Minesweeper, reimagined. Five difficulties on boards certified solvable by logic alone, in twelve themes built to be looked at. Onyx is made from proportion, material and restraint. The board is the only thing on screen asking for your attention. CLASSIC PLAY • Five balanced difficulties, from Beginner to Extreme • Logic fields, certified solvable by deduction alone • Random fields, for the traditional challenge • Custom fields shaped to your own size and mine count • Infinity mode with a board that expands as you explore • A safe first move on every board, every time FAIR BY CONSTRUCTION Logic fields are laid out uniformly at random, then certified solvable before you ever tap. Nothing is shaped to be safe, so the fields keep the real game's clusters, open pockets and ragged edges - Onyx simply refuses any layout its solver cannot finish. TWELVE THEMES, SIX FAMILIES Bronze and Pearl. Silver and Frost. Oxblood and Rose. Ink and Porcelain. Verdigris and Sage. Aubergine and Lilac. Each family is a light and a dark twin, with themed, classic or mono number colours. A HINT, NOT A HANDOUT Hints walk you through the reasoning before showing the answer, using only the clues already visible to you. Covered cells are never inspected. ALSO INSIDE • Find the Mine: short deduction puzzles with adaptive difficulty and a rating • The Daily: one board, everyone, the same day, with streaks and a spoiler-free share • Chording, quick-open numbers, adjustable reveal speed, sound and haptics • Records for every field, with assisted and unassisted times kept apart • VoiceOver, large touch targets and reduced-motion alternatives throughout PRIVATE BY DESIGN Onyx works completely offline. No accounts, no ads, no in-app purchases, no tracking. Your games, settings and records remain on your device. Take a breath, read the field and find the next certain move.
