All aboard for ABC Trains! ABC Trains turns early learning into a big, bouncy toy-train adventure for toddlers and preschoolers. A friendly voice guides every step, a chunky little train rolls up with the answers, and the whole world dances to the music when your child gets it right. WHAT YOUR CHILD WILL PRACTISE - Letters: find capital letters and little letters. As your child gets better, look-alikes such as b, d, p and q join in. - Letter sounds: "Which one starts with B?" Pictures of apples, balls, cats and more help connect each letter to its sound. - Numbers 1 to 20: spot the number, hear it, say it. - Counting: load ducks and cupcakes onto the train, or tap each one to count them out loud. - First sight words: 40 little words like "the", "see" and "look". - Colors, shapes and patterns: tap the red car, find the heart, work out which color comes next. TWO WAYS TO PLAY - Train Town: a little town your child can drive round. Every game has its own station with a giant signpost. Drive with the lever, or tap a sign and the train drives there by itself. - The Menu: a simple tap-a-tile menu if your child already knows what they want to play. RIDE AND CATCH Roll through a world and catch letters, numbers, shapes, colors, sounds or words as they appear along the track, in order, with a cheer for every one. Swap engines, toot the whistle, and switch between a chase view, the driver's cab and a bird's-eye view. DELIVER PASSENGERS Pick up animal friends at one station and take them to another. Duck, cow, lion or zebra - everyone gets where they are going. 11 WORLDS TO EXPLORE Sunny Meadow, Fun Park, Palm Island, Big City, Mighty Mountain, Harbor Bay, Candy Garden, Snowy Peaks, Safari Valley, Farm Valley and Sunny Canyon. Each one has its own track, stations, tunnels, villages, bridges and animals. Level crossings really work: the gates swing down, the lights flash, the bell rings and the little cars wait for the train. LOTS OF TRAINS, LOTS OF REWARDS Steam engines, streamliners, trolleys, diesels and a bullet train. Every finished game earns a collectible train sticker. MADE WITH LITTLE HANDS IN MIND - Big, forgiving buttons and tap targets - Gentle hints and encouragement, never a "you lose" - Games quietly adapt to your child: more choices and trickier look-alikes as they improve - Spoken instructions and on-screen captions - Plays without an internet connection PARENTS: PRIVACY AND PEACE OF MIND - No ads.
