Slots FAQs

How do online and land-based slots compare?

Land-based slots have been around for much longer than online slots. Online slots offer many benefits but there is one big thing missing – the human element. That is why land-based slots are still popular. Of course online slots have their own benefits:

  • The comfort of playing from home at casinos outside your city.
  • Incredible bonuses and promotions.
  • Frequent and higher payouts.
  • Bigger progressive jackpots.

Where and when did online slots start?

The first slot was the Liberty Bell, created by Charles Fey in 1887. Next came video poker, followed by the invention of the next slot machines with the classic fruit symbol by the Bell Fruit Gum Company.

Electromechanical slots first came in the 1960s, and were replaced by the electronic machines in the 1980s. The random number generator was the next big thing and led to the birth of the progressive jackpot. Online slots came in the 1990s and now in the 21st century we have mobile slots.

Are there any important rules for playing online slots?

Technically, there are not too many rules that govern slots play. There are rules that govern how wins are determined; for instance most slots allow wins only on symbol combinations across the reels from left to right. There are also rules governing the game features but these are more guidelines than rules.

Is there any optimal strategy to maximise your win potential when playing online slots?

There is no particular strategy to win at slots; it is a game of chance. However, a few things can help minimise your loss frequency:

  • Choosing the right game.
  • Understanding the payout tables.
  • Efficient bankroll management.
  • Avoiding credit-based play.
  • Playing with restraint.
  • Knowing when to walk away.

Which is the best option – download or no-download slots?

Both the options have their own merits, but the world is rapidly moving away from the download option. Platforms like Microgaming continue to offer games in both download and no-download modes, but technology has evolved and the no-download option is being offered exclusively.

The best option today is the hybrid casino, where you get the multiplatform option. Multiplatform casinos are rapidly gaining in popularity because they offer games from all the leading software providers together, giving you a wider range of the best games to choose from.

Mobile vs Online Slots – what do I need to know about playing on my smartphone or tablet?

Now you can play slots directly from your mobile device on the go. This is a huge advantage over online slots, where you can access the games only from your computer or laptop, from a designated location.

The game range is still high in online slots but the mobile casino industry is catching up. Microgaming for instance offers more than 350 of its games on the mobile platform. The quality of slots is still high and payment and customer support is the same as at an online casino.

What is the Return to Player (RTP) Percentage or House Edge?

The RTP is the amount of money a player can expect to win back from the total amount wagered on a slot. It is described as a percentage value and is directly related to the house edge. The higher the RTP, the lower the house edge. For instance, if a game has a RTP value of 95% the house edge will be 5%.
