English Other Gaming/Video-games/E-sports bingo game

Here's some context.

From a basic electronic bingo system with ball timer and one simple ***flashboard*** to the latest computerized systems with touch-screen controls, ***flahsboards*** of various sizes, multiple color TV monitors, and system printers, Gameco has the experience to recommend, design, . . .

How to play
To view the ***Flash Board***
Press ***Flash Board*** key to see the numbers you’ve entered
To return, press Look at Cards.

I'd like to receive an explanation by a native speaker, and a relevant image, if possible :)

Thanks!
