TRIAD: Jewel Logic Puzzle

TRIAD is a calm, jewel-toned logic puzzle. Fill the setting tray so every row and every column holds exactly two rubies, two emeralds, and two sapphires. One short rule, deep deduction, and a solution you can always reason out — never guess. THE RULE (you'll have it in seconds): Every row and every column must hold two of each cut: two rubies, two emeralds, two sapphires. The same gem can never fill a 2x2 square. Some neighbors are linked — a dot means they match, a cross means they differ. Every puzzle has exactly one solution, and every gem can be proven by logic alone. HOW YOU PLAY: Tap an empty setting to place a gem; tap again to cycle ruby, emerald, sapphire. The board quietly flags only the gem that breaks a rule, so you always know where to look — never a wall of red. Stuck with nothing lit? A gentle check points you to the one piece to reconsider. No timer pressure, no fail state — a puzzle is solved, or not yet. SEVEN JEWELER'S RANKS: Apprentice, Artisan, Expert, Master, Grandmaster, Virtuoso, Luminary. Early boards give you room to learn one idea at a time; deeper ranks ask for longer chains of deduction and more linked neighbors. A 300-level ladder climbs through the ranks, with an endless final rank for when you want more. Ranks unlock by skill — the levels you clear — never by payment. FEATURES: * Daily Gem — one shared puzzle every day, the same board for everyone. Keep a daily streak; a Streak Shield covers the odd missed day. * Celebration on every solve — three cut-gem stars, your finish time, and a "New best!" when you beat it. * Teaching hints — a hint doesn't just place a gem, it explains the deduction, so you improve instead of lean on it. * Share your solve — send your time and streak to a friend in one tap. * Five premium jewel palettes — Amethyst Dusk, Rose Gold, Jade Court, Deep Abyss, and Solar Topaz. Pure looks; the puzzle never changes. * Plays offline. No account. Progress stays on your device. One-hand portrait play, in 60-second to five-minute sessions. WHO IT'S FOR: If you love a short rule with deep deduction — Sudoku, Nonograms, Takuzu, Queens — TRIAD gives you a single elegant constraint and a jeweler's bench to solve it on. If "guess and check" puzzles put you off, you'll like that every gem here can be justified before you set it. NO SUBSCRIPTION: Free to play. Optional one-time purchases if you want them: remove ads, hint packs, a jewel palette, or a Premium unlock (no ads, every palette, and a stack of hints). Every rank and every Daily is free — earned by skill, never behind a paywall. Set the last stone. Solve the triad.
