Online slot games are played on a series of vertical reels filled with symbols. The reels spin and randomly come to a stop thanks to a random number generator that’s regularly audited for fairness. You win money by lining up matching symbols on paylines that run horizontally (though some games have vertical or diagonal lines, too). Online slots are available in many styles, from traditional three-reel machines to the latest video slots with multiple reels and interactive bonus features.
The classic Cleopatra slot is still a favorite, thanks to its Egyptian theme and music. Its popularity helped spawn a sequel, Cleopatra II, which has different music and up to 50 free spins. Both offer a high RTP and plenty of opportunities to win big.
Besides checking the pay table, players should always look for a slot’s RTP (Return to Player). This figure tells you how much you can expect to win on average, and it takes into account any caps that casinos may place on a jackpot amount. Most online slots will have this information visible right on the game screen, and you can also find it in the help section.
Some online slots have a retrigger feature that allows players to reactivate the bonus round for up to a specific number of times. Then the game will calculate your wins and add them to your real money balance. This way, you can enjoy the bonus round again and again, extending your gaming session.
