SPIN: Sound Maze

SONAR is a quiet puzzle about a single pulse of sound. Tap once and a ring of sound spreads outward across washi paper — it bends off bamboo mirrors, splits at prisms, gathers strength at resonators, and finally reaches the bells waiting in the dark. Turn each mirror to the exact angle, then send one pulse that reaches them all. Sixty hand-tuned levels, five chapters, no timers and no lives. Reflection The opening chapter teaches the only verb you will ever need: turn a mirror. Drag a bamboo rod and the predicted path turns with it, so you can see where the sound will go before you commit. Read the room, find the angle, release. Every level is solvable in a single pulse — the challenge is finding the one angle that works. Splitting A prism splits one pulse into three. Suddenly a single shot can cover paths that no straight line could reach, and the question changes from "where do I aim" to "which branch reaches which bell". Fewer mirrors, more consequences. Energy Sound fades as it travels, and distant bells sit beyond the reach of a plain pulse. Resonator discs restore the wave to full strength, turning an impossible corner into a route — if you can bounce through them in the right order. Terrain Walls close the easy lines, and some of them move. Obstacles slide on a slow, readable cycle with long pauses at each end, so timing is never a reflex test: watch the rhythm, pick your moment, fire once. Convergence Everything at once, with one extra rule — a mirror budget. Three bells, three mirrors on the board, but only two may be active. Choose which pair to use and make a single mirror serve two paths at once. Made to Be Quiet No timers, no lives, no energy meters, no ads, no leaderboards. Ink-wash art on textured paper, a solo guqin score, and soft wooden chimes when a bell wakes. Play a level in a minute or an hour — nothing is counting.
