Can you cast a bingo game to a TV?
Yes — any browser-based bingo caller can be put on a TV, either by casting the browser tab from Chrome to a Chromecast or smart TV, or by connecting the device to the TV with an HDMI cable.
There is no dedicated cast button to look for: you cast the browser tab, not an app. Open the SnapBingoX caller, press its full-screen button so the current number fills the display, then in Chrome open the three-dot menu, choose Cast, and pick your TV. Chrome's cast-a-tab option carries the tab's audio too, so the spoken calls come out of the TV speakers.
HDMI is the more reliable option in a hall with weak Wi-Fi. Plug a laptop or tablet into the TV, mirror the display, and put the caller in full screen.
Full-screen mode exists for exactly this: the current call is shown large enough to read from the back of a room, and the history of numbers already called stays visible beside it, so latecomers and anyone who missed a call can catch up without asking.
