Match deposit bonuses, or welcome bonuses as there also known, are most frequently used for new players (existing players are generally excluded from a welcome bonus offer) visiting online casinos for the first time. To claim a welcome bonus, players are required to sign up to the casino and create an account to be eligible to collect the bonus offered, you may also have a bonus code that would need to be entered when registering. Each casino will have a minimum and a maximum amount you can deposit to qualify for their best casino bonus offer. The casino will then match your first deposit by a percentage, anywhere from 25% to 400% depending on the bonus offer. For example, if you were offered a welcome bonus of 100% worth up to £500, you could deposit £500 and the casino would match your money using a match bonus, giving you £500 bonus money to play with, taking your total balance to £1,000. Different casinos will offer different percentages: a 50% worth up to £500 would be £750 and a 200% match bonus worth up to £500 would be £1,500.
