I suggest you visit https://play.realbridge.online/camera.html which will check your webcam and microphone. Note, nothing to stop you playing without these if you don’t have them or don’t wish to use them. However, use of them will provide a better experience.
See https://realbridge.online/player-guide.html ( or visit https://realbridge.online/ and select “How to.../Player guide”) .
