Slot machine mechanics are very good at extracting money and time from people who would likely become addicted to slot machines if they were legal and available on their phones. But the f2p games have carefully programmed reward/spend paths that casinos only dream of. What I want is for gacha/slot machine-like mobile games to be required to disclose the odds, as well as the expected cost/time, for various rewards, much as casinos are required to disclose the odds and expected loss per hour.
