Elevator Simulator for kids: a calm, hands-on elevator game for little ones. Step inside and take the controls. There are 14 elevators to ride, including a goods lift, an observatory, an aquarium, a launch gantry and a clock tower. Each one has its own look, its own sounds and its own world outside the doors. - Press the floor buttons and listen. The doors slide, the motor hums, and a voice announces each floor. - Open the maintenance panels and fix little puzzles: sort the wiring, replace the dead bulbs, squash the sparks, top up the oil. The cabin gets cleaner as you fix it. - Hunt for hidden treasures tucked away inside every elevator. - Give your elevator its own name. Gentle and safe by design: - No ads. - No account and no sign-in. - Works offline. We collect no personal information, only anonymous usage statistics and crash reports that cannot identify your child. Two elevators, the Goods Lift and the Observatory, are free. One optional one-time purchase, behind a simple parents-only check, unlocks the other 12 elevators. That is all it unlocks; everything else in the app is free. No subscription.
