Arcades absolutely did promote addiction, they just sucked at it compared to today's games.
In a classical arcade, you walk into a darkened room filled with animated CRTs and strange noises. They literally have blinders, designed to shut out your peripheral vision so the game is the only thing in your consciousness. When you die, you have 30 seconds to insert more coins and continue, otherwise you have to start all over from the beginning. Pretty much everything about this is designed to trigger your adrenalin-based threat-and-reward reflexes.
If modern computer games are more addictive, it's only because they've figured out how to trigger even more powerful primal instincts. MMORPGs and MOBAs add a social aspect, and very often a cumulative acquisition aspect (experience, gold, credits, etc). Simulations and worldbuilders like SimCity, Minecraft & Factorio engage our higher brain centers like planning and optimization. Mobile & casual games have figured out how to squeeze gaming into even smaller timeslots within our lives.
It's also interesting how gaming & gambling have converged. It used to be that a slot machine was a machine where you pulled a lever and tried to match up dials. Now you walk into a casino and it basically looks like an arcade, with lots of computerized gambling games on backlit LCD displays, while Internet games like CryptoKitties let you play & trade with real (well, fake) money.
