Online slots are games of chance based on the principle of random number generators (RNG). They can offer a wide range of features and bonuses. Key features of modern online slot machines include wild symbols, cascading reels, and multipliers. These are all designed to increase your chances of winning big.

Cascading Reels

Cascading reels are a popular feature used by many online slots. These games allow symbols to disappear when a winning payline is hit, allowing new ones to replace them and trigger additional wins. These symbols may also appear during bonus rounds, triggering further prizes and increasing your chances of winning. They are also a great way to increase your win multipliers and can lead to bigger prize pots. This gameplay mechanic has been incorporated by slot providers such as Playtech, Microgaming, IGT, and Quickspin. They each have their own spin on it by combining it with Multipliers, Megaways engines, and Free Spins.


Multipliers are a great way to boost your winnings in online slots. These features multiply bets, line wins, and total wins by a certain amount to give players a huge increase in their profits. They are triggered by certain symbols during the base game and bonus rounds and are especially prevalent in free spins games.

They also come in a variety of forms, including progressive multipliers and bet multipliers. A progressive multiplier is one that increases in value when you hit winning combinations. It’s often found in games that feature a tumbling or cascading reels system.

Scatter Symbols

A scatter symbol is a feature that can trigger bonus games and other fun features in online slots. Unlike other symbols that must be lined up on a payline to win, scatters can appear anywhere on the reels to award free spins or other bonuses. These bonus features can be very rewarding for slot players, and the exact way they function varies from game to game.

However, many slots require that three or more scatter symbols must land on the reels to unlock a feature such as free spins or mini-games. Bonus features have the potential to be highly rewarding and calculate payouts as a multiple of your bet on an active pay line. For example, it’s not uncommon to find slots offering a winning payout of x100, x200, or even x500, the original stake amount, when hitting five scatter symbols on an active payline.

Bonus Rounds

Bonus rounds are a great way to boost your winning potential. They’re free to trigger and often come with extra reels, free spins, or an entirely new game screen. They’re triggered by landing specific symbols within the base game. These can be dedicated symbols, scatters, or wild symbols.


Depending on the game, you may need to get a certain number of these special symbols to unlock the bonus round. Some bonus games also have multipliers hidden behind the special symbols. The bonus rounds in online slots have become a popular feature. They’re a great way to increase your win potential and make the game more fun to play. These bonuses can be found in both free and real money games and are available across many different slot machines.


Slot are a popular casino game and are great for both new and seasoned players. They are highly entertaining, offer incredible rewards or bonuses for playing, and are often updated to keep them dynamic and technologically advanced. The Return to Player, or RTP, of any slot, is a measure of the percentage of money a machine is programmed to give back to its players. This number should be clearly displayed on all slots. Slots that have a higher RTP tend to pay out more money but less often. This is because they are programmed to have frequent smaller hits in order to compensate for the big wins.
