Joker’s Jewels

Joker’s Jewels — classic sudoku reimagined as a robotic factory shift. Instead of numbers, you stamp part codes into a 9×9 assembly grid. Each 3×3 sector is a production node, and no code can repeat in a row, column, or node. Game features: Factory atmosphere: interface terms like “shift,” “quota,” “defect,” “bolts,” “supply depot,” “livery.” 4 production levels: from Trainee Bay to Overseer Core, with different pre‑stamped slots, defect limits, and reward multipliers. Gameplay tools: notes, Undo, cell highlighting, code keyboard showing remaining parts. Supplies: Scanner Chip, Repair Kit, Auto‑Marker — consumables to assist in tough puzzles. Economy: bolts earned from scores, spent on supplies and livery. Even failed shifts yield rewards. Livery: unlockable color schemes for the entire app, from Assembly Line to Cryo Lab. Leaderboard: local record history with filters, flawless shift badges, and full reset option. Technical implementation: Kotlin + Jetpack Compose, DataStore for saves, Navigation Compose, edge‑to‑edge UI. Joker’s Jewels — sudoku with a guaranteed unique solution, factory‑styled interface, and balanced economy. Play shifts, earn bolts, and unlock new levels and livery.
