Addiction by Design by Natasha Dow Schüll is an excellent book about the video slots industry in the US, its behavioral engineering principles, and the effects it has on the lives of the people it hooks into pointless and expensive dopamine grinding.
Second this rec! I only play poker/blackjack at casinos but after reading Addiction by Design I'm almost scared of even trying a slot machine. The addiction extends to the casinos and politicians who become addicted to the profits generated by the addicts and it swallows the entire industry.
