Online casino games offer a wide variety of slot options, but they all work the same way. After you place a bet, the reels spin and random symbols appear on the screen. The more identical symbols you line up, the higher your payout. Some slots have special features that increase your chances of winning, like wild symbols and scatters.
When you’re ready to try your luck, select a slot game and read its pay table. This is a list of the symbols in the game, their pay values, and how to line them up. If the game has any bonus features, the pay table will also explain how to trigger them. You can find this information on the game’s homepage or in its help menu. Some casinos also list the software providers they use; this can help you find sites that feature similar games.
