Gambling is a fun and exciting way to pass the time, but you should always remember that gambling is a risky activity. Even if you win, you won’t be able to recover your losses, so it is important to gamble responsibly.
When playing at a casino, always test the machine’s payout percentage before you put in any money. You can usually find this information on the rules or information pages for the game, or by doing a search of the name of the game and “payout percentage” or “return to player.” If you have a lot of break-even spins, that indicates low volatility. If your wins are frequent but small, the game has high volatility.
