I spy with my little eye… a tractor!   Kidi Eye Spy fills the table with a pile of soft felt things and names one of them. Can your child spot every copy of the tractor, the octopus or the pineapple? Each one they find hops into their collection and becomes a sticker.   177 THINGS TO FIND\ Six places to explore: City, Farm, Ocean, Forest, Grocery and Christmas. Every name is spoken aloud in English or Bahasa Indonesia, so no reading is needed.   LOTS OF WAYS TO PLAY\ • Time Trial: thirty seconds on the clock, three more for every round won • Little Spy: big things and no clock, for the youngest players • Daily Challenge: ten new rounds every day, and a streak to keep • Spy in…: one place at a time, on its own picture • Find all the…: animals, vehicles, fruit, red things and more • Odd One Out: everything is the same, except one   A STICKER BOOK Everything found becomes a sticker; find everything in a place and it earns a medal in the sticker book. Tap a sticker to hear its name. Place stickers on any of six scenes (city, farm, ocean, forest, shop and Christmas), drag the corner handle or pinch to resize and turn them, and save the picture.   GENTLE HELP After a few seconds without a find, a hidden copy gives a little wiggle. If that's not enough, a soft spotlight shows the way. No one gets stuck.   MADE FOR SMALL HANDS AND GROWN-UPS' PEACE OF MIND • No ads, ever • No accounts, no tracking, no personal data collected • Plays offline • A grown-ups-only gate in front of the purchase and sharing   FREE TO START City and Farm are free to play.

Nono Blocks Formula is a nonogram logic puzzle game. Use the number clues beside each row and above each column to determine which cells should be dark and which should be crossed out. Each number represents a group of consecutive dark cells. Fill every cell correctly to complete the puzzle. When a row or column matches its clues, the hint numbers turn green. On lower-density levels, the clues may allow more than one possible arrangement. Green means that a row or column fits its clues, but the full grid must still match the puzzle's solution. If all hints are green but the level is not complete, revisit places where more than one arrangement was possible and try a different one. More than 100 levels become progressively more challenging as you advance. Play with simple tap controls on iPhone and iPad, or use a mouse on Mac. Key Features: - Over 100 levels, from beginner to advanced difficulty. - Simple and intuitive controls. - Leaderboards to track your progress and compete with others. - Full VoiceOver support for accessible play. Whether you're new to nonograms or an experienced solver, Nono Blocks Formula offers increasingly challenging logic puzzles as you progress.
