How to play

RacingCart3D is free 3D kart racing designed for a shared living-room display. Open CastPlayTV on the Main screen to host the race view, then invite up to four players from their phones. Each phone becomes a steering controller while the TV shows the 3D track, karts, and finish drama. Play solo for a practice lap or pack the grid with friends for a split-attention party race. No console, disc, or native app install is required — the host browser renders the world and phones send steering input over the live session. Pick a track, wait for the countdown, and race to the finish. Rematch when you are ready so the next heat starts without rebuilding the room. RacingCart3D fits couch co-op energy: one spectacular screen, phones as controllers, and a setup that takes about a minute. It is especially fun when guests do not want to create accounts or download stores apps just to race for ten minutes.

What you need

One Main screen (TV/laptop browser) and 1–4 phones for steering. Network access and a modern browser; no gamepad required.
