Glowpane: Logic Puzzle Game

Light a stained-glass window, one piece at a time.

Glowpane is a calm logic puzzle with simple rules: place one piece in every row, every column and every colored zone of the board, and never let two pieces touch, not even at the corners. Every board has exactly one solution, and you can always reach it by logic alone. No guessing, ever.

HOW IT PLAYS

• Double tap a cell to place a piece. It’s checked right away.

• Tap once to mark a cross, a note for yourself. Drag your finger to cross off several cells in one stroke.

• A wrong piece costs a heart. You have three hearts per round.

• Stuck? From level 6 on, each round gives you three Hints and one Reveal. A Hint highlights the next logical step and tells you why it works. A Reveal places one correct piece.

• Your first board walks you through the rules, step by step.

WHAT’S INSIDE

• 100 levels in ten chapters, growing from 5×5 to 10×10.

• Each chapter is a stained-glass window: Ruby, Amber, Honey, Lime, Emerald, Turquoise, Azure, Sapphire, Amethyst and Fuchsia.

• From the third window on, every chapter ends with a hard board.

• Earn up to three stars on every level. A round with no mistakes earns all three.

• Each level you clear lights a petal of the chapter’s rose window. Three stars thread it with gold.

• When a board is solved, the glass replays your solve, piece by piece.

• Night scenes glow behind the board: a chapel at vespers, a moonlit library, a midnight nave, a cloister under the northern lights, a rose window at dawn and a starlit observatory.

• Gentle sounds and haptics.

THE DAILY PUZZLE

• A fresh 10×10 board every day, the same one for every player.

• Solve it day after day to grow your streak.

• Shields keep your streak alive through a missed day. You start with one and earn another every seven days of your streak, holding up to two.
