Unfinished Window

Read full description

Inside a serene cathedral sanctuary, warm sunlight awaits to illuminate an intricate stained glass rose window... yet the master artisan left the glasswork unfinished. Only you can deduce the missing pieces, restore the sacred geometry, and let the light flood through once more. Unfinished Window is a pure deductive logic puzzle that merges algorithmic mathematics with the timeless aesthetics of Gothic stained glass art. Free of numbers, free of stressful countdowns, and completely free of guessing. [ TWO ELEGANT RULES - INFINITE DEPTH ] 1. Adjacent glass pieces separated by lead lines cannot share the same color. 2. Each 4-piece structural panel must contain all 4 colors exactly once. [ 100% PURE DEDUCTION - ZERO GUESSWORK ] Say goodbye to trial-and-error puzzles. Every level in Unfinished Window is procedurally carved and verified by an automated deductive reasoning solver. There is always a clear, logical step forward using pure deduction (naked and hidden singles) - never a random guess. [ DUAL-CHANNEL ACCESSIBILITY ] Engineered for everyone, including color-blind players. Every jewel color is permanently paired with a clean, high-contrast geometric motif: - Ruby Red: Sun motif - Amber Gold: Moon motif - Emerald Green: Star motif - Sapphire Blue: Leaf motif Rendered with crisp vector lines, with zero reliance on standard OS emojis. [ ATMOSPHERIC ILLUMINATION ] Completing a window rewards you with a moment of serene contemplation. As your final piece locks into place, lead lines illuminate in warm gold, dynamic light rays sweep across the sanctuary, and glowing dust motes drift peacefully through the air. [ CRAFTED FOR MOBILE EXCELLENCE ] - True One-Handed Ergonomics: Palette and controls placed within natural thumb reach. - 100% Standalone Offline Play: The entire puzzle generation engine runs locally on your device. Play anywhere - on planes, subways, or off-grid retreats. - Native Haptic Feedback: Feel subtle, tactile pulses upon piece placement, conflicts, and victory. - Privacy-First Engineering: Zero trackers, zero logins, zero PII, and minimal battery consumption. Step into the quiet sanctuary. Restore the glass. Let the light shine through. Download Unfinished Window today!

About

Rainrelay

A little rain. A garden in bloom. Step inside Rainrelay, a cozy puzzle game set in a clay-style greenhouse. Place a few umbrellas, choose where the rain should go, and find a path to every plant. EVERY UMBRELLA COUNTS Each garden gives you a limited set of umbrellas. Point ordinary umbrellas left or right, use split umbrellas to feed two branches, and leave useful sockets empty so the rain can fall straight through. Some flowerpots pass water to the plants below. Think through the route, then tap Rain to see your idea come to life. 30 GARDENS TO EXPLORE Start with a single turn and grow into puzzles with several tiers, shared streams, and winding paths. Water every plant to finish a garden. Reach both bells in the same successful run to earn all three stars. Retry, undo, and step-by-step hints let you explore at your own pace, without timers or lives. A GREENHOUSE OF YOUR OWN Earn seeds through play and use them to build your collection: 9 umbrella styles, 10 flowers, and 8 decorations. Arrange flowers and furniture, admire your folded umbrellas on the rack, and watch your owned umbrella fabrics bring variety to the puzzle boards. MAKE TIME FOR A LITTLE CALM Swipe around your spacious greenhouse and zoom in on a favorite corner. The light follows your device's local time, while in-game wind and snow bring movement to the view outside. Play the puzzles and enjoy your greenhouse offline. From Garden 04, you can choose an optional rewarded ad for extra seeds when an ad is available; continuing, retrying, and hints remain available without watching one. The collection uses seeds earned in the game. Available in English and Vietnamese, with layouts for iPhone and iPad, sound controls, and a reduced-motion setting. No account is needed to play.
