Chance-based games are games where the outcome is primarily determined by random events rather than skill or strategy. Examples include games like lottery, roulette, and slot machines. Players participate with the hope of winning prizes or money, but the results are unpredictable and rely on luck. These games often involve betting or wagering, where players risk something of value for a chance to win more. Chance-based games are popular in casinos and online gaming platforms, attracting players who enjoy the thrill of uncertainty and the possibility of a big win.
