In the past few years, there has been a large increase in the number of online casinos popping all over the Internet, leading to a very saturated market with a huge number of casinos competing to convince online gamblers to sign up with them. This degree of competition has made the online casino market a far more welcoming place for gamblers looking for great sign-up deals when compared with any previous time in the market.Big Sign-Up BonusesThe majority of major online casinos are now offering gamblers large sign-up bonuses as a welcome gift to start playing at their particular casino. These sign-up bonuses can be as little as £50 and go all the way up to £400 or more. Some of the bonus amounts offered are dependent on how much money you initially deposit with the casino; however, certain sites are handing out large sign-up bonuses with no strings attached.Improved Interfaces and User ExperiencesThe increase in competition, added to the sheer number of people now regularly playing at online casinos, has meant that the overall playing experience has improved for players across the majority of online casinos. However, it should be noted that smaller online casinos are more likely to go out of business due to the smaller margins across the industry.
