How do online slots work?

The main aim when playing online slot games is to create winning combinations along one of the pay lines. You place your bet and spin the reels.

If the winning combination appears, you win. Your winnings depend on the winning combination that you’ve managed to create.


To increase your chances of winning, you can bet your money on multiple pay lines. You’ll only receive points when a combination of symbols falls on pay lines.

The more pay lines you bet on, the greater the chance is that a combination will land on one. The number of pay lines differs from slot to slot. This can range from one to dozens of pay lines.

Bonus symbols

Bonus symbols make playing slots even more enjoyable. These, as the name suggests, offer extra bonuses. Different slot machines may have different bonus symbols. There are two standard symbols: the wild, and the scatter symbol.

Wild Symbol

This symbol can replace another symbol. This means that the chances of forming a winning combination are higher. The way this symbol looks differs from slot to slot. A wild symbol cannot, however, replace another bonus symbol.

Scatter Symbol

This symbol can initiate free spin modes.  Depending on the slot machine and the number of scatter symbols, you can sometimes receive up to 50 free spins. This means you’ll be gambling for free! Scatter symbols can also yield big wins by multiplying your bet with other factors.

Bonus games

Video slots often contain a bonus game. These enable you to win more points by interactively playing a game. To get to the bonus game, you need to collect bonus symbols.

These can be the scatter symbols or another bonus symbol. The number of bonus symbols requires differs from slot to slot. Sometimes it’s possible during a bonus game to win a progressive jackpot.

Tips and Strategies to Play Slots

  1. Understand RTP (Return to Player): The RTP is a percentage that indicates how much a slot pays back to players over a large number of spins. Higher RTP games offer a better return over the long run. However, remember that slots are games of chance, and the RTP is not a guarantee of winning.
  2. Manage Your Bankroll: This is crucial in any form of gambling. Determine beforehand how much you are willing to spend, and stick to that limit. Also, never chase losses, as this can lead to you spending more than you can afford.
  3. Play Free Slots First: Before wagering real money, try playing the free version of a slot. This gives you the chance to familiarise yourself with the game, its features, and its payouts without risking any money.
  4. Understand Volatility: Slot games can have low, medium, or high volatility. Low-volatility games offer more frequent but smaller wins, while high-volatility games provide less frequent but bigger wins. Choose a game with a volatility level that suits your playing style and risk tolerance.
  5. Look for Good Bonuses: Many online casinos offer bonuses that can boost your bankroll. Look for good welcome bonuses and regular promotions, but always read the terms and conditions, as these bonuses often come with wagering requirements.
  6. Play Responsibly: Always remember to play responsibly. Set time limits for your gaming sessions, take regular breaks, and never gamble with money you can’t afford to lose.

Final Thoughts

As with all forms of gambling, it’s important to play responsibly. Remember to set limits, never chase losses, and most importantly, have fun.
