Lulu's Reef

Dive into Lulu's Reef, where little learners count, spell, sort and paint with a friendly baby octopus! Lulu talks your child through every game, so no reading is needed. Every tap teaches something: numbers, letters, phonics, rhymes, shapes, colors, patterns, memory and feelings. Wrong answers get a gentle "let's try again", and a glowing hint appears before anyone gets stuck. 23 LEARNING GAMES IN 5 REEF ZONES • Number Reef: count the fish, pop bubbles in order, feed Pip the right number of snacks (adding and taking away too), spot which group has more • Letter Lagoon: swim friends home along zigzags, waves and loops to get ready to write, find letters, trace them in the sand, hear first sounds, build simple words, find the pictures that rhyme • Shape Shoal: sort shapes into holes, solve reef jigsaw puzzles, spot the odd one out, match pictures to their shadows, find the way through coral mazes • Color Cove: paint fish, mix colors, finish the fish parade pattern, join the dots to reveal a picture, spot the differences • Memory Grotto: match shell pairs, sort sea creatures into groups, name how a sea friend feels, draw lines between things that go together READ-ALONG STORIES Eight picture-book stories, read aloud by Lulu, with each word lighting up as it is read. Little readers follow along, then tap the words to hear the page again. SING-ALONG SONGS Five songs to sing and dance with Lulu: count to ten, sing the ABC, name the colors and shapes, then tidy up and wave goodbye. The words light up as they are sung, and sea friends dance along. GROWS WITH YOUR CHILD (AGES 2 TO 6) Tell Lulu your child's age and every game starts at the right level for them. Difficulty adapts as they play, and the age moves up by itself each year. A REASON TO COME BACK Every game won earns pearls, and pearls welcome 45 sea friends into Lulu's aquarium, with new ones arriving all month. Decorate it with corals, shells and treasures and feed your fish. Every new word your child meets becomes a sticker in their sticker book, with 121 to collect. Lulu picks a game of the day, and the daily clam hides a bonus pearl. MADE FOR KIDS, TRUSTED BY PARENTS • No ads. Not now, not ever. • No tracking, no accounts, no data collection. Progress stays on your device. • Up to 4 children, each with their own reef, age and progress. • An optional daily play timer: when time is up, Lulu gets sleepy and says goodnight. • Purchases and links are behind a grown-up gate. • Works offline, so it's great for car rides and flights. • A parent zone shows progress by skill. TRY IT FREE Try every game before you buy: five games, one in every zone, are free to keep, and every other game has three free levels. Lulu's pick of the day is open all day, and three stories and three songs are free. One purchase unlocks the whole reef, including future updates, and Family Sharing is on.
