A short answer to "How RTP works in slots?": set a limit before it is needed. Deposit limits are the most widely offered tool for keeping gambling spending under control, and most casinos also offer limits on losses and on total stakes. Each runs over a daily, weekly or monthly period, and each behaves differently when a player wants to change it. Knowing which limit fits which habit, and how quickly a change applies, makes the tool work as it should.
Casinos also impose limits of their own. New accounts may face a cap while their documents are still under review, and many licences now require affordability checks once deposits pass a threshold, asking for proof of income or a bank statement. A casino can also lower a player's limits after spotting signs of harm, such as rapid deposits late at night. These measures are set out on the safer gambling page, along with how to contest them.
A loss limit counts net losses instead of deposits: stakes minus winnings over the period. It lets a player keep playing with winnings while stopping further losses once the set amount is gone. Some casinos apply it to all games, others to certain products only, such as slots or live tables. Because it depends on results, it can end a session suddenly, and the account page shows how much of it is left.

At nearly every casino a reduction applies immediately, unlike an increase, which has to wait out a delay first.
The account page shows how much of each limit remains, which matters with a loss limit because it can end a session suddenly.
An increase or removal applies only after a waiting period, commonly twenty four hours and up to seven days, sometimes with a second confirmation.
Yes. Some casinos offer a limit on the size of any one bet, usually on the same settings page as deposit and wager limits.
