How do casinos traditionally use external stimuli (light/sound), while social media uses digital signals to capture attention?

Earlier today I walked past one of those small gaming halls in my neighborhood, and even without going inside I could hear the sounds and see the colorful lights flashing through the door. It instantly reminded me of the time I visited a big casino with my relatives — everything was loud, bright, and designed to keep your eyes moving. Later when I opened my phone, I realized social media kind of does the same thing but in a digital way: bright icons, little red badges, animations, and sound effects that grab your attention instantly. It made me wonder how similar these attention-catching tricks actually are. Do casinos and social apps rely on the same basic principles but just in different forms?
