What Is an Online Casino?

An online casino is an internet gambling room where you can deposit funds via bank transfer, credit/debit card or prepaid cards.

Online casinos usually offer a deposit bonus upon registration that doubles or triples the first deposit you make.

These bonuses are usually associated with a wagering requirement that you must complete before withdrawal of any funds.

The most common thing is that people use their Visa or Mastercard. However, it is becoming increasingly popular to use a mobile billing method on online casinos.

There are some slight fees to these options which is not necessary at all times. E-wallets are another option that quite a few players use.

Mobile Casino

Many players today choose to play through their mobile rather than the computer.

The amount of mobile casino users are increasing every year, so this is a natural development.

The good thing is that the casino industry is definitely keeping up with this development.

All casino slots and table games are accessible from multiple platforms such as mobile and tablets, and casinos make sure that they are accessible through these devices.

Known International iGaming Licenses

The most known iGaming licenses in the industry right now that casino sites use are the following:

  • MGA – Malta Gaming Authority
  • UKGC – United Kingdom Gambling Commission
  • CGL – Curacao Gaming Licence
  • SI – Spelinspektionen

These are the most used licenses in and around Europe.

Some of the above-listed licenses allow you to operate in unregulated markets which is a big reason that they are still frequently favoured by casinos.

Zamsino is a well known online gambling guide that has been the best choice for many gamblers for years.

We regularly update our top casino list with new casinos each month.

Playing With Real Money Online

Many online gamblers are cautious before depositing their money into a new online casino.

It is not often someone stumbles onto a casino and start playing there.

It is recommended that you claim no deposit bonus funds before you play with real money because you tend to get a very real feel of the casino site by playing online slots for free first.

When you have long free spins-lists like ours at Zamsino, you can pick your favourite pokie machine and then search for which online casino has a no deposit offer available.

The common free slots offers often included these three casino games:

  • Book of Dead
  • Starburst
  • Gonzo’s Quest

Best Online Casinos

We rate online casino on several factors, including:

  • Welcome offers.
  • Reliability.
  • Stability.
  • Security.
  • The number of online casino games.
  • Customer support.

If a casino is in our current top 20 casinos, you can be certain that they place above average in all of these categories.

Rating casinos is no easy task, as it requires a lot of time and dedication.

Which online casino that is the best for you can best be figured out in one way: try a couple out with free spins offers.
