Rainrelay
Read full descriptionHide full description
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.
