Vitral: Queens Sudoku Puzzle

Vitral is a Queens logic puzzle with the glow of stained glass: a sudoku-style brain game with no numbers. Place one light in every row, every column and every colored region, and remember: lights never touch, not even diagonally. Light every pane and the whole window shines.

If you love the Queens game, Star Battle or “two not touch” grids, or the deduction of sudoku and minesweeper, this brain game is made for you. Every Queens puzzle has exactly one solution you can reach by pure logic. No guessing, ever.

PURE LOGIC, NO GUESSING
• A logic game at your own pace: regular levels have no lives and no time limit. The countdown only appears in the optional trials.
• Learn the logic as you play: a 10-page step-by-step tutorial, hints that teach (where to look, why, and then the step itself), a technique guide and an animated example for each new technique.
• Automatic X marks, undo and redo, and drag to mark several cells at once.
• A real difficulty curve: you start in Easy, and each difficulty introduces a new logic technique. Unlock the next one by completing 100 levels or by passing its trial.

2,500+ QUEENS PUZZLES AND A DAILY BRAIN GAME
• 2,500+ Queens logic puzzles: 1,000 levels in four difficulties, from relaxing 5×5 boards to expert 11×11 challenges, plus a story campaign, timed trials and a daily puzzle.
• The Cathedral, a narrated campaign: 20 stained-glass windows and 120 Queens puzzles. Help Clara, a master glazier, bring the light back to a darkened cathedral. Every puzzle you solve lights a pane, and a new scene awaits between windows.
• Timed trials: beat the clock to win a bronze, silver or gold medal. Solve fast and the clock adapts to your pace. One free attempt per day, more with a video.
• A daily Queens puzzle matched to your level, with streaks, reserve candles that save your streak if you miss a day, a monthly calendar and an optional reminder you can turn on in Settings. From the calendar you can play the days you missed (the last week is free).
• Share your solved window: a picture with your time, without giving away the solution.

A BRAIN GAME THAT FITS YOU
• Make it yours: seven stained-glass styles for the board, from Sea glass to Gold, each with a matching app icon. Earn them as you play, or get them all with Vitral Unlimited.
• Light and dark themes, color-blind patterns, high contrast and screen reader support. Available in 12 languages.
• On tablets in landscape, a game panel next to the board: your window's progress, the puzzle's techniques and the controls close at hand.

FREE TO PLAY, ONE PURCHASE TO OWN IT
• Free to play with ads (an internet connection is required). Vitral Unlimited is a one-time purchase with no subscription: no ads, play offline, unlimited hints, unlimited trial attempts, the whole daily archive and an encrypted copy of your progress in your own Google Drive.

How to play this Queens puzzle: each row, each column and each region needs exactly one light, and two lights can never be neighbors. Use deduction to find where every light must go. If you enjoy sudoku, nonograms or other logic puzzles, you will feel right at home.
