Types of Online Casino Bonuses

Online casino bonuses generally fall under one of a few overlaying types; As the online casino player, you should pick the one that best fits the intended games and size of deposit. The common types of online casino bonuses are:

• Matched deposit casino bonus – The most common and straightforward type of online casino bonus offers, the online casino will match a first deposit up to a certain amount, i.e. a 200 casino bonus means that the first deposit will be matched with bonus funds up to £200
• Welcome packages – Similar to the match deposit bonus, normally applies to several deposits after the first, with varying percentage of each deposit matched. A bonus of £2025 Welcome package would normally be split over four deposits, with varying amounts and percentage limit to each deposit.

• Free Spins – Free spins will often accompany other bonus elements as an added incentive, these free spins will generally not yield any winnings but if a player is lucky they might provide a small initial bankroll for when you are trying out a new online casino.
• Deposit/Spend X and Get X – In terms of percentage returned these bonuses will usually provide the best odds but the amounts offered are small and releasing these bonuses is usually more difficult then the matched deposit bonuses.

Opening an Online Casino Account

Opening an online casino account for UK users is a rather painless process, basic information that includes full name, address and phone number are basically all that is required when registering for a new account. The next step is making a deposit, which will of course require the submission of a payment method which can at most cases be either an e-wallet, personal credit card or debit card of almost any kind. Debit cards can be especially useful as they can help keep gaming funds separate from day to day monies and allow for greater control and monitoring. As you become a regular player and make multiple deposits and withdrawals the online casino operator is required by law to confirm the identity of the account owner which can at times be a bit arduous as scans and documents aren’t always as sufficient as one would expect.

Online Casino Vs Brick & Mortar

The choice between an online casino and an old school b&m is one that comes down to personal preference, often dictated by the social situation but there are also objective differences that are with examining and make the online casino a much more viable option the vast majority of the time

• Online casinos are always available – a real life casino requires a commitment from the player while an online casino is available 24/7 be it sitting on the john or boarding a flight.
• Online casinos offer more variety – A live casino is limited by it’s floor space and there not be more then a handful of options even in heart of London. Online casinos however can offer endless amounts of games, there is never any wait and stakes can vary to a much higher degree.
• High rollers get better treatment – This is a common misconception when people consider the two casino options, although the past ten years have seen live casinos initiate reward programs in an attempt to combat the reward schemes of online casinos, online casinos still provide a much superior compensation package for new and regular visitors alike
• Deposit Bonuses – Perhaps the biggest difference and the main reason why playing at an online casino is a much more viable proposition.

The first set of deposits will usually garner healthy multipliers that can amount to thousands of pounds.
