How Slot Features Work

Oct 12, 2022 Gambling

When playing slots, the features on offer should make the game more exciting. These features work to increase the chance of hitting a winning combination of symbols, give guaranteed wins, or trigger bonus rounds. Knowing how these features work will help you understand the potential of a game. Below, we will go over the main types of features found on slots.


Multi-coin slot machines are designed to encourage players to spend time on the machines. This strategy is used by casinos because they know that slot machine play brings in the highest profit margin. Multi-coin slots feature multiple lines and multiple coin denominations, which help to maximize the time players spend on the machines.

Multi-coin slot machines are not as common as traditional slots, but you can still find them in online casino game menus. Players who want to play multiple paylines will benefit from multi-coin machines because the payouts are more equal. Moreover, multi-coin slots often have higher RTPs, or return to player. This figure is the opposite of the house edge, where the casino keeps 4% of all bets.


Buy-a-pay slots are those machines that require players to purchase more than one coin in order to activate a winning combination. These types of slots are more expensive than traditional ones, and can offer payouts of $25 or more. As such, players must read the paytable very carefully before playing. Otherwise, they may accidentally play less than a full coin, accidentally hit the spin button, and then realize later that they had dropped the coin. To avoid this, players should press the bet one button instead of the spin button.

Buy-a-pay slots are becoming increasingly popular. Many of them feature bonus features to increase the odds of winning. These bonus features may include wild symbols and scatter symbols. These symbols can increase your odds of winning by substituting for all other symbols in a payline.

Random number generator

The random number generator is an electronic component of slot machines that determines the odds of winning a spin. Its purpose is to ensure fairness in the game by choosing a random number thousands of times per second. If a player hits a winning combination, the electrical current is stopped and the winning number is displayed.

The RTP of a slot machine varies depending on its features and settings. A high RTP will give a player a greater chance of hitting a combination, but it does not guarantee big wins. It will, however, increase the chances of a small win.

Bonus events

Slot bonus events are special features found in video slots that award the player with extra credits or prizes when specific symbols appear on the payline. These events can be lucrative, and some are more difficult to trigger than others. For example, progressive jackpot slots offer players the chance to win a large prize by hitting a specific combination of symbols on a payline.

These events are also referred to as one-pick bonuses. For example, a slot game themed around African wildlife might feature a one-pick bonus event, wherein the player has to choose one of three animal symbols. The bonus is then awarded randomly by the game’s random number generator. Players who choose a single animal will win 25 credits, while players who choose more than one animal will receive a higher number of credits.
