that genuinely train it. Scores blend over time, so one poor round never erases a month of work, and the progress screen shows you what moved. QUIET BY DESIGN Seishin draws its look from traditional Japanese pigments: vermilion and indigo, pine green and sumi ink on unbleached paper. Seigaiha waves in the background, an ensō ring for your progress, a hanko seal when a puzzle is done. Light and dark, both drawn by hand. NOTHING LEAVES YOUR PHONE No account. No ads. No subscription. No analytics and no tracking of any kind — the app makes no network requests at all. Your progress lives on your device and nowhere else, and everything works offline. One optional reminder a day, at an hour you pick. Off until you turn it on.
