Read full descriptionHide full description
Turn turtles into stepping stones and get the bunny to the carrots! ZeroRoad is a number puzzle set in a peaceful pond. The number on each turtle's shell is how far it can swim. Every square it moves lowers the number by 1, and at exactly 0 it tucks into its shell and becomes a stepping stone. Link the bunny's island to the carrot island and the stage is clear! 【How to Play】 - Drag a turtle to swim. Each square lowers its number by 1 - Let go at 0 and it tucks in to become a stepping stone - Lily pads are ready-made stones. Turtles can dive right under them - Tap a placed turtle to send it back home - Connect the bunny to the carrots to clear the stage 【Key Rules】 - Rocks and islands can't be entered - Turtles can pass over lily pads and other turtles. That square still costs 1 - A turtle can't reach farther than its number. Which turtle, in what order, to where? That's the puzzle 【2,000 Stages】 A short animated guide shows the rules, and the first 7 stages are a hands-on tutorial. Ponds grow as you progress, with lily pads and rocks shaping the way. Difficulty rises and falls in waves, so a tough stage is followed by a breather. - No lives, no timers, no stamina - Progress is saved, so you pick up where you left off 【Stuck? Use a Hint】 Pick any turtle and use a hint on it: it glows gold, swims to its right spot, and locks in place. You start with 5 hints; watch an ad to get more. 【Features】 - Simple drag and tap controls in portrait mode - A cozy low-poly 3D pond with an adorable bunny and turtles - Separate volume sliders for music and sound effects - Reset a stage anytime 【Perfect For】 - Fans of number puzzles, logic puzzles and brain teasers - Players who love thinking games like Sudoku or Sokoban - Anyone who wants a relaxing brain workout with cute animals - Commutes, queues and short breaks Count the turtles down to zero and build the road. 2,000 stages: can you get the bunny home?
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.
