Tiny electric cars, big chaos. Enter a name, press Play and you are in: you take over an E-Car in a race that is already running, against up to 7 other players and bots. Players on iPhone, iPad and in the browser all meet in the same races. DRIVE ELECTRIC Your battery drains as you drive, and every hit costs energy. Grab the batteries that pop up on the track, steal energy with a well-timed ram, or take the detour through the Charging Station for a fast top-up under its speed limit. Run dry and you are stranded: the world turns black and white until a drone flies in and recharges you where you stand. RAM, ZAP AND DRIFT Shove rivals off the racing line, drift through the bends, splash through puddles and fly off the jumps. Item Boxes help the chasing pack: a Zap with five shots, a Missile, a Mine or a Shield. Fall off the track and you are back at the last checkpoint. LEADING IS HARD The leader is slowed as soon as they pull away, second and third get a tow, and every bot behind a human leader takes aim. Races stay close right to the line. 50 TRACKS IN 22 PLACES Race across the kitchen table, through the garden, over the office desk and round the bathtub. Then head out: four tech offices, a LAN party in the dark, a golf course, a soccer field, London, New York, Paris, Las Vegas, Berlin, Heidelberg, an Indian kitchen, Hollywood, San Francisco and two villages in the German countryside. Each place has its own landmarks, and the tracks have climbs, jumps and bridges over rivers. Pick one on the start screen, or join whatever race is on. FIVE E-CARS Roadster, SUV, Microbus, Pickup and a Semi with its trailer: from quick and twitchy to slow and heavy with a huge battery. Heavier cars win rams and shrug off hits, bigger batteries run dry less often, so each of them can win. MADE FOR THUMBS Your E-Car accelerates by itself. Hold a thumb left or right to steer, and tap the one action button to fire or use your item. Choose Buttons or Slider steering and which corner the pad sits in, and try them out on the Practice Ground first. On iPad, a hardware keyboard or a game controller works too. NO CONNECTION, NO PROBLEM When the server cannot be reached, you race the bots offline. APPLE WATCH Race the bots on your wrist: steer with the Digital Crown and tap to use your item. A cel-shaded comic look with bold outlines, a chiptune soundtrack and cartoon voices for every racer. No account, no ads, no in-app purchases. Just race.
