Normally I think those are called "electronic games", as were the earlier games that just used LEDs (like the famous Mattel "Electronic Football" from the 1970s that had you control an LED representing an American football quarterback trying to get touchdowns without being tackled by opponents, also LEDs). Video games are electronic games, but not all electronic games are video games.
