Ormolu

Ormolu is a puzzle cabinet of eleven historic machines. Rebuild each one part by part in real-time 3D, then calibrate its gear trains. Everything is included in one purchase. RESTORE ELEVEN MACHINES - Antikythera mechanism - Planispheric astrolabe - Grand orrery - Celestial planisphere - Marine chronometer - Pinned music cylinder - Difference engine - Morse register - Curta calculator - Jacquard head - Vernier sextant Every instrument is described part by part: 137 parts in all, from the fusee chain of a marine chronometer to the Saros dial of the Antikythera mechanism. A part only seats once the parts it rests on are in place, and each description names those parts, so every restoration can be worked out by reading. More than one order can be right. Place a part too early and Ormolu tells you what it still needs. GEAR-TRAIN PUZZLES Thirty-three gear puzzles, three per instrument. Pick gears from a tray of tooth counts and fit them as drivers and driven wheels until the train turns at exactly the right ratio, such as the Metonic cycle's 235 lunar months in 19 years. Wrong trains tell you whether they ran too fast or too slow. DAILY CALIBRATION A new two-stage gear puzzle every day, the same for every player, with a streak counter. HINTS, STARS AND RECORDS - Hints point to a part that can go in next, or lock one correct gear in place. Each hint costs a star, and you can switch hints off. - Earn up to three stars on every puzzle. - Records keep your best time, fewest mistakes and stars for each puzzle, along with your streaks. Every number comes from your own play. - Restoring an instrument unlocks its assembly blueprint, laid out stage by stage. BUILT FOR EVERYONE - Every part and gear is a labelled button, so the game can be played with VoiceOver. - Text follows Dynamic Type. - Reduce Motion is respected, and haptics can be turned off. - Layouts are designed for both iPhone and iPad. Ormolu works completely offline. It has no ads, accounts, subscriptions, analytics or in-app purchases.
