Rueda: Invent a Kart and Race

Rueda is a side view pixel kart race where you invent the parts. Type a word and it becomes your wheels, and they drive the way the real thing would: jelly bounces over the bumps, ice skids, honey grips, a heavy stone sinks in the water. Try them on the test strip before you race. Fill your pocket with more inventions and throw them at the rivals. Each one works as well as it really would against that rival: a magnet stops the iron kart and does nothing to the balloons, a cat scares the mouse. The starting grid shows what every thing will do to every rival. Nine painted circuits with auroras, volcanoes, leaping dolphins and a toy factory, three cups, thirteen karts and twelve rivals who talk back and hold a little grudge. Jump, dive downhill for speed, flick up for a backflip, and keep every photo finish as a print. In Race studio you build your own course: the world, the holes, the hills, the music. Over two thousand words come already judged inside the app, so it plays offline. A brand new word is sent on its own to our judge server, which asks an AI model what the thing is like. No name, account or device identifier goes with it, and a grown up can switch it off. Funfair Pier, the garage, every invention and one new custom race a day cost nothing. One purchase, shared with Family Sharing, opens the other eight circuits, the cups, every later track and ten custom races a day. No subscription, no ads, no account.
