Build a robot. Teach it to find its way. Watch it come alive! Wobblebots is a wordless robot workshop for kids aged 3-7, with first steps in coding built in. There is no reading at all: your child plays everything without a single word on screen. Pick a head, a body, arms and legs - every robot bounces, hops, rolls or twirls in its own silly way. LITTLE CODER MISSIONS • Lay arrow tiles, press play, and your own robot walks the program • Maze after maze on winding roads: fix a program that goes wrong, fold long walks into counted steps • Keep going through the missions and win the maze maker: build your own with bushes, rocks, ponds, a lamp and a battery to charge on the way - then solve it • The first four missions are free - finish them and a brand-new maze waits every day, free for everyone THINKING GAMES • Which piece is missing? Parts fly onto the robot when you find them • Which robot is the odd one out? • Turn the wooden blocks so the current runs from the battery to the robot • What comes next? Pick the gumball that keeps the pattern going • Flip the cards and find the matching pairs • Put the picture back together, piece by piece • The first levels of every game are free A GENTLE DAILY WORKSHOP • Friendly customers order robots - build exactly what they ask for • Earn hats by finishing the day's orders • When the day's orders are done, a cheeky rival drops by for a dance duel - and always leaves as a friend • A new robot arrives every month HOME AND BEYOND • Give your robot a bath with bubbles and ducks, cook a soup in the kitchen • Build a rocket and hop planet to planet across the solar system - every planet free • Paint every part, pick a scene, compose a dance • Stand your robot in your own room with the camera FOR GROWN-UPS • A daily play time you set behind the grown-up button: in the last minute night falls, then the robot goes to bed until tomorrow • No ads, no subscription, no data collected, works offline • Progress syncs with your own iCloud • One optional purchase unlocks everything, for the whole family Privacy: https://vilusion.com/wobblebots/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
